Compared with motorcar, aircraft and other industrial technologies, BROAD fan coils had nothing to be proud of. However, once you know from the following "comparativism" how much BROAD has contributed to innovations of human air conditioning technologies in the past 100 years, you will have to term it a miracle.

Cooling capacity:1.8~25kW Area coverage: 10~300 m2

Suitable for all kinds of rooms

Health ScienceElectrostatic cleaning, active carbon detoxification, oxygen deficiency protection, interior open design, all by a slight touchAcoustics• The inverter fan is equipped with stepless frequency control. • The ultra-thin aluminum fan blade operates without noise. • If the fan is operating at low speed, you can not hear any noise

but your own breathing in serene nights. Aesthetics• Not gaudy, no show-off, not even one redundancy. Only beauty. • Metal shell and coated with top quality car paint. It will still

appear new after several decades. • 139 varieties available in any color, match well with any interior

design style. Thermodynamics • As the density of cold air is greater than that of hot air, low

position installation of fan coils saves energy dramatically, namely 30-60% in cooling and 10-40% in heating operation.

• Customers can choose from a selection of over 100 varieties for low position installation.Economics• Use a heat meter to measure air conditioning consumption, implement energy saving management, and actualize cost evaluation.• The market price of a heat meter alone is more expensive than a conventional air-con, yet its energy-saving potentials are huge.• The heat meter uses an ultrasonic flow meter to measure the flow rate accurately and constantly. It cooperates with two thermometers at Class 0.01°C to measure cold/heat energy accurately. • Record energy consumption and expenses of the moment, today, this month, this year and last year.Engineering• All pipe fittings that were previously site mounted are now installed in the factory. • Factory fabrication eliminates quality risks and avoids redoing. • Achieving central air conditioning industrialization. Lazybones' Philosophy• Intelligent switch enables year-round operator-free . • Auto on/off per ambient temperature saves both labor and energy.

Fan coils

Note: Features, functions and accessories of all 139 fan coil models conform to this illustration. This product is compatible to any air conditioning system and applicable to both new and replacement projects.

Comparativism• The conventional central air conditioning indoor units (fan coils)

are nothing but a combination of “fan + coil + water pan + shell + filter”. The mesh of their filters is only a little bit smaller than a matchstick. Helplessly dirty inside, they have become seedbeds for pathogens, as their interiors are completely enclosed and never cleanable.

• The conventional split units are similar to “fan coils” with only an additional temperature control. Some products have introduced so called “hi-techs” such as photocatalyst, silver ion…which are usually a hoax.

LoadBROAD standard: 40-70W/m2 for apartments or hotels; 50-80W/m2 for offices; 60-90W/m2 for villas; 80-130W/m2 for shops ,restaurants or lobbies; 130-210W/m2 for theatres, exhibition halls or airports. High load is to be designed for places of high population density, high storey and high ratio of wall to floor area, and places of temporary use (quicker air conditioning effect can be achieved). The total cooling load of fan coils(including fresh air load) could be 15%-30% higher than that of the chiller. Fan coil selection is upon actual demand and doesn’t allow any redundancy. In case it’s insufficient, a fan coil of exposed installation can be easily replaced with a larger model.

QuantityUsually one for each room. 2 units can be considered for room over 100m2. More units make higher investment.

Style Usually a suitable fan coil is readily available to match the interior design once the interior design style is confirmed. The standard color is recommended. If customers want to change it even during the installation, it can be easily replaced with a cover of required color.

Energy savingLow position installation at wall corner can save 30%-60% energy compared with ceiling-mounted installation. Do not select ceiling suspended or ceiling built-in models except for the replacement of old system. Vertical models can be considered for rooms with limited space. Furthermore, heat meters may help facilitate behavioral energy saving greatly.

CostLow position installation of fan coils not only saves operating cost, but also reduces huge investment 1. reduce fan coil load 2. reduce chiller load3. save pipeline and installation cost 4. save building height.

ComfortSome people are even sensitive to very slight noise. If the inverter-controlled motor is adopted, no noise can be heard at low speed. Actually 90% of time air conditioning systems are operating under partial load. The units cannot blow straightly to places where people usually stay.

Features BROAD fan coils consist of 6 series & 139 varieties. A careful study of their features should be made before selection.Product photos and typical applications are available in our catalog.

• Thin series The delicate styled thin series fan coils have a great varieties and present vivid individualities. They can cover an area from 10-200m2. The prices are relatively higher. Curve and Thin Models are recommended for energy saving.Cooling capacity: 1.8kW, 2.7kW, 3.6kWHeating capacity: 2.7kW, 4kW, 5.4kWArea coverage: 10-50m2

• Thick seriesThick series with magnificent styles can serve an area of 20-1500m2. Their prices (per kW or RT cooling capacity) are relatively low. They are not only suitable for low-end places but also medium and up-market locations, especially the Oval Model with specially ordered cover ( such as mirror stainless steel cover, brushed stainless steel cover, or even the luxurious titanium cover). Thick Model is recommended as the priority, which is the most energy saving.Cooling capacity: 3.6kW,4.5kW,5.4kW,7.2kW, 9kW,12kWHeating capacity: 5.4kW,6.9kW,8.1kW,10.8kW, 13.5kW,18kWArea coverage: 20-160m2

• Avant-garde seriesVarious varieties with unique characteristics are completely different from conventional fan coils. They are suitable for places from 10-500m2, and with higher prices. Vertical Column Model and Polygon Model can be wall-mounted or at wall corner, or floor-standing with a retainer (1.8kW model even can be equipped with a cone-tube supporter). In this series Piano Model is recommended as the first choice, as it is suitable for most places with easy installation, small space occupancy (based upon cooling capacity) and energy saving. It can be multi-functional: a food table, a TV set stand, a podium, a reception desk or even a bar counter.Cooling capacity: 1.8kW,2.7kW,3.6kW,4.5kW, 5.4kW,9kWHeating capacity: 2.7kW,4kW,5.4kW,6.8kW, 8.1kW,13.5kWArea coverage: 10-120m2

Fan coils - model selection

• Wall built-in seriesSimplicity is the style, and it can serve an area of 15-500m2. Either wall built-in, floor built-in, or cabinet built-in, especially suitable for complicated public areas. Cellular cover is standard for Wall Built-in Model, but grille cover or diagonal grille cover is optional. Wall Built-in Model is recommended as the first choice for its energy saving. In addition, Wall Built-in Duct Model can connect multiple air ducts up to 2~6 rooms. In this case the initial cost and installation cost are reduced dramatically, which even can be affordable for low-cost houses (ducts are not long, not much dust inside, furthermore, the electrostatic cleaner can kill more than 90% bacteria inside).Cooling capacity: 2.7kW, 3.6kW, 4.5kW, 5.4kW, 7.2kW, 9kW, 12kWHeating capacity: 4kW, 5.4kW, 6.8kW, 8.1kW, 10.8kW, 13.5kW, 18kWArea coverage: 15~160m2

• Ceiling built-in seriesBROAD does not recommend this series due to its non energy saving (fan coils are highly ceiling built-in and whole room space consumes energy). It can be adopted to replacement for old buildings where all the fan coils are ceiling built-in. A special note: this series is not suitable for rooms of 3m+ high because of too much energy waste as well as initial cost waste( the model size of chiller and fan coils has to be increased).In addition, cellular cover is standard for Ceiling Built-in Model and CeilingBuilt-in Duct Model, but flat grille cover or diagonal grille cover is optional.Cooling capacity: 2.7kW, 4.5kW,5.4kW, 7.2kW, 12kWHeating capacity: 4kW, 6.8kW, 8.1kW, 10.8kW,18kWArea coverage: 15-100m2

• Large seriesThe style is designed to impress and inspire. It can serve any spacious area larger than 100m2 with 25m far-reaching air blow. It can be installed at the center or against wall. High Stripe Model even can be at the corner. Both sides of High Board Model have covers accessible to maintenance. It can be used as a billboard. The only inconvenience is that a ladder is needed for maintenance.Cooling capacity: 18kW, 25kWHeating capacity: 27kW, 37.5kWArea coverage: 100~300m2

Options

• CO2 sensorCustomers can select one piece only if several fan coils are installed in the room.

• Ultrasonic flow meterIt can be skipped if the customer doesn’t want to have air conditioning billing and energy saving management.

• Outdoor temp. sensorCustomer can select 1 piece if several fan coils are installed in the room. It is not necessary for a building of closed type which can not be cooled down by opening windows or fresh air.

• Lighting remote controlEach fan coil can control 4 lighting loops. It is not necessary if the customer doesn’t want to control lighting by fan coil remote control or implement illumination management for energy saving through BMS.

• Fresh air valve controlEach fan coil has optional 3-position control interface for fresh air valve upon CO2 concentration.

• Color"Standard" colors of each type are indicated on the first page of each series in the catalog of ‘REDEFINE LIFE’. 7% additional price to be charged for “basic” colors. “optional” colors can be offered on case base, but the additional cost may be very high. Colors can be mixed according to customer’s color palette. Special materials are also available for special orders, such as gold-plating in right figure (it is very expensive with long lead time)

• Remote controlIt controls not only temperature and air speed, but also the room lighting. We recommend one for each room. If several fan coils are installed in a room, one for every three fan coils is recommended. It may not be necessary for public places like hotel rooms.

A. Tips for installation location①Placed high in offices stuffed with desks.②Placed low in high-storey rooms. ③Do not select ceiling built-in models for those

places with rigid cleaning requirements such as hospitals, micro-electronics workshops, bedrooms, etc.

④The place should be good for air circulation of the whole room, and the air outlet cannot face people or bed straightly.

⑤Match the decoration and do not affect the room aesthetics.

⑥Convenient for pipe connection and condensate drain.

⑦Easy for maintenance. B. Tips for piping and wiring pre-installation① Pipes must be laid during construction period.② Copper tubes must be adopted in supply/ return

water pipes. Low temperature braze welding is recommended in connecting the pipes. The A/ C W. pipes should be covered with rubber plastic cold insulation material and non-metal tubes can be used for condensate pipe.

③BROAD pre-installed valve should be installed at the end of pipeline. Water supply valve is also a flow regulating valve which can balance the flowrate of each fan coil. It also has a shutoff function which facilitates filter washing. Filter must be re-fixed after washing.

Note: Please follow the marks to install and make sure not to mix up the supply & return W. pipes, otherwise the coils will be blocked!

④ After completion of whole building installation, keep the chilled water pump running

continuously for min. 5 days to accumulate impurities at each filter. Wash the filters before the Fan Coils are installed.

BROAD Fan Coil Installation Tips

Installation proceduresA LocatingThe designer selects fan coils and decides their installation locations according to room function and decoration style to facilitate the pre-installation work like piping and wiring.

B Pre-installed piping and wiringDuring the construction, A/C water supply & return pipe (with pre-installed valve), condensate pipe, power supply cable, lighting output and outdoor thermometer cable shall be implemented to the installation place of fan coils.

C Shell installationFan coil is to be installed after the room decoration. Handle it with care to avoid any damage. Locate and drill holes on the wall against the screw holes on the shell back first, then insert expansion bolts and mount the unit.

D Pipe connectionConnect the pre-installed water supply pipe, water return pipe and condensate pipe to the fan coils. Flexible stainless steel bellow pipe can be used for water return & supply pipe.

F Lighting cable connectionLeading 9×0.75 mm2 lighting cables from fan coil wiring terminal to 4-loop lighting control can actualize coupled twin connection and control (30W for each loop). Energy efficient lamps are recommended. If the lamp power is more than 30W, an amplifier can be introduced.

H Outdoor thermometer installationLead a 2×0.3mm2 cable from fan coil wiring terminal. Install the sensor outside the window and avoid direct sunshine.

I Controller installationThe controller can be installed on a supporter supplied with the unit, or lead 3×0.15mm2 control cable from the wiring terminal and install the controller onto the wall nearby. The location should be convenient to operate and looks harmonious.

E Power connectionLead 3×1.0mm2 power cable from the wiring terminal to indoor power supply (1.5mm2 power cable to be used for ≥9kW models).

G Indoor thermometer installationLead a 2×0.3 mm2 cable from fan coil wiring terminal and install it onto the wall 2m away from the unit (~1.3m above floor). If the thermometer is too close from the indoor unit, it may indicate air blowing temperature instead of the average room temperature.

Note: BROAD Fan Coils are totally different from the conventional fan coils both technology-wise and function-wise. The following instructions must be strictly followed in installation. BROAD Fan Coils are multi-functional products. Besides adjusting the indoor temperature and purifying the air, it also can actualize automatic on/ off according to ambient temperature, and lighting control through the remote control.All basic functions introduced here (not including optional items) must be installed (as the right diagram).

Note:①All electric materials and methods for installation

must comply with the local codes and standards.②Adopt the embedded PVC conduit inside wall for

indoor wiring layout.③The total cross sectional area of all wires should be

less than 40% of that of wiring conduits.④Power cable can be branched through junction

box, but communication cable can't be branched or intermediately connected.

⑤Eliminate the burr of PVC conduit ends or use jacket to protect wire insulation.Pull the wires evenly in order not to break it.

⑥A proper length should be reserved on wire outlets of junction box, which facilitates wire connection and repair.

C. Tips for shell installation①Keep the shell horizontal with no more than 2 mm

gradient.②The expansion bolts should be strong enough to

support at least 3 times the weight of the shell (as there might be impact when the cover is being opened).

D. Tips for piping connection①Shut off the pre-installed valves (water return/

supply valves), take out and wash water filter, then fix them back.

②Take out the bellow for temporary circulation and send it back to BROAD.

③Connect the pre-installed valves with the fan coil by 2 stainless steel bellows of proper length.

④The condensate pipe must be with a certain gradient. No gradient is needed for A/C water pipes since auto air vent is available in the unit.

Wiring diagram of light control(only connect to L12/L22/L32/L42 when separate control is needed )

Power on inspection①After the installation is completed, check

the settings in fan coil controller item by item according to “Parameter Setting” chapter of the User's Manual.

②Pay special attention to the fan motor noise, outdoor/ indoor temperature and CO2 concentration.

③Check fan coil and lighting on/off through remote control.

A/C hydraulic balance commissioningStart up all the fan coils in the whole building for cooling or heating operation, use an infrared thermometer to test whether the air outlet temperature from each fan coil is the same. Turn up its flow regulating valve or turn down valves of nearby fan coils if the air temperature from a fan coil cannot reach the target. Repeat the adjustment till a hydraulic balance is reached.Generally the valve openness of those fan coils which are closer to the chiller should be smaller.

Air purification commissioningTake out the electrostatic cleaner after operating for a day and check dust collection. If not, there might be some faults. Please notify BROAD or BROAD authorized service provider.

List of site Installation

F. Power on inspectionAfter the proper installation is confirmed, turn on the unit, adjust the fan frequency, test the sound of fan, and check the CO2 concentration displayed on the controller.

A. LocatingThe designer selects the model of fresh air unit according to fresh air solution, and locates the installation position for opening.

B. Making holes in the wallFor new buildings, openings should be reserved according to the design. For existing buildings, mark the position and dimension of openings according to different models, then open fresh air holes, and polish them with cement. After the structure construction, indoor walls and floor flatting get finished, recheck the position and dimension of installation, and immediate modifications are needed if it can not meet the requirements (in order to prevent rainfall from flowing indoor, through-wall hole should be higher on the indoor side and lower on the outer side. They also should look neat and nice).

C. Open-box inspectionCheck the product number, product name and model: inspect the shell and accessories to see if they are complete and in good condition. If there is any damage, please notify the supplier.

D. Shell installationFor fresh air unit: inset the fresh air inlet/ outlet pipe into cement holes, After the cement is hardened and the pipes are fixed, steadily install the fresh air unit.For heat recovery fresh air unit and large fresh air unit: locating the unit to the fresh air inlet/outlet hole,and fix it with expanded bolt.

E. Power connectionLead power cable from the wiring terminal to indoor power supply.

Fresh air unit model selection tips

Tips for fresh air system selection

How much fresh air are we breathing?Staying in a room lacking of fresh air is like living on the sea without freshwater. You can breathe (drink seawater), but will be suffocated to death (thirst). According to authoritative investigations, everybody in the world has more or less suffered from fresh air deficiency (oxygen deficiency), e.g.:• In cold seasons people always close doors and

windows to keep warm and save energy. Their faces turn red, not because of the warmth but of oxygen deficiency.

• In hot seasons people always close doors and windows to keep cool and save energy. People are lethargic, not because of fatigue but of oxygen deficiency.

• The ultimate tightness of doors and windows due to quality advancement in recent years makes oxygen deficiency problem more serious.

• Some modern buildings that appear to be full of hi-techs are still using the conventional “low-tech” design and management of ventilation system, which leads to :• Oxygen deficiency• Toxic gases from refurbishing & building materials,

furniture, carpets can not be emitted in time.• Hundreds of people are breathing the same

mouthful of air that is cross contaminated.• A great number of pathogens are bred inside air ducts.

What kind of houses can breathe?Each BROAD fan coil is equipped with an expensive optical instrument – CO2 sensor to monitor oxygen deficiency any minute. People inhale O2 and exhale CO2, by measuring the CO2 level oxygen deficiency is to be indicated.To “know” is very important, but to “do” is even more. To meet different building constructions, functions, purchasing power and climates, BROAD has developed dozens of fresh air products that are totally different from conventional products but cheaper and more energy efficient. They can solve all fresh air problems comprehensively and let each building/room breathe freely.

What‘s the harm of oxygen deficiency?Deficiency of fresh air inside a room will lead to oxygen (O2) deficiency and carbonic acid (CO2) concentration increase in our blood, causing insufficient O2 supply to the brain, headache, chest pain, cold limb and sleepiness, etc. Extended stay in an oxygen-deficient environment will result in skin-coarsening, premature senility, hypomnesia, slow of response, or most seriously heart diseases, brain damnification and stroke. People in serious oxygen deficiency may even lose their lives unconsciously.

What are the features of conventional “low-tech” modes?

• Just “go with your heart”– do not take even fundamental technical measures (such as CO2 sensor) to verify the design, guide the commissioning and check the operation.

• “30/70 ratio” fresh air –in the whole ventilation system, 70% air circulation is from indoor exhaust air and 30% from outdoor fresh air, resulting in cross contamination. All people in the building are breathing the same air. If someone gets sick, it may pass on to everyone.

• Short circuit between fresh and exhaust air system – the fresh air inlet and outlet are too close. Part of fresh air is expelled before people can breathe it.

• Pathogens are easily bred inside fresh air ducts.• As no technical instrument is introduced, it turns out

not enough fresh air in some places and excessive fresh air in other places (which is energy wasting). It also wastes a lot of energy without using heat recovery devices.

BROAD Fresh Air System Conventional Fresh Air System

Eliminates pollution from outdoors

Outdoor fresh air is purified by electrostatic cleaner and active carbon before entering the room.

Outdoor air incompletely filtered Filters are widely used, which cannot filter micro particles.

Eradicates pollution inside air ducts • Small buildings – the fresh air units can draw outdoor air into each room directly. • Large buildings – fresh air can be supplied to the passages by large-sized air ducts, then pumped into individual room by suction ducts from the interior windows. • In order to match perfectly different construction styles, BROAD provides dozens of products and optional accessories.

Serious pollution inside air ducts • Fresh Air ducts are extended to each room. Air ducts in a mansion may outstretch several or scores of kilometers. The air ducts are mixed and anfractuous, becoming the pollution sources. • The air ducts are not cleaned in years or even the whole lifespan. Pathogens are bred rapidly inside, making the air ducts even dirtier than inside drains.

Well-proportioned fresh air Fan coils and fresh air units in each room are equipped with CO2 sensor, which is monitoring fresh air deficiency and excess 24/ 7.

Unbalanced fresh air CO2 sensors are not used, only a few to be installed in 5-star hotels. It may result in excessive fresh air in some rooms and not enough fresh air in other rooms.

Many alternatives • 5 modes, 30+ products and dozens of accessories available. • Custom design can be made according to building structures, functions, energy saving objectives,budgets, etc. • Suitable for fresh air system modifications of old buildings.

Few choices Only two modes all over the world.

Space saving • “Direct fresh air system” takes almost no space. • “Exhaust air duct system” is 50% space saving. • The space saving cost is possibly higher than the investment on equipment.

Large space taking Air ducts outstretch horizontally and vertically into a building and occupy very large space.

BROAD Fresh Air System vs. Conventional Fresh Air System

BROAD fresh air system solutionFor conventional central air conditioning system, fresh air duct system is very complicated. It looks like blood vessels stretching every corner of buildings. In a large building, there are several dozen kilometers of fresh air ducts. In the past few people noticed what was inside fresh air ducts. In recent years “sick building syndrome” (SBS) broke out worldwide, more and more people learned about it. Before Beijing Olympic Games, the investigation into indoor air quality of more than 10,000 large-scale buildings revealed that less than 1% of fresh air ducts in these buildings were cleaned. Similar situation exists worldwide. Furthermore in those cleaned buildings only less than 40% fresh air ducts can be cleaned even with cleaning robots.

Now, the question we are facing is to develop smaller and more practical robots to clean fresh air ducts, or not to use fresh air ducts completely.

If the first choice is taken, besides technical difficulties, how to afford the costly cleaning fee (approximate USD14/m2, which is nearly the same as an initial cost) and how to stand the polluted air during hundred days between two cleaning intervals, so the only solution to prevent pollution is not to use fresh air ducts.

Applications:Matching with BROAD villa air conditioning or other chillers to provide hot water (external primary heating water heats city water in the tank).

Working principle:The cycling of primary heating water in coils heats the city water in the tank, making the temperature of city water inside reach the setting temperature.The heat exchange coil connects to the primary heating water (60~120℃) from outside devices. When hot water temperature is at the setting temperature, the motor valve will shut off the primary heating water. When the temperature is lower than the setting, the motor valve will reopen and thus heat the hot water. The heating and temperature control are actualized in this way.

Features:• All-copper interior and coil are bacteria-killing.• Hand access hole design, easy to open for cleaning.• It adopts separate hot water tank system to

materialize 30% energy saving than centralized systems. The reason is that the valve will be closed automatically once the hot water is heated to the setting temperature. Thus, heat loss and electricity consumption can be minimized.

• Tanks are installed near the place where water is used so hot water comes out as soon as the valve is opened. It is unnecessary to keep circulation pump running 24 hours a day to maintain hot water temperature.

• Separate tank system maintains stable hot water temperature.

Tips for piping and wiring pre-installation• Pipes must be laid during construction phase.• All pipes except city water pipe must be copper tubes with rubber plastic insulation.• Only BROAD valve set could be installed. Note: Please check the marks to avoid any

mistakes in matching pipes.• After completion of whole building installation,

keep the hot water pump running continuously for min. 1 day to collect all impurities of primary heating water to filters.Then clean all the filters.

Tips for tank installation• Tanks must be installed vertically, wall mounted or floor standing with brackets.• The installation strength of expansion bolts must be at least 3 times more than the operating weight.

D. Pipe connectionConnect the pre-installed primary heating water outlet & inlet pipe, city water make-up pipe and hot water outlet pipe to the hot water tank through bendable stainless steel bellows.

E. Electrical wiringLead power cable from the wiring terminal to indoor power supply. Lead 485 communication cables in if there is a central controller.

C. Tank installationRL100 and RL200 are usually wall amounted, or floor standing installation with a bracket, while RL300 and RL500 can only use brackets. After the building decoration, screw hole lofting of wall fixture or brackets, drilling, expansion bolts installation, fixing wall fixture or brackets, and tank installation shall be conducted step by step.

J. Power on inspectionAfter the proper installation is comfirmed, turn on the unit to check whether the controller and temperature control are OK.

A. LocatingThe designer selects hot water tanks according to requivement for hot water,and decides the installation location to facilitate the pre-installation work.

B. Piping and wiring pre-installationA/C primary heating water outlet & inlet pipe, city water make-up pipe, hot water outlet pipe, drain pipe, power supply cable and 485 communication cables should be pre-installed during construction.

F. Controller installationUsually the controller is installed on the supporter attached with the unit. Another way is to lead a 3×0.15mm2 cable from the wiring terminal and install it onto the wall nearby with convenience for control and without undermining the indoor decoration design.
