Saving SpaceThe unique shape design increases the area and efficiency of heat exchangers. Moreover, it ensures smooth air suction of the heat exchangers and enables the compact horizontal installation of several modules, so the installation space is optimized.

Ultra EfficiencyWith the DC inverter, the unit can always ensure high efficiency under part load. With the stepless capacity modulation, the unit achieves a larger integrated part load value (IPLV).

Modular DesignBased on the module UAL340 (100 kW), up to 20 modules of the same model can be combined to meet different load and design needs for various buildings.

Environment FriendlyThis unit adopts the chlorine-free refrigerant R410A, harmless to the ozonosphere and friendly to the environment. While the electricity consumption of the unit is decreased, the carbon emission is reduced, slowing down its impact on greenhouse effect.

UAL-AR5 can be installed in an irregular space.A large integrated air-cooled chiller cannot be easily installed in an irregular or limited space. On the contrary, The unit can optimize the use of installation space owning to its unique shape. As shown in the following figure, the large integrated units cannot be installed on an irregular roof, but nine units of UAL340 with the same cooling capacity can be installed on the roof.

37m2→28m2

The installation space of a 400 kW UAL340 system is about 25% smaller than that of an integrated air cooled chiller with the same capacity.

20 UAL340 units cover an area of 116 m2

The integrated air cooled chiller covers an area of 150 m2

Saving SpaceGlobally Initiative Unique Shape

Innovative Shape DesignWith the unique hexagonal design, the area of heat exchangers is increased in the limited space and several units can be closely installed horizontally, so the installation space is optimized.

Comparison of Installation SpaceThe unit greatly optimizes the use of installation space. It saves much larger space than the traditional integrated air-cooled chiller does.

The installation space of a 2000 kW UAL340 system is about 23% smaller than that of an integrated air cooled chiller with the same capacity.

Fit for Systems with Large Temperature Difference

The inlet and outlet water of UAL-AR5 varies from 5°C to 10°C which meets design requirements of all types of HVAC systems. This temperature design can cut down the initial investment in water system, and largely reduce system operation expense.

EER of UAL-AR5 under Part LoadAccording to the IPLV, the air conditioning system operates under partial load of 30% to 80% most of the time.With the DC inverter compressor and the inverter controller and other technologies, the unit can achieve the highest energy efficiency ratio (EER).

Outstanding Energy Saving PerformanceThe unit is eqiupped with the DC inverter, the new efficient heat exchanger, and the advanced inverter modular controller to achieve the highest EER under part load. The IPLV of the pump is up to6.6, and the COP 7.8 under the IPLV working condition, indicating that this unit is more outstanding in energy conservation than the traditional capacity product.

Modular DesignTo Meet Various Needs

Modular Design to Meet Various Needs*The unit can be implemented with up to 20 modules of the cooling capacity of 100 kW to 2000 kW. Thanks to the modular design, modules of the same type can be combined, and then applied to different designs to easily meet all types of market demands.Note: the function with* can only be achieved with a modular controller.

Start at Low Frequency to Impact Less on Power GridWhen a traditional speed-fixed unit is started, the current is much higher than the operating current, which significantly impacts the power grid. On the contrary, when the unit is started with low frequency, the current is lower, which impacts less on the power grid.

Smart Defrosting*The unit can achieve alternate defrosting of multiple modules, without affecting the temperature of supplied water. Moreover, the indoor fan coils don't have to be stopped, without affecting the normal operation. On the contrary, when the integrated air cooled chiller shifts from the heating mode to the cooling mode to start defrosting in winter, the master unit along with the indoor fan coils must be stopped, affecting the normal operation.

Defrosting

Electrical Cabinet with DoorThe electrical cabinet can be opened by a special door, which is an innovative design for space optimization and convenient maintenance.

The unit can reduce 26% carbon emissions than that of a capacity-fixed air cooled module with level-2 energy efficiency. Supposed that 30, 000 traditional modules can be sold in a year,300,000-ton carbon emissions will be reduced every year by replacing traditional modules with this unit.

Note: ● Nominal cooling capacity is tested under following conditions: outlet water 7°C, water flow 0.172 m3/(h*kW), and ambient dry-bulb temperature 35°C.● Nominal heating capacity is tested under following conditions: outlet water 45°C, water flow 0.172 m3/(h*kW), and ambient dry/wet-bulb temperature 7°C/6°C.● * The capacity range of unit is calculated under the nominal cooling or heating conditions, and is subject to changes of operating conditions.● Water resistance of the unit includes the water pressure drop of the unit and the accessary Y-shape filter.● The factory doesn’t supply the water pipe, so the water pipe of the combined unit must be made and installed on the site. The pipe size must comply with the

design standards.

The water-side volume of the pump 26 L

If there is a by-pass loop, the water volume must be above a certain value due to the two-way valve and the three-way valve. The value is based on minimum load when water temperature is 2°C and water temperature control precision is ±1°C. (The system runs for two minutes and stops for three minutes.)The minimum water volume is for protecting the system. If the water volume is small, the temperature precision may be wrong when the pump is started or stopped.● If the water temperature is set as 1°C, the water volume of the water system must be 2 times of the minimum water volume, and the water flow of the cooling/

heating water circulating system must be larger than the nominal water flow.● : Indicating that the temperature precision is lower under the low-load condition.
