Ventilation with Heat RecoveryDee Fly Single Detached Housing

HRV - Principle

The air renewal is guaranteed mechanically

with air supply into the main rooms and air

exhaust from the sanitary areas and the kitchenthanks to a ductwork and grilles.

Thanks to the heat exchanger 90% of the

calories of the exhausted air are used to pre-heat the supplied air.

Heat Exchanger Principle

The heat exchange is done through the plates.

Exchanger plates

Exhaust air

Fresh air


5/41



Cross-flow exchanger, efficiency ~ 70%

Air exhaust = 20 COutdoor air = 0 C

Air supply = 14 CAir discharge = 6 C


6/41



Counter-flow exchanger, efficiency > 90%

Air exhaust = 20 COutdoor air = 0 C

Air supply = 18 CAir discharge = 2 C


7/41



The global efficiency of the heat exchanger is

linked to :

The airflow

The exchange area

The space between the plates

The humidity level (condensation, up to +10%

efficiency)

TemperaturesTC air supply - TC fresh air

TC air exhaust - TC fresh air =

Airflow Regulation thanks to the Motor

Airflow selection according to the quantity

of sanitary areas

The motor adjusts its speed to guarantee

this airflow

Limitation of the motor couple to avoid an

overconsumption

Installation

In-line

Allows the installation of the motor in the

attics

Makes the integration of the heat

exchanger in the heated area easier

Installation

Boiler assembly

Makes the installation in a cellar easier

Connections on the top side

The Condensates

In the winter the heat exchange between acold airflow and a hot and humid airflow

causes the development of condensation

It is necessary to evacuate it

Connection for condensate evacuation

integrated in the Dee Fly casing for each

type of installation


28/41


The Condensates

Ceiling installation

Evacuation from the bottom side


29/41


The Condensates

Installation on the floor

Addition of a piece to protect the

evacuation and guarantee the tightness

The Condensates

Hoizontal installation on the wall

Addition of a water recuperation tray

Evacuation from the bottom side

The Defrosting

Risk of condensates frosting when the

outdoor temperature < 0C

When using micro-watt version,decrease ofthe fresh airflow to facilitate the defrosting

When using the standard version, use of an

electrical coil integrated in the motor casing

Why to require the new

HRV ALDES ?


33/41


Indoor air quality :Filtered fresh air = healthier and less dirty

Thermal comfort :Winter : Heat recovery => nos cold draft and comfort temperaturemaintained in the housing

Summer comfort : Possiblity to associate the Dee Fly with a buried wellto refresh the fresh air (Geothermal Temperation)

Sound insulation :No air inlets in the facade = total sound insulation / outdoor.

The comfort power 3


34/41


Up to 20% decrease of the heating consumption * :With limitating the losses linked to the air renewal Dee Fly allows to

realize savings (up to 200 / year)

Ecological ventilation :Dee Fly recovers the energy from the exhaust air.

Used in association with a buried well: Dee Fly uses the geothermal

energy of the ground to refresh the air during the summer time.

(avoids the use of air conditioning)

Low consumption motorisation micro-watt :New technology of motors which allows a low power consumption

Energy savings and and Ecology

* In regards to a self-balanced CMEV according to the French standard of calculation
