This is one of the most valuable products

Energy saving air exchange: Effectively recover the heat energy, which lost by air exchange (fresh air load) ,which can save the cost of air conditioning.
Save equipment: because it can reduce the fresh air load greatly, part of the heat energy can be recovered, the air conditioning equipment can be appropriately miniaturized.
Humidity regulating function: during refrigeration, remove the external air which with high humidity and supply air as close to the indoor humidity. During heating, convert dry outdoor air into indoor humidity, and supply air as close to the indoor humidity.
Comfortable air exchange: indoor temperature changes in little during air exchange. Due to simultaneous air exhaust and air supply, air exchange also can be stable in a highly sealed room.
Sound insulation effect: Body air duct and heat exchange core have sound insulation effect, can prevent outdoor noise into the indoor, or prevent indoor noise to the outdoor, do not damage the office and other public places environment.
Regarding Air exchange method:
Energy recovery and ventilation: heat exchange for outdoor air and indoor air to get close to the temperature and humidity of indoor air and then supply air to the room.

Common Ventilation Issues for

Homes and Light Commercial Buildings

The HRV unit brings a continuous supply of fresh air into a home while exhausting an equal amount of contaminated air. During winter, fresh incoming air is tempered by the heat that is transferred from the outgoing air so you save on energy costs, while during summer, the incoming air is pre-cooled if the house is equipped with an air cooling system.

Supply Only Fan Application

Postive Air Pressure

Forces hot and/or humid air into walls and insulation.

Exhaust Only Fan Application

Negative Air Pressure

The unfiltered air increases risks of mold and causes energy costs to be higher.

Energy saving principle

Heat recovery calculating equation
SA temp. = (RA temp. -IA temp.) Xtemp. recovery efficiency + OA temp. Example: 14.8°C = (20°C-0°C) x 74% + 0°C

Heat recovery calculating equation
SA temp. = IA tmep.-(IA temp. -RA temp.) Xtemp. recovery efficiency Example: 27.8t = 33°C-(33°C-26°C) x 74%
