When the indoor air returning from the air-conditioning system and the outdoor fresh air flow across each other in a counterflow configuration through the heat exchanger, the temperature difference and the partial pressure difference of water vapor between the two airstreams give rise to simultaneous heat and mass transfer, thereby driving the total heat exchange process. During summer operation, the total heat exchanger installed in the system extracts cooling capacity from the return air, lowering its temperature while simultaneously drying it and reducing its humidity; during winter operation, it recovers heat from the return air, raising the fresh air’s temperature while simultaneously humidifying it. It is through this total heat exchange process that the fresh air recovers energy from the return air, achieving energy savings.
Heat transfer type:
Sensible heat exchange type: The sensible heat exchanger is made of high-quality aluminum foil with excellent thermal conductivity, offering high sensible heat exchange efficiency and a long service life.
Total heat exchange type: The total heat exchanger is manufactured by chemically treating special polymeric paper membranes, giving it flame-retardant properties and optimal performance in temperature control, humidity regulation, and energy recovery.
Model Description for Fresh Air Ventilation Units
Product Technical Features:
Two-way ventilation technology:
Equipped with built-in supply and exhaust fans for bidirectional, equal-volume air exchange, this system suppresses indoor temperature fluctuations and ensures a continuous supply of fresh air.
