ABSTRACT:
The present invention relates to an air-conditioning system with full heat recovery comprising a condenser, an evaporator, a compressor and an expansion valve; one side of the condenser is disposed in a position corresponding to an indoor air outlet and an outdoor air inlet; the other side of the condenser is provided with an exhaust vent; and a cooling fan is disposed between the exhaust vent and a cooling air opening. The present air-conditioning system with full heat recovery can be connected with a condensate recycle system. The present invention utilizes low temperature, low humidity indoor exhaust air as cooling air for the evaporative condenser. It makes use of the sensible heat (temperature difference) of indoor exhaust air as well as the latent heat (humidity difference) of indoor exhaust air, thereby attaining better condensation effects. It also uses the condensate to assist cooling and increases cooling and water saving effects. The present invention can be widely used in the air-conditioning systems in restaurants, hospitals, supermarkets, villas and offices and has wide applications.
