Concrete Application Example two
Be arranged in the same indoor set simultaneously two heat exchangers in the refrigerating plant of this air-conditioner and a shared ducting system, condenser 3 is arranged in the off-premises station.And the heat exchange area that makes first heat exchanger 6 is less than second heat exchanger 7, makes first heat exchanger 6 be in the upstream of the position of second heat exchanger 7 in the air channel, just first heat exchanger, 6 to the second heat exchangers, 7 more close air inlets.
So with respect to the indoor set of common single evaporator, the refrigerating plant of this air-conditioner has the advantage of following four kinds of functions:
The first, powerful refrigerating function: first heat exchanger and second heat exchanger freeze simultaneously, and heat exchanger becomes two by one, and heat exchange area increases, and wind pushing temperature is low, and refrigeration is rapid;
The second, powerful heat-production functions: first heat exchanger and second heat exchanger heat simultaneously;
Three, refrigerated dehumidification optimizational function: first heat exchanger 6 heats and second heat exchanger, 7 refrigeration.Room air is flowed through second heat exchanger 7 again by cool-down dehumidification after suitably being heated up by first heat exchanger 6, can prevent that indoor temperature from reducing the sense of discomfort that causes indoor occupant too much.
Four, heat dehumidification function simultaneously: first heat exchanger, 6 refrigeration, second heat exchanger 7 heats.At this moment, after dehumidifying air, heats through second heat exchanger 7 again by first heat exchanger 6, and then in the inlet chamber.This dehumidification function is more effective than the simple mode that reduces relative humidity of heating up that relies on, and the air of producing by boasting in the dehumidification process is hot-air, and comfortableness is good.
Above embodiment; comprise concrete Application Example; only be the system works principle of refrigerating plant of this air-conditioner of explanation and the effect of the scope of application; the refrigerating plant of the air-conditioner of the application's protection includes but not limited to above embodiment; everyly meet one of description of the present invention or several, all within the application's protection domain.
