Description

The cold and hot window air conditioner of taking into account

Technical field

The present invention relates to a kind of window air conditioner, especially a kind of package AC plant of pump type heat.

Background technology

Existing window air conditioner internal structure is isolated into indoor unit and outdoor unit two large divisions usually, and indoor unit mainly holds indoor heat exchanger and indoor fan, and outdoor unit mainly holds compressor, outdoor heat exchanger and outdoor fan; Single cold type window air conditioner indoor heat exchanger is fixed as evaporimeter, outdoor heat exchanger is fixed as condenser, indoor heat exchanger still is an evaporimeter during heatpump windowair conditioner refrigerating operaton, outdoor heat exchanger still is a condenser, change refrigerant flow direction by four-way change-over valve during heating operation, indoor heat exchanger is become condenser, outdoor heat exchanger is become evaporimeter.Because the reason of the restriction of compressor installation site and outdoor fan unidirectional operation, order from outdoor air flows, existing window air conditioner under any duty without exception all some outdoor airs earlier through compressor surface heat exchange pass through the outdoor heat exchanger heat exchange again, discharge at last.The order that outdoor air flows like this during refrigerating operaton will inevitably reduce the coefficient of performance of refrigeration system, because the compressor surface temperature is apparently higher than the condensation temperature of outdoor heat exchanger, behind the outdoor air process compressor surface heat temperature raising is that condenser carries out heat exchange with outdoor heat exchanger again, obviously be unfavorable for the condenser heat radiation, this is that the window air conditioner refrigeration efficiency is than one of lower usually reason; Certainly, the order that flows like this of outdoor air helps the window air conditioner heat pump and heats.But when heating, the window air conditioner heat pump to be subjected to the restriction of outdoor temperature, usually the following window air conditioner of subzero 10 degree can not realize that heat pump heats, even if the heat pump window air conditioner of auxilliary electric type, because auxilliary electrical power is smaller, generally all heat chain with heat pump, usually when heating deficiency, heat pump just can start auxilliary electricity work, and heat pump when not working auxilliary electricity also can not work naturally, the heat supply means that the user must possess other under such situation could solve the problem of heating, thereby can not use heatpump windowair conditioner as main heating facility usually at China's cold district.Though electroheating type window air conditioner heating range is not subjected to the influence of outdoor climate, but heating efficiency is lower than 1 all the time, even if while severe cold area, have the long duration outdoor temperature among 1 year equally and be higher than heat pump and heat the minimum temperature of requirement and can not rationally be utilized and come down to a kind of bigger waste, so the electroheating type window air conditioner more is unworthy promoting.No matter heatpump windowair conditioner all adopts the mode of forced convertion when still to be the electroheating type window air conditioner heat in addition, can have a strong impact on the user during the indoor fan noise nighttime sleep and have a rest.

Common outdoor unit chassis sidewall of existing window air conditioner or end face need drive the air port into, be very restricted so install, unit need stretch out exterior wall one usually and cut greatly, the a part of body of this that stretches out exposes to the sun and rain throughout the year, must influence complete machine service life, and necessary mounting bracket separately, increase many costs; Compressor is installed in a side of outdoor unit usually in addition, and the centre of oscillation of compressor and the deviation of gravity center of unit distance are bigger, causes the noise of window air conditioner to be difficult to all the time reduce.
