Detachable air conditioner is a kind of air-conditioner that often adopts.As shown in Figure 1, detachable air conditioner is made of indoor set 1 and off-premises station 7.Be provided with indoor heat exchanger 2 and indoor fan 4 in the indoor set 1; Be provided with outdoor heat exchanger 8, outdoor fan 9 and compressor 14 in the off-premises station 7; The liquid in-out end of indoor heat exchanger 2 utilizes fluid pipeline 12 to be connected with the liquid in-out end of outdoor heat exchanger 8, and the gas in-out end of indoor heat exchanger 2 utilizes gas pipeline 13 to be connected with the gas in-out end of outdoor heat exchanger 8; Fluid pipeline 12 is provided with two-port valve 5, capillary 10 and filter 11, and gas pipeline 13 is provided with triple valve 6, four-way change-over valve 15 and compressor 14.
When detachable air conditioner heated, gas refrigerant was pressurizeed by compressor 14, becomes high temperature and high pressure gas, enter indoor heat exchanger 2(and be condenser at this moment), the condensation liquefaction heat release becomes liquid, simultaneously room air is heated, thereby reach the purpose that improves indoor temperature.Liquid refrigerant is through capillary 10 and filter 11 expenditure and pressures, and inlet chamber external heat exchanger 8(is evaporimeter at this moment), evaporation gasification heat absorption becomes gas, simultaneously the heat (it is colder that outdoor air becomes) of suction chamber outer air.The cold-producing medium that becomes gas enters the next circulation of compressor 14 beginnings once more.
When winter, outside air temperature was low (as being lower than-5 ℃), because environment temperature and air conditioner heat-production operating mode differ bigger, the heat that the air-conditioner that designs according to standard condition can provide is far below the heat of standard condition and because lower environment temperature, the evaporating temperature of air-conditioner refrigerating system is very low, compressor is worked under high compression ratio, must cause volumetric efficiency, indicated efficiency to descend, the air-conditioner operational efficiency is low, heating effect is very poor.
In order to improve the result of use of detachable air conditioner under low temperature environment, normally on the indoor heat exchanger 2 of indoor set 1, electric heating device 3 is set.During the air conditioner heat-production operation, electric heating device 3 is worked simultaneously, to improve the heating effect of air-conditioner.But this method is when air conditioner heat-production moves, because outdoor environment temperature is lower, outdoor heat exchanger 8 heat exchange are insufficient, evaporating pressure is very low, and compressor 14 moves under high compression ratio, air-conditioner energy heterodyne, and can not avoid the defrosting operation of outdoor heat exchanger 8, thereby cause waste of electric energy.
Summary of the invention
The utility model provides a kind of electricity to assist heating air conditioner at the problems referred to above, and the compression ratio when this air-conditioner has reduced compressor operating has improved the volumetric efficiency and the indicated efficiency of system, makes the efficiency of air-conditioner get a promotion.
According to the technical solution of the utility model: a kind of electricity is assisted heating air conditioner, comprises indoor set and off-premises station; Be provided with indoor heat exchanger and indoor fan in the indoor set; Be provided with outdoor heat exchanger, outdoor fan and compressor in the off-premises station; The liquid in-out end of indoor heat exchanger is connected with the liquid in-out end of outdoor heat exchanger by fluid pipeline, and the gas in-out end of outdoor heat exchanger is connected with the gas in-out end of indoor heat exchanger by gas pipeline; Fluid pipeline is provided with capillary, and gas pipeline is provided with compressor; Described outdoor heat exchanger is provided with electric heating device.
The electrothermal tube of described electric heating device is an electrothermal tube, and with the outdoor heat exchanger close installation together.
Described fluid pipeline is provided with filter, and described filter bits is between described capillary and described outdoor heat exchanger.
Described fluid pipeline is provided with two-port valve, and described two-port valve is between described capillary and described indoor heat exchanger.
Described gas pipeline is provided with four-way change-over valve, and described four-way change-over valve is between described compressor and described indoor heat exchanger.
Described gas pipeline is provided with triple valve, and described triple valve is between described four-way change-over valve and described indoor heat exchanger.
Technique effect of the present utility model is: the utility model is with the electric heating device in the indoor set of the prior art, change in the off-premises station, during the air conditioner heat-production operation, electric heating device work in the off-premises station, outdoor heat exchanger is carried out heat supplement, improve the evaporating pressure of outdoor heat exchanger inner refrigerant, reduce the compression ratio of compressor operating, and in time outdoor heat exchanger is carried out defrosting operation, saves energy.
