The connecting line of inner evaporator and motor compressor is provided with check valve.
The motor compressor porch is provided with gas-liquid separator.
The beneficial effect that the present invention has:
The present invention is by increasing parts such as internal condensation device and external boiler, heating power expansion valve, magnetic valve, utilize the heat and the external boiler of the generating set waste gas on the electric automobile to carry out heat exchange, efficiently solve heat pump type air conditioning system at low temperature, as-20 ℃ of problems that can't heat, realized that the comprehensive air-conditioning of electric automobile air-conditioning is regulated.By flexibly, suitably controlling the flow direction of cold-producing medium and the valve opening of expansion valve, can realize electric automobile heating at low temperatures, defrost function.
The present invention can conveniently heat by pattern control magnetic valve and refrigeration mode between switching, the part pipeline is the common pall of two kinds of patterns, thereby saved pipeline, dwindled air-conditioning system volume, alleviated the gross weight of electric automobile, thereby saved the energy resource consumption of electric automobile.
Description of drawings
Fig. 1 is refrigerant flowpath schematic diagram under the heating mode of the present invention;
Fig. 2 is refrigerant flowpath schematic diagram under the refrigeration mode of the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, the outlet of motor compressor 1 connects first pattern control magnetic valve 6, the outlet that heats of first pattern control magnetic valve 6 connects internal condensation device 2, the outlet of internal condensation device connects external boiler 3, and internal condensation device 2 is provided with heating power expansion valve 7 and check valve 11 with the connecting line of external boiler 3.External boiler can be carried out heat exchange with the waste gas of automobile generating unit, and the outlet that heats that external boiler connects second pattern control magnetic valve, 8, the second patterns control magnetic valve 8 connects motor compressor 1, and the motor compressor porch is provided with gas-liquid separator 10.
The refrigeration outlet of first pattern control magnetic valve 6 connects external condensation device 4, and connecting line is provided with check valve 12.The refrigeration outlet that the external condensation device connects second pattern control magnetic valve, 8, the second patterns control magnetic valve 8 connects inner evaporator 5, and heating power expansion valve 9 on the connecting line.The outlet of inner evaporator connects motor compressor 1, and connecting line is provided with check valve 13.
As shown in Figure 1, when air-conditioning system is in heating mode, the refrigeration port closing is opened in the outlet that heats of first pattern control magnetic valve 6 and second pattern control magnetic valve 8.Refrigerant R134a becomes the gas of HTHP through the compression of motor compressor 1, this gas enters internal condensation device 2 by the outlet that heats of first pattern control magnetic valve 6, the gas of HTHP becomes the liquid of HTHP at the internal condensation device through heat radiation, thereby has realized that the air themperature in the compartment raises.
Behind the liquid process heating power expansion valve 7 and check valve 11 step-downs of HTHP, medium becomes the liquid of low-temp low-pressure, the liquid of low-temp low-pressure externally evaporates in the evaporimeter 3, the cold-producing medium in the external boiler 3 and the high-temp waste gas of generating set carry out heat exchange at this moment, flow out external boiler, the outlet that heats of controlling magnetic valve 8 through second pattern enters gas-liquid separator 10, returns motor compressor 1, that goes round and begins again like this goes on, and realizes heat-production functions.The effect of gas-liquid separator 10 is devices of realizing gas-liquid separation, and the medium that compressor is got back in assurance is a pure gas, avoids damaging compressor.
As shown in Figure 2, when air-conditioning system is in refrigeration mode, the refrigeration outlet of first pattern control magnetic valve 6 and second pattern control magnetic valve 8 is opened, heat port closing.Refrigerant R134a becomes the gas of HTHP through the compression of motor compressor 1, this gas enters external condensation device 4 by the refrigeration outlet of first pattern control magnetic valve 6, the gas of HTHP externally condenser because the reduction of pressure and temp, cold-producing medium is liquid by condensation of gas and emits a large amount of heat, liquid arrives heating power expansion valve 9 by the refrigeration outlet of second pattern control magnetic valve 8, make through behind the heating power expansion valve, it is big that volume becomes, pressure and temperature sharply descends, cold-producing medium becomes the liquid of low-temp low-pressure, and the liquid of low-temp low-pressure evaporates in inner evaporator 5.Because this moment, the cold-producing medium boiling point was far below temperature in the evaporimeter, so refrigerant liquid flashes to gas, heat in evaporation process around a large amount of the absorption, thereby the temperature in the realization automobile bodies reduces, the refrigerant vapour of low-temp low-pressure is got back to compressor through gas-liquid separator 10, what said process went round and began again goes on, and realizes refrigerating function.
