Detailed description of the invention
Structure and the use principle of pure electric automobile heat pump type air conditioning system this utility model provided below in conjunction with accompanying drawing are described in further details.
It is illustrated in figure 2 the structural representation of the pure electric automobile heat pump type air conditioning system that this utility model provides. Its structure includes: connected compressor controller 2 by set of cells 3, and this controller connects screw compressor 1; The air vent of compressor connects the entrance 121 of four-way change-over valve, and the air entry of compressor connects the outlet 151 of gas-liquid separator 15; Its excess-three mouth 123,122,124 of four-way change-over valve is connected with the outlet of car indoor heat exchanger 11, the outlet of car outdoor heat exchanger 4 and the entrance 152 of gas-liquid separator 15 respectively;Car external heat exchanger 4 is connected with the first exsiccator 5, and in car, heat exchanger 11 is connected with the second exsiccator 10; The first expansion valve the 7, first check valve 6 and the second check valve 9 second expansion valve 8 is connected respectively by three-way valve between above-mentioned two exsiccator; Being connected motor heat exchanging air duct 13 between motor 14 with car external heat exchanger 4, air channel is built-in with fan 16 and air channel controlling organization 17, it is possible to achieve motor waste heat is drawn into car external heat exchanger place; The temperature-sensitive bag 41,42 controlling first and second expansion valve it is respectively fixed with in the exit of above-mentioned car external heat exchanger and Che Nei heat exchanger.
Constituting in the structure of above-mentioned pure electric automobile heat pump type air conditioning system, screw compressor is electric scroll compressor, and car outdoor heat exchanger is preferably used parallel-flow heat exchanger, and car indoor heat exchanger is preferably used fin-tube type heat exchanger, and expansion valve adopts internal balance type list end valve.
Its operation principle is:
When system is in refrigeration mode as shown in Figure 2, cross valve 12 no power, the gaseous working medium of low-temp low-pressure becomes high pressure gaseous working medium after compressor 1 compresses, flow through cross valve 12 and arrive outdoor heat exchanger 4, the gaseous working medium of High Temperature High Pressure becomes the liquid of medium temperature and medium pressure after outdoor heat exchanger with outside air heat convection, flow through the first exsiccator 5 impurity screening and moisture, pass through after the first check valve 6 through the second expansion valve 8 reducing pressure by regulating flow, the temperature and pressure of working medium reduces further, become vaporific after after the second exsiccator dries 10 heat exchanger 11 in inlet chamber, working medium is evaporation endothermic in indoor heat exchanger 11, thus reducing the temperature that car is indoor, now working medium becomes the gas of low-temp low-pressure through indoor heat exchanger 11 outlet, eventually pass through four-way change-over valve 12, gas-liquid separator 15 enters in compressor 1, complete kind of refrigeration cycle.
When system is in heating mode as shown in Figure 3, cross valve 12 is energized, the flow direction of its working medium is as shown in Figure 4: the high pressure gaseous working medium that compressor 1 is discharged enters indoor heat exchanger 11 through cross valve 12, the heat carried is passed to the air that car is indoor by working medium, thus realizing the function of heating, then working medium is through the second exsiccator 10, second check valve 9, then pass through after the reducing pressure by regulating flow of the first expansion valve 7 through the first exsiccator 5 inlet chamber external heat exchanger 4, evaporation endothermic in outdoor heat exchanger 4, heat in environment is brought in system, last under the swabbing action of compressor 1, working medium returns in compressor through cross valve 12 and gas-liquid separator 15, complete to heat circulation.
Under above two pattern, the temperature-sensitive bag 41,42 being fixed on the exit of above-mentioned car external heat exchanger and Che Nei heat exchanger controls the size expansion of first and second expansion valve 7,8 respectively.
When system is in refrigeration mode, outdoor heat exchanger 4 is as condenser environment heat release towards periphery, cold wind is needed to make heat exchanger 4 cool down, now stir downwards connecting rod 132 to position shown in Fig. 4, first air port 134 is blocked by air channel barrier 131, and under fan effect, air carries out heat exchange from the second air port 135 inlet chamber external heat exchanger 4.
When system is in heating mode, time ambient temperature is relatively low, outdoor heat exchanger 4 is difficult to absorb heat from environment, cause that system heating efficiency declines, now stir downwards second connecting rod 133 to be blocked in the second air port 135, under fan effect, motor waste heat makes air themperature about improve from the first air port inlet chamber external heat exchanger 4, thus improve the heating efficiency of heat pump air conditioner.
