Wherein, electric water pump 7 can also can be split type electric water pump for the integral electric water pump, can be the adjustable speed water pump, also can be the constant speed water pump, can be that centrifugal pump also can be a membrane pump.Present embodiment preferably adopts the integral electric water pump.
Motor driven compressor 1 can be a closed-type electrically-driven compressor, it also can be semi-enclosed motor driven compressor, it can be the vortex type motor driven compressor, also can be to become the displacement motor driven compressor, it can be integrated electric compressor, also can be split type motor driven compressor, present embodiment preferably adopts the integrated electric compressor of enclosed vortex type.
Below describe mode of operation of the present utility model in detail:
When summer condition; as shown in Figure 2; loop direction shown in the filled arrows among the figure; air conditioner refrigerating on-cycle working process is: motor driven compressor 1 is compressed into the gaseous refrigerant of low-temp low-pressure the gaseous refrigerant of High Temperature High Pressure; directly enter four-way change-over valve 3; the gaseous refrigerant of High Temperature High Pressure is by four-way change-over valve 3 back inlet chamber external heat exchangers 6; the gaseous refrigerant of High Temperature High Pressure is by outdoor heat exchanger 6 heat radiations; be condensed into the liquid refrigerant of High Temperature High Pressure; the liquid refrigerant of High Temperature High Pressure is flowed through behind the throttle unit 5; become the liquid refrigerant of low-temp low-pressure through the throttling step-down; enter the heat in the indoor heat exchanger 4 back absorption car room airs; the liquid refrigerant of low-temp low-pressure undergoes phase transition rapidly; thereby flash to the gaseous refrigerant of low-temp low-pressure, at this moment, the gaseous refrigerant of low-temp low-pressure is by in the gas-liquid separator 2; gas-liquid separator 2 is to prevent motor driven compressor 1 by the guard block of liquid hammer, and what can guarantee to enter motor driven compressor 1 is gaseous refrigerant entirely.After the gaseous refrigerant of low-temp low-pressure comes out from gas-liquid separator 2, be compressed into the gaseous refrigerant of High Temperature High Pressure once more by motor driven compressor 1, so periodical duty.It is indoor to be admitted to car through the air of indoor heat exchanger 4 cooling, reduces the indoor temperature of car, and comfortable environment by bus is provided.
When summer condition, when automobile needed a/c system A to produce refrigeration, each heat dissipation element also needed heat radiation, with the requirement of satisfying normal vehicle operation and the requirement of occupant's traveling comfort.In process of refrigerastion, the heat of a/c system A is taken away by outdoor heat exchanger 6, because outdoor heat exchanger 6 adopts the ability of swimming heat exchanger, so heat-sinking capability is much larger than air cooling heat exchanger.Can reduce the power consumption of a/c system A motor driven compressor 1 like this, thereby increase the refrigerating capacity of a/c system A.Meanwhile, as shown in Figure 2, loop direction shown in the filled arrows among the figure, the working process of cooling system B refrigerating cycle is: refrigerant fluid is under the drive of electric water pump 7, with first heat element 8, second heat element 9, the heat that heat that the 3rd heat element 10 produces and outdoor heat exchanger 6 produce is discharged in the atmosphere by radiator 12, this moment is by controlling the direction of opening of two electric control valves 11, refrigerant fluid can be dispelled the heat by radiator 12 smoothly, refrigerant fluid after the heat radiation is got back in the electric water pump 7 once more, under the drive of electric water pump 7, circulate next time, after repeatedly circulating, can the actv. cooling heating element.
Under this operating mode, because the heat that a/c system A produces dispels the heat by outdoor heat exchanger 6, outdoor heat exchanger 6 has participated in the circulation among the cooling system B simultaneously, because under the drive of the electric water pump 7 in cooling system B, in system, circulate very frequent of refrigerant fluid, simultaneously it can take the heat of outdoor heat exchanger 6 to radiator 12 places and dispels the heat, and can make a/c system A refrigeration faster, thereby increase the refrigerating capacity of a/c system A.
In the winter time during operating mode, because a/c system A is owing to be heat pump type air conditioning system, so a/c system A will heat, the refrigerant trend of a/c system A is shown in Fig. 3 hollow core arrow, air-conditioning heats the on-cycle working process: promptly: motor driven compressor 1 is compressed into refrigerant the gaseous refrigerant of High Temperature High Pressure, enter indoor heat exchanger 4 by four-way change-over valve 3, release heat, the gaseous refrigerant of High Temperature High Pressure becomes the gaseous refrigerant of cryogenic high pressure, pass through throttle unit 5 then, the gaseous refrigerant of cryogenic high pressure has become the liquid refrigerant of low-temp low-pressure, passes through outdoor heat exchanger 6 then, absorbs heat from refrigerant fluid on every side, thereby become the refrigerant gas of low-temp low-pressure, once more get back to compressor 1 through four-way change-over valve 3 and gas-liquid separator 2 this moment, goes round and begins again, and circulation is gone down.
Meanwhile, shown in Fig. 3 hollow arrow, the cooling system B working process under the operating mode in the winter time is: under the drive of electric water pump 7, refrigerant fluid is respectively through first heat element 8, second heat element 9, the 3rd heat element 10, refrigerant fluid absorbs inlet chamber external heat exchanger 6 behind the heat that these heat elements distribute, heat in the refrigerant fluid is absorbed by the refrigerant among the a/c system A, after the refrigerant fluid that has been absorbed heat comes out from outdoor heat exchanger 6, open direction by control electric control valve 11, make refrigerant fluid directly not get back in the electric water pump 7 by radiator 12, so circulation is gone down.
Because in the winter time during operating mode, outdoor heat exchanger 6 is as the device that absorbs heat, so absorbed by outdoor heat exchanger 6 heat that first heat element 8, second heat element 9, the 3rd heat element 10 among the cooling system B produce this moment by a/c system A, thereby increase the heat of a/c system A, and can also prevent that frosting influences heating effect to outdoor heat exchanger 6 owing to absorbing heat from surrounding environment.
The transfer of heat that when this scheme advantage is in the winter time first heat element 8, second heat element 9, the 3rd heat element 10 is produced heats in the circulation to a/c system A, makes heat obtain utilization, and outdoor heat exchanger 6 frostings when having prevented that air-conditioning from heating.When summer condition, the heat among the a/c system A is transferred among the cooling system B by outdoor heat exchanger 6, and heat is dispersed in the atmosphere, thereby reduce the consumption of current of air-conditioning compressor by the radiator among the cooling system B 12, increase refrigerating capacity.
The specific embodiment of the above is a better embodiment of the present utility model; be not to limit concrete practical range of the present utility model with this; the equivalence that all shapes according to the utility model, structure are done changes, and all is included in the protection domain of the present utility model as the simple replacement to devices such as motor driven compressor, electric water pump, radiator, heat exchangers.
