Description
Technical field
The present invention relates to the electric vehicle engineering field, particularly a kind of electric automobile air-conditioning system.
Background technology
Along with the fast development of electric automobile, electric automobile air conditioner has also welcome unprecedented opportunity to develop.Below with reference to accompanying drawing, electric automobile air-conditioning system of the prior art is made introduction.
Please refer to Fig. 1, Fig. 1 is the principle schematic of a kind of electric automobile air-conditioning system in prior art.
As shown in Figure 1, the electric automobile air-conditioning system in the prior art comprise compressor 1 '; As shown in white arrow in Fig. 1, cold-producing medium is by compressor 1 ' outflow, and through cross valve 5 ' outflow left, enter in the 3rd heat exchanger 2 ' 3 with evaporator function through having condenser function First Heat Exchanger 2 ' 1, the second stop valve 6 ' 2, the second expansion valve 3 ' 2 this moment, then flowed out by the 3rd heat exchanger 2 ' 3, through gas-liquid separator 8 ' flow back to compressor 1 ' in, complete a closed circuit, this closed circuit can be defined as the first loop, and this first loop is used for realizing the refrigeration in summer.
In addition, as shown in black arrow in Fig. 1, cold-producing medium is by compressor 1 ' outflow, and through cross valve 5 ' outflow to the right, enter in the second heat exchanger 2 ' 2 with condenser function, then flowed out by this second heat exchanger 2 ' 2, through have the first expansion valve 3 ' 1, this moment First Heat Exchanger 2 ' 1, the first stop valve 6 ' 1 and the gas-liquid separator 8 of evaporator function ' flow back to compressor 1 ' in, complete a closed circuit, this closed circuit can be defined as second servo loop, and this first loop is used for realizing winter heating.
As shown in Figure 1, the 3rd heat exchanger 2 ' 3 and the second heat exchanger 2 ' 2 be located at the evaporation assembly casing 4 of air-conditioning system ' inside, and the 3rd heat exchanger 2 ' 3 be located at the second heat exchanger 2 ' 2 windward to a side, this evaporation assembly casing 4 ' inside also be provided with circulating fan 4 ' 1, under the effect of this blower fan, realize the rapid flow of circulated air.In addition, First Heat Exchanger 2 ' 1 is located at the outside in compartment, by with extraneous air generation heat exchange, realize its vaporization function or condensation function.Moreover, as shown in Figure 1, compressor 1 ' also be connected with frequency converter 7 '.
When temperature is low, such as in the winter time the time, as shown in Figure 1, and cross valve 5 ' circulation to the right, cold-producing medium flows along above-mentioned second servo loop, heats, and makes interior keep higher comfort temperature.At this moment, if being carried out defrosting-defogging, processes interior, need to switch cross valve 5 ' the flow direction, make cross valve 5 ' circulation left (stop circulating to the right, that is stop the compartment being heated), thereby cold-producing medium is along above-mentioned the first loop flow, the 3rd heat exchanger 2 ' 3 refrigeration, make the airborne steam of interior condense, process thereby carry out defrosting-defogging.Defrosting-defogging is after a period of time, then makes cross valve 5 ' commutation, makes it recover circulation to the right, thereby cold-producing medium flows along second servo loop again, thereby continues the compartment is heated.After heating a period of time, when interior has frost mist again, then repeat said process.
From the above, within a period of time of carrying out defrosting-defogging, cross valve 5 ' circulation left, and stop circulating to the right, the 3rd heat exchanger 2 ' 3 of above-mentioned air-conditioning system freezes and defrosting-defogging, and the second heat exchanger 2 ' 2 stops heating, thereby in defrosting-defogging, also reduce the temperature of interior, thereby made the comfort of interior reduce.In addition, this defrosting-defogging operation can not be carried out the long period continuously, otherwise can make the temperature of interior too low, so that subzero, obviously be insupportable this winter in cold; Because the defrosting-defogging operation can not be carried out the long period continuously, thereby its defrosting-defogging effect is also also bad.
In addition, above-mentioned electric automobile air-conditioning system also can't carry out the critical component of electric automobile cooling, such as battery and motor frequency conversion device etc.; Especially in summer, too high temperature can make the performance of these critical components greatly reduce, thereby significantly reduces the flying power of electric automobile.
