Embodiment one.
A kind of method for improving air conditioner heat pump system operational efficiency, it is comprised the following steps：
First, a condensation water collection 8 is increased in the bottom of evaporator 5, collection obtains temperature between 10 DEG C~15 DEG C
Cryogenic condensation water；
Secondly, the cryogenic condensation water for collection being obtained is delivered coal in a condensation water heat exchanger 9 by pipeline；
3rd, a reservoir 7 is increased in water heat exchanger 9 is condensed, the working medium from condenser out is introduced into storage
The temperature of the working medium for carrying out heat exchange to be lowered into expansion valve 6 with the condensed water of condensation water heat exchanger 9 in liquid device, so that
The temperature of the working medium of the entrance point of evaporator 5 is reduced, improve working medium crosses cold, reduce working medium and enter electric heat pump compressor 3
Temperature, so as to improve the refrigerating capacity and COP values of electric heat pump compressor.As shown in figure 1, the working medium of the exhaust ports of compressor 3
By the liquid as middle temperature high pressure, its temperature T after condenser 1340 DEG C of ＞, and the temperature T of condensed water0About at 10 DEG C~15 DEG C
Between, working medium carries out heat exchange when the reservoir 7 in being immersed in condensed water is flowed through with condensed water, enter expansion valve 6 it
Before, T can be down to4', about 30~35 DEG C, and T3' ＜ T3, therefore by after expansion valve 6 enter evaporator 5 before, there is provided
Working medium supercooling temperature T in the system of present invention condensation water heat exchanger 94' less than the working medium being not provided with the system of the device
Supercooling temperature T4, therefore condensation water heat exchanger 9 of the invention improves the cold excessively of working medium, is favorably improved the refrigerating capacity of system
With COP values.
As can be seen here, the present invention enters the tank for being equipped with reservoir by pipeline communication after the condensation water collection in evaporation tank
Row heat exchange, reducing temperature twice treatment is carried out to the working medium for not flowing through expansion valve using cryogenic condensation water, and (once cooling is by condensation
Blower fan 2 is carried out), working medium degree of supercooling is improved to reach, cooling system amount and COP are improved, it is finally reached raising automobile course continuation mileage
Purpose.
Embodiment two.
As shown in Figure 1-2.
A kind of device for improving air conditioner heat pump system operational efficiency, it includes electric heat pump compressor 3, condenser 1, liquid storage
Device 7, expansion valve 6 and evaporator 5, the input of the high pressure side joint condenser 1 of electric heat pump compressor 3, the outlet side of condenser 1
