--- in summer, the cooling of electrokinetic cell needs to be cooled down using vapour compression refrigeration system refrigerating operaton.Its work It is as process：Working medium pump 1 draws working medium from reservoir 12 and enters battery heat exchanger 4 by electrical auxiliary heater 5, in battery Absorbed heat in heat exchanger 4 and cool down electrokinetic cell, electrokinetic cell is kept suitable temperature, working medium is then heated up, Ran Houjin Enter the IIIth triple valve 6；Now, the IIIth triple valve a port 6a, the IIIth triple valve c port 6c are turned on, the IIIth triple valve b port 6b Obstructed, the working medium after heating enters First Heat Exchanger 8 by the IIIth triple valve a port 6a, the IIIth triple valve c port 6c.Now Independent vapour compression refrigeration system is in refrigerating state, and the refrigerant vapour for the HTHP discharged from compressor 13 enters 3rd heat exchanger 15, refrigerant vapour is condensed into refrigerant liquid by surrounding air in the 3rd heat exchanger 15, subsequently into section The decrease temperature and pressure of mechanism 16 is flowed, forms the refrigerant of low temperature（Vapour-liquid）Two-phase state simultaneously enters First Heat Exchanger 8, by working medium therein Cool, refrigerant heat absorption is evaporated to refrigerant vapour, returns to compressor 13 through four-way valve 14, completes a kind of refrigeration cycle. Now, the vapour compression refrigeration system had both completed the air conditioner refrigerating of electric automobile, completed the condensation to working medium again.Institute State the working medium being condensed and enter the Vth triple valve 10, now, the Vth triple valve c port 10c, the Vth triple valve b port 10b are led Logical, the Vth triple valve a port 10a are obstructed, and working medium is returned by the Vth triple valve c port 10c, the Vth triple valve b port 10b and stored up Liquid device 12, complete the down cycles once using extraneous low-temperature receiver to electrokinetic cell.

--- in winter, electrokinetic cell needs to be heated using the heat pump of vapour compression refrigeration system, if necessary may be used Electrical auxiliary heater 5 is opened further to be heated.Its course of work is：Working medium pump 1 is drawn working medium and led to from reservoir 12 Electrical auxiliary heater 5 is crossed, electrical auxiliary heater 5 can be now opened if necessary and working medium is further heated, make working medium temperature Degree further rise, is heated subsequently into battery heat exchanger 4 to electrokinetic cell, ensures that electrokinetic cell has suitable temperature Degree.At this moment the temperature of working medium is lowered；Reduce the working medium after temperature and enter the IIIth triple valve 6, now, the IIIth triple valve a ports 6a, the IIIth triple valve c port 6c are turned on, and the IIIth triple valve b port 6b are obstructed, and working medium passes through the IIIth triple valve a port 6a, the IIIth Triple valve c port 6c enter First Heat Exchanger 8.Now, independent vapour compression refrigeration system is in heat pump heating state, from The refrigerant vapour for the HTHP discharged in compressor 13 enters in First Heat Exchanger 8, will enter the work of First Heat Exchanger 8 Matter heat temperature raising, and refrigerant vapour is then condensed into after refrigerant liquid into throttle mechanism 16 and continues decompression cooling, is formed The refrigerant two-phase state of low temperature；The refrigerant of two-phase state enters the 3rd heat exchanger 15, and the heat drawn in surrounding air steams Send out as refrigerant vapour, then compressor 13 is returned by four-way valve 14, complete the heating of primary steam compression-type refrigerating system heat pump Circulation, realize the heat temperature raising to working medium.And the working medium being heated up then enters the Vth triple valve 10, now the Vth 3 Port valve c port 10c, the Vth triple valve b port 10b are turned on, and the Vth triple valve a port 10a are obstructed, and working medium passes through the Vth triple valve C ports 10c, the Vth triple valve b port 10b return to reservoir 12.Completion once utilizes independent vapour compression refrigeration system Heat pump to the heat cycles of electrokinetic cell.
