operation principle
Kind of refrigeration cycle: shown in composition graphs 2, when freezing, first closes defrosting magnetic valve 11, second check valve 13 and the 5th check valve 20.The specific works process of kind of refrigeration cycle is: compressor 1 consumes the gaseous refrigerant that the gaseous refrigerant of low-temp low-pressure is compressed into HTHP by certain electric energy, after the gaseous refrigerant of HTHP enters the first cross valve 2 from D pipe, enter car outdoor heat exchanger 3 from the C pipe of the first cross valve 2 to reject heat to the air of car outdoor, gaseous refrigerant undergoes phase transition and is condensed into liquid state.Liquid refrigerant flows through the first check valve 6 and the step-down cooling when the first expansion valve 5, after the cold-producing medium of the liquid state after cooling and a small amount of gaseous state enters the second cross valve 7 from D pipe, enter flash vessel 12 through device for drying and filtering 8, the 3rd expansion valve 9 and magnetic valve 10 successively from the C pipe of the second cross valve 7.Gas refrigerant in flash vessel 12 enters compressor 1 by the 4th check valve 19 via the tonifying Qi hole of compressor; In flash vessel 12, liquid refrigerant flows back to the second cross valve 7 from the E pipe of one-pipe 18, then enter through the second expansion valve 14 heat that first car indoor heat exchanger 4a absorbs room air, cold-producing medium undergoes phase transition and flashes to gaseous state, gaseous refrigerant leads to after E pipe enters the first cross valve 2 by pipeline again, flow back to from the S pipe of the first cross valve 2 and enter compressor 1, complete kind of refrigeration cycle, and then repeat above cyclic process, realize the object reducing car indoor temperature and improve comfortableness.
Heat circulation: shown in composition graphs 3, when heating, first the first check valve 6 is closed, then defrosting magnetic valve 11 is set as normally off, only just defrosting magnetic valve 11 is opened when needs defrost, close immediately after completing defrosting.First cross valve 2 and the second cross valve 7 are under the driving of corresponding micro servo motor, and the cold-producing medium flow direction is therein changed, and car indoor heat exchanger 4 becomes condenser, and car outdoor heat exchanger 3 becomes evaporimeter.The specific works process heating circulation is: compressor 1 consumes the gaseous refrigerant that the gaseous refrigerant of low-temp low-pressure is compressed into HTHP by certain electric energy, after the gaseous refrigerant of HTHP enters the first cross valve 2 from D pipe, the first car indoor heat exchanger 4a and the second car indoor heat exchanger 4b is entered from the E pipe of the first cross valve 2, reject heat in car room air, gaseous refrigerant undergoes phase transition and is condensed into liquid state, liquid refrigerant is successively through the 5th check valve 20 and the second check valve 13, and when flowing through the second expansion valve 14, cold-producing medium step-down is lowered the temperature, after entering the second cross valve 7 from S pipe afterwards, manage successively through device for drying and filtering 8 from the C of the second cross valve 7 again, 3rd expansion valve 9 and magnetic valve 10 enter flash vessel 12.Gas refrigerant in flash vessel 12 enters compressor 1 by the 4th check valve 19 via the tonifying Qi hole of compressor; After in flash vessel 12, liquid refrigerant flows back to the second cross valve 7 from the E pipe of one-pipe 18, D pipe again through the second cross valve 7 enters from the first expansion valve 5 heat that car outdoor heat exchanger 3 absorbs car outdoor air, liquid refrigerant undergoes phase transition and flashes to gaseous state, the gaseous refrigerant of low-temp low-pressure enters the first cross valve 2 from C pipe, compressor 1 is entered afterwards from the S pipe of the first cross valve 2, complete heating cycle, and then repeat above cyclic process, realize the object of falling-rising high indoor temperature and raising comfortableness.
The defrosting principle of this device: described car outdoor heat exchanger 3 is evaporimeter, in the winter time under operation of heat pump operating mode, there will be frost, frost layer can plug the spacing of the heat exchange fin of car outdoor heat exchanger 3, hinder the flowing that outdoor air skims over heat exchanger fin, thus the exchange heat affected between car outdoor heat exchanger 3 internal refrigeration storage agent and outdoor air, so when the outer frost layer of fin is agglomerated to certain thickness, heat pump circulating system must carry out defrosting operating condition operation.According to the shortest path circulation theory of fluid flowing, during Defrost operation operating mode, the blower fan of car outdoor heat exchanger 3 and car indoor heat exchanger 4 is out of service, defrosting electromagnetic opening, after the high-temperature gas that compressor 1 is discharged flows through defrosting electromagnetism, enter car outdoor heat exchanger 3, the frost layer of melting vehicle outdoor heat exchanger 3 fin, then entered into the suction muffler of compressor by the aspirating air pipe of compressor 1, until the fin frost layer of car outdoor heat exchanger 3 is all melted, Defrost operation pattern terminates, and heat pump cycle pattern starts.
