When refrigerant flows to the 6th valve port n by the 5th valve port m, direction as denoted by the arrow a in figure 2, refrigerant enters in chamber 1631 by the 5th valve port m, enter in the first paragraph 1642 of passage 1641 by the first end of the passage 1641 of spool 164 again, under the promotion of refrigerant, movable part 165 moves along the direction shown in arrow A in second segment 1643, movable part 165 opens intercommunicating pore 1644, after refrigerant enters into second segment 1643 by first paragraph 1642, enter in chamber 1631 by intercommunicating pore 1644, now one-way throttle valve 7 plays tube connector, namely the pressure at passage 1641 two ends is substantially equal, when refrigerant flows to the 5th valve port m by the 6th valve port n, direction as designated by arrows b in fig, refrigerant enters in chamber 1631 by the 6th valve port n, enter in the second segment 1643 of passage 1641 by the second end of the passage 1641 of spool 164 again, under the promotion of refrigerant, movable part 165 moves along the direction shown in arrow B in second segment 1643, movable part 165 closes intercommunicating pore 1644, after refrigerant enters into second segment 1643 in chamber 1631, first paragraph 1642 is entered into by throttling passage 1651, being flowed out by the first end of passage 1641 enters in chamber 1631 again, because the cross-sectional area of throttling passage 1651 is much smaller than the cross-sectional area of second segment 1643, the pressure difference at passage 1641 two ends is larger, now one-way throttle valve 7 throttling actions.
Below with reference to Fig. 1, the course of work according to the air-conditioner 100 of the utility model embodiment is described.
When air-conditioner 100 is in refrigeration mode, the first port c of commutation assembly 2 is communicated with the second port d and the 3rd port e is communicated with the 4th port f.As shown in the solid arrow in Fig. 1, the refrigerant of discharging from the exhaust outlet a of compressor 1 carries out condensation by the first port c and the second port d inflow outdoor heat exchanger 3, the refrigerant that heat exchanger 3 is discharged outdoor enters into one-way throttle valve 7 by the 5th valve port m, the effect of tube connector is played in the now complete conducting of one-way throttle valve 7, the refrigerant flowed out from the 6th valve port n enters into check valve 5 by the first valve port g, because check valve 5 is ending from the first valve port g to the direction of the 4th valve port j, therefore refrigerant is flow in radiating subassembly 61 by the first valve port g and the second valve port h and dispels the heat to electric control element 60, the refrigerant flowed out from radiating subassembly 61 to flow into restricting element 8 through the 3rd valve port i and the 4th valve port j and carries out reducing pressure by regulating flow, the refrigerant of discharging from restricting element 8 is drained into indoor heat exchanger 4 to freeze to indoor environment, the refrigerant that heat exchanger 4 is discharged indoor passes through the 3rd port e, 4th port f and gas returning port b is expelled back into compressor 1, complete kind of refrigeration cycle.
When air-conditioner 100 is in refrigeration mode, because the temperature of the refrigerant of heat exchanger 3 discharge is outdoor a little more than environment temperature, therefore when temperature flows through radiating subassembly 61 a little more than the refrigerant of environment temperature, can dispel the heat to electric control element 60, effectively can also prevent the generation of condensed water simultaneously.
When air-conditioner 100 is in heating mode, the first port c of commutation assembly 2 is communicated with the 3rd port e and the second port d is communicated with the 4th port f.As shown in the dotted arrow in Fig. 1, the refrigerant of discharging from the exhaust outlet a of compressor 1 is drained into indoor heat exchanger 4 by the first port c and the 3rd port e and carries out condensation, the refrigerant that heat exchanger 4 is discharged indoor is drained in restricting element 8 and carries out reducing pressure by regulating flow, the refrigerant of discharging from restricting element 8 enters into check valve 5 from the 4th valve port j, the refrigerant major part entered from the 4th valve port j is discharged by the first valve port g, the refrigerant of discharging from the first valve port g enters into one-way throttle valve 7 by the 6th valve port n, due to one-way throttle valve 7 from the 6th valve port n to the circulating direction of the 5th valve port m be throttle part, therefore refrigerant carries out reducing pressure by regulating flow in one-way throttle valve 7, enter into outdoor heat exchanger 3 from the refrigerant of one-way throttle valve 7 discharge to evaporate, the refrigerant that heat exchanger 3 is discharged outdoor passes through the second port d, 4th port f and gas returning port b is expelled back in compressor 1, complete and heat circulation.
When air-conditioner 100 is in heating mode, outdoor environment temperature is lower, now heat in circulation only have little refrigerant or without refrigerant through radiating subassembly 61, what prevent low temperature refrigerant from the temperature of electric control element 60 being fallen is too low, can ensure the reliability of electric control element 60 during air-conditioner 100 heating operation.
According to the air-conditioner 100 of the utility model embodiment, by being provided with one-way throttle valve 7, check valve 5 and radiating subassembly 61, when refrigeration mode, close or a little more than environment temperature the refrigerant of temperature can be made to flow through radiating subassembly 61 to dispel the heat to electric control element 60.Effectively (even if when environment temperature is higher) can be dispelled the heat to electric control element 60 thus when not reducing the operating frequency of compressor 1, thus the refrigeration of air-conditioner 100 in the higher situation of environment temperature can be guaranteed, improve user's comfort.
And, due to flow into radiating subassembly 61 refrigerant temperature close to or a little more than environment temperature, therefore can avoid on electric control element 60, produce condensation water and the temperature of electric control element 60 is fallen too low, thus reliability and the security of electric control element 60 can be improved.When heating mode, the refrigerant major part of discharging from restricting element 8 is drained into outdoor heat exchanger 3 by check valve 5, only have sub-fraction low temperature refrigerant or without refrigerant, electric control element 60 dispelled the heat, can prevent condensed water from producing, ensure the reliability of electric control element 60 during air-conditioner 100 heating operation.
