Closed state.It needs to illustrate, when the first control valve 5 is electric expansion valve, in cooling mode, the first control valve 5
Aperture should be larger and so that the first control valve 5 plays reducing pressure by regulating flow or reducing pressure by regulating flow and acts on smaller, ensures from first
Control valve 5 flow out refrigerant and from outdoor heat exchanger 3 flow out refrigerant between the temperature difference it is smaller.
As shown in the solid arrow in Fig. 1, the refrigerant discharged from the exhaust outlet a of compressor 1 passes through first port c and second
Port d flows into outdoor heat exchanger 3 and is condensed, and the first list is entered from the refrigerant that outdoor heat exchanger 3 is discharged by the first valve port m
Into throttle valve 7, the first one-way throttle valve 7 is fully at this time plays the role of connecting tube.
When the second control valve 12 in the open state, from the second valve port n flow out refrigerant be divided into two parts, wherein one
Point refrigerant is flowed into from the 4th valve port j in the second one-way throttle valve 8 by the second refrigerant flow 10, and another part refrigerant passes through the
One control valve 5, which is flowed into radiating subassembly 61, radiates to electric control element 60, and the refrigerant flowed out from radiating subassembly 61 is from the 4th
Valve port j is flowed into the second one-way throttle valve 8.That is, two parts refrigerant converges in the second one-way throttle valve 8.When
When two control valves 12 are closed, the refrigerant flowed out from the second valve port n is all introduced into the first refrigerant flow 9, refrigerant
It is flowed into radiating subassembly 61 by the first control valve 5 and radiated to electric control element 60, the refrigerant flowed out from radiating subassembly 61
It is drained into the second one-way throttle valve 8.
Since the second one-way throttle valve 8 is throttle part on the circulating direction from the 4th valve port j to the 3rd valve port h, because
This refrigerant being flowed into the second one-way throttle valve 8 carries out reducing pressure by regulating flow in the second one-way throttle valve 8.
The refrigerant discharged from the second one-way throttle valve 8 is drained into indoor heat exchanger 4 to freeze to indoor environment, from
The refrigerant that indoor heat exchanger 4 is discharged is expelled back into compressor 1 by third port e, the 4th port f and gas returning port b, completes refrigeration and follows
Ring.

Temperature, therefore when the refrigerant that temperature is slightly above environment temperature flows through radiating subassembly 61, can radiate to electric control element 60,
The generation of condensed water can also be effectively prevented simultaneously.
When air conditioner 100 is in heating mode, the first port c of commutation component 2 is connected with third port e and second end
Mouth d and the 4th port f connections, the second control valve 12 are in opening state, and the first control valve 5 may be at closed state or beat
Open state.As shown in the dotted arrow in Fig. 1, the refrigerant discharged from the exhaust outlet a of compressor 1 passes through first port c and the 3rd
Port e is drained into indoor heat exchanger 4 and is condensed, and the refrigerant discharged from indoor heat exchanger 4 is drained into second from the 3rd valve port h
One-way throttle valve 8, since the second one-way throttle valve 8 is fully on the circulating direction from the 3rd valve port h to the 4th valve port j,
Therefore the second one-way throttle valve 8 plays the role of connecting tube.
