For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
As Figure 1-Figure 5, the invention provides a kind of heating and air conditioner, the heating and air conditioner can both be heated
Also can be freezed.As illustrated, the heating and air conditioner include can discharging refrigerant compressor 3, indoor heat exchanger 1, room
External heat exchanger 2, and can be by the reversing piece 4 of commutate switching heating and air conditioner refrigeration or heating state, in above-mentioned, interior is changed
The concrete structure of hot device 1, outdoor heat exchanger 2 and compressor 3 is same as the prior art, the commutation and then realization of reversing piece 4
Refrigeration is also prior art with heating, is not repeated herein.The reversing piece 4 can be four-way valve, or four head and the tail phases
The pipeline connect.
As shown in figure 1, power component 5 is provided with outdoor heat exchanger 2 described in the heating and air conditioner of the present invention, it is described
Power component 5 is arranged in series the one-way throttle unit 6 of refrigerant flow in controllable power component 5, the unidirectional section
Stream unit 6 includes half-duplex channel and throttling passage, and the flow direction of the half-duplex channel is from the outdoor heat exchanger 2 to the room
Interior heat exchanger 1 flows into.
It should be noted that power component 5 described above includes the parts such as silicon bridge, diode, IPM, IGBT, it is with showing
There is air conditioner structure identical, will not be repeated here.
By the setting of above-mentioned one-way throttle unit 6, it is advantageous in that, switches refrigeration or heating shape in heating and air conditioner
During state, the flow of refrigerant in power component 5 is optionally controlled, and then realize the cooling to power component 5.
In order to further illustrate the technique effect of above-mentioned technical proposal, illustrated with reference to referring also to Fig. 6-Fig. 7.
As shown in fig. 6, it is heating and air conditioner of the present invention and the prior art (technical side i.e. mentioned in background technology
Case) under heating state, the cooling-down effect of each part in power component.Found by the contrast of the temperature, work(in the present invention
Each part of rate component has preferable cooling-down effect compared to prior art.
Simultaneously as shown in fig. 7, by the heating and air conditioner of the present invention and common product, prior art (i.e. in background technology
Involved technical scheme) contrast, it is possible to find the temperature change of power component of the present invention is more steady during defrosting, has
The life-span and the reliability that extend power component of effect.
Meanwhile it is as shown in table 1 below, table 1 is carried out for the present invention under heating state to heating each measuring point temperature of full warm area
Test measurement, it can be seen that by table 1, in this condition, disengaging radiator temperature is above outdoor environment dew-point temperature, and difference
It is larger, therefore condensation will not be produced on radiator line and power component.
To heating complete each measuring point temperature of warm area under the heating state of table 1
In addition, above-mentioned one-way throttle unit 6 can be that the one-way throttle unit 6 is one-way throttle valve 61 shown in Fig. 3.

There is capillary 8.As shown in fig. 6, it is parallel with the branch road that the one-way throttle unit 6 and the power component 5 form unidirectional
Part 9, the circulating direction of the unidirectional part 9 is to be flowed to from the outdoor heat exchanger 2 to the indoor heat exchanger 1.Preferably, it is described
Unidirectional part 9 is chosen as check valve.
It is complete because needing when heating and air conditioner runs refrigeration mode by the setting of capillary 8 or unidirectional part 9 in above-mentioned
Portion's opening one-way throttle 6 choke valves of unit are fully open, and the refrigerant flow for flowing through power component 5 may be excessive, and sets
Capillary 8 or unidirectional part 9 are put, advantageously reduces the refrigerant flow for flowing through power component 5.Meanwhile in the two schemes, it is excellent
Capillary 8 is selected, by the setting of capillary 8, the regulation such as length that can be by adjusting capillary flows through the refrigeration of power component 5
Agent flux, it is more convenient.
In the heating and air conditioner of the present invention, further comprise throttling unit 7, the throttling unit 7 is electronic expansion
One of valve or capillary pipeline are planted.
In addition, according to the above-mentioned heating and air conditioner of the present invention, present invention also offers a kind of control of heating and air conditioner
Method processed, the control method are that the throttling passage and half-duplex channel of one-way throttle unit are controlled when heating and air conditioner is freezed
It is fully open；When heating and air conditioner heats, the flow in the throttling passage in one-way throttle unit is controlled, is flowed into controlling
The flow of refrigerant into power component, and then cooling power component.
It should be noted that it is only disclosed in heating and refrigeration to the control method of heating and air conditioner in the present invention
When control to one-way throttle unit, and to the conventional other control methods of heating and air conditioner, such as to reversing piece circulating direction
Control etc., because it is above-mentioned be conventional design of the prior art, it is not described in detail herein.
