Wherein, subcooler 1.6 and electric expansion valve (pair) 1.7 are used to be carried out to frequency-variable module 1.5
Cooling, when crossing module 1.5 through frequency conversion by the condensed refrigerant of outdoor heat exchanger 1.3 (40 ° or so)
When certain cooling down can be carried out to it, but because the refrigerant of saturation state absorbs frequency-variable module
1.5 heat has certain evaporation, and now most of refrigerant continues to go ahead, and fraction refrigerant is by electricity
Sub- expansion valve (pair) 1.7 throttles, and most of refrigerant is subcooled in subcooler 1.6, so that
It is set to be changed into saturation state again；Air conditioner structure of the prior art is complicated, high cost.
Fig. 2 shows a kind of structural representation of air-conditioner of the embodiment of the present invention, as shown in Fig. 2
In some illustrative embodiments, the air-conditioner, including：
Compressor 1, outdoor heat exchanger 3 and the indoor heat exchanger 9 being sequentially connected, also including radiating branch road,
The first end of the radiating branch road is connected to the outdoor heat exchanger 9, and the second end is connected to the compressor
1 import, is provided with capillary 6 on the radiating branch road, the radiating branch road flows through the air-conditioner
Frequency-variable module 7, and carry out heat exchange with the frequency-variable module 7.
In some illustrative embodiments, it is provided with magnetic valve 5 on the radiating branch road.
In some illustrative embodiments, the air-conditioner also includes electric expansion valve 4, the electronics
Expansion valve 4 is arranged on the pipeline between the first end of the radiating branch road and the outdoor heat exchanger 3.
In some illustrative embodiments, the air-conditioner also includes gas-liquid separator 11, the gas
The outdoor heat exchanger 3 or the frequency-variable module 7 are flowed out on liquid/gas separator 11 and the radiating branch road
Pipeline is connected.
In some illustrative embodiments, the radiating branch road also includes metallic heat exchanging tube, the gold
Category heat exchanger tube is connected to the port of export of the capillary 6.
In some illustrative embodiments, the frequency-variable module 7 includes heat exchanger plates 12, the gold
Category heat exchanger tube is arranged on the heat exchanger plates 12.
In some illustrative embodiments, mounting groove 13, the gold are provided with the heat exchanger plates 12
Category heat exchanger tube is arranged in the mounting groove 13, such as shown in Fig. 3.
In some illustrative embodiments, the mounting groove 13 is coiled on the heat exchanger plates 12 and set
Put, the metallic heat exchanging tube is the coil pipe with the structure matching of the mounting groove 13.
In some illustrative embodiments, the metallic heat exchanging tube is copper refrigerant pipe.
In some illustrative embodiments, the metallic heat exchanging tube is arranged at the heat exchanger plates 12 and deviates from
The side of the mainboard of the frequency-variable module.
According to the refrigerant radiating schematic diagram of air-conditioner in Fig. 2, it is known that in process of refrigerastion, refrigerant
Main body is flowed to：1-four-way valve of compressor (d-c is connected) 2-outdoor heat exchanger, 3-electric expansion valve
4-liquid pipe stop valve 8-indoor heat exchanger, 9-tracheae stop valve, 10-four-way valve (e-s is connected) 2-
11-compressor of gas-liquid separator 1；
Wherein, compressor 1 and leads to the compressing refrigerant gas of low-temp low-pressure into the gas of HTHP
Cross four-way valve (d-c) 2 and enter the saturation liquid refrigerants that outdoor heat exchanger 3 is condensed into middle temperature high pressure, pass through
Electric expansion valve 4 (now refrigeration is standard-sized sheet, without throttling) is crossed, is divided into two parts；Wherein one
Point (main body) gets in heat exchanger 9 and is evaporated (now indoor temperature by liquid pipe stop valve 8
Reduce) it is changed into low-temp low-pressure gaseous coolant, by tracheae stop valve 10, four-way valve (s-c) 2 enters
Enter gas-liquid separator 11, come back to compressor 1.
When press long running time or high frequency run, the press of computer board detection drives frequency-variable module 7
Temperature is too high to need radiating and cooling, and now magnetic valve 5 is opened, and has the full of the middle temperature high pressure of sub-fraction
(state is liquid to gas by the reducing pressure by regulating flow of capillary 6 to be changed into the refrigerant of low-temp low-pressure with liquid refrigerants
The beginning of state transformation), now it is very easy to absorb heat and be evaporated be changed into gaseous state.Just frequency-variable module
7 temperature are high, are badly in need of radiating, and so the two meets, and each takes what he needs.Refrigerant is changed into the gaseous state of low-temp low-pressure
Into gas-liquid separator 11, the reduction of the temperature of frequency-variable module 7 meets unit normal operation.Here due to
It is that the direct absorption module heat of refrigerant completes evaporation, can be cold to control by adjusting the specification of capillary 6
The pressure drop of matchmaker.Such as：, at 5 °, the radiating effect of such frequency-variable module 7 can be very for control evaporating temperature
It is good.When the temperature of frequency-variable module 7 is dropped to normally, magnetic valve 5 is closed.
Additionally, in practical application, during capillary 6 is lowered the temperature to frequency-variable module 7, by
It is possible relatively low (9 ° or so) in the refrigerant temperature after throttling, it is aquatic that condensation is might have in some cases
Into so frequency-variable module 7 should consider the problem of condensed water in design.Frequency conversion mould typically now
It is all that, with the heat exchanger plates 12 (such as fin) of aluminum, can be slotted with lathe tool on aluminium sheet that block 7 radiates,
For placing refrigerant pipe, but groove 13 necessarily can not be penetrating, and the computer board of module can be fixed on aluminium sheet
Opposite side, so can be achieved with condensed water and separate that (structure of specific aluminium sheet can be with computer board
Shown in reference picture 2).
