System, it is low also to cause the appearance of dew condensation phenomenon, so as to reach that one can cool down to frequency-variable module and avoid it from condensation occur
The purpose of phenomenon.
Shown in reference picture 1, in order to cause refrigerant more preferable to the radiating effect of frequency-variable module 13, make refrigerant transmission logical
The area that road is contacted with frequency-variable module 13 is bigger, optionally, and described heat dissipation region 17 is by first passage in above-described embodiment
Predetermined fraction bends to predetermined shape and formed, and its concrete shape is not limited in embodiments of the present invention.
On in real time, because when the frequency-variable module in the frequency-variable air conditioner outdoor machine provided above-described embodiment is cooled down,
When frequency-variable module is cooled to certain temperature by refrigerant, in order to avoid dew condensation phenomenon occurs in frequency-variable module, the second valve can be opened
And control the aperture of the first valve to reduce so as to reach the purpose for no longer making frequency-variable module cool, but rely solely on the first valve
Dredging of the door to the limitation and the second valve of refrigerant to refrigerant, sometimes because the effect of refrigerant is powerful or frequency-variable module environment
Temperature is higher to be led to not reach the purpose for no longer making frequency-variable module cool, so, shown in reference picture 2, another reality of the invention
Applying the structure of the design of frequency-variable air conditioner outdoor machine 1 of example offer also includes：The outlet of compressor 11 connects described by third channel
The 3rd valve 19 is provided with heat dissipation region 17, the third channel；The first valve 16 and the second valve 18 regulation not
Frequency-variable module temperature can be made not in the case of reduction, the 3rd valve 19 is opened so that the high temperature of the outlet of compressor 11 output is cold
Some refrigerant entered in heat dissipation region 17 and major loop of matchmaker is combined, so as to reach the mesh of the temperature of heat radiation region 17
, the temperature for also allowing for frequency-variable module 13 is raised.
It should be noted that specific four-way valve is referred to figure with compressor, indoor set, the annexation of outdoor heat exchanger
Shown in 1 and Fig. 2, its annexation is specially：The outlet of the first port a connections compressor 11 of four-way valve 12, four-way valve 12
Second port b connections outdoor heat exchanger 14 first end；Second end of indoor set 3 connects the 4th port d of four-way valve 12, four
The entrance of 3rd port c connections compressor 11 of port valve 12.
It is preferred that, in frequency-variable air conditioner outdoor machine provided in an embodiment of the present invention, in order to preferably control the flow of refrigerant,
First valve and the second valve are electric expansion valve.
It is preferred that, in frequency-variable air conditioner outdoor machine provided in an embodiment of the present invention, the 3rd valve is magnetic valve.
Shown in reference picture 3, the embodiment of the present invention also provides a kind of change for the frequency-variable air conditioner outdoor machine that above-described embodiment is provided
The cooling means of frequency module, including：
301st, when it is determined that the temperature of frequency-variable module is more than or equal to first threshold, the second valve is closed, and according to frequency conversion mould
The temperature of block increases the aperture of the first valve.
Specifically, now the aperture of the first valve is because the size of frequency converting temperature carries out certain increase, the second valve is then
Close so that the low temperature refrigerant flowed out from outdoor heat exchanger is more in the flow of heat dissipation region unit interval, so that frequency conversion
The temperature of module also rapid decrease；
Further, because the temperature sensor on frequency-variable module is the real-time temperature and real-time Transmission for obtaining frequency-variable module
The master control borad for being used to control to convertible frequency air-conditioner, so the aperture of first valve is also in real time with the temperature of frequency-variable module in 301
What degree was converted and changed.
302nd, when it is determined that frequency-variable module temperature is less than or equal to Second Threshold, the first valve is reduced according to the temperature of frequency-variable module
The aperture of door, and open the second valve.
Specifically, now the aperture of the first valve is because the size of frequency converting temperature carries out certain reduction, the second valve is then
Open so that the low temperature refrigerant flowed out from outdoor heat exchanger is less in the flow of heat dissipation region unit interval, so that frequency conversion
The temperature of module no longer declines or even risen, it is to avoid because the dew condensation phenomenon of the too low generation of temperature.Similarly, first valve
Aperture is also to produce change according to the temperature of frequency-variable module in real time in 302 steps.
It should be noted that the temperature information of frequency-variable module is integrated in itself or temperature of outside addition is passed by frequency-variable module
Sensor is obtained, and air-conditioning master control borad itself is transferred to after temperature sensor obtains the temperature of frequency-variable module, master control borad is it is determined that become
Aforesaid operations are performed after the temperature of frequency module to be controlled the first valve and the second valve.
Further, because 302 steps, which are performed, is possible to the temperature for frequency-variable module occur still less than after a period of time
Two threshold values, so the outlet of the compressor of frequency-variable air conditioner outdoor machine in the embodiment of the present invention also passes through third channel connection radiating
When being provided with three valves on region, third channel, now referring to shown in Fig. 4, another embodiment of the present invention provides a kind of frequency conversion
The cooling means of the frequency-variable module of air-conditioner outdoor unit, including：
401st, when it is determined that the temperature of frequency-variable module is more than or equal to first threshold, the second valve is closed, and according to frequency conversion mould
The temperature of block increases the aperture of the first valve.
402nd, when it is determined that frequency-variable module temperature is less than or equal to Second Threshold, the first valve is reduced according to the temperature of frequency-variable module
The aperture of door, and open the second valve.
403rd, if it is determined that frequency-variable module temperature is less than or equal to Second Threshold, the first valve is reduced according to the temperature of frequency-variable module
Aperture and open the second valve continue after the first predetermined time period, determine frequency-variable module temperature still less than equal to Second Threshold
When, open the 3rd valve.
Specifically, after 402 steps perform a period of time, when the temperature of frequency-variable module is still less than Second Threshold, just needing
Open the refrigerant collection during the 3rd valve causes the refrigerant major loop of the high temperature refrigerant and heat dissipation region exported from compressor outlet
Close, so that the temperature of heat dissipation region rises.
404th, when it is determined that frequency-variable module temperature is more than or equal to three threshold values, the 3rd valve is closed.
Because final purpose needs for what frequency-variable module was cooled, so after the risk without condensation, it is impossible to
So that the temperature liter of frequency-variable module is too many.
Specifically, in above-described embodiment, first threshold>3rd threshold value>Second Threshold, Second Threshold is usually than frequency conversion mould
Clotting dew temperature higher temperature again, so can cause whole airconditioning control to have the time adjusted in time.
