The aperture of second control valve 50 reaches maximum opening.Wherein, preset upper limit temperature is greater than pre-determined lower limit temperature.
With continued reference to Fig. 1, due to the low pressure of the second port connection system of refrigerant heat exchanger 10, if system low-voltage mistake
It is low, then it will lead to the refrigerant of pipeline in entire refrigerant heat exchanger 10 all in low pressure, temperature is low, and condensation risk substantially increases, this
Shi Ruguo reduces the aperture of the second control valve 50, then the low pressure refrigerant of pipeline keeps a constant pressure drop in refrigerant heat exchanger 10, rises
The temperature of high refrigerant heat exchanger 10 reduces condensation risk.
Specific control is as follows, in air-conditioning system operational process, passes through 60 real-time detection refrigerant of the first temperature detecting unit
The refrigerant temperature T1 of the first port of heat exchanger 10, and it is compared with the first temperature threshold a1, meanwhile, pass through the second temperature
Degree 70 real-time detection of detection unit waits for the temperature T2 of thermal component, and its with pre-determined lower limit temperature x1 and preset upper limit temperature x2 into
Row compares.If T1≤a1 and lasting preset time such as tmin, and T2≤x1, then explanation has condensation risk, at this time control unit
The aperture for controlling the second control valve 50 reduces, and such as turns down p step, reduces the cold medium flux for passing through the second control valve 50, solidifying to reduce
It divulges a secret danger；If T2 >=x2, illustrate no condensation risk, the aperture that control unit controls the second control valve 50 at this time directly reaches
Maximum opening；If x1 < T2 < x2, the aperture that control unit if controls the second control valve 50 is remained unchanged.It wherein, is guarantee
The aperture of the flow of refrigerating system coolant, the second control valve 50 is provided with minimum aperture, which can be obtained by experiment.
Further, as shown in figure 3, the adjusting method of the second control valve of the embodiment of the present invention can comprise the following steps that

Real-time detection waits for the temperature T2 of thermal component, and it is compared with x1 and x2.Wherein, x1 < x2.
S302 judges T1≤a1 and lasting tmin, and whether T2≤x1 is true.If so, executing step S303；If
It is no, execute step S304.
S303, the aperture of the second control valve of control turn down P step.
S304 judges whether T2 >=x2 is true.If so, executing step S305；If not, executing step S306.
The aperture of S305, the second control valve of control are directly adjusted to maximum opening.
S306, x1 < T2 < x2, the aperture for controlling the second control valve at this time remain unchanged.
Below in conjunction with the embodiment of the present invention to control unit according to the refrigerant temperature of the first port of refrigerant heat exchanger 10
The method that degree adjusts 40 aperture of the first control valve is illustrated.

The refrigerant temperature T1 of the first port of heat exchanger 10, and it is compared with second temperature threshold value a2.If T1 > a2, control
The aperture that unit then reduces the first control valve 40 reduces T1 to increase throttling action；If T1 < a2, control unit if, increases
The aperture of big first control valve 40 rises T1 to reduce throttling action；If T1=a2, control unit if, controls the first control
The aperture of valve 40 processed remains unchanged.It wherein, is the flow for guaranteeing refrigerating system coolant, the aperture of the first control valve 40 is provided with most
Small guide vane, the minimum aperture can be obtained by experiment.
Further, as shown in figure 4, the adjusting method of the first control valve of the embodiment of the present invention can comprise the following steps that
S401, the refrigerant temperature T1 of the first port of real-time detection refrigerant heat exchanger, and it is compared with a2.
S402 judges whether T1 > a2 is true.If so, executing step S403；If not, executing step S404.
The aperture of S403, the first control valve of control turn down.
S404 judges whether T1=a2 is true.If so, executing step S405；If not, executing step S406.
The aperture of S405, the first control valve of control are kept.
S406, T1 > a2, the aperture for controlling the first control valve at this time are opened greatly.
The embodiment of the present invention as a result, can be by the aperture of adjusting the first control valve and the second control valve, to solve phase
Using the problem of the refrigerant cooling condensation occurred and cooling capacity deficiency in the technology of pass, it is burned to avoid electric-controlled plate and wait radiate
