Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, not
For limiting the application.
Gas-liquid separating method provided by the present application can be applied in application environment as shown in Figure 1.Wherein, gas-liquid point
From between device 100 and oil catcher 200 be equipped with third oil return solenoid valve 300,400 phase of gas-liquid separator 100 and compressor air suction mouth
It connects, baroceptor is equipped at compressor air suction mouth 400.When liquid refrigerants shape in starting air-conditioner set, gas-liquid separator 100
State declines for no liquid refrigerants or liquid refrigerants, then opens third oil return solenoid valve 300, oil catcher 200 and gas-liquid separator 100
Between form access, liquid refrigerants in oil catcher 200 is migrated to gas-liquid separator 100；When the air pressure of compressor air suction mouth 400
Value reaches the first preset alarm value, then closes third oil return solenoid valve 300.
In one embodiment, as shown in Fig. 2, providing a kind of gas-liquid separating method, it can be applied to shown in FIG. 1 answer
With in scene, comprising the following steps:
Step 202, start air-conditioner set, obtain liquid refrigerants state in gas-liquid separator 100.Wherein, gas-liquid separator
The 100 mountable entrances in gas compressor are used for gas-liquid separation.
Specifically, obtaining liquid refrigerants state in gas-liquid separator 100, liquid refrigerants shape first when opening air-conditioner set
State can be the states such as no liquid refrigerants, liquid refrigerants decline or liquid refrigerants rising.
Step 204, if liquid refrigerants state declines for no liquid refrigerants or liquid refrigerants, the first oil return solenoid valve is opened
Group forms access between oil catcher 200 and gas-liquid separator 100, and liquid refrigerants in oil catcher 200 is migrated to gas-liquid separation
Device 100.
Specifically, opening the first oil return solenoid valve if liquid refrigerants state declines for no liquid refrigerants or liquid refrigerants
Group makes to form access between oil catcher 200 and gas-liquid separator 100, the liquid refrigerants of part in oil catcher 200 is gradually migrated
Into gas-liquid separator 100, make to maintain a small amount of liquid refrigerants in gas-liquid separator 100, air conditioner made to run well, avoid because
Liquid refrigerants all detaches in Liquid segregation device, causes the problem that air-conditioning system is unstable.
Step 206, the atmospheric pressure value for obtaining compressor air suction mouth 400 is closed if atmospheric pressure value reaches the first preset alarm value
First oil return solenoid valve group.Wherein, the first preset alarm value is alarm for high voltage value.
Specifically, compressor air suction mouth 400 gradually generates air pressure, if air pressure sensing when opening the first oil return solenoid valve group
When the atmospheric pressure value for the compressor air suction mouth 400 that device obtains reaches early-warning for high pressure value, then oil return solenoid valve is closed, interrupts oil catcher
Liquid refrigerants is migrated to the process of gas-liquid separator 100 in 200, and it is excessively high to avoid 400 air pressure of compressor air suction mouth, compressor
Blocking.
In above-mentioned gas-liquid separating method, make to form access between oil catcher 200 and gas-liquid separator 100, by oil catcher 200
The liquid refrigerants of middle part is migrated into gas-liquid separator 100, makes air conditioner steady running, while detecting compressor air suction mouth
400 atmospheric pressure values avoid air pressure excessively high, block compressor, refrigerating efficiency is caused to decline.
