In this embodiment, the vacuum valve 33 and the filling valve 31 are preferably solenoid valves.
The working principle is as follows: 2 kinds of refrigerants are respectively connected to a refrigerant input interface 20 of a host 1, an input valve 21 is opened, the refrigerants are filtered by an input filter 22 to enter a refrigerant pressurizing pipeline section through an input one-way valve 23 after impurities are filtered, a gas-liquid booster pump 50 reciprocates under the action of compressed air to pressurize the refrigerants, the pressurization is stopped after pressure sensors 27 on two conveying pipelines 2 detect that the pressures of the two refrigerants are equal, the charging is waited, an energy accumulator 25 absorbs the increased pressure of the refrigerants through a second one-way valve 24, and the pressure of the conveying pipelines 2 is avoided being overlarge.
