how to pumping refrigerant to water chiller system
- Dec 07, 2018-
In order for industrial chillers to operate normally and safely, refrigerants cannot be separated. When the small industrial chiller device uses the quantitative filling device to charge the refrigerant, it is only necessary to close the three-way valve and stop the vacuum pump after the vacuum is pumped. The joint of the pressure-resistant hose connected to the vacuum pump is removed and installed in the discharge chamber of the quantitative filling device; or the joint of the pressure-resistant hose connected to the three-way valve can be removed, and the quantitative filling device is connected The pressure hose is connected to the connector of the valve.
When the industrial chiller is charged with refrigerant by the pumping and filling machine, it is only necessary to close the evacuation stop valve on the pumping and filling machine after opening the pumping, and open the liquid filling shut-off valve to charge the refrigeration system with refrigerant.
