The horizontal barrel pump combination device (R717,CO2, Freon) is an important liquid supply equipment in the refrigeration system. The refrigerant from the liquid receiver is throttled by the throttle valve on the low-pressure circulation barrel into a low-temperature liquid, and multiple times of the low-temperature liquid are supplied to the system heat exchanger through the shielded electric pump. After the heat exchanger absorbs heat, the gas-liquid two phases return to the low-pressure circulation barrel, the gas is sucked by the compressor, and the liquid remains in the low-pressure circulation barrel to continue circulation. The barrel pump has the characteristics of good oil separation effect, convenient oil return, high refrigeration efficiency, good stability and high degree of automation.
