Lubrication cycle
Three stages of oil separation ensure excellent compressor lubrication. One is integrated inside the
compressor and the other is a built-in oil separator located inside of the condenser. The refrigerant and
oil mixture is separated in the internal oil separator for the first time, and then is sent to the condenser oil
separator where separating efficiency can reach 99%. Oil returns to the compressor through the oil
return pipe due to the pressure difference. A small amount of oil which remains in the evaporator will be
sucked up by the Venturi tube and returns to the compressor after the gas evaporates. This is the third
stage of oil separation. These three oil return circuits can guarantee reliable oil return efficiency.
