mixed state and enters the lower part of the evaporator. It is then spread into a wider surface by
distributor. Finally the distributed refrigerant evaporates by taking the heat from the chilled water inside
the evaporator tube and repeats the cycle.
Lubrication cycle
Three stages oil separation ensure the excellent compressor lubricant. One is integrated inside the
compressor and the other is built-in oil separator located inside of the condenser. The refrigerant and oil
mixture gets separated in the internal oil separator for the first time and then to the condenser oil
separator of which the separating efficiency can reach 99%. Oil will return to compressor through the oil
return pipe by pressure difference. Small amount of oil which remains in the evaporator will be sucked up
by the Venturi tube and goes back to compressor after gas evaporating. This is the third stages oil
separation. These three oil return circuits can guarantee reliable oil return efficiency.
