Compressor

Condenser

Fan 
(for condenser)

Electronic 
expansion valve

Evaporator

Oil pump

Relief valve

Rubber hose

Sucks and compresses the low-temperature, 
low-pressure gas refrigerant produced in the 
evaporator, to produce high-temperature, 
high-pressure gas.

Conducts heat exchange between the high-temperature, 
high-pressure gas refrigerant produced in the 
compressor and the air, to produce high-temperature, 
high-pressure liquid refrigerant.

Forcefully blows air to accelerate heat exchange 
between the refrigerant in the condenser and the air.

The valve mechanism reduces pressure of the 
high-temperature, high-pressure liquid refrigerant 
produced in the condenser, to produce low-temperature, 
low-pressure liquid/gas mixed refrigerant.

Motor valve for 
hot gas

The cooling capability of low load operation is 
controlled by bypassing the refrigerant from the high 
pressure side to the low pressure side.

Sucks oil from outside of the unit, and discharges it 
from the unit through the evaporator.

Evaporates the low-temperature, low-pressure liquid 
refrigerant produced in the electronic expansion valve by 
conducting heat exchange between the refrigerant and oil, 
to produce low-temperature, low-pressure gas refrigerant.

Limits the oil pump discharge pressure within a 
specified level.

A part of the oil piping for suction and discharge of 
the oil pump.

Heater (“–H” only)

Transformer 
(“–047, –048” only)

Oil tank 
(“–T” only)

Located at the front of the condenser. It is intended 
to prevent cooling capacity deterioration by 
eliminating dust adhering to the condenser from the 
air intake.

Drains oil from the evaporator when the Oil Cooling 
Unit is re-located.

Oil drain 
(drain pan)

The oil accumulated at the bottom of OILCON can 
be discharged from here.

Tripped when high-pressure alarm is activated. It is 
intended to protect the refrigerant system for the 
condenser etc.

Tripped when compressor head high-temperature 
alarm is activated. It is intended to protect the 
compressor.

Tripped when over-current flows through the circuit. 
It is intended to protect the internal electric wiring.

During warm-up in winter, the electric heater heats 
up the oil to a preset temperature.

Intended for the different-voltage model.

Receives oil from the main machine oil piping 
system. The oil tank can accept an 
increase/decrease in oil quantity.
