¡The compressor compresses the refrigerant gas and discharges high-temperature, high-
pressure refrigerant gas.
¡In the case of air-cooled refrigeration, the high-temperature, high-pressure refrigerant gas is
cooled down by fan ventilation in the air-cooled condenser, where it is then liquefied.
¡The liquefied high-pressure refrigerant gas expands and its temperature lowers when it
passes through expansion valve A, where it vaporizes after receiving heat from the circulating
fluid in the evaporator.
¡The vaporized refrigerant gas is sucked into the compressor and compressed again.
¡When heating the circulating fluid, the high-pressure, high-temperature refrigerant gas is
bypassed into the evaporator by expansion valves B and C to heat the circulating fluid.
¡In the case of water-cooled refrigeration, the refrigerant gas is cooled by the facility water in
the facility water circuit in the water-cooled condenser, where it is then liquefied.
For water-cooled refrigeration
¡ The water-regulating valve opens
and closes to keep the refrigerant
gas pressure consistent. The
facility water flow rate is controlled
by the water-regulating valve.
¡After the circulating fluid discharged from the pump is heated or cooled by the customer
system side, it returns to the tank.
¡The circulating fluid is sent to the heat exchanger by the pump, and is controlled to a set
temperature by the refrigeration circuit, to be discharged to the customer system side
again by the thermo-chiller.
Refrigeration circuit
Facility water circuit
Circulating fluid circuit
The combination of the precise control
of expansion valves A, B, and C
realizes energy saving operation
without waste and high temperature
stability.
Adjusting the
discharge
pressure by pump
inverter control
eliminates wasteful discharge
of the circulating fluid and
realizes energy saving
operation.
Since the refrigeration circuit is
controlled by the signals from 2
temperature sensors (for return and
discharge), precise temperature control
of the circulating fluid can be achieved. Therefore,
there is no need for a tank with a large capacity
to absorb the circulating fluid temperature
difference, as high temperature stability can be
achieved even with a small-size tank. This also
contributes to space saving.
One compressor controls
2 channels which realize
the independent
temperature control of 2
systems.
