Circulating Fluid Temperature Controller
Thermo-chiller Dual ChannelRefrigerated Thermo-chiller for Lasers HRL Series

•The inverter 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 inverter 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 inverter compressor and compressed again.
•When heating the circulating fluid, the high-pressure, high-temperature refrigerant gas
is bypassed into the evaporator by expansion valve B to heat the circulating fluid.
•After the circulating fluid discharged from the inverter pump is heated or cooled by
the user’s equipment, it returns to the tank.
•The circulating fluid is sent to the evaporator by the inverter pump, and is
controlled to a set temperature by the refrigeration circuit, to be discharged to the
user’s equipment side again by the thermo-chiller.
Refrigeration circuit Circulating fluid circuit
The combination of inverter control of the
compressor and fan, and the precise
control of expansion valves A and B
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 from2temperature 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.
