The precision temperature control method by expansion valve and temperature sensor, realized high temperature
stability of ±0.1°C.
¡The compressor compresses the refrigerant gas, and discharges
the high temperature and high pressure refrigerant gas.
¡In the case of air-cooled refrigeration, the high temperature and
high pressure refrigerant gas is cooled down by an air-cooled
condenser with the ventilation of the fan, and becomes a liquid. In
the case of water-cooled refrigeration, the refrigerant gas is cooled
by a water-cooled condenser with the facility water in the facility
water circuit, and becomes a liquid.
¡The liquefied high pressure refrigerant gas expands and its
temperature lowers when it passes through expansion valve A and
vaporises by taking heat from the circulating fluid in the evaporator.
¡The vaporised refrigerant gas is sucked into the compressor and
compressed again.
¡When heating the circulating fluid, the high pressure and high
temperature refrigerant gas is bypassed into the evaporator by
expansion valve B, to heat the circulating fluid.
¡The circulating fluid discharged from the pump, is heated or cooled
by the user’s equipment and returns to the thermo-chiller.
¡The circulating fluid is controlled to a set temperature by the
refrigeration circuit, to be discharged to the user’s equipment side
again by the thermo-chiller.

For water-cooled refrigeration HRR첸-W
¡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.

The combination of precise control of expansion valve A
for cooling, and expansion valve B for heating realised
high temperature stability.
Since the refrigeration circuit is controlled by the signal from
2 temperature sensors (for return and discharge)
, precise
temperature control of the circulating fluid can be
performed.Therefore, there is no necessity of absorbing the
temperature difference in the circulating fluid with a large
tank capacity, and realises high temperature stability even
with a
small-size tank
. Also, contributes to space-saving.

Hot discharged gas of the refrigerant
is used instead of a heater.
With heating function
Heating method using discharged heat makes a heater unnecessary.
Heating functions are effective to maintain a constant temperature particularly
in the winter when the ambient temperature is low.
