HRS090-W-l
(Water-cooled refrigeration)
HRS090-A-l
(Air-cooled refrigeration)
¡ 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 vaporizes by
taking heat from the circulating fluid in the heat exchanger.
¡ The vaporized 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.
Refrigeration circuit Circulating fluid circuit
For water-cooled refrigeration HRSl-W-l
¡
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.
Facility water circuit
Point
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 realizes high temperature stability even
with a
small-size tank
. Also, contributes to space-saving.
Point
The combination of precise control of expansion valve A
for cooling, and expansion valve Bfor heating realized
high temperature stability.

e.g. in winter at night, the pump operates au-
tomatically and the heat generated by the
pump warms the circulating fluid, preventing
freezing.

Required Cooling Capacity Calculation
Example 1: When the heat generation amount in the user’s equipment is known.
The heat generation amount can be determined based on the power consumption or output
of the heat generating area — i.e. the area requiring cooling — within the user’s equipment.*
