Make the cooling water re–circulate in the closed loop using a chiller unit.
The cooling requirements of the chiller are as below.
(1)Chiller capacity
Type Capacity
C1500B >15.7kW
C2000B, C2000C >22kW
C3000C, C3000D >33.7kW
C4000A >44.2kW
C6000B >67.5kW
(2)Temperature control range 20 to 30°C
(3)Temperature accuracy "1°C
(4)Water pressure 5.0 bar or less
(5)Heat exhaust Water cooling or air cooling
(6)Attachment
f Water filter
f Water valve
f Flow switch
f Interface to externally switch of chiller
f Contact interface to send signal of normal operation of
chiller(CLRDY).
Note
Output the signal of “contact on” when everything is normal
with cooling water flow rate, temperature, water level,
overheat switch of chiller, high and low pressure switch,
over–current relay, etc.
Throughout the year, set the chiller water temperature to 27°C in general
regions and 30°C in humid regions.
