Flooded type water cooled screw chiller (PCB Control)
20
Ball valve can protect life and property because it can prevent refrigerant from flowing into the air when
safety valve is opening or replaced.
6.2.6 Evaporator
Flooded shell and tube evaporator operates with refrigerant in shell and water in tubes. Replaceable
water tubes are fabricated from integral finned cooper and mechanically bonded to steel tube sheets.
The evaporator is GB151-1999 (Chinese standard) designed, constructed, inspected and stamped.
Water side working pressure is designed for 1.0Mpa. Shell and non-connection water head are insulated
with 3/4” thick closed cell insulation.
6.2.7 Condenser
Shell and tube operates with refrigerant in shell and
water in tubes. Replaceable water tubes are fabricated
from integral finned cooper and mechanically bonded
to steel tube sheets. The condenser is GB151-1999
(Chinese Standard) designed, constructed, inspected
and stamped. Water side working pressure is designed
for 1.0Mpa.
The condenser is used high-efficient tubes to enhance its transfer performance. Meanwhile, the system's
COP can be increased largely by adding the subcooler.
6.2.8 Oil separator
The oil separator with unique structure separate oil from refrigerant high-efficiently. It is solve the oil
recycle problem by ensure oil return to compressor normally.
6.2.9 Throttle parts
The unit achieves high-efficiency when full load and part load by parallel connecting orifice and EXV.
