Picture 2-9

：

Liquid Pipe Solenoid Valve 

Cut  off  the  refrigerant  supply  circuit  immediately  after  shutdown  to  prevent  the 

evaporator from freezing.   

2.3.3  Hot-gas Bypass Valve 

 

Picture 2-10

：

Hot-gas By-pass Valve 

It  is  used  for  bypass  refrigerant  gas  at  low  temperature  to  avoid  compressor 

frequent start-up for accurate temperature control. 

2.3.4  Flow Switch   

 

Picture 2-11

：

Flow Switch 

The  flow  switch  is  adopted  to  avoid  system  damage  caused  by  the  cold  water 

circulation failure of the water chiller.
