low pressure liquid refrigerant. Heat of condensation
evaporation is supplied also by circulation water.
Water Pump
It is the power equipment for water circulation.
It is used to keep stable pressure of the water system.
The tank is charged with a certain volume of nitrogen
which is separated from the water side with a gasbag.
When pressure of the water side exceeds the nitrogen
Expansion Tank
pressure, the gasbag will expand and water enters
into the tank so as to lower the pressure of the water
system. In contract, when pressure of the water
system goes down, nitrogen in the tank will expel
water out to the water system.
