Test Operation & Troubleshooting & Maintenance
Plate Heat
Exchanger
It is the water-refrigerant plate type heat exchanger, used to
liquefy the high-temperature high-pressure vapor refrigerant or
evaporate the low-temperature low pressure liquid refrigerant.
Heat of condensation is taken away by circulation water and
heat for evaporation is supplied also by circulation water.
Water Pump
It is the power equipment for water circulation.
Expansion Tank
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 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.
Flow Switch
It is used to prevent the heat exchanger from being frozen
owing to reduced water flow rate. When the flow rate goes down
to the point at which the flow switch will act, the switch will trip
off and the unit will raise an alarm and shut down.
Economizer
It is used in heating mode and water heating mode but NOT
used in cooling mode.On one side,it can increase the
subcooling before EXV,and on the other side it can enchance
the refrigerant in heating circuit.
