5.4 Maintenance of water side
After the bottom plate is horizontal, connect the water pipe of SHELL&TUBE heat exchanger. Because the
SHELL&TUBE heat exchanger will be cleaned or changed, the exterior pipe should be disassembled. The
discharging valve should be installed on the higher position to ensure the air can be exhausted completely. The
water relief valve is installed on the lower position to discharge water easily.
On the water circuit, there is the temperature indicator and the pressure indicator. In order to
disconnect the unit and the exterior pipe in maintenance, the stop valve is installed on the water circuit. To
reduce the block in the evaporator, it is important to deal with water before the chilled water enters the
evaporator. After the whole system is full of water, startup the pump to exhaust the air in the system.
Even if the cool load changes, heat pump unit also need to operate under the stable water flow. Generally,
the unit can operate normally under the design water flow with tolerance of plus/minus 10%. The changing water
flow can result in unstable operation control, especially for the control of cool/hot water inlet/outlet temperature.
