Why air cooled water chiller has alarm for compressor high pressure?
Q: Why air-cooled water chiller has alarm for compressor high pressure
A: There are two possibilities lead chiller compressor high pressure alarm;
1, condenser dirty
If the water chiller condenser is dirty, the heat dissipation will be poor, that will leads gas with high pressure in gas loop, and alarm and indication will be showed Compressor Pressure High;
2, Poor ventilation
If the water chiller installed with a closed or poor ventilation place, the heat from condenser cannot be dissipated, the ambient temperature around air cooled water chiller will be continuously increasing. Compressor high pressure alarm will be happened.
For air cooled chiller, the heat generated and transferred by compressor can
only be removed by ambient air, so the ventilation is very important. (See
picture 1-1, regular installation condition).
Installation site should be drafty or
equipped with air duct.
If the long duct influence the dissipation effect, a fan
motor with same or bigger air volume should be mounted at the outlet of it.
When install air duct, please make space for future maintenance.
