Maintenance Considerations
notes
Guideline 3, “
Reducing Emission of Halogenated Refrigerants in Refrigeration
and Air Conditioning Equipment and Systems
,” is one of several advisory
documents published by the American Society of Heating, Refrigerating and
Air-Conditioning Engineers (ASHRAE). This guideline includes a list of
recommended data points to be logged daily for each chiller. Much of this data
may be available from the display on the chiller control panel.
Special attention should be given to:
■ Reviewing the operating log and trends
■ Observing the oil pressure drop to determine if the oil filter needs to be
replaced
■ Monitoring evaporator and condenser approach temperatures
■ Observing and recording the oil level
■ Monitoring purge pump-out operation
