HVAC Experts Answer 3 Commercial Refrigeration FAQs

My Refrigerator Requires a Manual Reset Due to Oil Pressure Failure, But the Oil Pressure Seems Normal After Restart. What Could the Problem Be?

This can be caused by a number of things, including a low oil level, improperly sized refrigerant piping, refrigerant migration, improper settings on system controls, electrical issues, or internal compressor issues. It could also simply be from seasonal temperature changes when it’s cold at night and warm during the day. This sometimes causes the oil control to trip. If you frequently experience this problem, it’s best to call your local commercial refrigeration specialist to diagnose and repair your machine.

There Is a Time Delay Relay in the Condensing Unit’s Electrical Panel. What Should This Be Set For?

Set it for one minute. You should see the numbers .1 and 3.5 on the dial. Keep this dial a little less than halfway between the two marks. If you ever need help with other settings on your commercial refrigeration system, you can always have an HVAC technician help.

The Compressor Is Short Cycling Due to Varying Load Conditions. How Can I Prevent This?

Your options will vary depending on the type of compressor and the load variations. But in general, a simple way to prevent this is by increasing the dead band control for the room thermostat. For wider load variations, you can try resolving this through capacity control, including hot gas bypass or mechanical unloaders. This should help balance the system capacity.
