to prevent liquid refrigerant from staying in the compressor after shut down
The formula used to determine the power consumed by a compressor's crankcase heater is the overall volume times the amount of heat generated. This allows a person to purchase the appropriate heater for their application.
A crankcase heater is a small eclectic heater that keeps the compressor oil at a relatively warm temp. This allows the oil to circulate in the system at lower temperatures.
A crankcase heater is used to prevent the accumulation of refrigerant in the compressor's crankcase during periods of inactivity, which can lead to oil dilution and reduced lubrication. By maintaining a temperature above the refrigerant's saturation point, the heater ensures that any refrigerant in the crankcase vaporizes, promoting better oil circulation and compressor efficiency when the unit starts. This is particularly important in refrigeration and air conditioning systems operating in low-temperature environments.
It is flooding liquid back to the crankcase
...It will be what ever your suction pressure is.
what is purpose of a compressor
The ohm reading on a crankcase heater can vary depending on the specific model and manufacturer. However, a common range for a properly functioning crankcase heater is typically between 5 to 30 ohms. It is important to refer to the manufacturer's specifications for the specific heater being tested to ensure accuracy and proper functioning of the equipment.
use a run capacito
The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.
yes it will.
To burn the fumes produced in the crankcase for cleaner emissions. In the old days the crankcase fumes were released in to the atmosphere.
