to prevent liquid refrigerant from staying in the compressor after shut down

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.

...It will be what ever your suction pressure is.

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.

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.

Air compressor for what purpose?

To burn the fumes produced in the crankcase for cleaner emissions. In the old days the crankcase fumes were released in to the atmosphere.

The purpose of a heater is to heat up the room when it is cold; by using gas

The main purpose of the turbine in the turbojet engine is to drive the compressor. The compressor compresses air in the engine to enable it to function.

Not constantly, but it will kick on from time to time.

It compresses the air in a engine or compressor.

An item designed for the purpose of unloading an air compressor at the end of a pumping operation or at any time when voltage failure occurs.

YES. The A/C will cycle on and off when the heater is on defrost. That stops the A/C compressor from locking up during the winter months.

NO! the compressor has oil in the crankcase similar to a car. The compressor relies on among other things gravity to return the oil back. There are window shakers out there that will fit your application, just not this one.

To prevent wear on the compressor.

As long as you have a heater strip installed on the compressor, you will not have a problem.

Check to see if the a/c compressor is not locked up first..........

The turbine drives the compressor. The compressor compresses air inside the engine so it can function.

To keep the oil warm. Cold oil is thicker (think 'higher viscosity') than warm oil, and, as a result, takes longer to circulate to areas that need it. Keep the oil warm, and it circulates more quickly on equipment start-up.

The purpose of the PCV valve is to regulate the flow of crankcase fumes into the intake manifold where they can be burned. Prior to 1963, cars had no PCV and used road draft tubes that just left the hydrocarbon emissions from the crankcase out into the open air. The PCV valve also has a secondary role as a check valve, to prevent flow back into the crankcase. This prevents potential ignition of the crankcase fumes, should the engine backfire. The PCV system is also crucial for to proper engine sealing. The system alleviates crankcase pressure, which can push out on seals and gaskets, contributing to oil leaks.

The AC switch operates the AC compressor and should have no bearing on your heater function. If your heater is not working properly, you may have a weak thermostat.

A PCV valve is for positive crankcase ventilation. It is to keep crankcase pressure from building up in the engine. If it does it can cause seal leakage, air filter contamination and engine blowby.

The PCV (Positive Crankcase Ventilation) valve allows the engine to burn off the gases that build up in the crankcase and at the same time protect the flammable gases from igniting from a backfire.

No. The purpose of a compressor is not to cool it is to compress. A freon compressor keeps freon under pressure to restore its liquid state. If you tried to run oil trhough it the compressor would probably blow up pretty quickly because you can't compress a liquid. You can compress a gas to a liquid but it won't compress beyond that. For an external oil cooler go to a junk yard and get a heater core or even a factory oil cooler from a transmission.
