The compressors are basically the same . Very simply put with out getting to technical is what makes a heat pump a heat pump is a reversing valve that changes the direction the refrigerant travels in lines leading to and from the condensing unit and to the coil, without changing direction of flow in they compressor. You should always check with the manufacture before replacing an unlike compressor for compatibility.
Air Compresser
it is necessary to heat the compressor and strike it with a rubber mallet!
In a car the heat usually comes from engine "waste heat". You just need to be running the engine. The compressor is part of the air conditioner, which is used for cooling not heating.
Your compressor has possibly stopped working. If you are lucky, the serviceman will only have to replace the freon to get it going again.
No it's not. But if that's all you can afford then, you have to put the compressor in. You will have a one year warranty on the compressor. If you have a new system put in you can get a ten year warranty on every part. Goodmans and Amana, also have units with lifetime warranties.
enthalpy of air leaving the compressor minus enthalpy of air entering the compressor
Looking through the top by the fan . Look at your compressor if its a heat pumpbyou will have a accumalator which looks like an long can which your copper line runs to and you will also have a reversing valve which is attached in your line sets it will have three copper lines running to it and an electrical line to it also. A straight cool unit you will see nothing but a compressor. Also if your thermostate has a emergency heat most likely its a heat pump.
latent heat
A full day service call plus the cost of the compressor, refrigerant and new driers.Plus perhaps disposal charges of the old one since it contains oil. Depending on the age and condition of your system sometimes it makes sense to replace the entire unit.
No. The compressor is needed to run in reverse in order to pull warm air from the outside to heat the home.
The exact same thing it does in the cooling mode, the change between modes of operation does not take place in the compressor.
Heat pumps use a compressor to make the working fluid condense at a higher temperature.The compressor needs input energy.
