Central air conditions work fundamental to the second law of thermodynamics which states, "Heat always flows from material at high temperatures to material at low temperatures.". There are two heat exchanges in the central air unit named condenser and evaporator. The evaporator coil is located in the room and the condenser coil is located outdoors.

The evaporator coil adds heat to the air conditioning system. You can see other ways. The AC evaporator absorbs heat from the area that needs cool and adds heat into the air conditioning unit. For our decision, the area that needs to be cool is indoor air. You can buy the best central ACs at Metroheat.

As you remember, energy cannot be made or destroyed. The AC unit does not make hot or cold using the AC condenser to refuse heat. Yes, it is true! If you look out of your home, you will see a square metal box outside. It is a condenser unit! This is where he refused to heat. These two components do not require electricity. However, the condenser fan and blower evaporator need electricity to work.

The AC unit absorbs energy in one area and rejects it in a different area. AC compressor is the only mechanical part that requires electric mass to run. The compressor makes refrigerant flow. Condenser AC is located outdoor with a compressor. The condenser was a heat exchange, it refused heat.

Expansion device’s location in an air handler unit. This acts as a restriction for refrigerants. Evaporator AC is located with an Air Handler. The evaporator adds heat to the central air unit. Copper tubing  which connects four shared components. Once, the Refrigerant copper tube connects these components. The cooling cycle is a process that eliminates heat from unwanted areas and transfers heat to a different place.
