What are the main components of an air conditioning system?

The main components of an air conditioning system are essential for its operation and efficiency. The correct components include the compressor, evaporator, condenser, and expansion valve.

The compressor is responsible for circulating the refrigerant throughout the system, compressing it to increase its pressure and temperature. This process is crucial as it sets the refrigerant on its path to absorb heat from the inside air and release it outside.

The evaporator is where the refrigerant absorbs heat from the indoor air, causing it to evaporate and cool the surrounding area. This component is key to the cooling process, as it takes the heat out of the air that is being conditioned.

The condenser, located outside the building, is where the refrigerant releases the heat absorbed from indoors. As the refrigerant passes through the condenser coils, it changes from a gas back into a liquid, a critical step in the refrigeration cycle.

The expansion valve acts as a meter for the refrigerant flow, allowing it to expand and decrease in pressure before entering the evaporator. This reduction in pressure is necessary for the refrigerant to effectively absorb heat in the evaporator stage.

Together, these components work in conjunction to create a system that regulates indoor temperatures, making option B the correct choice. The other
