Which component converts refrigerant to low temperature, low pressure gas in an air conditioning system?

In an air conditioning system, the component that converts refrigerant to low temperature, low pressure gas is the evaporator. The evaporator is where the refrigerant absorbs heat from the cabin air, causing it to evaporate and transition from a liquid state to a gas state. This process occurs as the refrigerant passes through the coils of the evaporator, which are usually located inside the vehicle's cabin.

When warm air from the inside of the vehicle blows over the evaporator coils, the refrigerant inside the coils absorbs the heat and evaporates, thereby cooling the air that is released back into the cabin. This is crucial to the cooling function of the air conditioning system.

The other components, such as the compressor, condenser, and expansion valve, play important roles in the overall cycle of refrigeration, but it is specifically the evaporator that is responsible for delivering the low temperature, low pressure gas needed for the cooling effect.
