What is the primary function of an evaporator coil in an air conditioning system?

Correct! Wrong!

The evaporator coil absorbs heat from indoor air, cooling the air as it passes over the coil.

Which component of the system compresses refrigerant to increase its pressure and temperature?

Correct! Wrong!

The compressor is responsible for increasing the pressure and temperature of the refrigerant, enabling it to transfer heat effectively.

What occurs to the refrigerant in the condenser coil during the refrigeration cycle?

Correct! Wrong!

The refrigerant releases heat to the outdoor air and condenses into a high-pressure liquid.

Which principle explains the heat absorption in the evaporator coil?

Correct! Wrong!

The refrigerant absorbs latent heat during its phase change from liquid to vapor, effectively cooling the air.

What is the primary role of the expansion valve in an air conditioning system?

Correct! Wrong!

The expansion valve reduces the refrigerant's pressure and temperature, preparing it for heat absorption in the evaporator.

Why is refrigerant with a low boiling point ideal for air conditioning systems?

Correct! Wrong!

A low boiling point allows the refrigerant to absorb heat efficiently at room temperature, ensuring effective cooling.
