• Evaporation

• Radiation

• Convection

What is the main function of the evaporator coil in an HVAC system?

• To compress the refrigerant

• To absorb heat from the indoor air

• To release heat to the outdoor air

• To circulate air throughout the building

Which component of an HVAC system is responsible for compressing the refrigerant?

• Condenser

• Evaporator

• Compressor

• Expansion valve

How does increasing the SEER (Seasonal Energy Efficiency Ratio) rating of an HVAC system affect its energy efficiency?

• Decreases energy efficiency

• Has no effect on energy efficiency

• Increases energy efficiency

• Only affects heating efficiency

Which of the following is a measure of an HVAC system's cooling efficiency?

• BTU

• SEER

• CFM

• PSI

What is the primary purpose of the condenser coil in an HVAC system?

• To absorb heat from the indoor air

• To release heat to the outdoor air

• To circulate refrigerant

• To filter air

Which of the following is NOT a component of a typical HVAC cooling system?

• Evaporator coil

• Compressor

• Boiler

• Condenser coil

What is the role of the expansion valve in an HVAC system?

• To increase the pressure of the refrigerant

• To decrease the pressure of the refrigerant

• To circulate air

• To filter the refrigerant

Which of the following factors can improve the energy efficiency of an HVAC system?

• Using a single-speed compressor

• Increasing the thermostat setting

• Regular maintenance and cleaning

• Reducing insulation

What does the term "latent heat" refer to in the context of HVAC cooling?

• Heat absorbed by the refrigerant

• Heat released by the refrigerant

• Heat required to change the state of a substance without changing its temperature

• Heat that is lost through the ductwork
