Aims and Objectives

What does an Air Source heat pump do?

• Transfers heat from inside to outside

• Transfers heat from outside air to inside of a building

• Transfers heat from water to air

• Transfers heat from air to water

Fill in the blank: An Air Source heat pump works by using a refrigerant that’s circulated through a compressor, evaporator, condenser, and _________.

• expansion valve

• compressor valve

• pressure valve

• temperature valve

The function of an evaporator is to:

• absorb heat from the surroundings and vaporize the refrigerant

• compress the refrigerant to increase its pressure

• condense the refrigerant into a liquid

• regulate the flow of refrigerant in the system

What is the function of a compressor in a refrigeration system?

• Decreases the temperature and pressure of the refrigerant gas.

• Increases the temperature and pressure of the refrigerant gas.

• Maintains the temperature and pressure of the refrigerant gas.

• None of the above.

The function of an Expansion Valve is to:

• regulate the flow of refrigerant into the evaporator

• compress the refrigerant gas

• condense the refrigerant into a liquid

• absorb heat from the surroundings
