Heat Pumps Quiz

What are the two types of heat pumps ?

• Ground source heat pump and water source heat pump

• Air source heat pump and solar heat pump

• Ground source heat pump and air source heat pump

• Water source heat pump and solar heat pump

At what temperature is there no heat energy to be extracted?

• 0°C

• -10°C

• 100°C

• Absolute zero (0K or -273°C)

What is the primary function of a heat pump?

• To cool down the air in a room

• To convert solar energy into electricity

• To heat homes using energy from the ground or air

• To generate electricity from wind

What happens to the refrigerant in a heat pump when it is heated?

• It turns into a solid

• It changes into a gas

• It remains a liquid

• It evaporates completely

What role does the compressor play in a heat pump?

• It cools down the refrigerant

• It compresses the refrigerant, causing it to heat up

• It converts the refrigerant into electricity

• It filters impurities from the refrigerant

What happens to the refrigerant after it releases heat in the system?

• It turns into a solid

• It evaporates

• It changes back into a liquid

• It remains a gas

What is the primary function of the condenser in the refrigeration process?

• To compress the refrigerant

• To expand the refrigerant

• To cool and condense the refrigerant

• To heat the refrigerant

What role does the expansion valve play in the refrigeration process?

• It compresses the refrigerant

• It expands the refrigerant

• It condenses the refrigerant

• It evaporates the refrigerant

In the refrigeration process, what is the function of the evaporator?

• To heat the refrigerant

• To condense the refrigerant

• To evaporate the refrigerant

• To compress the refrigerant

What happens to the efficiency of the system as the difference between the refrigerant and the heat source increases?

• The efficiency decreases

• The efficiency remains the same

• The efficiency increases

• The efficiency becomes zero
