Heat Pump System Quiz

What are the main components of a heat pump system?

• Fan, Coil, Filter, Duct

• Generator, Transformer, Circuit Breaker, Switch

• Boiler, Radiator, Thermostat, Pump

• Compressor, Condenser, Expansion Valve, Evaporator

Why is it important not to compare your heat pump's figures with the example in the video?

• Because the example is for a different type of heat pump

• Because the example is outdated

• Because the example is incorrect

• Because the example is purely for understanding and may not match your specific heat pump

In heating mode, where is the evaporator located?

• In the basement

• In the attic

• Outside the building

• Inside the building

In cooling mode, where is the condenser located?

• In the attic

• Outside the building

• Inside the building

• In the basement

What is the role of the expansion valve in a heat pump system?

• To increase the pressure of the refrigerant

• To cool the refrigerant

• To decrease the pressure and temperature of the refrigerant

• To heat the refrigerant

At point 1 in the refrigerant cycle, what is the state of the refrigerant?

• Low-pressure, low-temperature liquid vapor mix

• High-pressure, high-temperature superheated vapor

• Low-pressure, low-temperature saturated vapor

• High-pressure, medium-temperature saturated liquid

At point 2 in the refrigerant cycle, what is the state of the refrigerant?

• High-pressure, high-temperature superheated vapor

• Low-pressure, low-temperature saturated vapor

• High-pressure, medium-temperature saturated liquid

• Low-pressure, low-temperature liquid vapor mix

At point 3 in the refrigerant cycle, what is the state of the refrigerant?

• High-pressure, high-temperature superheated vapor

• Low-pressure, low-temperature saturated vapor

• High-pressure, medium-temperature saturated liquid

• Low-pressure, low-temperature liquid vapor mix

At point 4 in the refrigerant cycle, what is the state of the refrigerant?

• Low-pressure, low-temperature liquid vapor mix

• High-pressure, medium-temperature saturated liquid

• Low-pressure, low-temperature saturated vapor

• High-pressure, high-temperature superheated vapor

What happens to the entropy of the refrigerant at point 4?

• It remains the same

• It decreases significantly

• It increases significantly

• It increases slightly
