Final answer:
The component not used in an ideal vapor compression refrigeration cycle heat pump system is d) Radiator. The main components of such a system are the evaporator, compressor, condenser, and expansion valve.
Step-by-step explanation:
The component that is not used in an ideal vapor compression refrigeration cycle heat pump system is d) Radiator. The four basic components of a simple heat pump system are the evaporator, the compressor, the condenser, and the expansion valve.
The evaporator converts liquid refrigerant into gas, absorbing heat from the environment. The compressor then increases the temperature and pressure of this gas. The high-pressure gas moves to the condenser, where it releases heat and converts back into a liquid. Finally, the refrigerant passes through the expansion valve, where it cools down before returning to the evaporator. Radiators are typically associated with heating systems, not with the refrigeration cycle.
Question 64, which asks which component of an air conditioner converts gas into liquid, the answer is a) the condenser.
