What is NOT a component of the refrigeration cycle?

In the refrigeration cycle, the main components work together to transfer heat from one place to another, allowing for cooling. The evaporator is where the refrigerant absorbs heat from the environment, evaporating from a liquid to a gas. The compressor then increases the pressure of this gas, preparing it for heat rejection. Following this, the condenser cools the gas back into a liquid by releasing heat absorbed in the evaporator.

A radiator, while it does have its place in cooling systems, is not a part of the refrigeration cycle. It is primarily used in systems such as automotive cooling or heating systems, where it dissipates heat but does not directly participate in the process of cooling via the refrigeration cycle. Therefore, identifying the radiator as not being a component emphasizes the correct understanding of the specific roles played by components in the refrigeration cycle.
