BTUs from the product and the heat of compression are rejected at which of the following?

The correct answer is the condenser because this component plays a crucial role in rejecting heat from the refrigerant. After the refrigeration cycle has absorbed heat from the evaporator, the refrigerant enters the condenser as a high-pressure gas. Here, the refrigerant releases the energy it has collected, which includes both the absorbed BTUs from the product and the heat generated during the compression process.

In the condenser, the heat is expelled to the surrounding environment, typically through air or water cooling. The phase change that occurs here, where the refrigerant transitions from a gas to a liquid, is crucial for the cycle to continue. This heat rejection process is essential for maintaining system efficiency and ensuring effective refrigeration.

The other components mentioned serve different functions in the refrigeration cycle. The evaporator is where the refrigerant absorbs heat; the expansion device regulates the refrigerant flow and lowers the pressure, and the high-pressure receiver holds refrigerant before it enters the condenser, but does not directly handle heat rejection. Therefore, it is the condenser that is responsible for the heat rejection process in the system.
