Question 109Refrigeration & AC - Assistant Engineer

The correct answer is A) evaporator coil. In a refrigeration system, the thermal expansion valve is responsible for regulating the flow of refrigerant into the evaporator coil. Directly downstream of the thermal expansion valve, the refrigerant enters the evaporator coil, where it absorbs heat from the surrounding environment, causing it to vaporize. This vaporization process is a critical step in the refrigeration cycle, as it allows the system to remove heat and provide cooling. The other answer choices are incorrect because the receiver is located downstream of the condenser, the compressor is upstream of the thermal expansion valve, and the box solenoid valve is not a standard component in a basic refrigeration system.
