Question 38Refrigeration & AC - 1st Asst/Chief

The correct answer is C) 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 evaporate and turn into a gas. This evaporator coil is a critical component in the refrigeration cycle, as it facilitates the heat transfer process that ultimately cools the desired space or object. The other options are incorrect because: A) the box solenoid valve is not located directly downstream of the thermal expansion valve, B) the receiver is positioned downstream of the compressor, and D) the compressor is located upstream of the thermal expansion valve.
