Question 45Refrigeration & AC - QMED

The correct answer is A) the suction line of the compressor will be abnormally warm. If the superheat value of the thermostatic expansion valve is adjusted too high, it will cause the expansion valve to open less, resulting in the evaporator being overfed with liquid refrigerant. This will lead to liquid refrigerant entering the compressor, causing the suction line to become abnormally warm. The other answer choices are incorrect because increasing the heat removal capacity of the evaporator (B) and overfeding the evaporator with liquid refrigerant (C) are the opposite effects of adjusting the superheat too high, and the suction line becoming abnormally cold (D) is not the result of this adjustment.
