Question 66Refrigeration/AC - QMED70% to pass
What is the purpose of the pressure transducer as shown in the illustration? Illustration GS-RA-17
AI Explanation
The correct answer is A) it senses compressor suction pressure and controls the quench valve.
The pressure transducer shown in the illustration GS-RA-17 is used to sense the compressor suction pressure and control the quench valve. The quench valve is responsible for regulating the flow of refrigerant to the compressor, and the pressure transducer helps maintain the appropriate suction pressure by adjusting the quench valve as needed.
The other options are incorrect because they do not accurately describe the function of the pressure transducer in this particular system. Option B and C mention the suction modulation valves, which are not part of the system depicted in the illustration. Option D refers to the compressor discharge pressure, which is not the parameter being monitored by the pressure transducer in this case.
