Question 3Refrigeration/AC - QMED70% to pass
If it is necessary to increase the operating head pressure of the refrigeration system using the device shown in the illustration, what should be done? Illustration GS-RA-14
AI Explanation
The correct answer is C) "2" should be turned to further compress the spring.
Turning "2" to further compress the spring will increase the operating head pressure of the refrigeration system. This is because the spring is responsible for maintaining the pressure in the system, and compressing it will raise the overall pressure.
The other options are incorrect because rotating "4" to compress or relax the bellows would not directly affect the operating head pressure, and turning "2" to relax the spring would decrease the pressure rather than increase it.
