| The compressor used in a water-cooled air conditioning system is short cycling. A service check determines that the suction pressure remains above the normal cut-in point during cycling and that the discharge pressure rapidly builds up to the cut-out point while running and gradually falls to the cut-in point during the off cycle. What is likely the cause? |
| A) back seated discharge service valve |
| B) reduction in condenser water flow (scaled condenser) |
| C) front seated liquid line service valve |
| D) loosely fitted compressor drive belt |
