Question

What steps may be taken to prevent air accumulation into an idle low pressure refrigeration system? a) Leave the purge unit on-line at all times. b) System pressure should be maintained slightly above atmospheric. c) Open the air vents on the condenser. d) Intermittently operate the system with no load.

Answer 1

Steps that may be taken to prevent air accumulation into an idle low pressure refrigeration system include leaving the purge unit on-line, maintaining slightly above atmospheric pressure, and intermittently operating the system with no load.

Step-by-step explanation:

One of the steps that may be taken to prevent air accumulation into an idle low pressure refrigeration system is to leave the purge unit on-line at all times. This helps to remove any air that enters the system. Another step is to maintain the system pressure slightly above atmospheric pressure. This helps to prevent air from entering the system. Additionally, intermittently operating the system with no load can also help to prevent air accumulation.
