Abstract
A method is provided for determining whether leaks are present in a discharge check valve of a refrigeration system. The method includes steps of establishing a pressure difference between a high pressure side and a low pressure side of the refrigeration system, temporarily stopping compression of a refrigerant, allowing the refrigerant to flow to the low-pressure sides, and then determining the discharge pressure changes with time.
