Abstract
The present invention is a pretrip routine for testing a refrigeration system comprising a series of tests for testing aspects of mechanical operation of various individual components of the refrigeration system. In a preferred embodiment, a control unit executes the method of the invention by first testing mechanical operation of a refrigeration system compressor, then tests for leaks in high-to-low-side valves of a refrigeration system, before testing for leaks in a discharge test valve. A control unit may also test the opening/closing operation of various refrigeration system valves before, intermediate or subsequent to executing the above tests. The pretrip routine of the invention validates operation of a refrigeration system as a whole by testing the mechanical operation of individual system component, and, in testing the operation of those various system components, readily isolates the source of a particular problem within a particular component of a refrigeration system.
