| Resumen: | This document describes the calculation of: - mass flow for sizing pressure relief devices for parts of refrigerating systems; - discharge capacities for pressure relief valves and other pressure relief devices in refrigerating systems including the necessary data for sizing these when relieving to atmosphere or to part of the refrigerating system at lower pressure; - the pressure loss in the inlet and outlet lines of pressure relief valves and other pressure relief devices and includes the necessary data. This document specifies the requirements for selection of pressure relief devices to prevent excessive pressure due to internal and external heat sources, the sources of increasing pressure (e. g. compressor, heaters, etc.) and thermal expansion of trapped liquid. NOTE The term "refrigerating system" used in this document includes heat pumps. |
