This Practice specifies requirements for packaged, skid-mounted industrial process refrigeration systems. Along with the data sheet, appendix, and referenced attachments, this Practice defines the minimum requirements for the performance, design, fabrication, testing, inspection, and preparation for shipment of packaged, skid-mounted process refrigeration systems. This Practice is not intended to cover commercial or absorption chiller systems.The refrigeration package shall provide liquid refrigerant to its chiller(s) (evaporator[s]) in the quantity and at the temperature necessary to produce the specified process temperature and refrigeration duty. The refrigeration system shall consist of a complete package with all components (compressor, evaporator, condenser, driver, etc.) factory mounted, piped, and wired. A single skidded system is preferred. Multiple baseplates designed to facilitate shipping shall not be acceptable unless written approval is received from purchaser.
