ABSTRACT:
A refrigeration and defrost system utilizing various valves for opening a defrost line to hot gas and regulating the pressure in refrigerant lines. A slug surge suppressor is provided at several points in the defrost and refrigerant lines to alleviate hydraulic shock damage caused by liquid/gas "slugs" passing rapidly through the lines. The slugs are commonly formed by the required rapid opening of the various valve of the system. Capillary passages in the suppressor resist liquid flow while allowing gas to flow freely.
