Apparatus for the maintenance of refrigeration equipment

摘要

The maintenance of refrigeration equipment, for example on board airborne refrigeration equipment, is greatly facilitated by a portable maintenance apparatus. For this purpose the portable apparatus comprises a first section for pressure emptying any refrigeration circulatory conduits by using pressurized nitrogen. A second section including at least one hand operated pump is used for refilling the refrigeration circulatory conduits with refrigerant. Both sections are provided with quick-release couplings for a rapid connection to and disconnection from a refrigeration system. The apparatus also includes a venting device for venting the refrigeration system including any intermediate circulatory conduits.
