Abstract: Apparatus for removing and disposing of waste of absorption systems comprising a first and a second adapter for providing connection to the refrigerating system to be emptied; a compressor or compressor connection being connected to the first adaptor via a conduit for compressed air and a valve; a first pressure vessel being in connection with the adapters via pressure pipes and relating valves and having an outlet with a valve for the liquid accumulated in the first pressure vessel; a second pressure vessel connected to the first pressure vessel or tank via a pressure pipe and comprising a fresh water supply, a waste air pipe as well as an outlet with a valve, wherein the pressure pipe starting from the top end of the first pressure vessel leads into the lower half of the second pressure vessel; as well as at least one pressure gauge and a pressure-relief valve on one of the pressure vessels.

Abstract: An absorption refrigerating system for use with refrigerant and inert auxiliary gas. The system includes a generator, a condenser, an evaporator structure and an absorber in circuit with each other. The evaporator structure is arranged to effect a two-stage precooling operation including precooling of the incoming weak auxiliary gas and liquid refrigerant, utilizing for the final precooling of the gas evaporation of a part of the refrigerant into a small partial stream of weak gas and to effect final precooling of the liquid refrigerant by leading it in contracurrent to the gas through a flat evaporator coil such as utilized for cooling the freezer compartment of a refrigerator.
