ADSORPTION REFRIGERATION MACHINE OR HEAT PUMP WITH A LIQUID-PHASE REFRIGERANT DISTRIBUTION FUNCTION, AND METHOD FOR OPERATING THE ADSORPTION REFRIGERATION MACHINE OR HEAT PUMP
The invention relates to an adsorption refrigerator or an adsorption heat pump as well as a method for the operation thereof. The adsorption refrigerator or adsorption heat pump comprises at least one module having an adsorber, a mixing evaporator and a mixing condenser. It is characterized in that the adsorber together with the mixing evaporator and the mixing condenser within the module is structurally combined and contained within a common, preferably thermally insulated adsorber container for accommodating the adsorber and having an adsorber section which can be thermally contacted externally, and having a mixing section thermally insulated externally for accommodating the mixing evaporator and the mixing condenser, wherein the mixing section is formed so that a refrigerant can flow through it, so that the refrigerant, after having flown through the mixing section, can be supplied to an external heat exchanger that is separated from the module, wherein the mixing section is arranged to enable the refrigerant to be evaporated and/or condensed.

Purge system for closed-cycle absorption heat pumps
A high-efficiency, motorless purge system for closed-cycle absorption heat pumps, adapted for both absorption heat transformers and absorption chillers, using a series of valves to control the entry and exit of absorbent solution into a low-pressure, secondary absorption vessel. A small percentage of the total circulating solution is forced under pressure into the secondary absorption vessel via a spray nozzle, causing adiabatic absorption of absorbate vapor by the solution. Non-condensable gases accumulate in the secondary absorber until a certain vapor pressure is reached, upon which, gas, and possibly liquid, are transferred to an exhaust vessel having an exit vent for non-condensable gases. In an absorption chiller system, the secondary absorber has an internal heat exchanger to lower the temperature of the solution within, to facilitate the absorption process.
