Heating, cooling and desalination system and process by absorption-ejection

Abstract

The present invention relates to a system and process for heating, cooling and desalination by absorption / ejection, the operating principle of which is based on the opening of the conventional absorption cooling cycle and the incorporation of an ejector, in order to simultaneously produce heating, cooling and desalination services. The opening of the conventional absorption cooling cycle is carried out in the pipeline connecting the condenser and the expansion valve, so that the liquid in liquid state from the condenser is not sent to the refrigerant expansion valve to lower its temperature, but is sent to a storage vessel for destination as product water. The cooling fluid entering the evaporator to be cooled now comes from the body of water intended to be desalinated. The ejector is incorporated into the high pressure zone between the desorber and the condenser and activated with the steam from the desorber to suction steam from the evaporator in order to increase water production and heating and / or cooling without modifying the concentration ratio in the solution circuit between the desorber and the absorber.
