ABSTRACT:
An air-cooled absorption air-conditioner comprising a high-temperature regenerator for heating diluted solution which has absorbed refrigerant, a separator for separating refrigerant vapor obtained by the high-temperature regenerator from the diluted solution, a condenser for condensing the refrigerant vapor into liquid refrigerant, an evaporator for vaporizing liquid refrigerant, cooling circulation heat medium by the effecting heat exchange between it and the above-mentioned liquid refrigerant vaporized and supplying the circulation heat medium thus cooled to a space to be cooled, an absorber for allowing the refrigerant vapor generated in the evaporator to be absorbed by the solution separated in the separator and removing the heat thereby generated by air-cooling, and a heat-medium-circulation pump for circulating the circulation heat medium, the circulation heat medium being heated using the refrigerant vapor generated in the evaporator and supplied to a space to be heated. The evaporator includes a circulation-heat-medium passage which is in contact with a liquid-refrigerant-evaporation surface of the evaporator, and refrigerant-vapor flow passage connected to the separator and in contact with the circulation-heat-medium flow passage through a heat-transfer surface. A valve is provided at least in that portion of said refrigerant-vapor flow passage where refrigerant flows from this passage to the separator.
