Abstract

The present invention relates to an absorption type air conditioner integrally constructed and concentrically installed with an external cylinder serving as an evaporator and an absorber during cooling operation, an external cylinder for precooling a solution, and an internal cylinder of a condenser. The internal cylinder concentrically disposed to act as a condenser via air cooling fins inside the first and second outer cylinders serving as the evaporator and the absorber, and receives the high temperature and high pressure refrigerant vapor generated through the steam transfer pipe. A plurality of branch pipes each supplying a constant refrigerant vapor to the inner cylinder, a refrigerant tank collecting the refrigerant liquid condensed in the inner cylinder through the plurality of branch pipes, and a refrigerant liquid collected in the refrigerant tank as a first connection. Refrigerant distributing refrigerant liquid on the surface of the cold water pipe to cool the cold water flowing through the cold water pipe that is supplied through the pipe and is disposed in a spiral shape. After supplying the liquid distributor and the high temperature and high pressure concentrated solution generated from the generator to the solution heat exchanger, the concentrated solution is supplied to the upper portion of the second outer cylinder to cool, and the refrigerant vapor evaporated from the surface of the cold water pipe. A concentrated liquid distributor that absorbs and sprays the inner wall surface of the first outer cylinder to absorb and release the heat of absorption, and the condensed refrigerant liquid not evaporated from the cold water pipe surface flows down the inner wall surface of the first outer cylinder. Characterized in that it consists of a refrigerant liquid separation means for separating the solution, there is a very excellent effect that can improve the cooling efficiency by recycling the condensation refrigerant not evaporated on the surface of the cold water pipe separated by the refrigerant liquid separation means to the refrigerant cycle. .
