ABSTRACT:
An absorption type air conditioning system in which a solar collector is used integrally to heat and strip refrigerant from the mixture of absorbent and refrigerant to eliminate a separated hot water or other heat transfer medium cycle as normally employed between the solar collector and the stripper generator.
Also, the present invention includes an absorber which is integrally located within the confines of a deep water well used to extract heat from the entire system, together with a condenser coil or tube also located within the deep water well. The integral location of absorber and condenser within the confines of the heat sinking medium, such as a deep water well raises the overall cooling efficiency since a separated cooling cycle and heat exchanger are eliminated.
The invention is particularly suited to brine type absorption systems, such as lithium bromide and water solutions where stripper generator action may take place at temperatures easily obtainable with the solar collector process included.
The invention is also suited to ammonia water systems, providing a highly efficient heat removal process with the energy required supplied by solar means.
The system uses a minimum amount of electrical energy. The electrical energy is used primarily for pumping and control purposes, as well as operation of a fan for circulation of air. The conventional compressor used in freon systems is eliminated together with the major requirement of electrical energy in such prior art systems.
