Absorption solar powered air conditioning system with storage capacity

摘要

This air conditioning system includes low pressure water vaporization, transfer and absorption, both in a solution concentrating section using solar radiation or other heat input and in a solution diluting section where heat exchange with ambient fan blown air subsequently permits cooling or heating enclosure air. The fan blown enclosure air is cooled or heated in passing through the same heat exchanger by changing the flow paths of the solutions passing to and from the two unique vapor exchangers, which are described in detail. The solutions are separated but contained in a sealed system with storage volume to give a large heat capacity potential by changing the solution concentration to either cool or heat the enclosure air.PP The various system operational modes are described in detail, with the functioning of the vapor exchangers and heat exchangers in concert with the flows through pipes and ducts as generated by pumps and fans together with control by valves.
