Title: Automation and control of solar air conditioning systems

Abstract

A solar powered air conditioning system includes an absorption machine coupled to three primary loops. A heat loop provides energy to the absorption machine. A cooling tower loop exhausts heat from the absorption machine. A chilled water loop is used to draw heat from a room or building. The heat loop provides energy from a boiler and/or from a number of solar collectors. In one mode of operation, the solar collectors circulate through a storage tank. The flow through the solar collectors is regulated to maximize energy collection.
