Abstract
An improvement in an absorption refrigeration and/or heating system including apparatus (157) to convert the pressure energy and/or phase change energy in the solution and/or refrigerant of the absorption system into mechanical energy, with additional apparatus to replace or supplement the externally supplied mechanical energy motive device (152) in the system with the converted mechanical energy. The system includes a first positive displacement pump (98) for conveying the absorbent solution from the absorber to the generator with first positive displacement apparatus (98) driven by a motive device (152) that is activated by the externally supplied energy. A second pump (158) is provided that is driven by the system pressure energy. Each of the pumping apparatus is being independently driven and connected to the other only by fluid connection.
