Abstract
A Step Flow control device and methods therefore provide instructions to control operation of various absorption chiller components based on measured load or temperature information. Operating an absorption chiller according to Step Flow balances the flow of heat energy through the absorption chiller to increase efficiency and prevent crystallization. The control device may be integrated into various components of an absorption chiller or may be remote therefrom. In this manner, Step Flow can be used in new absorption chiller installations or be used to retrofit existing installations.
