  • Publication number: 20160169562
    Abstract: Disclosed is a method and device for a thermal energy storage liquid-suction heat exchanger (TES-LSHX) for air conditioning and refrigeration (AC/R) applications. The disclosed embodiments allow energy to be stored and aggregated over one period of time, and dispatched at a later period of time, to improve AC/R system efficiency during desired conditions. Not only are the benefits of LSHX stored and aggregated for later use, but when dispatched, the discharge rate can exceed the charge rate thereby further enhancing the benefit of demand reduction to utilities. The disclosed embodiments allow great flexibility and can be incorporated into OEM AC/R system designs, and/or bundled with condensing units or evaporator coils. These TES-LSHX systems can be retrofit with existing systems by installing the product at any point along the existing AC/R system's line set.
