Abstract: Disclosed is a system and method for providing power generation and distribution with on-site energy storage and power input controlled by a utility or a third party manager. The system allows a utility manager to decide and direct how energy is delivered to a customer on both sides of the power meter, while the customer directs and controls when and how much energy is needed. In the disclosed embodiments, the utility controls the supply (either transmitted or stored) and makes power decisions on a system that acts as a virtual power plant, while the end-user retains control of the on-site aggregated power consumption assets. The disclosed systems act to broker the needs of the utility and end-user by creating, managing and controlling the interface between these two entities.

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.

Abstract: Disclosed is a system and method for improving grid efficiency, reliability, security and capacity, utilizing energy storage over a plurality of on-site energy storing appliances, and also utilizing on-site demand reduction devices lacking storage, all controlled via configuration settings with a local means to act independently, yet in statistical coordination, to provide a desired effect. The appliance and controller are located on the downstream side of the end-users power meter, and facilitates the utilization of the stored energy and manages the optimal timing for producing and delivering the stored energy to the end-user. This model demonstrates a utility driven, disaggregated, distributed energy system, where the distributed energy resource is designed to behave as an offset to the predictable daily electrical demand profile.

Abstract: Disclosed is a method and device for a refrigerant-based thermal energy storage and cooling system with multiple condensing units utilizing a common evaporator coil. The disclosed embodiments provide a refrigerant-based ice storage system with increased reliability, lower cost components, and reduced power consumption and ease of installation.

Abstract: Disclosed is a method and device to efficiently regulate flow of refrigerant while maintaining a sealed chamber in systems providing stored thermal energy for use during peak electrical demand. A mixed-phase regulator replaces the thermostatic expansion valve used in conventional air-conditioning systems that, along with capillary tubes and orifices, regulates the refrigerant fed from the compressor to the heat load.

Abstract: Disclosed are a method and device for a refrigerant-based thermal storage system wherein a condensing unit and an ice-tank heat exchanger can be isolated through a second heat exchanger. The disclosed embodiments provide a refrigerant-based ice storage system with increased reliability, lower cost components, and reduced power consumption compared to non-isolated systems.

Abstract: Disclosed is a method and device to increase the cooling load that can be provided by a refrigerant-based thermal energy storage and cooling system with an improved arrangement of heat exchangers. This load increase is accomplished by circulating cold water surrounding a block of ice, used as the thermal energy storage medium, through a secondary heat exchanger where it condenses refrigerant vapor returning from a load. The refrigerant is then circulated through a primary heat exchanger within the block of ice where it is further cooled and condensed. This system is known as an internal/external melt system because the thermal energy, stored in the form of ice, is melted internally by a primary heat exchanger and externally by circulating cold water from the periphery of the block through a secondary heat exchanger.

Abstract: Disclosed is an apparatus that provides refrigerant based energy storage and cooling. When connected to a condensing unit, the system has the ability to store energy capacity during one time period and provide cooling from the stored energy during a second time period. The system requires minimal energy to operate during either time period, and only a fraction of the energy required to operate the system during the first time period is required to operate the system during the second time period using an optional refrigerant pump.
