Abstract: A dynamic system controls indoor relative humidity and temperature to achieve specified conditions by applying multiple stages of dehumidification. In addition to a stage that increases dehumidification by reducing the speed of the indoor blower, the system uses a reheat coil and multiple valves that allow the reheat coil to function as either a subcooling coil or a partial condenser. Thus the system can maintain specified indoor temperature and humidity conditions even at times when no heating or cooling is needed. The system may have an outdoor condensing unit including a compressor and a condenser operably connected via refrigerant lines to an indoor unit to form a “split system” refrigerant loop.

Abstract: A method of forming an insulated concrete foundation is provided comprising constructing a foundation frame, the frame comprising an insulating form having an opening, inserting a pocket former into the opening; placing concrete inside the foundation frame; and removing the pocket former after the placed concrete has set, wherein the concrete forms a pocket in the placed concrete that is accessible through the opening. The method may further comprise sealing the opening by placing a sealing plug or sealing material in the opening. A system for forming an insulated concrete foundation is provided comprising a plurality of interconnected insulating forms, the insulating forms having a rigid outer member protecting and encasing an insulating material, and at least one gripping lip extending outwardly from the outer member to provide a pest barrier. At least one insulating form has an opening into which a removable pocket former is inserted.

Abstract: A rapidly assembled pre-fabricated array of heating elements, such as tubing or wire, on a rigid mesh, for use in radiant panel heating and/or cooling systems, reduce costs by streamlining both the design layouts and the labor operations to fabricate and install the systems. The pre-fabricated arrays may be installed with the mesh on the finish floor side for additional protection of the heating elements during and after installation.

Abstract: A dynamic system controls indoor relative humidity and temperature to achieve specified conditions by applying multiple stages of dehumidification. In addition to an optional stage that increases dehumidification by reducing the speed of the indoor blower, the system uses a reheat coil and multiple valves that allow the reheat coil to function as either a subcooling coil or a partial condenser. Thus the system can maintain specified indoor temperature and humidity conditions even at times when no heating or cooling is needed.

Abstract: A combined refrigerator-water heating system providing one or more insulated food storage compartments, includes an insulated water storage compartment, a refrigeration system including a compressor, an evaporation heat exchanger configured to cool the food storage compartment(s), a condenser configured to heat the water storage compartment, a flow restriction/expansion device, piping connecting the compressor, condenser, expansion device and evaporation in a series flow loop, a resistance electric heating element configured to heat the water storage compartment, and a control means to activate the compressor in response to cooling demand from the food storage compartment, and to activate the electric heating element in response to either heating demand from the water storage compartment or a time-of-day signal to bias resistance electric water heating operation toward times of off-peak electric use.

Abstract: A refrigeration-coupled thermal energy storage control system includes apparatus and methodology for establishing target cooling and heating storage conditions, and selecting between cooling and heating modes, based upon outdoor temperature history, and for operating the system until the target storage conditions are achieved. In the cooling mode, cooling storage quantity increases with increases in outdoor temperature, and in the heating mode heating storage quantity increases with decreases in outdoor temperature. The system further includes apparatus and methodology for biasing operation of cooling, heating and domestic hot water production modes during off-peak periods, rather than during one-peak periods. The system incorporates logic for fan coil pump seasonal interlocking, outdoor heat exchanger fan operation, outdoor heat exchanger coil defrosting, and compressor crankcase heater operation.
