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. 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 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.
