  • Publication number: 20140000858
    Abstract: A thermostat method and apparatus has one or more demand circuits, an energy storage device; a DC regulator connected to the energy storage device, and a thermostat control connected to the DC regulator and to the energy storage device. Current is drawn from the one or more demand circuits when demand associated with the demand circuits is not active and the energy storage device is charged with the current drawn from the one or more demand circuits. If energy stored in the energy storage device is below the first predetermined threshold, activity in the thermostat is reduced and if energy stored in the energy storage device is above the second predetermined threshold, activity in the thermostat is allowed to increase.

  • Patent number: 8616270
    Abstract: An apparatus for the conditioning, storage and transportation of tennis balls. The tennis ball conditioning, storage, and transportation apparatus is used to condition tennis balls, primarily by heating to a desired operating temperature. Conditioning modifies the internal pressure of the balls and warms the composition of the balls to the desired playing temperature. The tennis ball conditioning, storage, and transportation apparatus includes a housing which may have handles and which has an interior which contains heating and/or cooling elements and which functions as a conditioning and storage chamber. The chamber is divided by a screen upon which the balls rest. A thermostatically controlled heater, cooler and fan achieve the desired temperature then stabilizes the balls at the desired temperature.

  • Patent number: 8561372
    Abstract: Thermally responsive walls can be formed of wall panels made from different materials and having staggered conduits with respect to each other when coupled together (e.g., pancaked or layered) to form a wall at one temperature. The staggered conduits in the different wall panels are configured such that they become aligned at a second temperature due to differences in expansion coefficients. The wall panels can be designed using a computing system that processes an algorithm that accounts for various parameters, such as the different thermal expansion coefficients.

  • Patent number: 8522859
    Abstract: A phase change material (PCM) heat exchanger device comprising heat exchanger cells (1a, 1b) operating on the regenerative countercurrent principle, one or more phase change material (PCM) accumulators (2, 3) provided in the heat exchanger cells and one or more vortex tubes (6, 7, 8). When the directions of the air, gas and liquid flows are cyclically reversed in the apparatus, energy is recovered into the heat exchanger cell and the PCM accumulator, and during the subsequent cycle, the energy is released from the heat exchanger cell and PCM accumulator. While one heat exchanger cell and PCM accumulator is being charged, the other heat exchanger cell and PCM accumulator is simultaneously discharged. Warm air exits a first outlet port while cold air exits a second outlet port of the one or more vortex tubes. The fluid flows heat or cool the heat exchanger cells and associated PCM accumulators.

    Abstract: Heat pumps that heat or cool a space and that also heat water, refrigerant management systems for such heat pumps, methods of managing refrigerant charge, and methods for heating and cooling a space and for heating water. Various embodiments deliver refrigerant gas to a heat exchanger that is not needed for transferring heat, drive liquid refrigerant out of that heat exchanger, isolate that heat exchanger against additional refrigerant flowing into it, and operate the heat pump while the heat exchanger is isolated. The heat exchanger can be isolated by closing an electronic expansion valve, actuating a refrigerant management valve, or both. Refrigerant charge can be controlled or adjusted by controlling how much liquid refrigerant is driven from the heat exchanger, by letting refrigerant back into the heat exchanger, or both. Heat pumps can be operated in different modes of operation, and segments of refrigerant conduit can be interconnected with various components.
