Abstract: A first heat exchanger, a desiccant block, and a second heat exchanger are arranged in series. In a dehumidifying operation, a first operation mode and a second operation mode are alternately repeated. In the first operation mode, the first heat exchanger is operated as a condensor or a radiator and the second heat exchanger is operated as an evaporator. In the second operation mode, the first heat exchanger is operated as the evaporator and the second heat exchanger is operated as the condensor or radiator. A pressure reducing amount in the first operation mode is controlled to be smaller than in the second operation mode so that a degree of superheat in the evaporator (second heat exchanger in the first operation mode, first heat exchanger in the second operation mode) in each of the first operation mode and the second operation mode is appropriately controlled to increase a dehumidifying amount.

Abstract: A method for improving the efficiency of a solar heating system based on absorbing heat from solar radiation into the outer surface of a concrete wall. The heat transfer device makes use of a fluid in a tube system to transfer heat from the outside of the wall to the inside of the wall. The inside wall is then used to heat air that is passed over it, and that air is then used to heat up a heat storage system.

The conduit module includes four three-way valves to communicated fluid from and to the fluid circuits to first and second heat exchangers in the heating/cooling module. The first heat exchanger is used to heat a fluid flow and the second one chills a second fluid flow. The conduit module simultaneously supplies a hot fluid flow to a hot fluid circuit and a cold fluid to a cold fluid circuit. The source fluid is routed by the conduit module. A method of circulating fluid is also disclosed.

Abstract: This relates to a heating device including a solar energy collector, the solar energy collector transferring collected solar energy to outside air. First collector panels are used to heat outside air which heated air is led to a heater, for example a space heater. Second collector panels are used to transfer solar energy to air led to a heat exchanger of a heat pump. The heat pump transfers the extracted heat to heat storage. The stored heat is added to the air coming from the first collector panels if the temperature of the air coming from the first collector panels is below a predetermined temperature.

Abstract: A dual hybrid heating apparatus, method of assembly and operation to pre-heat vaporizable fluid by free heat sources—waste heat from heat recovery units and insolation. The pre-heated vaporizable fluid is routed to where a parabolic dish solar concentrator vaporizes it to turn a blade of a turbine generator to generate electricity. Heat is extracted from the vapor to form condensate, but the vapor also heats the condensate before being cooled by heat exchange with fluid cooled by a cooling tower.

Abstract: One embodiment of the invention is a thermosiphon vessel for storing seasonal environment energy in the ground. The thermosiphon includes: a fluid vessel comprising a heat exchange tube, configured to contain a working fluid, and further configured to receive a fluid inlet and a fluid outlet; a wicking material arranged within the fluid vessel and configured to retain liquid-state working fluid substantially adjacent an inner wall of the heat exchange tube; a fluid level sensor arranged within the fluid vessel and configured to determine the level of liquid-state working fluid therein; and a pump arranged within the fluid vessel and configured to maintain the level of liquid-state working fluid below a threshold level within the fluid vessel. The pump is operable between an energy capture mode to absorb thermal energy from an above-ground heat source and an energy release mode to release thermal energy to an above-ground heat sink.

The outputting end of the two or more heating stages constituted by the solar energy collector or by the collector and the heat pump is connected through ducts to the corresponding water-heating tanks. A predetermined amount of produced water heated at multiple stages is respectively stored in the water-heating tanks.

Abstract: An integrated heating and cooling system for a living space of a building connects together (a) a solar-based heating and cooling system and (b) heating and cooling systems that rely directly or indirectly on fossil fuels that are conventionally used in buildings. The system operates the solar-based heating and cooling system preferentially to heat or cool the living space. Therefore, the system minimises the use of fossil fuels to heat and cool the living space.

Abstract: Heat dissipating apparatus or system for dissipating heat generated by a payload on a spacecraft having a plurality of surfaces. The system includes at least one radiator-condenser coupled to one or more of the surfaces of the spacecraft and a heat pump including an evaporator, a compressor, and an expansion valve coupled in a closed-loop manner to the radiator-condenser. The system components are coupled together using small diameter, thin- and smooth-walled tubing. The system enables the radiator-condenser to be elevated above the source or payload temperature, and, along with the use of thin walled tubing, reduces the mass of the spacecraft. Because the radiator-condenser temperatures are elevated, multiple surfaces of the spacecraft (west, east, earth and aft) can be effectively used as radiating surfaces.

Abstract: A solar energy collector system for reducing heating, air conditioning and power consumption of a building structure. The solar energy collector system includes a housing structure, a collector plate, an insulating sheet positioned between the collector plate and a floor of the housing structure, a thermopile unit within the housing structure, and a fluid positioned below the collector plate. The fluid adjacent the collector plate is heated thereby rising to an upper portion of the housing structure and thermally conducting the thermopile unit for generating electricity. The cooled fluid then passes downwardly below the insulating sheet to a lower portion of the housing structure. A heat exchanger is utilized upon the opposite side of the thermopile unit for transferring the heat to a desired location within or outside of the building structure.
