Abstract: A hybrid heat pump system comprising a heat pump loop integrated with a hydronic loop. The hybrid heat pump system offers multiple modes of operation to provide increased versatility and improved performance. Each of the loops can operate independently. In addition, the loops can operate in conjunction with each other in both heating and cooling modes. Still further, the hydronic loop can provide a reheat function when the heat pump loop is operating in the cooling mode to provide improved dehumidification of the air delivered to the conditioned space. The heat pump loop may include a hot gas bypass functionality for capacity control and/or freeze protection. The hydronic heat exchanger and the space heat exchanger of the heat pump loop may be combined in a compact single slab construction with a slit fin preventing cross-conduction between the heat exchanger sections.

Heat insulation is disposed below the metal sheet. At least one hot air duct and at least one cold air duct are each formed parallel to a rafter direction and in the plane of the roof panel. Each hot air duct is exposed to a surface of the metal sheet, and each cold air duct is encompassed by the heat insulation. A medium collectively fills the air ducts. A lower air reversing chamber is formed at a lower end portion of the roof panel, and an upper air reversing chamber is formed at an upper end portion of the roof panel. A cooling device is disposed in the upper air reversing chamber.

Abstract: A receiver module for a solar power station receiver, including a metal structure and an absorber module, the metal structure defining a cavity extending along a longitudinal axis in a base of which the absorber module is housed. The cavity includes an aperture configured to be aligned towards at least one mirror of the solar power station, the aperture is edged by two side portions of the metal structure extending longitudinally on either side of the cavity. The receiver module also includes thermocouples positioned on each of the side portions relative to the longitudinal axis to detect a temperature difference between a reference temperature and two points of the metal structure that are opposite relative to the longitudinal axis.

Abstract: A solar panel comprises a conduit which in the usual way is designed to comprise a heat carrying medium for heat transfer between the solar panel and the surrounding environment. The conduit is placed so that it can be heated by the rays from the sun. The solar panel comprises a chemical heat pump of the type hermetically sealed unity tube with a reactor part, an evaporator/condenser part and a passage there between. The part of the unity tube comprising the reactor part of the chemical heat pump is positioned in heat conducting contact with the first conduit and thereby the part of the unity tube with the reactor part will be heated. The unity tube may be surrounded by a heat insulating part of vacuum jug type comprising an evacuated space between an outer wall and an inner wall. The inner wall may at its outwards facing surface comprise a radiation receiving part adapted to transform solar radiation to heat and which is in heat conducting contact with the first area and the first conduit.

Abstract: A furnace in combination with a heat pump and solar panels for providing domestic hot water and forced hot or cooled air utilizing heat pump achieved efficiency levels in an on-demand and unlimited domestic hot water, heating and air conditioning system. In heating mode, recycled air acquires heat from the heat pump's condenser coil and transfers this heat to the on-demand hot water.

Abstract: The present invention is a self-contained, solar powered heating and cooling system for a building. The collector has an insulated heating chamber, and a light transmissive cover and a thermostatically controlled vent. The chamber contains absorptive columns standing on the floor. An internal liquid conduit exposes the liquid to the heat within the chamber. The collector is connected to a remote thermal reservoir such that a liquid circuit and a separate gas circuit both circulate heated fluid to the reservoir. Heat can be stored in any of a liquid reservoir, thermal mass reservoir and gas reservoir. Wind powered generators and photovoltaic cells provide power for the system or other applications. The thermal reservoir has heat exchangers which deliver stored heat to the building or operate a heat operated refrigeration machine (e.g., a liquid absorption chiller). Additional self sustaining power sources may optionally be incorporated into the present invention.
