A SOLAR TRACKER FOR THERMAL AND PHOTOVOLTAIC PANELS WITH A FORCED AIR SYSTEM, APPLICABLE TO BUILDINGS, with a "panel-carrying framework on a dome, whose interior features a heat accumulator, acting as a column; attached to the base of this there is a fan and radiator capable of blowing treated air towards the apartments, it being installed over the stairvvell, which acts as a carriage duct, also acting as a fire protection system as it creates centrifugal radial flows, expelling harmful gases on opening doors and windows. The framework tilts on two axes of a spider joint located between two yokes, one of these fixed on the column and the other tilting, this last supporting the framework. Four servo-cylinders, two per axis, cause it to be directed towards the sun. The rows of the framework, arranged on different levels, in the shape of a stepped pyramid, support juxtaposed thermal and photovoltaic panels, it being possible to direct those appropriate towards the sun while the others are shaded.

A hot water circulation heating system performs heating by causing hot water to circulate and comprises: a tank (40) that stores the hot water; a room radiator; an indoor heating-use circulation pump (51) that causes the hot water to flow from the tank (40) to the room radiator and returns the hot water back to the tank (40); a heat pump (10) that heats the hot water; and a hot water heating-use circulation pump (25). The hot water heating-use circulation pump (25) causes the hot water to flow from the tank (40) to the heat pump (10) and returns the hot water back to the tank (40). The heat pump (10) includes a compressor (11), a radiator (12), an expansion valve (13) and an evaporator (14) and heats the hot water by heat emitted from the radiator (12).

摘要:
In a heat pump water heater, a water-cooling heat exchanger is comprised for preliminarily cooling water, that flows into a water-heating heat exchanger for heating the water by a heat exchange with a refrigerant, by performing a heat exchange with a refrigerant, to prevent water from freezing in the water-cooling heat exchanger. A refrigerant temperature sensor 13 for detecting the temperature of the refrigerant discharged from a water-heating heat exchanger 3, and a water-cooling heat exchanger 5 for performing the heat exchange between the refrigerant flowing from an expander 15 toward a compressor 11 and the water supplied from a storage tank 4 are comprised, so that the flow amount of the refrigerant toward the water-cooling heat exchanger 5 is adjusted on the basis of the refrigerant temperature detected by the refrigerant temperature sensor 13. For example, the expander 15 is closed when the temperature detected by the refrigerant temperature sensor 13 is lower than a prescribed temperature.

A heat source unit (1) includes a compressor (11), an electronic expansion valve (13), a heat-source-side heat exchanger (14), an outdoor blower (F), and a controller (30) for electric devices. A hydrothermal exchange unit (2) accommodates water heat exchangers (15, 16), water pipes (6), pumps (21, 22) and a controller (9), and is connected to the heat source unit (1) via refrigerating pipes (7) and electric wiring (8). A tank unit (3) has tanks (4, 5) for storing hot water obtained as a result of heat exchange by the water heat exchangers (15, 16). The hydrothermal exchange unit 2 has a housing (2A). The front, rear, upper, left and right sides of the housing are covered with panels. A bottom plate (45) for the housing is disposed predetermined distance above the lower end of the housing. The housing accommodates the hydrothermal exchange unit (2), and a space below the bottom plate of the housing accommodates connectors (6a to 6d, and 7a, 7b) for the water pipes (6) and refrigerant pipes (7). This completely prevents freezing of the water pipes (6), makes use-side units compact, and improves operation efficiency.
摘要:
A system for utilization of renewable energy resources and/or recovery of energy, comprising a multifunctional unit, which includes a water heater (1), and a heat pump (2). The heat pump is adapted to transfer heat and/or provide cooling to water in the water heater (1).

The second tank (4) is in heat exchange with a second circuit in the heat pump which is adapted to heat water in the second tank (4) to a second temperature level, which is lower than the first temperature level, or to cool down or freeze water in the second tank (4).
摘要:
The invention relates to a heat accumulator having at least one first volume and one second volume. Said volumes are separate, can be respectively filled with, or passed through, by a medium, and are in, or can be brought into, thermal contact. The invention is characterised in that another volume that can be filled with a fluid and emptied, a so-called switchable volume, is provided between at least the first and second volumes, said switchable volume being in thermal contact with the media of the first and second volumes.
