Description

Method and device for heating rooms and of water consumed in these rooms

The invention relates to the heating of rooms and of service and / or heating water for these rooms.

It has already been proposed to condition rooms using heat pumps in which one Heat exchange between the atmosphere of these rooms and an external source, especially the external atmosphere, to heat these rooms in winter and to cool them in summer.

On the other hand, it was also proposed, at least in part, the rooms with the help of solar cells, which in the Facade of a housing are arranged to be heated and at the same time with the heat pumps at least one To use part of the warmth of the air, which has to be dissipated for the renewal of the atmosphere.

The measure according to the invention is intended to propose an arrangement in which the known heating devices can be combined in such a way that their efficiency is increased and the installed power is effectively increased can be reduced. Here, the fresh air entering the rooms becomes thermal as soon as it is passed built-in storage cells, which are provided in the roof or facade, heated while the consumed the air drawn off for the purpose of evacuation sweeps past the evaporator of a heat pump in order to remove it To give off heat in favor of a circuit that is used for heating the rooms and / or the domestic water to be used serves. This circuit absorbs at least some of its calories on the condenser of this heat pump.

The absorber advantageously forms the front of a storage body or a storage chamber, which is a Substance of high heat capacity, such as glycolized water or preferably aqueous gel, in particular acrylic gel, and the fresh air entering the rooms brushes the walls (Water wall).

It is preferably possible to lead some of the air out of these spaces in such a way that it is also in contact heated with the body of the solar cell before it is reintroduced into the rooms. In this case it is preferred that fresh air come into contact with the absorber, the air of the rooms at the rear of the cell warmed up. According to the invention comprises an advantageous device for conditioning the rooms and for heating of the domestic water in these rooms at least: a solar cell with integrated storage, which is arranged in the facade of the rooms; Facilities for feeding the rooms with fresh air that these Fresh air in direct contact with the cell's absorber; and / or rear walls of the heat storage chamber, which are arranged behind it, lead; a heat pump; Facilities for discharging the used Air from the rooms, this stale air being brought into contact with the evaporator of the heat pump and a heating circuit for these rooms and / or the domestic water in which the water is in contact comes with the condenser of the heat pump, the circuit advantageously with complementary heating devices is equipped, which are arranged in the flow direction behind the heat exchanger surface.

As already mentioned, the device optionally includes means to remove any part of the air the spaces in contact with the cell's absorber or

to lead the rear walls of their storage chamber and to return this air to the rooms in the circuit and, of course, facilities for solar heating of the rooms when the temperature requires it, especially in summer.

Such an arrangement makes it possible to operate the cells at a low temperature and thereby store heat to get, which compensates for the fluctuations over the day, while the with more uniform Temperature-fed pump works with relatively small and practically constant temperature deviations.

So there is a significant advantage because it becomes possible in a simple and yet optimal way to use the solar energy generated by the solar cells. The invention is particularly suitable for Conditioning of rooms of moderate volume, single houses or multi-family houses of medium size Size.

The measure according to the invention therefore makes it possible to condition the rooms and the domestic water To heat the rooms with the help of solar cells, the outer surface of which is considerably smaller than that that would be necessary if no heat pump were used to heat the consumed leaving the rooms To withdraw air.

This results in considerable savings in units, especially in living spaces.

For example, embodiments of the invention are intended now with reference to the accompanying drawings

explained. These show in

1 shows a schematic representation of a conditioning arrangement for air and service water according to the invention;

Fig. 2 in a larger representation, the solar cell and the Heat storage chamber (water wall) with which it is equipped;

Figures 3 and 4 are schematic representations of the arrangement the two half-shells that form the heat storage chamber;

Fig. 5 is a plan view of a preferred embodiment of this chamber;

and FIGS. 6 and 7 are schematic sections, vertical along the line VI-VI and horizontally along the line VII-ViI in FIG. 5.

Fig. 1 shows a house 1, the facade of which is provided with double glazing 2, in front of which a protective curtain 3 can be lowered and behind which there is a surface 4 which absorbs solar radiation (Absorber); the latter is in thermal contact with a chamber 5. for heat storage (water wall), which is formed by connected water storage 6. A counter wall 7 made of a thermally insulating Material separates the chamber 5 from the spaces 8 that are to be heated.

Outside air enters at 9 at the base of the double glazing 2, circulates between it and the water wall 5 and heats up in contact with the absorber 4 and penetrates into the space 8 at 10.

A part of the air within the space 8 also heats up in contact with the water wall 5 during passage at 11 at the base of the opposite wall 7 and is

into the room 10 in the upper part of this opposite wall after mixing with fresh air at the outlet from the cell reintroduced. The opening 11 is preferably with provided with a flap 11a which allows the functioning of the cells as a function of the atmospheric To change conditions; a flap 11b also allows fresh air to be directed towards the rear of the cell give when the flap 11a is closed. The opening itself carries a flap 10a that allows the Turn off the heating in the room.

A heat pump 12 with a compressor 13, a Evaporator 14 and a condenser 15 is arranged such that the withdrawn from the space 8 to the outside Used air (arrow F) sweeps past the evaporator 14 and gives it off some of the heat while a hot water circuit 16 takes at least part of its heat from the condenser 15. This hot water circuit feeds, for example, as shown, heating radiators 17, a hot water balloon 18 and a heat exchanger 19, which is intended to heat domestic hot water; he is also equipped with additional heaters 20, 21 provided.

The water wall 5 can be constructed in a manner known per se. However, it can be advantageous, like the figures 4 and 4 show that each water reservoir 6 has two half-shells 6a and 6a connected to one another via a flat surface 6b, the latter being parallel to the outer surfaces of the memory (Fig. 3) or obliquely with respect to this (Fig. 4) can be arranged so as to have good mechanical strength.

According to another embodiment of the invention (FIGS. 5, 6 and T) , the different reservoirs 6 can also be made from a single component, the surfaces of which alternatively have planar parts 22, 23 and re-entrant parts 24, 25 which form circumferential ribs. These serve to provide a favorable resistance to hydrostatic pressure.

Such memory can be made of a plastic thermoformable or made in the thermosetting material. A front surface can the Form absorber 4 and for this purpose a color suitable for absorbing the radiation, for example black, exhibit.

The measure according to the invention is used to heat rooms and a hot water circuit simple, inexpensive and easy to implement arrangement proposed by the usual means.
