DE2725630A1 - Combined heating system for swimming pool water - has solar energy collector and biological heat source and conventional plant - Google Patents

Abstract

The collector for solar energy driven system is used for heating swimming pool water. The solar energy is collected by a collector and heat is transferred to the water. The water from swimming pool is recirculated through the solar energy collector. The heating system is combined with a biological heat source. The solar energy is collected by a lens assembly which tracks sun. The swimming pool water is pumped through this collector assembly. The solar heating system is linked with a biological heat generator. The latter is an underground silo tank for bacteria growth. This system incorporates also fuel oil or gas heating system.

Application areas

The patent application is shown individually according to the figure and has the following Generic terms:

Fig. 1 Collector for swimming pool water heating.

Fig. 2 Cross section and structural design of the collector.

Fig. 3 Bivalent heating system for the heating of swimming pool water with a collector in conjunction with a biomass.

Fig. 4 Bivalent heating system with gas or oil-fired central heating system, a heat pump and biomass as a secondary heat source.

Fig. 5 Bivalent system for domestic water heating via an electric, gas or oil-operated hot water storage tank, a heat pump and a biomass as a secondary heat source.

In Fig. 1 , an application of a collector "S" for swimming pool water heating is executed as an example.

The collector described with FIG. 2 serves as a heat source. The swimming pool water (12) is sucked off via a skimmer and fed to the circuit of the collector "S" via a circulating pump (14). Two slides (13) allow the proportional bypass setting. An automatic bypass control via a motor-controlled three-way valve is also conceivable. The connection of the water-connecting pipes to the pipe connection of the heat exchanger (3) of the collector is preferably established via flexible hose connections (9). This ensures that there is flexibility when changing the installation angle.

Construction of the collector "S" according to the sectional view in Fig. 2

Burning glasses (1) are used in a potting compound (2) with a selectively absorbing outer layer and an internal seal, as well as a heat-radiating layer or film (3) facing the blasting space. A U-shaped frame made of non-conductive material (plastic or similar) is used for stabilization and at the same time as a support for the overall construction (4). Lateral plates (6) - with the same properties as the casting compound described above - which are also lined on the inside with a foil and are so adjusted in height that the & tn ** d pU »te C Ό \ γ \ dependence on the focal length the burning glasses (1) can be arranged.

Ventilation openings (5) are used for venting the blasting space (13). The blasting plate (7) preferably has a weapon-shaped surface, which promotes the absorption of blasting. (more clearly drawn out in section C-D). Between dor A heat-conducting agent ("M) (contact paste) is preferably applied to the radiant plate (7) and the heat exchanger (θ) for better heat transfer. Underneath the heat exchanger (θ) there is a correspondingly thick insulating layer (9) a final plastic plate (10) connected to form a unit.

An additional angle profile construction connected to the U-frame allows the collector to be set up on a tripod Ball joint head, so that all-round rotation is guaranteed. See Fig. 1, so there is both manual and automatic tracking towards the sun.

In Fig. 3 , a bivalent heating system for heating swimming pool water with collector "S" in connection with a bio-mass is executed as an example.

Bio-mass (i), stored in a silo-like construction and provided with a bacterial feed device (3) with openings (2), is preferably embedded in the ground with a sufficiently dimensioned thermal insulation (4) against heat radiation.

The heat extracted from the bio-mass is transferred to a heat pump (5) fed into the swimming pool water circuit (θ). The connection with the arrangement described under Fig. 1 is preferably made via a temperature-controlled three-way valve (11), Via the circulation pump (7) and the return flow preventer (12).

In Fig. 4 , a bivalent heating system with gas or oil-fired central heating system, a heat pump and biomass as a secondary heat source is executed as an example.

Bio-mass (i), stored in a silo-like construction and with a bacteria supply device (3) is provided with openings (2), is sufficiently dimensioned to protect against heat radiation Thermal insulation (4) preferably embedded in the ground, the heat extracted from the bio-mass is transferred via a heat pump (5) the circuit of an oil or gas-fired central heating system fed. The admixture is controlled depending on the temperature via a weather-dependent control (15) with appropriate Temperature sensors (I7) + (18), which influence a motor-controlled three-way valve (19). This control allows a smooth adaptation of the heat sources (1) and (6) to the weather-dependent heat demand.

In Fig. 5 , a bivalent system for domestic water preparation via an electric, gas or oil-operated hot water storage tank, a heat pump and a biomass as a secondary heat source is shown as an example.

Bio-mass (1), stored in a silo-like construction and with a bacteria supply device (3) provided with openings (2), is preferably embedded in the ground with a sufficiently dimensioned thermal insulation (4) against heat radiation.

The heat extracted from the bio-mass is generated by a heat pump (3) fed to the storage tank of a water heating system. The hot water to be heated is analogously stored in a storage tank taken and circulated via a circulation pump (6) to transfer the thermal energy through the water pump (5). The control (θ) is controlled by a thermostat or flow rate
