Description
SOLAR ENERGY COMMUTATOR AND METHOD OF USE OF SOLAR ENERGY AS A SOURCE OF HEAT
The subject of the invention is a new solar energy commutator and a method of use of solar energy as a source of heat, mainly for room heating and supplying hot water installation.
There are known solar energy commutators being used as a source of heat for heating buildings and hot water boilers. Those commutators usually have a solid layer absorbing energy and liquid agent collecting heat.
The absorbing layer is usually a partition absorbing solar energy from solar rays being directed to it. The partition is solid or it is constructed of several movable elements, and its geometry allows regulation or optimization of an angle of incidence of solar rays. In case of the curtain partitions, the liquid agent is air. In case of commutators with solid partition, a heat working agent is usually a clean water. Commutators of such a known construction or analogous construction are known from Polish patent specification nos. 110826 and 174611, and from the Polish utility model specifications nos. 56683 and 56721 and patent applications nos. P-308066, P-310138, P-311376. The system of collecting heat from a solar commutator is described also in the Polish patent application no. P-308067.
Solar energy commutator for use as a source of heat, especially for heating rooms and supplying a hot water installation, according to the invention, is constructed of at least one panel consisting of, at least three compounded transparent plates. Between the plates there are chambers filled with various liquid agents, one of which is a liquid agent that absorbs solar energy and the other is a working agent collecting the absorbed heat.
According to the invention, each panel of the commutator consists of at least four plates combined with each other, and the third liquid agent is an insulation gas. The chamber which is filled with insulation gas has an outer, terminal position in relation to chambers filled with the liquid agent that absorbs the solar energy and the working agent that collects the absorbed heat.
According to the invention, each panel of commutator consists of five compounded plates and the insulating gas is a liquid agent in verge chambers.
The favourable insulation gas is the air at low pressure, not lower than 0,5 at.
According to the invention, the absorbing agent in the commutator's panels is preferably a coloured cooling substance based on glycol. The absorbing agent is preferably coloured black.
The plate dividing the chamber filled with the liquid absorbing agent and the outside chamber filled with insulation gas is also coloured and/or covered with impermeable absorbing layer.
Each panel is made of at least 3-layer polycarbon plate or several 2-layer polycarbon plates which are combined with one another.
In each panel, the chamber which is filled with the agent absorbing solar energy has connections with heat collecting system, with central heating system, especially floor heating system, whereas the chamber filled with the working agent collecting heat has an inlet and outlet and a shut-off valve.
The method of using solar energy as a source of heat, mainly for heating rooms and supplying the hot water installation, with a periodical collection of heat from solar energy commutator to heat collecting system, to central heating, floor heating in particular and/or hot water supply system, according to the invention is characterised by the fact that the solar energy commutator being a periodical source of heat, will automatically switch on when the return temperature in the central heating system is lower than the temperature in the solar energy commutator through a detector and electrovalve. This will allow warming up return system of central heating to the temperature similar to that of the absorbing agent . It will switch off when the temperature difference drops below 2 °C, whereas during the spring- summer season when temperature in rooms goes over 21°C, and temperatures in solar energy commutator are also higher, the basic source of heat supplying the central heating will be shut off, especially floor heating system, and the solar energy commutator will be used as the sole source of energy in this system.
In the method according to the invention, the system of floor heating collects heat from solar energy commutator in heat exchanger which is supplied with liquid agent absorbing solar energy, circulating in a closed circuit or a working agent collecting heat.
In the method according to the invention, solar energy commutator - which is, additionally or alternatively, used as a reservoir tank of hot water which plays the role of a working flow agent that collects heat - is supplied with water through water pressure
reducer to the pressure of 1 at in such a way that during hot water intake the open valve keeps up pressure in hot water collecting system in a building and, at the same time, the system will be able to remove water from the commutator in case of outdoor temperature drop below 2°C.
Additionally, according to the invention - when the temperature of water supplying a building goes below 3°C, heat will be collected from the solar energy commutator in order to warm up the temperature of supply water. The basic devices used to heat water in hot water installation are supplied with so-heated water.
According to the invention, in case of outdoor temperature rise over 25°C, the hot water installation in a building is directly supplied with water being a working agent collecting heat in a solar energy commutator.
The installation of using solar energy as a source of heat, especially for heating rooms and supplying hot water installation, including a solar energy commutator and heat collecting systems, according to the invention, is characterised by the fact that the solar energy commutator is made of at least one panel consisting of three combined, transparent plates, between which there are chambers filled with liquid agents - one of which is a liquid agent that absorbs solar energy and the other is a working agent that receives the absorbed heat. It has an open circuit of water supply being a working agent collecting heat and a closed circuit of liquid agent absorbing solar energy with a heat exchanger supplying central heating system, especially floor. It also has safety valves in both circuits, and a shut-off valve in the circuit of the working agent collecting heat.
In a closed circuit of an agent that absorbs solar energy there is an additional heat exchanger used to warm up water supplying the basic devices, which heat water in a hot water installation.
In the open circuit of a working agent collecting heat there is an additional heat exchanger, which supplies central heating system, especially for floor.
In a closed circuit of an agent absorbing solar energy, there is an additional air supply on the inlet to a solar energy commutator's panel. There is a deaerator installed behind the panel.
The commutator according to the invention consists of any number of panels, which makes it possible to locate the panels directly next to one another on the overall surface of the roof or any parts of a roof and directed in different world's directions.
Due to the use of the absorbing liquid agent the efficiency of the commutator changes significantly in comparison with other known commutators with solid absorbing layers. The commutator according to the invention efficiently absorbs a reflected light, which allows collecting energy also when the sunrays do not fall directly on the surface of the commutator.
The commutator, according to the invention, serves as a beneficial heat accumulator and an insulation layer of a roof.
In a preferred embodiment of the invention, where panels are made of five compounded plates, and the absorbing agent is not coloured black, the commutator according to the invention can be used as a dividing material, such as: a division wall in a house, winter garden or terrace roof, etc.
In case when the total surface of the commutator is 40 m2, the volume of the energy absorbing agent and the volume of heat collecting operational agent is about 240 1. The collector is both a great heat accumulator and the hot water reservoir tank.
The invention will be more precisely described with reference to the enclosed drawing, where Fig. 1 presents a single panel of solar energy commutator according to the invention, and in a cross-section along A-A line .

It has temperature detectors 13 in both circuits D.
In the closed circuit D there is a balance tank 14, a pump 15 and safety valve 16.
