As a result, the Q-substance is converted into an N-substance (a chemical compound capable of being highly distorted) and at the same time, heats additionally the hot water in the hot water storage tank 22.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar energy utilization device that collects and stores solar energy.

As shown in FIG. 1, in a conventional general solar energy utilization device, the dry water obtained in a collector 12 through which a water circulation pipe flows is guided to a hot water storage tank 14 for heat storage. A heater 16 is provided for this hot water storage tank 141c, and after heating the hot water according to IK, it is sent out 17 to the hot water supply section 18.

However, in such a solar energy utilization device, the heat radiation from the friend storage tank 14 whose heat storage material is water is large, making it impossible to store heat for a long time. 'In addition, this solar energy utilization device is capable of collecting light energy in the long wavelength range of sunlight relatively efficiently.
) The light energy is not very efficiently collected (heat is not collected and the efficiency of the heat collection part is limited).

In consideration of the above-mentioned facts, the present invention aims to obtain an energy utilization device capable of utilizing optical energy over a wider wavelength range of sunlight.

The solar energy utilization device* according to the present invention includes a circulating solar collector with heat absorption and radiation such as water that collects optical energy in the long wavelength range using Vi main and 12, and a highly strainable compound that is A circulating solar collector is provided to collect light energy over a wider wavelength range of sunlight, and both the heat absorbing material and the highly strained compound from these collectors are stored in a hot water storage tank. By introducing a heat medium into a storage container such as a heat exchanger, etc., and equipping this storage container with a catalyst that causes a thermal reaction by changing a high strain compound into a highly strainable compound, the storage container can be used to store both the heat absorbing and dissipating material and the original energy storage compound. It is designed to heat a heat medium such as hot water inside.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, in the solar energy utilization device according to this embodiment, a solar collector 20 is communicated with a hot water storage tank 22, which is a heat medium storage container installed in a plurality of pipes. This solar light collector 2o has a water circulation solar collector section 24 and a light energy storage compound circulation solar collector section 26 as heat absorbing and dissipating material circulating solar collectors 1 to 1. Hereinafter, they will be referred to as a water circulation collector section and a compound circulation collector section, respectively.

) This solar collector 20 may have the shape of each building, but in this embodiment, the specific structure shown in FIG. 3 is used as an example. To explain this structure in detail, a horizontal rotation shaft 71/-m 32 is fixed to an image vertical axis 30 which is pivoted to a fixed pace 28 installed on the roof of a structure (not shown), so that it can rotate together with the Taruyama axis. ing. A pair of brackets 34 are erected from this horizontally rotating foot 32.
A horizontal shaft 36 is pivotally supported on the horizontal shaft 36, and a vertical rotation frame 38 is fixed to this horizontal shaft 36 so that it can rotate together with the horizontal shaft.

The vertically rotating flunome 38 has a box shape with a transparent 7-lens prism 40 on the ceiling,
A plurality of circulation pipes 42, 44' are provided in the light collecting section. Here, the circulation pipe 42 corresponds to the water circulation collector section 24 in FIG. 2, and the circulation pipe 44 corresponds to the compound circulation collector section 26 in FIG. 2. This circulation pipe 44 is provided almost at the center of the light collecting section, and this circulation pipe 44
0-side sVc circulation/arm pipes 42 are arranged, water is circulated through the circulation pipe 42, and light energy storage compound is circulated through the circulation A pipe 44. The circulation nozzle 42 can be made into a double pipe if necessary, so that water can be circulated in the inner pipe and a vacuum can be created between the inner and outer pipes.

These two types of circulation A beams 42 and 44 are irradiated with sunlight that has passed through the Fresnel prism 40, but since sunlight has a different refractive index depending on the wavelength of the light component, light of different wavelengths is reflected in the circulation A beams 42 and 44. It is designed to irradiate Eve 42 and 44. In other words, sunlight passes through the Fresnel prism 40t and is refracted before being split into a spectrum, so a circulating nozzle 42° 44, which is a skin photoreceptor, is placed above the band-shaped portion of this dispersion spectrum that matches the wavelength range. The circulation pipe 44 receives short-wavelength light that is relatively largely refracted by the 7-Renel prism 40, and the water circulation pipe 42 receives long-wavelength light that is not relatively significantly refracted.

As a result, this sunlight collector 20 has a Fresnel prism 4
When the sun is -i'f at 0, it is possible to efficiently condense and separate light to collect light energy in the entire wavelength range.

Note that the vertical axis 30 and the horizontal axis 36 shown in FIG. A position sensor 1 anti-sunlight position storage device or the like can be used.

In this embodiment, norbornagene C (hereinafter referred to as N-form) shown in FIG. 4 is used as a light energy storage compound that circulates within the eve 44.

This N-form is a highly strainable substance that has fluidity at room temperature, and when irradiated with short wavelength light in the ultraviolet region, it changes into a highly strained compound quadricyclene (hereinafter referred to as 9-form) through a photoisomerization reaction. The properties are 1r and -C, and when these nine bodies are passed through a catalyst (conoltodetraphenylborifylline complex or cobalt phthalocyanine complex), a catalytic thermal reaction occurs and the nine bodies return to the N-form state. At this time 22”
at/'MI, 11. Accompanied by heat generation of -240 Ca'/'. Therefore, it is possible to store mainly short-wavelength light from the sunlight and release it as thermal energy if necessary.

Based on FIG. 2, the piping between the solar collector 20 and the hot water storage tank 22 will be explained. The water circulation collector section 24 is connected to the piping 46
The heat radiation coil 48 is arranged in the hot water storage tank 22 and is connected to the other end of the water circulation collector section 42 through a tube 50 at the other end. A pump 52 is provided in the middle of this piping 50, which guides the hot water heated by the water circulation collector part 24 to the hot water tank 22, and heats the hot water 54 in the hot water tank 22 through a heat dissipation coil 48. It has become.

- One end of the force ratio compound circulation collector section 26 is communicated via a pipe 56 with a three-way valve 58 to a pipe 60.62.

The piping 62 is connected to the Q-body storage tank 64. It is communicated via a pump 66 to one end of a heating coil 68 in the hot water storage tank 22 . The downstream end of this heating coil 68 is a pipe 69. N body storage tank 70
and communicates with the pipes 60 and 74 via a three-way valve 72. The heating coil 68 in the hot water storage tank 22 is provided with a catalyst 76 (a conomaltophthalocyanine complex is used in this embodiment) at its upstream end to cause a photoisomerization reaction in the nine bodies from the pipe 62. It's becoming a VC. This heat generating coil 68 is provided above the heat radiating coil 48.

Further, a companion pipe 74 connected to the three-way valve 72 is communicated with the other end of the compound circulation collector section 26 via a pump 78, and together with the pipes 56 and 60, constitutes the entire circulation path to the circulation pipe 44. In FIG. 2, in the piping between the solar collector 20 and the hot water storage tank 22, the broken line indicates the flow path for hot water, the solid line indicates the flow path for N bodies, and the dashed line indicates the flow path for nine bodies.

Further, a water supply power distribution 80 is connected to the lower part of the hot water storage tank 22 to send water from a water supply source (not shown) to the lower part of the hot water storage tank, and a hot water supply pipe 82 is connected to the upper part of the hot water storage tank 22 to supply heated hot water to the hot water supply section 8.

Thereafter, by switching the three-way valve 58 to connect the pipes 56 and 62, the nine highly strained compounds are stored in the nine-body storage tank 64. Since the nine bodies in the nine body storage tank 64 do not return to N bodies by themselves, there is no heat loss, and no heat insulating material is required, making it possible to store energy for a long period of time.

When necessary, the nine bodies in the nine body storage tank 64 are sent to the heating coil 68 in the hot water storage tank 22 by driving the pump 66. At the inlet of this heating coil 680, it contacts the catalyst 76 to cause a catalytic thermal reaction and return to the original 8 bodies, while also generating heat and exchanging heat with the hot water in the hot water tank 22 while flowing through the heating coil 68. The hot water inside is further heated. Therefore, the hot water supply section 84 of the hot water storage tank 22 not only uses the hot water heated by the heat radiation coil 48, but also uses the heat radiation coil 48 and the heat generating coil 68 as needed.
It is also possible to pump out hot water heated to high temperatures at both ends, making it usable for a wide range of hot water supply, air conditioning, and heating applications.

The light energy storage compound restored to 8 bodies by the heating coil 68 passes through the pipe 69 and is accumulated in the N-body storage tank 70, and if necessary, is circulated through the pipe 74 by switching the three-way valve 72 to the circulation/zeip 44. be returned.

Other compounds such as azepine can also be used.This azepine converts into dichlorobutenodihydrobyrol, a highly strained compound, when exposed to short wavelength light, and in the presence of a catalyst, it becomes highly strained iiJ again. As the gold compound reverts to azepine, it also generates heat.In the invention, it can also be used as a light energy storage compound in the form of kerosene, and can be applied to any liquid state as long as it has fluidity. be.

Although water pipes were used as the heat absorbing and dissipating material in the above embodiments, this is not limited to pure water, and may contain appropriate additives such as rust preventives and antifreeze agents. In addition to water, the heat absorbing and dissipating material may be any material that absorbs and releases sunlight energy as heat energy, and may be glycols, hydrocarbons, halogenated hydrocarbons, or the like. The storage@822 in the above embodiment is an example of a heat medium container, and when the heat medium is not directly consumed for drinking purposes but is used as a heat source for heating and cooling, etc., the heat absorbing and dissipating material flowing inside the solar collector 24 is As in the case above, fluids other than water may also be used.

In the above embodiment, Q body meter M tank 64. Although long-term storage of energy is possible by using a 7° N-body storage tank, the present invention is not limited to a storage tank, and any storage means that can substantially store the light energy compound may be used.
