Abstract

PURPOSE:To utilize even optical energy in a shortwave region of solar rays effectively, and to store energy for a prolonged term by heating a generator for an absorption type refrigerator by an optical-energy storing compound in a solar energy utilizing device. CONSTITUTION:Hot water mainly heated by the irradiation of long-wave rays in solar rays by a solar-ray collector 10 is stored in a hot-water storage tank 99 through a piping 86, and consumed through a hot-water supply piping 90 as required. On the other hand, a compound circulating collector section 16 receives shortwave rays in solar rays, and changes the optical-energy storing compound into a Q body (quadricyclene). The Q body is stored in a Q-body storage tank 38 through a feed pipe 36, but energy can be conserved for a prolonged term because the Q body does not return singly to an N body (norbornadiene). The Q body in the storage tank 38 is forwarded to the generator 44 for the absorption type refrigerator 12 in a feed piping 40 by a pump 42 as necessary, the generator 44 is heated by the heat of reaction through which the Q body returns to the N body by a catalyst device 54 in the generator, and a cooling piping 76 is cooled through a condenser 60 and an evaporator 56.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar energy cooling system that condenses solar energy and uses it for cooling. Conventional general cooling systems use compression refrigerators; In order to do this, it is necessary to convert hot water heated by solar energy into another energy such as electricity. On the other hand, when using an absorption refrigerator, hot water heated by sunlight is directly guided to a generator, and cooling is possible by heating the refrigerant gas to a high temperature.

However, since the heat storage material is water, a large amount of heat is radiated from the heat storage material hot water storage tank, making it impossible to store heat for a long period of time.

In addition, when heating hot water with a solar collector, the light energy in the long wavelength range of sunlight can be channeled relatively efficiently, and the light energy in the short wavelength range (0.17 to 0.35 μm) can be heated relatively efficiently. Taking into consideration the above fact, the inventive method of using solar energy with limited efficiency as it is not very efficient in generating heat, is to return light energy to a wide wavelength range from the sunlight. The purpose of this project is to obtain a solar energy cooling system that can store energy for a long period of time if necessary.

The solar energy utilization device according to the present invention converts a highly strainable compound into a high strain compound mainly by using light energy in a short wavelength range. A catalyst device installed in this supply pipe causes a catalytic thermal reaction in the highly strained compound, heats the generator, and vaporizes the refrigerant, making it possible to utilize light energy in the short wavelength range.

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

As shown in FIG. 1, in the solar energy cooling system according to this embodiment, solar energy collected by a solar collector 10 is guided to an absorption refrigerator 12 for cooling. This solar light collector 10 has a water circulation solar collector section 14 which also serves as a heat absorbing and dissipating material circulating sunlight heating means, and a collector section 16 which also serves as a light energy storage compound circulating sunlight converting means. (Hereinafter, they will be referred to as a water circulation collector section and a compound circulation collector section, respectively.) This solar collector 10 can have the shape of each building, but
In this embodiment, a specific structure shown in FIG. 2 is used as an example. This sunlight collector lO has a cylindrical body 2 whose upper end is open and which forms a plano-convex lens toward the opening of the nine-box body 18.
0 is fixed.

The plano-convex cross-sectional space 22 of this cylindrical body 20 corresponds to the compound circulation collector section 16 in FIG. communicated with the end. As a result, a plurality of plano-convex cross-sectional spaces 22 are connected to each other in series. An energy storage compound is distributed in this plano-convex cross-sectional space 22, and it absorbs light in the short wave boat range as a gong out of the sunlight irradiated in the direction of the arrow, and becomes highly distorted and becomes a barrel. It's about to change.

Inside the box body 18, a heat absorption tube 24 is arranged at a condensing part of sunlight passing through the cylinder body 20, and corresponds to the water circulation collector part 14 in Fig. 8g1. Therefore, the heat absorbing tube 24 absorbs mainly the long waves of sunlight that are not absorbed by the nine energy storage compounds in the plano-convex section space 22. The heat absorption tube 241 is provided with an auxiliary light absorption plate 26 in preparation for changes in the light condensing portion over time. It is preferable that these heat absorbing tubes 24 and the auxiliary light absorbing plate 26 have six directions as selective absorption surfaces. Further, the box body 18 is provided with a heat insulating material or the like to improve heat retention.

In this embodiment, norbornadiene (hereinafter referred to as N-form) shown in FIG. 3 is used as the optical energy storage compound flowing through the circulation pipe 34.

This N-form is a highly strainable compound that has fluidity at room temperature, and when irradiated with short wave light in the ultraviolet region, it changes into a highly strained compound quadricyclene (hereinafter referred to as 9-forms) through a photoisomerization reaction. When this Q-form is passed through a catalyst (cono(rutotetraphenylborifylline monolithic or cono-rutophthalocyani/complex)), it has the property of causing a catalytic thermal reaction and returning to the N-form state. At this time; 222
Kcm4/MoL = 240 caL/l Accompanied by simulated earthquake heat generation. Therefore, it is necessary to accumulate short tIL and long light as the king of sunlight! ! (= Can be released as thermal energy depending on the situation.

A heat exchanger 78 is provided by a pipe returning from the dilute solution 62 from the generator 44 to the dilute solution g62, and a portion of the dilute solution 68 in the generator 44 is communicated with the absorber 58 by an overflow pipe 80. Therefore, in this absorption refrigerator 12, The refrigerant gas generated in the evaporator 56 is absorbed by the dilute liquid while being cooled by the cooling water pipe 74, and as a result, a concentrated solution 62 is formed, which is sent by the pump 64 and the pipe 66, and is then absorbed by the heat exchanger 78. After being heated, it reaches the second generator 44. In this generator 44, it is further heated in the supply pipe 4G and becomes a refrigerant gas, and reaches the condenser 60. In this condenser 60, it is cooled in the cooling water pipe 74 and condensed. The condensed liquid 70 is evaporated in the evaporator 56 to remove heat of evaporation from the cold water pipe 76, and the cooled water in the cold water pipe 76 can perform air conditioning.

A supply pipe 86 from the black water circulation collector section 14 shown in FIG. 1 continues to a hot water storage tank 88.

This hot water storage 4W88 stores leakage water, which is a heat-absorbing material heated in the water circulation gorector part 14, and uses the hot water supply pipe 9 as necessary.
A water supply pipe 92 and a storage 441188 connected to a water supply source and an inlet of the water circulation collector section 14 are connected to the water supply source to supply the water 1 consumed in the hot water distribution system 9Q from this hot water storage tank 88.

Urine is drained into the water circulation collector section 14. This heat exchanger 100 heats nine bodies in the piping 40 with hot water from the water circulation collector section 14.
By this, consideration is given so that the heat generated in the generator 44 becomes high in the east.

A branch pipe 41 from the supply pipe 40 of the 9-body storage tank 38 is inserted into the storage tank 88 via a pump 43.
As in the case of the supply pipe 40, a catalyst device causes a pB medium maturation heat reaction that returns Oi from 9 bodies to 8 bodies in the hot water storage tank 88, making it possible to heat the hot water in the hot water storage tank 8B to the desired temperature. ing.

The 9 bodies in 38 are sent to the generator 44 of the absorption refrigerator 12 through the supply pipe 40 by a pump 42 as needed.In the generator 44, a catalytic reaction occurs in which the 9 bodies are converted to N bodies by a catalytic device 54. As a result, the generator 44 is heated and the refrigerant is separated from the concentrated solution and vaporized. This vaporized refrigerant is cooled in a condenser 60.
The liquid becomes a base liquid 70, which is evaporated in the evaporator 56 and cools the cold water pipe 76 by the heat of vaporization. This cold water performs air conditioning. Here, the nine bodies in the supply distribution f40 leading to the generator 644 are heated by the heat exchanger lOO due to the hot water heat of the branch distribution #98, so the heat generation efficiency in the generator 44 is high.
