Abstract

PURPOSE:To provide the titled system adapted to heat or cool an air even at the shortage in an insolation energy, by arranging such that when there is an ample insolation energy, the heat and electricity of solar ray are taken out simultaneously for their respective purposes of heating and cooling, while a surplus electricity is utilized to generate a hydrogen inside an electrolytic tank for its storage, and when an insolation energy becomes shortage the stored hydrogen is utilized to drive a fuel cell for generating an electricity which may be used for the cooling operation, or burnt by a hydrogen boiler for generating a heat which may be used for the heating operation. CONSTITUTION:An electricity obtained by a solar battery 55 is conductive to an anode and a cathode inside an electrolytic tank 39 for generating an oxygen and a hydrogen at the anode and the cathode respectively. The hydrogen thus generated is subject to a compression by means of a hydrogen compressor 44 and raised its pressure for storage inside a hydrogen tank 41. To operate the system in a cooling mode during a summer season, the hydrogen compressed and stored inside the hydrogen tank 41 is caused to release its pressure by means of a pressure reducing valve 50 and guided into a fuel battery 46 through a three-way valve 47 adapted to switchover the replenishment of hydrogen, while an oxygen of oxygen tank 42 or an atmospheric air (oxygen) is introduced as the oxidizing agent thereof into the fuel battery wherein an electric power generation is performed. The electricity thus generated is introduced into a DC compressor 38 for driving a steam compression refrigerator which may produce a cold water for use in a cooling operation. To operate the system in a heating mode during a winter season, a hot water is converted into a thermal energy inside a heat accumulative tank 2 by means of a hybrid collector 37 and used to heat the air.

様、補助のエネルギーが必要上なる。In addition to this, there are also air-conditioning and hot-water supply systems that utilize solar energy and desiccant air-conditioning and heating systems that use adsorbents such as silica gel and zeolite. Since it has a heat storage tank, even on days when there is no sunlight, heating and cooling can be performed using the thermal energy stored in the heat storage tank. However, if there is no sunlight for several days, it becomes necessary to perform heating and cooling, and the temperature of the heat storage tank becomes lower than the ambient temperature. Due to the heat dissipation caused by the high temperature, the temperature of the hot water in the heat storage tank decreases, and heating and cooling cannot be performed using the stored energy alone, so supplementary energy is inevitably required. Also in the example shown in FIG. 3, even if surplus power from the solar cells is stored in the storage battery, cooling will no longer be possible within a few days due to air conditioning and self-discharge of the storage battery. Also, in heating, as with other systems, supplementary energy is required.

ギーを貯蔵することができないため、実現困難である。Furthermore, the energy load on air conditioning, heating, and hot water systems is unevenly distributed between summer cooling and winter heating, and in the middle of spring and autumn, only hot water is used, and the collected solar energy is left over. Even if a shift is considered, it would be difficult to implement because conventional systems cannot store energy for a long period of time as described above.

行うものといえる。Considering this system 0IIL, excluding hot water supply, it can be said that it performs cooling operation in summer, heating operation in winter, and energy storage operation in the intermediate period.

まず、中間期のエネルギー貯蔵運転について説明する。First, energy storage operation during the intermediate period will be explained.

ギー貯蔵運転を停止し１、水素の発生を止める。Water is sent to the water purification device side by the water supply pump (43) to become pure water, and the purified water is passed through the heat storage tank (2) by the three-way valve 09 for temperature adjustment before being sent to the electrolytic tank 09). Divide the heat storage tank (2) into a bypass type, and fill the electrolytic tank 01) with pure water [1 temperature and specified humidity (approximately 70°C) K
Adjust. The reason why the temperature of pure water is lowered in this way is because the electrolytic operation described later improves power efficiency when the distillate temperature is high, and the temperature of the hot water in the heat storage tank (2) is low and does not reach the specified temperature. That's fine, though. The pure water enters the electrolytic tank 09) and becomes an electrolyte. The wiring switching switch (connects to the electrolytic tank 41!j side and does not connect to the DC compressor (support) side). Since the electricity obtained from the solar cell is connected to the @ pole and cathode of the electrolytic tank hook, oxygen is generated on the anode side and hydrogen is generated on the cathode side. The generated hydrogen is compressed by a hydrogen compressor (441) to high pressure, and is then transferred to a hydrogen tank (441).
It can be stored in 11. On the other hand, oxygen is stored in an oxygen tank (42I) without being compressed. This is because the fuel cell can operate on oxygen in the air, so there is no need to store the entire amount of oxygen. However, it is not necessary to install an oxygen tank (on top of the tank) and store it at all. However, it is also possible to store a large amount of hydrogen by installing a compressor. When (41) is satisfied, the energy storage operation is immediately stopped and hydrogen generation is stopped.

。When there is a cooling load, but there is no sunlight and the solar cells cannot provide the necessary electrical output for cooling (this can be known because the voltage is below a specified level, etc.), the hydrogen tank (411) stores hydrogen. The compressed hydrogen is depressurized by the pressure reducing valve (7), and is led to the fuel cell (461K) through a three-way hydrogen replenishment switching valve (461K). Air (oxygen in the air)
is guided to the fuel cell, which generates electricity. The electricity generated in this way is led to a DC compressor @ to drive a vapor compression refrigerator, producing chilled water and performing air conditioning. When the cold water in the hot and cold water tank (7) is at a temperature that allows sufficient cooling without driving the refrigerator, and when there is sunlight, the refrigerator stops and the cold water in the hot and cold water tank (7) is turned off. Cooling operation and energy storage operation are carried out.
