Description

The present invention mainly uses a high-temperature solar collector as a heat source for air conditioning and heat storage liquid tanks, combined with an electric heater in a wind power generator, and installed a blower pipe and a liquid flowing liquid pipe in the heat storage liquid tank, By changing the temperature of this thermal storage liquid tank and increasing / decreasing the amount of liquid in this tank, the high temperature to low temperature usage range is large, the use of commercial power is suppressed, and the installation is easy to install. The present invention relates to a multi-purpose heat storage device using both a heater and an electric heater.

Conventionally, a device that collects sunlight has been used as a solar water heater on the roofs of private houses, and recently it can be used for hot water such as bathing and cooking, floor heating, and snow melting. It is quite popular as an effective use of solar heat.

Particularly in recent years, from the viewpoint that the use of natural energy is indispensable for preventing global warming, various solar heat collecting materials have been developed, glass tubes, aluminum pipe types, and vacuum glass pipe types have also been developed. The photothermal type is used not only for water heaters but also for power generation.

These solar heat collectors are still unstable and the efficiency of solar heat utilization has not been determined, and the price is too expensive.

In particular, companies and universities around the world are studying various methods to improve the use of renewable energy. However, it is possible to use more than 50% of natural energy alone throughout the year with one kind of method, and it is inexpensive and private. There are no devices that can be used for multipurpose purposes other than household water heaters.

In recent years, disasters such as wind and rain caused by abnormal increases in oil prices and abnormal weather due to global warming have spread throughout the world, and the use of natural energy as a solution to this change. Improvement is an urgent need.

Among them, in particular, wind power generation and solar power generation are mainstream, and the improvement of the use of solar heat has been particularly active recently.

As for wind power generation, the increase in size is a problem of secondary environment destruction due to wind direction and noise generation, the installation site is decreasing, and solar power generation also has problems such as high cost and increased power generation efficiency However, it still takes time to disseminate, and the actual situation is that the use of solar heat has not reached 10 to 12% of the amount of heat.

In general, the majority of households use electricity and gas for air conditioning, cooking, and hot water supply such as baths. If we can establish a method to cover this with renewable natural energy throughout the year, Since the consumption can be suppressed and the emission of CO2 can be considerably reduced, it is desired to develop a cooling / heating device using natural energy.

Against this background, development of a hybrid multipurpose heat storage device that uses both wind power generators and solar heat is an urgent task to improve the utilization rate of natural energy.

The small machine of the present invention has a high-temperature solar heat collector as shown in FIG. 1 and a high-temperature heat storage liquid tank at the bottom. (It is also referred to as a storage tank) It is the best shape that can balance the overall design and safety by requiring piping pipes and installing them separately.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

FIG. 1 is a view of the state of use (also referred to as an external view) showing an embodiment of the present invention, which is a multipurpose heat storage device using a high-temperature solar collector and an electric heater as a whole.

Absorbs and heats.

2 in FIG. 2 is a pressure reducing nozzle that appropriately reduces the pressure because the liquid in the high temperature heat collecting tube expands when heated by sunlight. There is high temperature liquid in the high temperature liquid circulation pipe (upper part) 4. The liquid is sent down by a high-temperature liquid flow circulation pump of 5 to heat the high-temperature liquid in 18 high-temperature heat storage liquid tanks (also referred to as heat storage liquid tanks).

2 in FIG. 2 is a high-temperature heat storage liquid, which has a high heat of 130 to 150 ° C., and can store heat at a temperature more than twice that of the current water heater. There is a working pipe.

In FIG. 2, for example, in the case of heating for a greenhouse, air is sucked from 16 air intakes, and the air passes through 11 air-conditioning / air-blowing pipes, so that the air is heated by 20 high-temperature heat storage liquid. The air blows out from the air blowing port of 13 by the air blowing fan 13 and the heated wind is sent into the greenhouse. At this time, it is necessary to adjust the temperature of the heated air. An appropriate amount of air can be adjusted from the air inlet for temperature adjustment, mixed with high-temperature air by 13 air-blowing fans, and blown as air of optimum temperature.

In FIG. 2, the hot water supply for bathing and cooking is heated through 19 hot water supply heating pipes through 10 water supply adjustment screws from 8 water pipes, but passes through a heat storage tank of 100 degrees or more. For this reason, 19 heating pipes are made of materials that can only be heated up to 95 degrees to prevent water from becoming steam, 9-1 is a water supply adjustment (hot water) screw, and 9-2 is a water supply for temperature adjustment.

In the heat storage tank 18, 20 high-temperature heat storage liquids are stored more than necessary. However, this is because the liquid heated to high temperature by the high-temperature solar heat collector in the upper part 1 circulates from the high-temperature liquid circulation pipe (upper part) 4 to the lower part of the pipe 7, and the high-temperature heat storage of 20 by that heat. Decrease the amount of heat storage liquid by adjusting it to the required amount so that the liquid becomes high temperature and can maintain high temperature for a long time.

The amount of the heat storage liquid 20 can maintain the temperature at which heating and hot water can be used even if the wind power generator and the solar heat collector are not in good weather and do not take effect for 3 to 4 days.

In FIG. 5, 22 below the high-temperature liquid circulation pipe 4 is a heat conduction blade that allows the heat of the pipe to be transferred well to the high-temperature heat storage liquid 20.

FIG. 6 is an enlarged cross-sectional view of the air-conditioning / heating fan pipe 11, and air further passes through the pipe 11 through the pipe 16, while the air in the high-temperature heat storage liquid 20 becomes hot air, Since the hot air advances to the top by the 13 blower fans that rotate, and the hot air cannot be used at a high temperature as it is, low-temperature air is sucked in from the temperature adjustment air intake port at the same time, and the amount is adjusted by 14 The air volume can be adjusted by 23 air volume valves above the air outlet, the air temperature for cooling and heating coming out of 12 air outlets can be determined, and the air volume and temperature can be changed by increasing or decreasing the rotational speed of 13 air fans. It is done.

In order to make the temperature higher than the usual 65 to 75 degrees, heat collecting tube 2 is heated with 25 solar heat reflectors, and if the conditions are met, the heat storage liquid in 24 can obtain a high temperature of 200 degrees. Since it is also circulated through the pipe, it is within an average of 150 degrees and becomes a safe temperature when used.

FIG. 9 shows a controller box 15 in which power is supplied from 6 power lead-ins through 27 switches, 26 to power lines to the circulation pump, 28 a pressure gauge, 29 an automatic timer instrument, 30 Connected with an automatic controller of silicon element, 31 is a high-temperature liquid temperature indicator, safety is checked, 32 is composed of power wiring to the electric heater, and other automatic power meter for commercial power depending on other models, various Various safety check functions are also installed with all automation of temperature, timer, etc.

FIG. 10 is a partial cross-sectional reference diagram of a building rooftop cooling / heating use. From the viewpoint of improving the use of natural energy, the multi-purpose heat storage device using the high-temperature solar heat collector and the electric heater of the present invention is used to generate electric power from the electric heater by wind power generation. An external reference diagram of a series of devices using the machine was displayed.

Referring to FIG. 10 in detail, the overall flow is easy to understand from the left. A-18 is a large high-temperature heat storage liquid tank, B on the right is an ice storage tank, and C is a small wind power generator. Below that there are three D1, but this is a high-temperature solar heat collector, and on the right is a solar power generation module of E, and assuming indoors of the building 37, F1 and F2 cooling and heating indoor fans are displayed. It is the state of use on a series of building rooftops.

From FIG. 10, the liquid in the heat storage liquid tank of A-18 is heated from the four high-temperature liquid circulation pipes (upper part) to the same (lower part) pipes. 5 is sent by a high-temperature liquid flow circulation pump, is circulated and heated, takes air from 16 air intakes, passes through 11 air-conditioning / air-blowing pipes, and switches 36 cooling / warming switching valves to the heating side, F1 And warm air comes out from the indoor fan of F2 and F2, and the room can be heated.

From FIG. 10, when the room is cooled by cooling, the ice-making refrigerant machine 34 in the B ice storage tank generates electricity from the C wind generator and the E solar module via the 33 natural energy lines. The automatic current switch of 38 is activated, and the water in the ice storage tank of B is cooled and frozen, and the amount of use is determined by the size of the ice storage tank. Passing through 35 air-cooling pipes from the air vent and turning the air-cooling valve with 36 air-conditioning switching valves, the system produces cold air from the F1 and F2 air-conditioning indoor fans. Even if the irregularity continues, only the air pipe is passed through the ice storage tank, and the ice does not thaw immediately. Therefore, depending on the size of this tank, it is possible to send cold air for 5 to 6 days.

Fig. 11 is a reference diagram of the exterior appearance of the building rooftop heating and cooling system. In Fig. 10, it is used together with the internal structure diagram. Since the appearance is not refreshing, it is displayed only in the exterior view. There is no sense of incongruity.

The first disadvantage of using natural energy is that the energy obtained due to bad weather is unstable and the required amount cannot be stably used. As shown in Fig. 10, the A-18 high-temperature heat storage liquid tank and B ice storage tank are separated and placed, and their size is stored in the high-temperature liquid. On the other hand, for cooling, ice is stored in the ice storage tank, greatly increasing natural energy. As a method of using it efficiently and accumulating its energy, we have developed a device that greatly improves the disadvantages of using natural energy.

Conventionally, small wind power generators and hybrid generators such as solar power generators have been used for lighting, but full-scale, multipurpose air conditioning equipment that uses both wind power generators and solar heat has been put to practical use. Not.
The product of the present invention makes it possible to store the entire product at a significantly lower cost and for a long time by using highly efficient use of natural energy and accumulating that energy using a method that is not a power storage such as a battery. did.
