BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating plant using solar heat. In particular, a fixed-condensing-collecting unit in the form of a double vacuum tube with a reflector, a quarterly heat storage unit buried underground to prevent heat loss, and a FU as a standardized distribution system (Field Unit) relates to a heating plant using hot water consisting of a module and a control unit for controlling a system coupled thereto.

Concerns about the exhaustion of fossil fuels and environmental pollution have led to the development of alternative energy sources, and the development of technology using solar heat or securing future energy sources using hydrogen, wind power or tidal power is being actively promoted. In order to proactively cope with international environmental treaties such as the Uruguay Round and the WTO, the development and use of environmentally friendly energy sources, and technologies that utilize solar energy have been developed and researched at the national level.

In particular, solar heat is a source of energy to be infinitely supplied with the birth of the earth, the present invention also converts cold water into hot water using solar heat and then stores it in a storage tank tank so that it can be used when needed, so that no fuel costs are used to heat water. Not only that, there is no concern about environmental pollution, and above all, the technology to utilize solar energy that can bring about individual national energy saving effect in the era of high oil prices.

The present invention is a heating system using solar hot water developed for the utilization of such solar energy, in particular to provide a large heating plant structure using solar heat as an energy source.

In general, the hot water system that converts cold water into hot water by using solar heat is introduced into the pipe, and when the cold water inside the pipe is heated by heating the pipe with solar heat, the hot water is stored in a heat storage tank and used as a basic principle. It is constructed, but the technical development of the solar heat collecting part has been carried out more broadly and deeply because the efficiency of the system or the practical application depends on the efficiency of the heat collection, heat storage and heat exchange.

In particular, the vacuum tube solar heat collection technology related to the present invention is applied to the principle of the so-called Thermo Flask, which heats and stores water by the radiant heat of the sun, and this principle is the physics of Scotland in 1893, more than 110 years ago. It has been used by James Dewar for a long time to store hot water as it vacuum-insulates the double skin space to minimize heat loss due to convection or heat conduction.

Here, the solar collector (or the collector) is divided into a flat panel and a vacuum tube solar collector in consideration of its external structure and applicability, and the structure of the flat solar collector is made of copper or aluminum as shown in FIG. Form a heat collecting plate with a special chemical treatment on the surface of the thin metal plate to absorb the sunlight as much as possible, and connect the branch pipes to one side of the heat collecting plate at regular intervals to form a circulation circuit, and then cover the solar heat with a transparent cover. will be.

However, the flat plate collector may be used by directly heating water in the collector, but in an area where the cold weather exists in winter, the antifreeze is used as a heat medium rather than water, and the antifreeze that is heated while passing through the collector adopts a method of heating the water secondaryly. In addition, since the solar heat required for a relatively low temperature of less than 80 ° C uses a lot of heat loss from the heat collecting plate to the outside due to convection phenomenon, there is a problem such as the heat collection efficiency drops to about 50% or less.

In order to compensate for this, a method of using a glass tube in the form of a (single) vacuum tube has been developed, and a metal stopper is inserted in which a heat pipe equipped with a heat collecting plate is inserted into the glass tube and a heat pipe is projected to the top of the glass tube. And heats the inside of the heat collecting plate to prevent heat loss from the outside by convection. There are also vacuum tube solar collectors in which two glass tubes are used in the form of a double vacuum tube. . However, in this case, the method of heating the medium (water) by filling it directly into the heat collecting tube is a problem of freezing in cold weather such as winter season, or when the water suddenly flows into the heat collecting tube heated by solar heat, thermal shock occurs due to thermal stress. There is a problem that the collecting tube is broken, and if the tube is broken, there is a risk that water in the heat storage tank leaks into the broken tube.

In order to solve the problems of the conventional vacuum tube solar collector, the present inventors have developed a double vacuum tube solar collector module (Patent No. 0449958) equipped with a coaxial heat sinking channel (patent No. 0449958). It is heated directly with heating to minimize heat resistance, and also to prevent heat shock because physically separated from the heat medium antifreeze and ultimately the fluid (water, etc.) to be heated using solar energy. A pipe having a specially designed coaxial thermosyphon flow path is charged inside the double-tube glass tube vacuum-treated between the tube and the tube, and the space between the charged pipe and the collecting tube is filled with antifreeze, and the heat is collected. At the top of the tube absorbs thermal expansion to absorb excessive thermal expansion of the antifreeze To prevent freezing in winter and to maximize the efficiency and economic efficiency of solar heat.The construction is as shown in Fig. 17. The vacuum treatment is performed between the outer tube and the collecting tube where the black coating is painted on the outer tube side. In a solar collector using the double pipes; A screw portion 8 is formed inward, and a fixing stopper 6 closely coupled to an upper end portion of the double glass collector 2 using an O-ring 7 in the lower portion of the formed screw portion 8, and a locking jaw (in the center). A hollow portion 22 made of 21 is formed, and a plurality of air holes 11 are formed in the middle of the outer surface, and the air holes 11 are provided with a vent 12 equipped with a piston 12 which is moved up and down. And a connecting member 9 which is coupled to the bottom surface of the glass collector 2 by being sealed with an O-ring 14 while being formed with a screw portion 10 engaged with the screw 8 formed on the fixing stopper 6 at the bottom thereof. And an o-ring 17 coupled to the outside of the upper end of the cold water flow pipe 3 passing through the center of the connecting member 9 and positioned at the center without being in close contact with the bottom surface of the hot water flow pipe 4. 15 is equipped with a cold water flow pipe (3) supported by the outer pie with a pleat (24) at the bottom After the upper part of the phosphorus hot water flow pipe 4 is seated and inserted into the glass collector 2 into which the antifreeze 5 is injected, the pipe 16 is connected to the heat storage tank 1 so that cold water and hot water can be introduced and discharged. The cold water inflow pipe 25 having a larger diameter in the center thereof is coupled to the cold water flow pipe 3 mounted on the glass collector 2 while being sealed with an O-ring, and attached to the outside of the bottom surface of the hot water discharge pipe 16. The O-ring 23 is inserted into the hooking jaw 21 of the hollow portion formed in the center of the connecting member 9, and then sealed to be completed.

However, the above patented collector technology can be used in home or small scale hot water heating system, but there are limitations in capacity of medium and large scale hot water heating system such as flower complex and welfare facilities that require large scale heating. If multiple units are installed in accordance with the capacity, there is a disadvantage in that a lot of costs are required for management and control.

The present invention has been developed a medium-to-large plant by the forced cold and hot water circulation system, in particular, the solar heat collecting portion of the double vacuum tube type by reflecting the sunlight passing through the pipes and tubes of the various double vacuum tubes to increase the heat-intensive efficiency dramatically It is equipped with ceramic coated CPC reflector (Compound Parabolic Concentrator), and the position and size of CPC reflector is designed to meet the engineering and geometric characteristics together with the double vacuum tube to achieve the minimum heat loss and maximum heat intensity efficiency. will be.

However, since the present invention is intended to provide an entire heating plant, the heat collecting unit is not necessarily designed or constructed by using only a double vacuum tube type, and the applicant of the present invention mentioned above registers a patented "coaxial heat siphon flow path." A double vacuum tube type solar heat collecting module (Patent No. 0449958), as well as elasticity that can be used by mixing a flat plate collector, a single vacuum tube type, a roofing type and the like according to the installation requirements.

In addition, the heat accumulator, where hot water heated to a predetermined temperature is sent and collected, is buried not only on the ground but also on the ground to minimize heat loss and maximize heat preservation, as well as to secure the benefit of utilization of the ground space by being buried underground. It was made possible.

In addition, the heat utilization portion is designed to increase the solar heat sharing rate by efficiently using the stored hot water, and maximizes the efficiency by using a so-called electronic control system, the heat utilization portion that exists in a variety of applications depending on the use, thus the plant of the present invention The automatic control system for controlling has an integrated control system structure for controlling the collection and storage of heat storage and the storage of thermal storage water.

The independent heating plant of the present invention equipped with a heat collecting unit, a heat accumulating unit, a using unit and a control unit is manufactured by standardizing the heat collecting module, that is, the unit unit module (Field Unit Module) of the heat collecting unit by four types of FU modules based on the total surface area. This helps to overcome the confusion and inconsistency of different plant installation site conditions that are frequently seen from the design of all large-capacity plants to the construction and post-maintenance, and the standard design and standard construction for each FU module are made to save installation costs and reduce air. It is introducing a concept of standardization which is easy and efficient after maintenance.

Therefore, there is no calcification and corrosion phenomenon of the solar heat collecting module, and it is possible to secure and maintain hot water at a desired temperature by the electronic control and independent secondary piping structure by the so-called automatic operation, and the cold water inside the heat storage tank is transferred to the U pipe inside the vacuum tube. Not only is it hygienic because it does not circulate directly, but even if the vacuum tube is damaged due to an accident or maintenance, water does not leak out due to the inner aluminum heat-transfer plate and the U-pipe, so that there is no risk of contamination and leakage.

In addition, since the energy obtained from the heat exchanger can be applied to various uses, it is possible to make the best use of the characteristics of the large-capacity central heating plant.

FIG. 11 is a view illustrating the FU24 model of FIG. 6A, in which two units of vacuum tubes 110 and FU modules 500 are arranged in units of four per block, and connected to the heat storage tank 210.

The configuration of the so-called automatic control system 400 for electronically controlling the above-described configuration is different depending on the FU module 500 according to various models or installation conditions consisting of the FU module 500, but the basic configuration is the same. Referring to 12 to describe a system for controlling the installation configuration of the present invention in horticultural heating in one embodiment as follows.

12, four types of collectors (here, single vacuum tube type 130, plate type 140, roof type 150, and double vacuum tube type 160) are fitted to a configuration in which test collectors are arranged. The automatic control system is designed, and the heat storage tank 210 of the heat storage unit 200 is a quarterly heat storage tank, and stores hot water warmed from the heat collecting unit 100 in spring, summer, and autumn, and then uses it in cold winter. In the name given in order to, if the purpose of the present invention is buried underground to prevent heat loss, the tank circumference is covered with a heat dissipating material such as glass fiber.

Here, the individual temperature control system 450 may serve as an independent control system for the operation control of the four types of hot water system constituting the entire system.

In this case, it can be used in the experiment to analyze the solar heat collection and heat storage performance of each solar system, wherein the temperature control system 450 is the outlet temperature of each solar heat collecting module (100A) end and the individual heat storage tank connected to each system ( By using the difference between the temperature of the lower end of the 210 and the heat medium circulation pump (collecting and heat storage medium circulation pump) 470 installed in the system performs a function to start or stop.

More specifically, as shown in the operation structure diagram of the temperature control system of FIG. 14, the temperature difference system independently of the hot water supply system when the temperature difference between the outlet temperature of the heat collecting unit 100 and the individual heat storage unit 200 reaches a predetermined value or more. When only the heat medium circulation pump 470 is operated and the temperature difference between the temperature at the outlet of the solar heat collecting part 100 and the temperature of the bottom end of the heat storage part 200 decreases below the set value according to the start of the heat medium circulation pump 470, the heat medium circulation pump 470.

In addition, the bed heating control system 414 performs the start and stop control of the two heat storage medium circulation pumps 484 to maintain the bed temperature of the glass greenhouse at a constant set temperature, and these circulation pumps 484 also Like a circulation pump 482 installed in the space heating control system 412, it is controlled to be stirred by a period of time by a timer.

This control system is a valve of a three way valve 486 installed in the bed heating hot water supply pipe 490 for efficient recycling of the heat remaining in the heat storage medium returned to the large heat storage tank after bed heating in the glass greenhouse. Perform position control.

The valve position control of the three way valve 486 is performed by mixing the high temperature heat storage medium supplied from the large heat storage tank and the low temperature heat storage medium returned from the glass greenhouse according to the set temperature of the glass greenhouse bed heating inlet at an appropriate ratio. In order to supply the glass greenhouse bed heating, the bed heating control system 414 is a three-way valve (486) when the temperature of the low temperature heat storage medium returned from the glass greenhouse is still higher than the temperature required for bed heating of the glass greenhouse. ) By controlling the position of the heat storage tank 210 to prevent the supply of the heat medium coming from the large heat storage tank 210 so as not to use the high temperature heat storage medium stored in the heat storage tank 210, but only by using the heat storage medium returned from the glass greenhouse It plays a role to make full use of solar heat stored in media.

If the temperature of the heat storage medium returned from the glass greenhouse is lower than the set temperature, the bed heating control system 414 performs the valve position control of the three-way valve 486 to store the high temperature heat storage medium stored in the large heat storage tank 210. And a suitable amount of the low temperature heat storage medium is returned to maintain the set value. Fig. 15 is a structural diagram of the glass greenhouse space heating and bed heating control systems 412 and 414.

Moreover, since the heating heat can be used as an energy source and can be utilized as a cooling system by an endothermic or adsorption freezer, its practicality is not limited to the heating system, and the heat can be used as a heat source to produce higher temperature heat of higher temperature. The range of utilization of the tank should not be limited only to the hot water temperature range of the tank, and it can be used for both cooling and heating as well as selective use of cooling.

Therefore, it is possible to heat cold water with hot water by heating solar energy without limitless pollution as an energy source, and this heated hot water can be cooled and heated as a heat source, making it an air-conditioning system absolutely necessary in the high oil price era, and there is concern about exhaustion of fossil fuel or environmental pollution. There is no effect of improving the living environment as well as greatly contribute to the development of national industry.
