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) The present invention relates to a cooling and heating plant using hot water, which is composed of a control unit for controlling a system and a combination thereof.

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.

In other words, the present invention is to provide a heating system using solar hot water developed for the utilization of such solar energy, in particular a large-scale heating and cooling plant structure using the 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. Although it is constructed, the technical development of solar heat collecting part has been carried out more broadly and deeply because the efficiency of the system and the practical application depends on how efficient it is in collecting, storing, and heat exchange.

In particular, the vacuum tube solar heat collecting technology related to the present invention applies the principle of the so-called Thermo Flask to heat and store water by radiant heat of the sun, and this principle is already in Scotland in 1893, more than 110 years ago. It has been used by physicist James Dewar to store hot water for a long time as vacuum insulation of the double skin space minimizes heat losses due to convection and 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, connect the branch pipes on one side of the heat collecting plate at regular intervals to form a circulation circuit, and 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 double vacuum tube has been developed so that a heat pipe equipped with a heat collecting plate is inserted into the glass tube, and the heat pipe is protruded and installed at the top of the glass tube to be sealed with a metal stopper. The inside is vacuumed to block heat loss from the surface of the heat collecting plate to the outside by convection, and there are vacuum tube solar collectors in which two glass tubes are used in the form of a double vacuum tube. If the medium (water) is filled directly into the heat collecting tube and heated, there is a problem of freezing in the cold weather such as winter season and when water suddenly flows into the heat collecting tube heated by solar heat, the heat collecting phenomenon occurs due to thermal stress. In addition, the material of the outer tube and the heat collecting tube is made of glass and is directly connected to the heat storage tank. If any one of the tubes breaks, there is a risk that the 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 maximize the efficiency and economic efficiency of solar heat.The configuration is as shown in Fig. 1 `` Vacuum treatment 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 part is formed inward, and a fixing stopper which is tightly coupled to the upper end of the double glass collector using an O-ring at the lower part of the formed screw part, and a hollow part in which a locking jaw is formed in the center, has a plurality of air holes in the middle of the outer surface. It is formed, the air hole is connected to the vent is equipped with a piston that is moved up and down, the bottom surface is formed with a screw portion is engaged with the screw portion formed in the fixed stopper and the connecting member coupled to the glass collector sealed with an O-ring O-ring is coupled to the outside of the upper end of the cold water flow pipe passing through the center of the connecting member, the cold water flow pipe is supported by the support so that it is located in the center without being in close contact with the bottom surface of the hot water flow pipe is equipped with a corrugated bottom After the upper part of the hot water flow pipe, which is a pipe, It is inserted into the collector and connected to the heat storage tank, the cold water inflow pipe of increasing diameter in the center of the pipe where cold water and hot water can be introduced and discharged is sealed by O-ring to the cold water flow pipe installed in the glass collector. And the O-ring attached to the outer side of the bottom surface of the hot water discharge pipe is inserted to the locking jaw of the hollow portion formed in the center of the connecting member, and then sealed to be combined.

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, and above all, there is a limit in which technology development is made only for the collector.

The present invention has been developed a medium-to-large plant by the forced cold and hot water circulation method, in particular, the solar heat collecting portion of the double vacuum tube type ceramic coated CPC for condensing and reflecting light passing through the bottom of the double vacuum tube to dramatically increase the heat intensity efficiency It is equipped with a compound parabolic concentrator, and the position and size of the CPC reflector are designed in accordance with the engineering and geometric characteristics together with the double vacuum tube to obtain the minimum heat loss and the maximum heat intensity efficiency.

However, since the present invention is intended to provide an entire heating and cooling plant, the heat collecting unit is not necessarily designed or constructed by using only a double vacuum tube type. 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 accumulating part where hot water heated to a predetermined temperature is collected is buried not only on the ground but also on the ground to minimize heat loss and maximize heat preservation, and to utilize the ground space by being buried underground. It is to be secured.

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 unit for control has an integrated control system structure for controlling the collection and storage of heat and 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 sanitary because it is not directly circulated, but even if the vacuum tube is damaged due to an accident or maintenance, water does not flow out due to the inner aluminum plate and the U tube, so it has no characteristic 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.

Referring to the system for controlling the installation configuration of the present invention in horticultural heating in one embodiment as follows.

12 is an automatic control system designed for a configuration in which four types of collectors (here, a single vacuum tube type, a flat plate type, a roof member type, and a double vacuum tube type) are arranged in a test configuration. The heat storage tank 210 is a quarterly heat storage tank, which is named for storing cold water warmed from the heat collecting portion 100 in spring, summer, autumn, etc. and for use in cold winter, according to the object of the present invention. It is buried underground to prevent heat loss, and the tank circumference is covered with a heat insulating material such as fiberglass.

Here, the heat utilization unit 300 includes the space heating of the glass greenhouse 310 and the underground heating of the bed heating and the vinyl house, the integrated operation control system to control them as shown in FIG. Separately configured as a control system to enable independent operation control of each hot water heating system constituting the system.

Here, the individual temperature control system can play the role of 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 each solar system heat collection and heat storage performance, wherein the temperature control system is the outlet temperature of each solar heat collecting module (100A) end and the individual heat storage tank 210 connected to each system It performs the function of starting or stopping the heat medium circulation pump (collecting and heat storage medium circulation pump) installed in the system by using the difference with the temperature of the lower part.

More specifically, as shown in the operation structure diagram of the heat insulation system of FIG. 14, the heat insulation system independently operates only the heat medium circulation pump of the hot water hot water supply system when the temperature difference between the collector outlet temperature and the individual heat storage tank reaches a predetermined value. When the temperature difference between the temperature at the outlet of the solar heat collector (or collector) and the lower end of the heat storage tank drops below the set value according to the start of the circulation pump, the operation of the heat medium circulation pump is stopped.

When the temperature control system plays an independent role, the solar heat collected by each collector is stored in a system heat storage tank connected to each hot water system, so that performance analysis according to the solar system can be performed.

In addition, when the entire system is operated as an integrated system, the temperature control system simultaneously serves to operate each hot water system as an integrated system, so that the temperature at the outlet of the collector and the lower end of the large heat storage tank are respectively. By controlling the temperature difference of the hot water circulating pump, the start or stop of the heating medium circulation pump installed in each hot water supply system.In this way, when each temperature controller is used as a partial control system of the integrated control system, it is different from the independent operation control. Solar heat transferred to the medium is stored in large heat storage tanks.

On the other hand, the space heating control system of the glass greenhouse of the operation control system of the user part starts the two fan coil units installed inside the glass greenhouse to maintain the space temperature required in the glass greenhouse within the required temperature range. And stop control.

The glass greenhouse space heating control system is a fan coil unit that performs the start and stop control of the circulation pump to circulate the high temperature heat storage medium stored in the large heat storage tank. Is a prep pump and the other two are stirred and controlled at regular intervals by a timer installed in series in the space heating control system.

In addition, the bed heating control system performs the start and stop control of two heat storage medium circulation pumps to maintain the bed temperature of the glass greenhouse at a constant set temperature, and these circulation pumps are also installed in the bed heating control system. Like a pump, a timer is controlled to stir at regular intervals.

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

The valve position control of the three-way valve is a glass greenhouse bed 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 glass greenhouse bed heating inlet temperature. In order to supply heating, the bed heating control system adjusts the position of the three-way valve 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. It prevents the supply of heat medium from the high temperature heat storage medium stored in the heat storage tank, and uses only heat storage medium returned from the glass greenhouse to make full use of the solar heat stored in the heat storage medium. .

If the temperature of the heat storage medium returned from the glass greenhouse is lower than the set temperature, the bed heating control system performs the valve position control of the three-way valve to appropriately store the high temperature heat storage medium stored in the large heat storage tank and the low temperature heat storage medium returned. Mix to keep the setpoint. 15 is a structural diagram of a glass greenhouse space heating and bed heating control system.

On the other hand, the ground heating control system, as shown in Figure 16, and performs the control of the two circulation pumps start stop circulating the heat storage medium to XL pipes embedded in the plastic house to maintain the ground temperature of the vinyl house to the required temperature In order to efficiently recycle the heat remaining in the heat storage medium that is returned to the large heat storage tank after the underground heating, like the bed heating control system of the glass greenhouse, the valve position of the 3-way valve installed in the underground heating hot water supply pipe is controlled.

The configuration of the present invention described above is not limited to the horticultural heating as exemplified, hot water is required in large units such as crop drying, aquatic product drying, hot air heating system of high-rise building, large-scale swimming pool or bath, accommodation, etc. It can be used as a hot water system.

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.
