[0001] SOLAR HEAT ACCUMULATOR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat storage system using solar heat, and more particularly, to providing a heat storage system that can be utilized for heating or drying in a state of collecting and storing solar heat or directly.

In general, as a means for generating heat for heating or drying, fossil fuels such as oil, briquettes and coal are burned to obtain heat energy, or electric energy is used to convert heat energy.

As described above, systems for heating or drying using fossil fuels have been developed and used variously. A typical example will be described with reference to FIG.

The heating or drying system 1 is provided with a heat generator 3 having a fossil fuel or electricity as an energy source in a heating or drying place 2 such as a greenhouse, Hot air or hot water.

Hot air or hot water generated from the heat generator 3 is supplied to the room of the heating or drying room 2 directly or by supplying the hot water circulation unit 5 to the floor of the heating or drying room 2 And the hot water is circulated to perform heating or drying.

The use of such fossil fuels requires additional devices for burning fossil fuels, as well as the need for periodic replacement due to short life span of these devices due to combustion Lt; / RTI >

In addition, the cost of fossil fuels that are depleted day by day rises rapidly, causing a lot of cost burden to users, causing exhaustion of fossil fuels along with environmental pollution, accelerating global warming and destruction of the ozone layer by increasing carbon emissions, Climate change also poses a problem that causes more damage to users.

In order to solve this problem, methods and apparatuses have been developed and used so that they can be utilized for heating or drying by using clean energy and infinite solar heat in recent years.

Conventionally, heating using solar heat is a hot water circulation system which obtains hot water by using solar heat and supplies it to home heating, and is mainly used for heating small-sized houses. This system is used for heating of a drying area or gardening facility , It takes a lot of time for initial heating and the thermal efficiency is low.

There is a utility model registration No. 20-0316737 (solar heating system) as a device that can generate hot air using solar heat and can store hot water using hot wind, but it has a constant heat storage and circulation system to keep the heating temperature constant It is not realistic because there is not.

That is, there is a problem in that the sunlight is not available all year round and the sunlight can not be used at the time of rainfall snowfall or overcast cloudy days, and in particular, at night, there is no sunlight.

In addition, Patent Document 10-0449831 (building veranda structure provided with a solar absorbing and converting device) as a literature information of the prior art has a heat storage portion in the form of a pipe having a heat storage function in a solar heat collecting box, but a small amount of heat medium stagnated in the pipe There is a problem in that it can not be used for heating in a large scale because it is difficult to heat the room for a long period of time at a time when there is no solar heat due to the limited nature and is limited to a veranda in an apartment space.

In addition, there are other devices that use solar heat to perform heating or drying, but they can not perform heating and drying using purely solar heat, and equip the facilities using fossil fuel or electric energy as an auxiliary means Most of the forms.

In this case, formally, fossil fuel or electric energy is used as a supplementary means, but in reality, fossil fuel or electric energy is the main factor, and the use of solar heat is often converted into a supplementary form. In severe cases, There is no system for heating or drying by using actual solar heat or by storing solar heat, since the means used are often intended to be visually visible.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a solar collecting chamber for collecting solar heat required for heat storage, a regenerating chamber for storing and reusing the collected solar heat, And as an auxiliary means to maintain the temperature of the target bar in rainfall and overcast weather, it is dried using solar heat, and only a part of the day without sunlight uses the general power supply, so it is environmentally friendly In addition, when the drying is not carried out, the drying room can be used for other purposes, thereby achieving the object of increasing the usability.

The present invention provides a solar heating system capable of substantially heating or drying a solar heat, and capable of assisting solar heat by using electric energy only on a day without sunlight, thereby maximizing efficiency, Or drying to prevent environmental pollution and reduce dependence on imported energy, thereby increasing national competitiveness.

In addition, it is possible to reduce the economic burden of the users, to increase the heating or drying area because of high efficiency, and to have a variety of effects such as excellent drying and excellent manpower saving when the drying area is wide .

However, the drying chamber 150 is located on the ground, It is most preferable that the heat storage chamber 130 is disposed in the lower part of the drying chamber 150 so as to be exposed to the sun at all times.

The solar collecting chamber 110 is constructed such that the frame 111 formed on the roof of the drying chamber 150 is closed with a heat insulating wall 112 and painted in black so as to help absorb sunlight, The south and the ceiling are provided with a collection wall 113 made of a transparent material and a collection ceiling 114 so that the sunlight can be easily transmitted.

The collection wall 113 may be made of various materials such as glass and acrylic. However, it is preferable to use a glass (a sunlight) made of poly (ethylene terephthalate), because the economic burden can be reduced and the collection efficiency can be increased.

The collecting wall 113 and the collecting ceiling 114 are provided with airtight means for preventing the solar heat collected by using the airtight material such as the roof of the heat insulating wall 112 and the drying chamber 150, Wanted would be natural.

The collecting wall 113 is formed of two pieces of an outer wall 115 and an inner wall 116. The inner wall 116 has a predetermined distance from the outer wall 115 while an inlet 117 is formed below the inner wall 116, The cold air inside the solar collecting chamber 101 flows into the inlet 117 and flows into the solar collecting chamber 110 by the convection phenomenon circulating to the outlet 118. [ Allow the air to heat up.

The solar collecting chamber 110 is provided with a supply tube 119 for supplying the collected solar heat to the heat storage chamber 130 and a heat storage chamber 130 is provided at a position opposite to the supply tube 119 And a discharge pipe 120 for circulating the air cooled by the heat exchange to the solar collecting chamber 110 for heating.

The inlet 121 of the supply pipe 119 is positioned above the solar collecting chamber 110 where the heated air is located and the outlet 122 of the discharge pipe 120 is connected to the bottom surface of the solar collecting chamber 110 And the circulation fan 123 is installed in the outlet 121 so that the air in the solar collecting chamber 110 can circulate through the heat storage chamber 130.

When the indoor temperature of the solar collecting chamber 110 is higher than the predetermined temperature, an opening / closing door 125 is further provided between the solar collecting chamber 110 and the drying chamber 150 to directly supply hot air to the drying chamber 150 It is natural that the inlet 120 of the supply pipe 119 is provided with the opening and closing door so that the cold air is supplied to the heat storage chamber 130 to prevent the heat from the heat storage chamber 130 from being lost .

The operation of the circulating fan and the opening / closing door may be performed by comparing the information of the temperature sensor installed in the solar collecting chamber 110 with a value set by a controller to which the temperature sensor is applied.

The heat storage chamber 130 is provided with a heat insulating means 131 on the bottom surface and four sides except for the top surface and a bottom surface made of iron cone such that it can withstand the loads of the drying chamber 150 and the solar collecting chamber 110 132).

A heat storage layer 133 which receives hot air from the heat collection chamber 110 and stores heat by heat exchange; a heat storage layer 133 which is formed above the heat storage layer 133, And a heating layer 134 which receives the water and performs heating while constituting the bottom of the drying chamber 103.

The heat storage layer 133 is disposed in a staggered manner and in multiple stages in the form of a corrugated tube so as to increase the heat exchange property on the base 132. The heat storage tube 135 is disposed in a multi- The heat storage material 135 is connected to the discharge tube 119 and the discharge tube 120. Hot air is supplied to the outer side of the heat storage tube 135 to fill the heat storage material 136 so that heat can be stored by heat exchange.

It is preferable to use a gravel-like material for the heat storage material 136 so as to sustain the heat storage time. A heating pipe 137 is arranged in the heating layer 134 so as to circulate hot water, And then a finish layer 138 is formed by applying a paste.

The drying chamber 150 is provided with a vertical partition 151 extending from the bottom surface to the ceiling so as to have a predetermined space at a position of the opening and closing door 125 connected to the solar collecting chamber 110, (152) and a drying room (153) for performing substantial heating or drying.

A plurality of supply fans 154 may be installed in the vertical partition 151 for partitioning the supply room 152 and the drying room 153 to supply hot air and a horizontal partition wall And a circulation passage 156 through which the air passed through the drying chamber 153 can circulate through the supply chamber 152 and the drying chamber 153 is formed.

The drying chamber 153 is provided with a dehumidifier 157 for dehumidifying the moisture generated in the drying process and discharging the moisture to the outside, and a door 158 is installed in the vertical partition 151 and the drying chamber 153, It is natural that the cold air in the drying room 153 can be discharged to the outside while the dehumidifier 157 and the door 158 are also controlled by the controller having the information about the operation.

The auxiliary means 170 is connected to the roof of the solar collecting room 110 or a hot water supply device for supplying hot water generated by the solar power generating module 171 installed on the side or the front of the heat storage system 100 172 supply hot water to the heating layer 134 of the heat storage chamber 130 and provide a heater 175 in the supply room 152 of the drying chamber 150 to assist the drying temperature.

The hot water supply unit 172 and the heater 175 may be configured to operate in response to a normal power supply to generate hot air required for drying when there is no sun, such as in a cloudy weather, rainfall, or snowfall.

A process of performing drying using the solar thermal storage system 100 to which the above-described technique of the present invention is applied will be described as follows.

When there is a sun, solar heat is collected through the solar collecting chamber 110. Heat is generated in the collecting process, and the internal air circulates from the lower side to the upper side by a natural convection phenomenon, As a result of the experiment, it was confirmed that the internal temperature of the solar collecting room (110) reached 75 ℃ in the summer, and the solar heat reached 50 ℃ even during the relatively weak winter season.

The reason why the temperature of the air in the solar collecting chamber 110 can be raised by the natural convection due to the solar heat is that the collecting wall 113 made of a transparent material has the outer wall 115 and the inner wall 116, When the air located in the space between the outer wall 115 and the inner wall 116 is heated by the solar heat, the air is raised upward and discharged to the outlet 112. Cool air flows through the inlet 121 located on the lower side And is circulated in the form of natural convection heated and discharged to quickly heat the air inside the solar collecting chamber 110 to make it hot.

In this process, since the inside of the heat insulating wall 112 located in the north is painted in black, it is natural that it is possible to enhance the room temperature by increasing the heat absorbing property.

When the temperature of the air reaches the target temperature by the setting of the temperature sensor and the controller, the air is supplied to the heat storage chamber 130 through the supply pipe 119 and is heat-exchanged to be stored in a low temperature state And then supplied to the tropical air collecting chamber 110 through the discharge pipe 120 to be circulated heated by the solar heat.

It takes too much time to circulate the hot air of the solar collecting chamber 110 through the heat accumulating chamber 130 and return to the solar collecting chamber 110 in a natural state, The circulation fan 123 is installed in the outlet 122 of the heat exchanger 120 to be forcedly circulated so that efficient storage can be performed.

When the indoor temperature of the solar collecting chamber 110 is high, the hot air is supplied to the heat storage chamber 130 and the opening / closing door 125 connected to the drying chamber 150 is opened, It will be appreciated that it is also possible to supply hot air to the drying room 130 to help dry the laundry together with the drying heat supplied through the heat storage room 130.

The heat storage tube 135 of the heat storage layer 133 constituting the heat storage chamber 130 is heat exchanged while passing through the jig jig and multistage in the heat storage chamber 130 receiving hot air from the heat collecting chamber 110 Heat is conducted to the heat storage material 136 filled in the outside of the heat storage tube 135 so that the heat storage material 136 can store heat.

Of course, since the bottom and four sides of the heat storage chamber 130 block heat leakage to the outside by the heat insulating means 131, the heat storage is excellent, and the heat thus accumulated is discharged to the bottom of the drying chamber 150 To the drying chamber 150 to perform drying.

A heating side 134 is formed above the heat storage layer 133 so that hot water heated by the hot water supply device 172 is supplied to the heating pipe 137 by the solar power generation module 171 constituting the auxiliary means 170. [ So that the drying efficiency can be doubled because the heat required for drying is circulated and supplied to the drying chamber 150.

The hot air supplied to the drying chamber 150 is forcibly circulated through the supply chamber 152 and the drying chamber 153 by the plurality of supply fans 154 installed in the vertical partition 151, And the air in the drying room 153 is supplied to the drying chamber 153 through the circulation passage 156 formed above the drying chamber 150 by the horizontal partition wall 155 do.

Of course, it is natural that the moisture generated during the drying process of the dried material in the drying chamber 153 is dehumidified through the dehumidifier 157, and the moisture dehumidified is discharged to the outside of the drying chamber 150.

When the temperature of the solar collecting chamber 110 is low, the opening / closing door 125 is closed to dry only with heat generated from the heat storage chamber 130. If the temperature is insufficient, And the auxiliary heat is supplied from the heater 175, which receives power from the photovoltaic module 171 and operates.

When the weather is cloudy or there is no sunlight due to rainfall, the heater 175 installed in the supply room 152 receives the normal power and generates heat. The heat is supplied to the supply room 152 To the drying chamber 153 to enable drying regardless of the weather conditions.

Of course, although not shown in the drawings of the present invention, natural drying may be carried out using sunlight and heat by providing a shelf for drying inside the solar collecting chamber 110, and it is easy to carry the object to be dried A rail and a carrier may be installed on the floor.

In the case of the present invention, since almost all of the sunlight is used and only a part of the sunlight-free sunlight is used, the solar energy is highly efficient and environment-friendly because it does not use artificial resources.

In addition, when the drying is not performed as in the winter season, since the temperature of the drying chamber rises naturally, the drying chamber can perform other operations using the drying chamber.
