Abstract

PURPOSE:To enable to make a heat accumulating apparatus in a compact structure, by disposing particles of coagulative heat accumulating medium charged hermetically in moisture-impermeable packing material with proper spacing in a tank-shaped container of a heat accumulating apparatus used for hothouse culture. CONSTITUTION:In a tank-shaped container 3 of a heat accumulating apparatus, particles 4 of coagulative heat accumulating medium consisting of Na2SO4. 10H2O or the like having a melting point of about 10-30 deg.C, charged hermetically in a moisture-impermeable packing material such as polyethylene or the like, are disposed with proper spacing from each other. In case of collecting superfluous heat in a hothouse in the daytime, a control section 7 drives a fan 5 for performing heat collecting operation when the temperature in the hothouse detected by a detector 6 becomes higher than a prescribed temperature. On the other hand, when the temperature in the hothouse becomes lower than a prescribed temperature at night, heat releasing operation is performed by driving the fan 5. Thus, it is enabled to obtain a compact, energy-saving heat accumulating apparatus used for hothouse gardening, which has a high efficiency of heat exchange.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat storage device using coagulable heat storage 43. %
This article relates to a heat storage device that effectively saves energy in heating and cooling greenhouses for greenhouse horticulture.

Generally, greenhouse cultivation of crops in winter is suppressed by high temperature ventilation during the day, while heating is required at night to ensure the growth TrAK of the cultivated crops.

Although heating machines that use petroleum as fuel are widely used, as the price of petroleum has soared, energy-saving heating methods using alternative energy have been developed and some of them have been put into practical use. One of these energy-saving heating methods is a method that makes full use of solar heat. This uses the greenhouse as a heat collector to store the excess heat that was thrown into the atmosphere through ventilation out of the solar heat that reaches the greenhouse during the day.
This method uses 'A1' as a heating heat source at night, and is known as the underground heat exchange method and the ice storage heat exchange method.
In the first method, the surplus amount is stored underground through a heat exchanger vibrator buried underground in the greenhouse, and in the latter method, it is stored as hot water in a water tank using a heat exchanger.

However, in the underground heat exchange method, the area of the pipe heat exchange section is the same as or larger than the area of the greenhouse, and the number of buried pipes is 84, which means that all of the vibrators are buried underground in the greenhouse, so materials such as the vibrator and construction costs are required. A huge amount. However, there are problems such as high humidity in the greenhouse, which increases the incidence of diseases in cultivated crops.

On the other hand, the ice storage heat exchange method has a problem in that, since the specific heat of water is small, a large water tank must be placed inside or outside the greenhouse in order to store a large amount of heat.

As a result of various studies on the key points of such conventional heat storage methods, the inventors of the present invention have solved these problems by using a coagulable heat storage material and providing a method and mechanism for arranging it to improve heat exchange. The point is that it can be easily solved.I know that the present invention has been completely completed.That is, the present invention is based on the introduction of air 11.
A smoky container is arranged such that an appropriate space is maintained inside the smoky container f]-, ! -4
It is sealed and filled with a packaging material that does not have TSr'lt' properties, and outside air is introduced into the inner layer 1 of the smoke container, and heat is exchanged through the heat storage material arrangement part to emit 211. ii: Blower with Q 'g, temperature j4. Measures and displays outside air temperature. 10 sending kite B in relation to the detector and the detected temperature? It consists of a control section that increases +11', and is a heat radiation ↑ga.

Hereinafter, all the embodiments of the present invention will be described. i'i
I will explain using the V button. FIG. 1 is a schematic diagram showing the configuration of the heat storage device according to the present invention, where / is an air inlet, -2 is an air outlet, 3 is a smoke-shaped container, and G is a non-moisture permeable packaging material. The hermetically packed coagulable heat storage material, J is a blower, the name is a temperature detector, and 7 is an 11 control unit, respectively. This heat storage device 17 is equipped with an external FP air inlet []/output [], 2, and a smoke-like container 3, and the inside of this smoke-like container 3 is sealed and redundant by a moisture-permeable packaging material. The Q-temperature storage energy drips! ”! It is arranged so that a space of 1 is held, and 7, in this case, 24 volumes of air [ko/deceased; 1%
This can be appropriately selected without any particular restrictions. The smoky container 31 may have a box shape as shown in Figure 1, or may have a cylindrical shape (L) with a circular center (C) air inlet (or outlet), and an air outlet inside the periphery. (or an introduction can also be provided.) The coagulable heat storage material that is inside the ?-shaped container and the ? 19.In order to completely prevent leakage and at the same time to prevent deterioration during long-term use, a certain amount of the product is stored in a container sealed with a non-moisture-permeable synthetic resin or metal packaging material.1.
The hermetically sealed package of the coagulable heat storage material q is inside the smoke container 3 (
A bag-like, plate-like, or tubular shape is suitable for the arrangement. Such packaging materials include polyethylene, ethylene-vinyl acetate copolymer, polyvinyl chloride,
Nylon, iron, and stainless steel hats are suitable. Sealed packages in which the coagulable heat storage material is in the original plate phase come into contact with the forced air and perform heat exchange, so the surface of the package is exposed to 1 g of air and the product is thickened. , but the I is too big
F. It is necessary to use an arrangement method that does not cause loss of force IF. Examples of such arrangement methods include, for example, bag-shaped sealed packages, plate-shaped sealed packages, bar-shaped sealed packages filled with a coagulable heat storage material in a tiered manner, and smoke-shaped containers. Corresponding to the cross-sectional shape of 3, concentric polygons ((a method of arranging circular or spiral-shaped items on shelves, a method of arranging long tubular sealed packages in a spiral shape, etc.) One method is to arrange the hole space like a 4V stone.Second
An example of this is shown in Figure 3.

The coagulable heat storage material that can be used in the present invention is the surplus heat that is discarded into the atmosphere through ventilation out of the solar heat that reaches the greenhouse during the winter. Because heat is stored in the heat storage material, if the melting temperature of the heat storage material is higher than the temperature inside the greenhouse during the day, heat cannot be stored, and if the melting temperature is too low, heat cannot be radiated sufficiently at night even if the room temperature drops. Since the growing temperature of the cultivated crops (1:y) cannot be secured, a range from melting p101;!rL 10 r2 to JOC is appropriate.3, Maa ζK, 44B, 4B, i

There are also those mixed with r2-gH20, etc. These are usually used in combination with anti-refrigerating agents and thickeners.

A blower S is attached to force all the external air (mainly temperature guiding air) into the annular container 3 from the inlet/inlet along the arrow 1 - The sealed package of coagulable heat storage material is placed. First thing. The air is discharged to the outside air again from the space K [-Multi-way derived 1 co β. At this time, there are no particular restrictions on the installation location of the blower S. It is fine as long as it has. Therefore, it is also possible to blow air into the air inlet. (A temperature detector 6 detects the outside air temperature (mainly the temperature inside the greenhouse) and a control unit 7 that starts and stops the blower S from the detected temperature and the set temperature.

Therefore the temperature sensor B and? There is no peace of mind to place the shameful part 7 of the white container 8 on the (+ili but part) of the white container 8, and it is bJ's function to move it in the wind and make it function. .

For example, when using the heat storage device of the present invention to collect surplus heat of -1, 1/1, the total temperature inside the greenhouse (
B) detects the heat collection set temperature or higher (e.g., 2 s-C).
), move the blower (5) to operate the heat collection.
If the temperature drops below that, the blower will stop. In addition, when heat is being dissipated at night, when Vr is below the heating set temperature (for example, 10R) and the temperature in the greenhouse drops, the blower (,5) will start operating and dissipate heat, and when the temperature exceeds that temperature, the blower will stop. The control section (7) is in control of the rod ``7,000''.

As described above, the heat storage device of the present invention has a considerably larger amount of heat storage than water.Since it uses homogeneous heat storage materials, it is possible to use a large water tank (heat storage) like a water heat storage heat exchange type. It is possible to reduce the R1 of the heat storage device without needing it, and it is possible to reduce the R1 of the heat storage device.
