されている。DETAILED DESCRIPTION OF THE INVENTION In conventional greenhouses that utilize solar heat, as a means of heating at night, the optimum temperature for crops held by the air in the greenhouse during the day (10°C to 40°C) is used.
A device is used that uses a heat storage material to absorb and store excess heat that exceeds the temperature (around 100°F (approximately 30°F)), and then releases this stored heat at night to heat the inside of the greenhouse.

A heat storage material that uses a substance with a melting point between °C and 40 °C and that transfers a large amount of heat due to phase change is used. A heat storage type that effectively absorbs and stores the latent heat of water vapor present in the air, and is configured to release this stored heat at night to maintain the temperature inside the greenhouse at the appropriate temperature for crops for a long time at night. The purpose is to provide greenhouse heating equipment.

を付設したものである。Each heat storage material-filled double tube 7 is constructed by placing a metal outer tube 10 over the outer periphery of a metal inner tube 9 equipped with seven flange 8, 8 at both ends. A sealed chamber 12 is formed by closing the space between the inner tube 9 and the outer tube 10, and a heat storage material 13 is sealed in the sealed chamber 12 to form an integral unit.

上記の如き構成から成る蓄熱式温室暖房装置の作用を述
べる。The operation of the regenerative greenhouse heating system constructed as described above will now be described.
温室２内の空気は送風機５によって常時各蓄熱器４，４

通過する空気より多孔部材１４及び内管９を介して蓄熱
材１３に伝導され、その余剰熱は融解熱として蓄熱材１
３により効率良く吸収されて蓄えられる。Air inside the greenhouse 2 is constantly supplied to each heat storage device 4 by a blower 5.
．． It is circulated within greenhouse 2 during the day.
absorbs enough solar heat and the temperature inside the greenhouse 2 rises above the optimum temperature for crops (108C to 408C) and exceeds the melting point of the heat storage material 13 and generates surplus heat, the surplus heat passes through the heat storage device 4. The air is conducted to the heat storage material 13 via the porous member 14 and the inner tube 9, and the excess heat is transferred to the heat storage material 13 as heat of fusion.
3, it is efficiently absorbed and stored.
また蓄熱材は熱を十分に吸収し得る能力を持っているの
で多孔部材１４は常に温室内の気温より低温に維持され

、そのとき気化潜熱を放出し、その気化潜熱も又多孔部
材と内管を介して蓄熱材により効率良く吸収されて蓄え
られるのである。In addition, since the heat storage material has the ability to sufficiently absorb heat, the porous member 14 is always maintained at a lower temperature than the temperature inside the greenhouse, and when air passes through the heat storage device 4, no heat is generated in the air. The water vapor is cooled and condensed by the porous member 14, releasing latent heat of vaporization, which is also efficiently absorbed and stored by the heat storage material via the porous member and the inner tube.
そして夜間において外気温の低下に伴なって温室２内の
気温が作物の適温（１０℃〜４０℃）以下になって蓄熱
材１３の融点より下ると、蓄熱材１３は凝結して、それ

４内を通過する空気に効率良く伝導されて温室２内の気
温が高められ、作物により適した気温に維持されるので
ある。When the temperature inside the greenhouse 2 falls below the optimum temperature for crops (10°C to 40°C) at night and falls below the melting point of the heat storage material 13, the heat storage material 13 condenses and The heat stored in the heat storage material 13 is released as solidification heat, and the heat is efficiently conducted to the air passing through the heat storage device 4 via the inner tube 9 and the porous member 14, thereby increasing the temperature inside the greenhouse 2. This increases the temperature and maintains a temperature more suitable for crops.

ことができる。As shown in the embodiments above, the heat storage type greenhouse heating device of the present invention has the following features:
The heat storage material is made of a material that has a melting point around 10°C to 40°C, which is the optimum temperature for crops in the greenhouse, and is made of a heat storage material that transfers and receives a large amount of heat due to phase changes, so the temperature in the greenhouse is adjusted to the temperature of the crops. If the temperature exceeds the appropriate temperature of 100C to 40'C, the excess heat in the air inside the greenhouse can be efficiently absorbed as heat of fusion by the heat storage material, and the temperature of the heat storage device will be lower than the temperature inside the greenhouse. Since the temperature is maintained at a low temperature, the water vapor contained in the air in the greenhouse undergoes a phase change to water, and the latent heat of vaporization released at this time can also be absorbed and stored as heat of fusion by the heat storage material.

いて種々の構成が可能である。In addition, in the example, a porous member was used for the contact surface with the circulating air in the heat storage device, but for example, a multi-groove member using metal bellows for the inner tube of the heat storage device may also be used, and the material is limited to the example only. Rather, various configurations are possible without departing from the gist of the present invention.

果がある。As described above, according to the heat storage type greenhouse heating device of the present invention, not only the surplus heat of the sensible heat in the greenhouse during the daytime but also the latent heat of the water vapor impregnated in the air can be efficiently absorbed, so that the amount of heat required for heating can be efficiently absorbed. Therefore, there is a large energy saving effect in maintaining the temperature in the greenhouse at the appropriate temperature for crops at night.
