It may be partitioned into a large number of sections in a grid pattern. This internal partition restricts the movement of the medium within the main body 51, and also controls the thickness of the bag, facilitating heat transfer between the media. Further, even if the bag-like main body 51 should break, the outflow of the medium can be kept to a minimum. A hook 55 for hanging the main body 51 in the heat storage air chamber B is provided at one end edge of the bag-like main body 51.

加熱される。 During daytime sunshine, the air inside greenhouse A is warmed. The hottest air is then concentrated near the central ceiling. At this time, by rotationally driving the fan 2, the heated air is guided into the heat storage air chamber B through the vertical ventilation cavity 11. When the temperature inside the heat storage air chamber B reaches 30°C or higher, the heat storage body 5
The phase change heat storage medium 53 inside absorbs heat, decomposes, and stores heat. The cold air from which heat has been removed is returned into the greenhouse A through the exhaust port on the other side of the greenhouse and heated again by solar heat.

る。 At night and during rainy weather, the temperature inside the greenhouse is 27-30℃
If the temperature becomes below, inside the bag-like main body 51,
CaCl 2 combines with water to generate heat, which is radiated into the heat storage air chamber B, and as the fan 2 operates, the hot air in the heat storage air chamber B is sent through the exhaust port into the greenhouse A to be warmed. Therefore, no other heating is required while the phase change heat storage medium 53 is dissipating heat. Therefore, heating by other means only needs to be used for a short period of time, such as during extremely cold seasons or when rain continues for a long period of time.

きることとなつた。 As described above, the present invention provides a heat storage air chamber partitioned by transparent plastic sheets inside the greenhouse in close proximity to and parallel to the north wall, and an air collection chamber that is opened to the upper part of the greenhouse at the top of the heat storage air chamber. A heat duct is connected to the heat storage air chamber, and an exhaust port is provided at the lower part of the heat storage air chamber. Alternatively, sag-like heat storage bodies are installed in parallel. Then, solar heat during sunlight is introduced into the heat storage air chamber, where multiple heat storage bodies store heat, and this accumulated heat can be released when the outside temperature drops and the indoor temperature falls below a certain temperature. This is a possible configuration.
Therefore, the mechanism is simple, the heat absorption efficiency is high, and a large amount of heat can be absorbed and stored. As a result, only a small amount of heating is required due to heat radiation, resulting in significant savings in fuel costs.

High heat absorption and heat dissipation efficiency.
そのうえ、蓄熱体は取外し自在とされているの
で、夏季など、蓄熱が不要な時期には撤去するこ
ともでき、温室内の整理がやり易い。 Furthermore, since the heat storage body is removable, it can be removed during seasons such as summer when heat storage is not required, making it easier to organize the inside of the greenhouse.
