Abstract

PURPOSE:To provide a hydroculture system designed so that a latent heat-type heat storage material with its heat release temperature approximately constant is made into pellets, which are then incorporated into porous balls, and the heat release of the heat storage material is utilized for the temperature control, thereby making a temperature controller such as a heater needless. CONSTITUTION:Heat storage pellets 6 are mixed with porous balls 1 and the resultant mixture is put into an inside pot 2 which is housed in an outside pot 3 with its bottom provided with a culture solution 4. The pellets 6 can be prepared by impregnating or swelling a carrier with a latent heat-type heat storage material followed by making the resultant product or the material itself into pellets and then coating the pellets with a substance capable of preventing the heat storage material from exuding. Thereby, the pellets into which heat has been stored through sunlight in the daytime is spontaneously subjected to phase transformation after sunset, resulting in heat release. Because of a latent heat-type heat storage material, this material is constant in heat release temperature. Therefore, as the pot will be kept at constant temperature in the above-mentioned phase transformation, not only heat retentive effect but also temperature control can be accomplished.

にも清潔なものである。As shown in Figure 2, hydroculture is carried out in the inner pot.
A porous ball, such as a foam brick, is placed inside the pot, and the porous ball sucks up the culture solution supplied to the bottom of the outer pot, thereby replenishing water to the plants and allowing them to grow. Since it is unnecessary, it is easy to manage and looks clean.

することを目的としている。However, hydroculture requires a temperature control device with a built-in heater etc. for temperature control (especially at night in winter), which increases equipment costs. Therefore, the present invention attempts to use a latent heat storage material whose heat radiation temperature is almost constant in the form of pellets and mix it into a porous pole, and utilize the heat radiation of the heat storage material for temperature control. The purpose is to provide a hydroculture system that does not require any equipment.

たす蓄熱ペレット量を供給してやれば良い。In order to achieve the above object, in the nodroculture system of the present invention, a heat storage pellet (2) is mixed into a porous ball (2) and placed in an inner pot (2). This inner pot (■) is placed inside an outer pot (■) containing a culture solution (■) at the bottom. These heat storage pellets (■) are made by impregnating or swelling a carrier with latent heat storage material, or by making the latent heat storage material itself into pellets and coating it with a substance that can prevent the heat storage material from seeping out. As heat storage pellets for mixing,
As described in No. 99, heat storage pellets obtained by spray coating a wax barrier resin on crosslinked polyethylene pellets impregnated with a latent heat storage material may be suitable. As for the mixed amount of heat storage pellets (2), the required amount of latent heat is calculated from the pot capacity, heat dissipation time, and outside air temperature, so it is sufficient to supply the amount of heat storage pellets that satisfies the amount of latent heat.

潜熱蓄熱材が相変態中の体内温度は一定であるので温度
管理が可能である。When plants are grown in the hydroculture system configured as described above, the heat storage pellets that have been stored in sunlight during the day will undergo phase transformation and release heat after sunset. Since the heat storage material contained in the heat storage pellet is a latent heat storage material, the heat radiation temperature is constant. Therefore, during the phase transformation of the heat storage material, the inside of the body is kept at a constant temperature, so it not only has a heat retention effect, but also
Temperature control is also possible. Furthermore, during heat storage, the temperature inside the body remains constant while the latent heat storage material undergoes phase transformation, so temperature control is possible.
