採用される。In this invention, when cold heat is stored in the heat storage material, the freezing point and melting point of the heat storage material are lowered by addition of water, and when warm heat is stored in the heat storage material, the freezing point and melting point of the heat storage material are increased by dehydration. deep. Polyhydric alcohol such as polyethylene glycol is preferably used as the heat storage material, and the addition or dehydration of water to such heat storage material uses a natural hydrogenation method that utilizes the difference in humidity between summer and winter. A dehydration method is adopted.

じにくくなる。FIG. 1 is an explanatory view of a natural hydrogenation / dehydration method. In this case, the heat storage material H is stored in the case 6, and the plate 7 made of a porous separation membrane is provided in the case 6.
Is attached. As the porous separation membrane, one having a property of allowing water vapor to pass therethrough but not allowing the liquid heat storage material H or water to pass therethrough is used. According to this, when the relative humidity is high, such as in the summer, a large amount of water is correspondingly stored in the heat storage material H.
Are absorbed by the heat storage material H and the freezing point and melting point of the heat storage material H are lowered. On the contrary, when the relative humidity is low like in winter, the heat storage material H releases water to increase the freezing point and the melting point of the heat storage material H. Since polyethylene glycol used in the heat storage material H has excellent compatibility with water, water is evenly distributed in the heat storage material H, and variations in the freezing point and melting point hardly occur throughout the heat storage material H.

冷房適温や暖房適温を容易に得ることが可能になる。As described in FIG. 2, when the water content of the heat storage material H increases, the freezing point and melting point of the heat storage material H decrease. Therefore, by storing cold heat in the heat storage material H having the melting point shown by point B in FIG. 2 and radiating the cold heat, it is possible to obtain a suitable cooling temperature in the summer. Further, when the water content of the heat storage material H decreases, the freezing point and melting point of the heat storage material H rise. Therefore, by accumulating warm heat in the heat storage material H which has reached the freezing point shown by the point A in FIG. 2 and radiating the heat, a suitable heating temperature in winter can be obtained. FIG. 3 shows the moisture absorption amount of polyethylene glycol (PEG1500). As is clear from this, the moisture absorption of PEG1500 is 30 to 40% in the summer, which absorbs a large amount of water, and 2% in the winter, which hardly absorbs water. Therefore, when polyethylene glycol is used as the heat storage material H, it becomes possible to cause a large difference in the freezing point and the melting point between the summer and winter.
It is possible to easily obtain the optimum temperature for cooling and the optimum temperature for heating.

施例と併用するのに好ましい方法である。By the way, in order to obtain the optimum cooling temperature and the optimum heating temperature by utilizing the method of the present invention, it is necessary to appropriately control the changes in the freezing point and the melting point of the heat storage material due to hydrogenation and dehydration. As shown in FIG. 2, there is a certain correlation between the water content of the heat storage material and its freezing point and melting point. Therefore, by knowing the water content, the freezing point and melting point at that time can be known. . Generally, a hydrometer and an optical sensor are often used as a means for knowing the water content, that is, the heat storage material concentration, but they have the drawback of being expensive. Therefore, a method by which the heat storage material concentration can be easily known will be described below. This method is intended to know the concentration of the heat storage material based on the weight change of the heat storage material due to hydrogenation / dehydration, and is a preferable method to be used in combination with the above embodiment.

Absorbs atmospheric moisture and increases its weight. When the vacuum pump P is operated, the internal space of the porous separation membrane tube 13 is sucked through the suction pipe 14, the internal pressure becomes lower than the internal pressure of the heat storage material H, and the heat storage material H absorbs it. The water it contains is dehydrated. Then, when the water content of the heat storage material H increases or decreases, the weight sensor S detects a change in weight of the heat storage material H accompanying it. Therefore, when an electric signal is output from the weight sensor S and the vacuum pump P is ON-OFF controlled by the signal, the water content of the heat storage material H is controlled within a certain range, and it is possible to maintain a suitable heating temperature and a suitable cooling temperature. is there.
