る。Next, a means for knowing the heat storage amount in each tank (11), (12), (13), (14) will be described. As shown in Fig. 2 (a) and (b), the inner surface of the outer wall (11A), (12A), (13A), (14A) of each tank (11), (12), (13), (14) A concave portion is formed in the concave portion, and a mounting base (6) to which a detecting body (3) such as a piezoelectric element is fixed is mounted in the concave portion. On the other hand, the heat storage tank (11),
The latent heat storage bodies (1) in (12), (13) and (14) are closely arranged so that the lateral sides of long width are in contact with each other, and the protrusions (1a) of those lateral sides actually contact each other. Thus, a flow path for the heat transfer fluid is provided. Therefore, as shown in (b) of FIG. 2, when the heat storage starts from the state before the heat storage starts, each latent heat storage body (1) becomes a phase of the latent heat storage material as shown in (a) of FIG. Volume expansion is performed by the change. Then, the latent heat storage body (1) located on the outermost side of the latent heat storage body (1) group, which is the detection target of the detection sensor (3) as the detection body, expands its own volume and is adjacent to another latent heat storage body. When the body (1) receives a moving force in the close direction due to the volume expansion, the body (1) approaches the detection sensor (3) and comes into contact with the detection sensor (3) at a set heat storage amount. Therefore, it is possible to perform ON-OFF control for stopping the operation of the heat pump by receiving the signal from the detection sensor (3) and determining that the set heat storage amount has been reached. However, the mount (6) to which the detection sensor (3) is fixed is made of resin, and when the latent heat storage body (1) swells by a set amount or more, it is elastically deformed so as to absorb the swelling amount. To do.
