[Embodiment 1] Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the overall configuration of a regenerative air conditioner according to claims 1 to 3 of the present invention. In the figure, 6 is a compressor, 7 is a condenser, 8 is a first pressure reducing mechanism, 9a is a first evaporator, 1
0 is an accumulator, and by connecting sequentially,
A general cooling circuit is formed. 9b is a second evaporator, 11 is a refrigerant gas pump, 12 is a heat storage material such as water stored in a heat storage tank 13, 14 is a heat storage heat exchanger installed in the heat storage tank, and 15 is This is a second pressure reducing mechanism. By connecting the refrigerant gas pump 11, the heat storage heat exchanger 14, the second pressure reducing mechanism 15, and the second evaporator 9b, a cooling circuit is formed. FIG. 2 is a perspective view showing the heat storage heat exchanger 14. In the figure, 16 is a heat transfer tube formed in a coil shape, 17 is a support member which abuts the heat transfer tube and is fixed at a stable pitch, 17a is a cutout portion of the support member, 18 is a support member fixed and tension is applied to the heat transfer tube. It is a support frame that has By fixing the support member 17 to the support frame 18, the heat transfer tube 16 is turned into the notch 17 a of the support member 17.
And is fixed at intervals of the notch portions 17a . Assembly is performed as follows. First, the support frame 18 is assembled.
Next, the support member 17 is fixed on the upper part of the support frame 18 . Next, the upper end 16 a of the heat transfer tube 16 is fitted into the notch 17 a of the support member 17. At this time, the heat transfer tube 16 is suspended in the air. Next, the support member 17 is passed through the heat transfer tube 16 . Next, the lower end 16 b of the heat transfer tube 16 is fitted into the notch 17 a of the support member 17. Next, the support member 17 is fixed to the support frame 18. Thereby, both ends 16 of the heat transfer tube 16
The heat transfer tubes 16 are fixed to the upper and lower portions of the support frame 18 with tension by contacting the notches 17a of the support member 17 with the notches 17a and 16b. If the heat transfer tube 16 in contact with the support member 17 is pulled too much, the heat transfer tube 16 may be flattened or distorted. Conversely, if the tension is insufficient, the heat transfer tube 1
6 may be shifted. Therefore, the support member 1
The heat transfer tubes 16 can be fixed at a stable pitch by adjusting the vertical distance between the support frame 7 and the support frame 18 to provide an appropriate tension. That is, as shown in FIG. 3, when fixing the support member 17 to the support frame 18, an elongated hole 19 is provided in the support member 17, and the fixing screw 2 is inserted into the elongated hole 19.
Insert 0. Therefore, when the fixing screw 20 is loosened, the support member 17 can be slid up and down. Alternatively, as shown in FIG. 4, the support member 17 supporting frame 1
8 , the height adjusting member 21 may be inserted.

Embodiment 2 Hereinafter, Example 2 of the present invention will be described with reference to FIG.
A description will be given based on FIG. As shown in FIGS. 5 and 6, a pair of support members 17 is brought into contact with a coil-shaped heat transfer tube 16 reciprocating about 10 to 20 times, and a support frame 18 is fixed.
One heat exchange block 22 is formed. Then, the support frames 18 are joined together in the front-rear and left-right directions in accordance with the heat exchange amount of the heat storage to constitute a plurality of heat storage heat exchangers 14 having a desired heat exchange amount. Thereby, the heat exchange block 2
The overall shape can be arbitrarily determined depending on how the two are connected, and the problem of the setting space is alleviated. Further, since the same member is used, parts can be shared and the assembling method can be simplified. In the above-described embodiment, the support member 17 has a cutout 17a in a semicircular shape. However, the stopper 17b is provided in the cutout 17a as shown in FIG. Detachment can be eliminated.

Embodiment 3 FIG. Hereinafter, Embodiment 3 of the present invention will be described with reference to FIG.
It will be described based on. In FIG. 8, when the heat transfer tube 16 is in contact with the support member 17, a thick support member 17 is used to avoid concentration of stress on the heat transfer tube 16. The upper and lower edges of the support member 17 are alternately staggered and provided with a plurality of notches 17 a in accordance with the pitch of the heat transfer tubes 16. Since the heat transfer tubes 16 are supported in a staggered manner, the cutout portions 17a of the support members 17 need to be slanted, and the support members 17 of the first and second embodiments are different in upper fixing and lower fixing. However, the support member 17 of the third embodiment requires the use of the support member 1.
By inverting 7, the heat transfer tube 16 can be used for both upper fixing and lower fixing, and the upper and lower support members 17 are shared.
