Reference numeral 100 denotes a whole liquid reservoir including a body 110 having a bottomed cylindrical reservoir and a disk-shaped head seat (header) that can seal the opening portion 112 of the lower end portion of the body 110. ) 120. The bottom portion 114 on the opposite side (the upper end portion of the figure) of the opening portion Π2 of the body 110 is formed as a thick portion, and can be used to increase its rigidity. As shown in FIG. 2, a bag 130 (shown in FIG. 2(b)) enclosed in a body n〇 (shown in FIG. 2(a)) is folded, for example, by a plastic non-woven fabric, and then heated. It is formed by sealing or sewing its peripheral edges 132a, 132b, 132c. A desiccant 134 is enclosed in the bag body 130. Since the bag body 13 is made of a plastic non-woven fabric having a gap through which the liquid can pass, the refrigerant stored in the body 110 is in contact with the desiccant 134 in the bag body 130, and is contained in the refrigerant. The water in the water is adsorbed by the desiccant 134. A thin wall portion 126 is formed on the opposite end surface of the body 11 () shown in the head holder 120 (shown in Fig. 2(d)). Inside the wall portion 126, a filter 11140 (shown in Fig. 2 (4)) for trapping cold matter is inserted, and the caulking processing portion K1 is fixed to the headstock 12 (). The filter 14 〇 097150208 200940925 is formed by processing the mesh-shaped metal disk into a medium-high shape, and has a function of capturing and removing foreign matter in the refrigerant from the inside of the body 110 toward the outflow hole 124. When the accumulator 1 is assembled, the bag body 130 is sealed in the body 11b, and the headstock 120 is inserted into the opening portion 112 of the body 110, and joined by the arc welding process W1. The filter 140 is attached in advance to the headstock 120 by the caulking portion K1. The accumulator 1 is equipped in the air conditioning system in such a manner that the inflow hole 122 and the outflow hole 124 of the refrigerant face downward. Fig. 3 is a longitudinal cross-sectional view showing the main portion of the first embodiment of the accumulator according to the present invention, wherein Fig. 3(a) is a cross-sectional view taken along the line A-A in the upper portion (b) of Fig. (a). The main body 110, the headstock 120, the filter 140, the desiccant 134, and the like are the same as those shown in Figs. 1 and 2, and therefore, the description thereof will be omitted. In the first embodiment, the concave portion 10 capable of accommodating the fluorescent agent 1 is formed at a position farthest from the inflow hole 122 and the outflow hole 124 around the upper portion of the headstock 120 as a holding means for holding the fluorescent agent 1. That is, in the circumferential surface of the headstock 12, as shown in Fig. 3 (a), the inflow hole 122 and the outflow hole 124 are formed with a concave portion 1 centered at a position intersecting at 90 degrees (the front end is due to the relationship of the holes). Cheng - is conical). The fluorescent agent 1 (the fibrous material impregnated with the fluorescent agent) is attached to the concave portion 10 in a state where it is fitted, and in this state, it is held in the concave portion 10. Since the concave portion 10 is formed to face the cylindrical inner surface of the body 11A, the cylindrical inner surface of the body 110 is located on the outer side closest to the fluorescent agent i. Therefore, the fluorescent agent 1 does not fall off from the headstock 120 due to carelessness from the recess 10 of the headstock 12 at least at the original size. The refrigerant flowing into the 097150208 7 200940925 from the inflow hole 122 is decomposed by contact with (4) m, and the micro (tetra) particles flow out from the outflow hole 124 and the refrigerant to the outside of the accumulator 100 to circulate in the refrigeration cycle. Further, the outer peripheral edge portion 141 of the filter 140 is fixed to the headstock 120 by the slit π. 4 is a longitudinal cross-sectional view showing the main portion 12 of the second embodiment of the accumulator according to the present invention, which is formed at the inner end portion of the view 120; and the top portion 151 is formed with the concave portion 20 as the fluorescent portion.
