PURPOSE: An adsorbent unit for a refrigerant accumulator is provided which has a housing with a bottom wall and a side wall and a U-shaped pipe with a return bend adjacent the bottom wall and with first and second pipe portions extending from the return bend along the side wall, and a filter body extending outwardly from the return bend. CONSTITUTION: An adsorbent unit 10a has a separate refrigerant tracer compartment(70) which is immediately adjacent to the container(71) which contains molecular sieve adsorbent(72), and the tracer compartment contains a tracer wafer(90) isolated from the adsorbent(72). The adsorbent unit 10a is formed of porous material, heat-fusible polyester. The adsorbent unit 10a is formed from two sides of felted polyester, which are bonded to each other by fused seams. The container(71) has a pronounced convex side(73) and a less pronounced convex side(74). A compartment(70) also has at least one convex side. The adsorbent container(71) is bounded by fused seams(75,77,79,80) which also forms a seam of tracer compartment(70). Seam(80) includes straight portions(81) and(82) and circular portion(83). The refrigerant tracer compartment(70) includes fused seam(83) and fused seam(84) which joins seams(81) and(82). A tab 15a extends outwardly from seam(75). Tab 15a may be identical in all respects to tab(15). A tab 14a extends outwardly from the opposite side of the adsorbent unit from tab 15a. The adsorbent unit includes fused seams(85,87) on opposite sides of unfused portion(89). The ends of fused seam(87) merge into fused seams(77,79), and the ends of fused seam(85) merge into seams(81,82).
