<p>A first joint block 30 and a second joint block 40 are connected to an end of a refrigerant inlet pipe 6a and that of a refrigerant outlet pipe 6b, respectively. Both the joint blocks 30 and 40 are connected each other. A predetermined face of the first joint block 30 constitutes a first flange face 31, and a face of the second joint block 40 facing toward a direction different from the predetermined face constitutes a second flange face 41. At the end of a first external pipe 50a and that of a second external pipe 50b, flange members 51a and 51b are attached. When connecting these flange members, the first and second external pipes 50a and 50b are connected to the joint blocks 30 and 40 from different directions. <IMAGE></p> |
