CHANNEL SWITCHING SET UNIT AND CHANNEL SWITCHING SET UNIT MANUFACTURING METHOD

摘要

An intermediate unit (130) is disposed between an outdoor unit (110) and a plurality of indoor units (120) and is configured and arranged to switch flow of refrigerant. The intermediate unit (130) includes a plurality of first units (71) and a plurality of liquid communicating units (73). The first units (71) are connected to a high-low pressure gas communicating pipe (13) and a suction gas communicating pipe (12), both of which extend from the outdoor unit (110). Every adjacent two of the first units (71) extends approximately in parallel to each other at a predetermined first distance (dl). Each of the liquid communicating units (73) is connected at one end to a liquid communicating pipe (11) extending from the outdoor unit (110), and is connected at the other end to a liquid pipe (LP) extending to each of the indoor units (120). Every adjacent two of the liquid communicating units (73) extends approximately in parallel to each other at the predetermined first distance (dl). The first units (71) and the liquid communicating units (73) are alternately disposed.
