る。 BACKGROUND ART Conventionally, a liquid storage tank is provided in the underground part of a building, and a piping system for passing a first heat medium is installed in this tank, and a second heat medium is stored, and a second heat medium is supplied through the piping system. A first heat medium and a second heat medium liquid are exchanged with each other, and the second heat medium is
An air conditioning system for a building has been proposed in which a heating medium liquid is supplied into the building and circulated between the supply area and the tank. This system includes a first heat exchange system formed by a first heat medium and a second heat medium liquid, and a second heat exchange system.
It is a composite heat exchange system consisting of a second heat exchange system formed by a heat medium liquid and the supply area, and when the second heat exchange system is unused, the second heat medium liquid is transferred to the target area (supply area ), it has the advantage that it can be used as a heat storage system that operates only the first heat exchange system and stores heat in the second heat medium liquid in the liquid storage tank.

的には有利であることが判明した。 The present inventors have developed an in-tank piping structure for the first heat exchange system in the composite heat exchange device, which is applicable not only to air conditioning systems for buildings, but also to air conditioning systems for ships, outdoor structures, and liquid supply systems. As a result of intensive research to develop the pipe, we found that a pipe made of organic polymer was used to communicate between the header pipes, but although it had poor heat exchange performance, it was difficult to use chemically It was found to be advantageous in terms of overall evaluation, including stability and pipe stress related to weight in liquid.

部処理が新たな課題として出現した。 As a result, it became necessary to separately devise measures to increase the heat exchange efficiency of the piping. Making the pipe thinner as a means of achieving this is advantageous because it improves the heat exchange properties of the pipe itself, but there is a limit due to the strength required of the pipe. Therefore, the piping configuration had to be devised. We have found that this problem can be solved by creating dense piping using small-diameter pipes, but in order to advantageously perform such dense piping, we need a piping structure with excellent workability, especially header pipes. A new issue has emerged: the treatment of the ends of pipes that connect to the pipes.
