  In the above-mentioned Patent Document 1, a quick fastener and a holding metal fitting are required to support the outdoor unit in a state where the main pipe connection portion of the forward header and the first pipe are connected. In addition, a quick fastener and a holding metal fitting are also required to support the outdoor unit in a state where the main pipe connection portion of the return header and the second pipe are connected. That is, four members (two quick fasteners and two presser fittings) are required to support the forward header and the return header on the outdoor unit.

  Accordingly, the present invention has been made to solve the above-described problems, and provides a header support structure capable of reducing the number of parts required to support the forward header and the return header. With the goal.

A header support structure according to a first aspect of the present invention is a header support structure in an outdoor unit connected to a temperature control device via a forward pipe and a return pipe, and the first pipe whose position is regulated in the outdoor unit is A forward header having a first piping connection portion to be connected and a forward piping connection portion to which the forward piping is connected, and a valve mechanism disposed therein; and a second piping whose position is regulated in the outdoor unit A return header having a second pipe connection part to which the return pipe is connected, a return header to which the return pipe is connected, and the forward header in a state where the first pipe is connected to the first pipe connection part. And a support member for supporting the return header to the outdoor unit in a state in which the second pipe is connected to the second pipe connection portion . 1 piping and the support member While being held by, the return header, it characterized in that it is clamped between the support member and the second pipe.

By continuously performing such operation, floor heating operation can be performed. In this embodiment, floor heating is mainly described. However, if the outdoor heat exchanger 19 functions as a condenser and the water heat exchanger 16 functions as an evaporator, the circulating liquid 8 is Since it is cooled, the floor cooling operation can also be performed. Furthermore, by opening both of the electric expansion valves 29 and 30 on both sides of the indoor unit 18 and the temperature control unit 1, it is possible to simultaneously heat and cool the room and the floor.

[Characteristics of header support structure of this embodiment]
The header support structure 100 of this embodiment has the following characteristics.

  In the header support structure 100 of the present embodiment, by using the support plate 5, the forward header 4 is supported by the outdoor unit 50 (header chamber 1 b) in a state where the first pipe 10 and the main pipe connection portion 4 b are connected. In addition, the return header 6 can be supported by the outdoor unit 50 in a state where the second pipe 12 and the main pipe connection portion 6b are connected. In other words, in this embodiment, the forward header 4 and the return header 6 can be supported by the outdoor unit 50 by the single support plate 5 without using a quick fastener or a presser fitting. As a result, the common support plate 5 can be used to support the forward header 4 and the return header 6, and the number of parts can be reduced.

  In the header support structure 100 of the present embodiment, since the forward header 4 and the return header 6 are both made of resin, the forward header 4 and the return header 6 are different from the case where the forward header 4 and the return header 6 are formed of metal. Dimensional errors caused by the above can be reduced. This makes it possible to form the support plate 5 in accordance with the dimensions of the forward header 4 and the return header 6, and the forward header with the first pipe 10 connected to the main pipe connecting portion 4b by one support plate 5. 4 is supported by the outdoor unit 50, and the return header 6 can be supported by the header chamber 1 b of the outdoor unit 50 in a state where the second pipe 12 is connected to the main pipe connection portion 6 b. Therefore, compared with the case where the forward header 4 and the return header 6 are supported by separate members, the number of parts required to support the forward header 4 and the return header 6 can be reduced. Further, as the number of parts required to support the forward header 4 and the return header 6 is reduced, the work process for supporting the forward header 4 and the return header 6 to the outdoor unit 50 is reduced. Further, as described above, the forward header 4 and the return header 6 are made of resin, so that the forward header 4 and the return header 6 made of metal accompanied by brazing work, welding work, etc. are manufactured compared to the case where the forward header 4 and the return header 6 are manufactured. The cost of the header 4 and the return header 6 can be reduced.

  Further, in the header support structure 100, the main pipe connection portion 4 b of the forward header 4 and the first pipe 10 can be reliably connected by sandwiching the forward header 4 between the first pipe 10 and the support plate 5. it can. For this reason, without using the member (for example, quick fastener) with which the main pipe connection part 4b of the going header 4 and the 1st piping 10 are attached, the main pipe connecting part 4b of the going header 4 and the 1st pipe 10 are used. Connection failure can be prevented. Similarly, for the return header 6, the main pipe connection portion of the return header 6 can be used without using a member (for example, a quick fastener) attached to the connection portion between the main pipe connection portion 6 b of the return header 6 and the second pipe 12. Connection failure between 6b and the second pipe 12 can be prevented.

  In the header support structure 100, the rib 6e abuts the support plate 5 with the protruding portion 6d of the header 6 inserted into the through hole 5e of the support plate 5. The structure clamped with the piping 12 and the support plate 5 is easily realizable. In the configuration in which the protruding portion 6 d of the return header 6 is inserted into the through hole 5 e of the support plate 5, the return header 6 can rotate around the axis of the protruding portion 6 d. Therefore, the attachment angle of the return pipe 3b connected to the branch pipe connection portion 6c of the return header 6 can be adjusted, and the pipe can be arranged so that the stress applied to the return pipe 3b is reduced. Therefore, the optimum piping according to the position of the return piping 3b connected to 2 is possible, and versatility and convenience are improved.

  Further, in this header support structure 100, even when the return pipe 3b burns due to fire, etc. and the return header 6 connected to the return pipe 3b spreads, the forward header 4 disposed above the return header 6 However, it is possible to suppress burning due to the stagnation fire related to the return header 6. Furthermore, it is possible to prevent the thermal valve 15 provided inside the forward header 4 from burning.

  Further, in this header support structure 100, the forward header 4 is disposed above the return header 6, and the branch pipe connection portion 4 c of the forward header 4 is downstream of the branch pipe connection portion 6 c of the return header 6 in the pipe connection direction. The branch pipe connection portion 4c of the forward header 4 and the branch pipe connection portion 6c of the return header 6 are arranged at a position shifted from the operator. Therefore, the attachment of the forward piping 3a and the return piping 3b is improved for the operator.
