Description

  The present invention relates to a piping wiring information display device and piping wiring information display method for a multi-air conditioning system, and in particular, a piping wiring information display device for a multi-air conditioning system in which an outdoor unit and a plurality of indoor units are connected by piping wiring, and The present invention relates to a piping wiring information display method using this piping wiring information display device.

  In a building air conditioning system, a multi air conditioning system in which a plurality of indoor units are connected to one outdoor unit is employed in order to individually distribute indoor air conditioners and ensure a favorable indoor environment. The outdoor unit and the indoor unit connected to the outdoor unit constitute one piping system. In some cases, a plurality of outdoor units constitute a plurality of indoor units and a piping system, and a piping system for a plurality of air conditioning piping lines is provided in a building. In addition, since outdoor units are mainly installed on the roof, pipe pipes for equipment that penetrate in the vertical direction of the building are first used for piping wiring to indoor units installed on each floor. And the piping wiring in these pipe shafts branches for every floor, and is connected to a predetermined indoor unit using the ceiling back. Here, “piping wiring” means wiring and connecting an outdoor unit of an air conditioner and a connecting pipe of the indoor unit.

  FIG. 7 shows one embodiment of a multi-air conditioning system in which one outdoor unit and an indoor unit connected thereto are connected by piping wiring. Multi-air-conditioning system piping wiring diagram 30 shows a piping wiring system in which piping from one outdoor unit 2 to each indoor unit 3 by piping 6 is performed. The pipe 6 is branched by a branch joint (branch joint) 24 or a branch joint (branch header) 25 and connected to a plurality of indoor units 3. Hereinafter, these branch joints 24 and 25 are collectively referred to as a pipe joint 4. In the outdoor unit 2, the compressor 7 and the heat exchanger 8 are connected by the outdoor unit piping 9. Similarly, in the indoor unit 3, the compressor 12 and the heat exchanger 13 are connected by the indoor unit piping 14. In FIG. 7, this indoor unit internal pipe 14 is representatively displayed in one indoor unit 3.

  FIG. 8 is a partially enlarged view of the outdoor unit 2 shown in FIG. In the outdoor unit internal pipe 9, the gas pipe 10 and the liquid pipe 11 are paired to connect the compressor 7 and the heat exchanger 8. Similarly, the pipe 6 is also wired with a gas pipe 27 and a liquid pipe 28 as a pair. This wiring piping is the same in the indoor unit (not shown) 3. However, the gas pipes 10 and 27 and the liquid pipes 11 and 28 may be wired without being paired.

  In addition to the above-described branch joint (branch joint) 24 or branch joint (branch header) 25, the pipe joint 4 used for the pipe wiring of this multi air conditioning system includes various pipe joints 4. FIG. 9 shows a distributor 26 that is one type of the pipe joint 4. The distributor 26 is provided at a location where the pipes 6 from the two outdoor units 2 merge. This distributor 26 is also included in the pipe joint 4. Further, the pipe joint 4 includes a reducer (not shown) for connecting pipes having different diameters. That is, the pipe joint 4 referred to in the present invention is a generic term for joined parts for connecting pipes.

  The construction of the piping wiring of the multi-air-conditioning system means an operation in which an operator connects the outdoor unit 2 and the indoor unit 3 while connecting a copper pipe having a diameter determined in the field via a pipe joint. Moreover, when the design change of an installation generate | occur | produces, it means the operation | work which corrects piping wiring corresponding to it. Copper pipes are easier to bend than other pipes such as iron pipes and polyvinyl chloride pipes, so pipes may be wired at the site.

  Here, the recognition tag attached to the article includes a one-dimensional barcode, a two-dimensional barcode, a magnetic card, a contact IC card, a non-contact IC card, and the like. The non-contact IC card is defined as a wireless non-contact automatic recognition device, and refers to a device using RFID (Radio Frequency Identification) technology. What are called IC tags and ID tags are general names of non-contact type IC cards.

  In Patent Document 1, in a multi-air conditioning system in which a plurality of outdoor units and a plurality of indoor units are connected by a single communication network, each outdoor unit is connected to the same refrigerant system by operating each outdoor unit. It is disclosed that a temperature change of an indoor unit to be detected can be detected and automatically classified into an air conditioner group connected to a communication network. Thus, since the air conditioner group connected to the same refrigerant system becomes clear on the communication data, the conventional automatic address setting method can be applied to each group. As described above, in the multi-air conditioning system, an outdoor unit and an indoor unit system and addresses indicating installation positions in the system are attached. However, this address is an address for controlling the air conditioning system, and is not an address for piping wiring construction of the air conditioning equipment.

  A piping joint is used for piping wiring from one outdoor unit to an indoor unit belonging to the piping system by the multi-air conditioning system. Further, when a plurality of outdoor units are installed, a plurality of piping systems are used. For this reason, piping wiring of one system or wiring of a plurality of systems may be complicated. In particular, a large number of piping lines are mixed and wired in a pipe shaft that penetrates in the vertical direction of the building. In addition, branching of piping wiring to indoor units on each floor must be branched using many piping joints. Therefore, mistakes in piping and wiring are likely to occur at the site of facility construction.

  When this piping wiring error occurs, time is wasted in the system startup time before the trial operation of the air conditioning system, which causes a delay in the construction work of the equipment. In other words, if the air conditioning system is operated with a piping wiring error, the refrigerant does not flow into the indoor unit related to the piping wiring error, so the system abnormally stops. In some cases, this abnormal stop can be dealt with by reassigning the control address. In that case, the power of the multi-air conditioning system is temporarily turned off to change the address of the air conditioner, and then the power is turned on again to read the address. Therefore, these operations cause a significant delay in the construction work period.
