Description
BACKGROUND OF THE
Generally, the air conditioner circulates the refrigerant to cool and heat the indoor space. The air conditioner is divided into a single type air conditioner and a multi air conditioner according to the number of indoor units connected. In the single type air conditioner, one indoor unit is connected to the outdoor unit. In the multi-type air conditioner, a plurality of indoor units are connected to the outdoor unit.
The multi-type air conditioner is divided into a switching type air conditioner and a simultaneous type air conditioner according to a refrigerant flow method. The switching type air conditioner operates all the indoor units in the cooling mode or in the heating mode. The simultaneous air conditioner operates some of the indoor units in the cooling mode and some of the indoor units in the heating mode simultaneously.
The synchronous type air conditioner is provided with a distributor for distributing the refrigerant to a plurality of indoor units. The distributor distributes high-pressure refrigerant and low-pressure refrigerant to each indoor unit so that each indoor unit can operate in the cooling mode or the heating mode. A plurality of distributors may be arranged in the case of a large number of indoor units in a synchronous type air conditioner. At this time, a plurality of valves are arranged in each distributor, piping is connected to each valve, and indoor units are connected to each piping.
The above-described air conditioner is installed in a building and then commissioned before normal operation. A pipeline searching operation is performed to search which piping is connected to each indoor unit during the trial operation of the air conditioner. When the number of connections of the indoor units is large in searching for a pipe by the pipe search operation, it takes a long time to search for the pipe.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of searching for a pipe in an air conditioner that efficiently performs piping search in installation of an air conditioner.
Another object of the present invention is to provide a method of searching for a piping of an air conditioner that reduces the time required for pipeline search.
The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.
According to an aspect of the present invention, there is provided a method of searching for a pipe in an air conditioner, including a plurality of distributors, and a plurality of indoor units connected to the plurality of distributors, A group search for supplying a high-pressure refrigerant to any one indoor unit group among the plurality of indoor unit groups to search which one of the plurality of distributors is connected to the indoor unit group; Pressure refrigerant is supplied to each of the plurality of indoor units to perform an individual search for searching which of the plurality of indoor units is connected to which connection pipe of the distributor connected to the indoor unit group, and the group search is performed when the group search for one indoor unit group is completed And the individual search is performed on the other group of indoor units The grouping of the other indoor units is started simultaneously with the group search for the other indoor units.
According to an aspect of the present invention, there is provided a method of searching for a pipe in an air conditioner, including a plurality of distributors, and a plurality of indoor units connected to the plurality of distributors, The method comprising: supplying high-pressure refrigerant to the first indoor unit group of the plurality of indoor unit groups to search for which one of the plurality of distributors the first indoor unit group is connected to; The first indoor unit group and the second indoor unit group are connected to the first indoor unit group and the second indoor unit group, respectively, and when it is determined that the second indoor unit group is connected to the first indoor unit group of the plurality of indoor units, Pressure refrigerant is sequentially supplied to a plurality of indoor units belonging to the first indoor unit group, And a step of searching whether the each of the plurality of indoor unit groups connected to any connection piping of the first divider.
The details of other embodiments are included in the detailed description and drawings.
According to the piping search method of an air conditioner of the present invention, one or more of the following effects can be obtained.
First, there is an advantage of reducing the time required for searching for a group by searching for a group of indoor devices connected to a distributor and for searching for indoor units connected to indoor devices of a group of indoor devices connected to a connecting pipe of the indoor unit.
Second, there is also an advantage of reducing the time required for the pipeline search by performing the individual search for one indoor group and the individual search for another indoor group simultaneously.
Third, there is an advantage that it is possible to judge an error during the search of the pipe by judging whether the group search for the indoor unit groups and the individual search are performed at the same time and whether the search for the indoor unit group is completed or not.
The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.
