## Background
CROSS-REFERENCE TO RELATED APPLICATION(S)
This application claims priority under 35 U.S.C. §119 to Korean Application No. 10-2012-0135501 filed in Korea on Nov. 27, 2012, whose entire disclosure(s) is/are hereby incorporated by reference.
BACKGROUND
1. Field
Provided is an installation guide system for an air conditioner and a method of using the same.
2. Background
Installation guide systems for air conditioners and methods of using the same are known. However, they suffer from various disadvantages.
Air conditioners are home appliances that maintain indoor air into the most proper state according to use and purpose thereof. For example, such an air conditioner cools indoor air in the summer and heats indoor air in the winter. Furthermore, the air conditioner may control humidity of the indoor air and may purify the indoor air to provide a more pleasant and clean air.
In detail, the air conditioner has a refrigeration cycle in which compression, condensation, expansion, and evaporation processes for a refrigerant are performed. Thus, a cooling or heating operation of the air conditioner may be performed to cool or heat the indoor air according to the refrigeration cycle.
Such an air conditioner may be classified into a split type air conditioner in which indoor and outdoor units are separated from each other and an integral type air conditioner in which indoor and outdoor units are integrally coupled to each other as a single device, according to whether the indoor and outdoor units are separated from each other.
The outdoor unit includes an outdoor heat exchanger heat-exchanging with external air, and the indoor unit includes an indoor heat exchanger heat-exchanging with indoor air. The air conditioner may operate in a cooling mode or heating mode which are capable of being converted with respect to each other.
An air conditioner may be installed so that a plurality of indoor or outdoor units may be provided in one building. Particularly, in a case of a commercial air conditioner, high-capacity outdoor units may be disposed outside the building, and indoor units may be installed so that the indoor units are respectively disposed in a plurality of spaces of the floors.
In the air conditioner according to the related art, an adequate number of indoor or outdoor units may be provided in consideration of a size and structure of the building and the number of persons to be accommodated within the building so that the indoor or outdoor units are adequately designed in a building design phase to adequately locate the indoor or outdoor units in the building. Also, while the building is being designed, the adequate number of outdoor or indoor units should be selected in consideration of the conditions of the building. In addition, a position of a refrigerant tube, a branch tube, or drain tube and a constitution of a controller should be considered.
However, according to the process of designing the air conditioner in the building, a design drawing of the building and a design drawing of the air conditioner are drawn along different work flows. Thus, since the plurality of drawings may not match each other, it may be difficult to efficiently design the building and install the air conditioner.
Also, since communication between an installer and a user with respect to installation information (building information or capacity of the air conditioner) of the air conditioner may not effectively be performed, the number of outdoor and indoor units which are actually required may not be provided, or the refrigerant tube, and the like, may not be disposed in adequate positions in the building. Also, in the case where the air conditioner is not adequately installed in the building, cooling or heating efficiency of the air conditioner may be reduced during the operation thereof or may cause failures.
The above references are incorporated by reference herein where appropriate for appropriate teachings of additional or alternative details, features and/or technical background.
The details of one or more embodiments are set forth in the accompanying drawings and the description below. Other features will be apparent from the description and drawings, and from the claims.

The recommendation display part 270 may be a status bar, for example, that provides information regarding the available recommended configurations and enabling a selection of a configuration.
The pair of directional arrows 273 and 274 may include a first directional arrow 273 that may be selected for selecting a higher priority connection method and a second directional arrow 274 that may be selected for selecting a lower priority connection method on the basis of the recommended order. When the first and second directional arrows 273 and 274 are selected, the installed states of the connection tubes may be successively displayed (or changed) according to the set priority order.
For example, FIG. 11 illustrates a first connection method among six connection methods for connecting the first group of outdoor and plurality of indoor units to each other. Here, “1 of 6” may be displayed on the recommendation order display part 272. Also, the first outdoor unit display part 214a and a first recommendation tube 215a connecting the plurality of first indoor unit display parts 213a to each other may be displayed on the drawing display part 200.
If the second directional arrow 274 is selected once in the connection state of the tubes illustrated in FIG. 11, a second in order of the connection methods as shown in FIG. 12 may be displayed. Here, “2 of 6” may be displayed on the recommendation order display part 272.
Also, the drawing display part 200 may display the first outdoor unit display part 214a and a second recommendation tube 215b that connects the plurality of first indoor unit display parts 213a to each other. Of course, an extension shape of the second recommendation tube 215b may be different from that of the first recommendation tube 215a. 
If the second directional arrow 274 is selected once in the connection state of the tubes illustrated in FIG. 12, a third ranked connection method as shown in FIG. 13 may be displayed. Here, “3 of 6” may be displayed on the recommendation order display part 272.
Also, the drawing display part 200 may display the first outdoor unit display part 214a and a third recommendation tube 215c that connects the plurality of first indoor unit display parts 213a to each other. Of course, an extension shape of the third recommendation tube 215c may be different from those of the first and second recommendation tubes 215a and 215b. 
Thus, in the current embodiment, the six tube connection methods may be recommended through the above-described manner. Of course, the present disclosure is not limited to the number of recommended tube connection methods.
The user may select one tube connection method of the plurality of recommended tube connection methods. For example, when the confirmation arrow 275 is selected in a state where recommendation tube configuration is displayed on the drawing display part 200, the corresponding recommendation tube configuration may be applied as the connection tube configuration.
The six tube connection methods may be proposed as installable tube structures on the basis of the structure of the building, the capacity (performance) of the outdoor unit, the capacity (performance) of the indoor unit, or the load information of the room in which the indoor unit is installed. Here, the first in order of tube connection methods, e.g., the first recommendation tube 215a may be understood as the most adequate tube connection method in consideration of the costs and installation difficulty of the tubes.
Although the directional arrows 273 and 274 are disclosed as being selected to successively display the installed configurations of the recommendation tubes in the above-described embodiment, the present disclosure is not limited thereto. On the other hand, when the installed configuration according to the first priority order elapses for a set period of time, the installed configuration according to the second priority order may be automatically displayed on the drawing display part 200.
Moreover, although the installed configurations of the recommendation tubes may be manually or automatically and successively displayed in the above-described embodiment, the present disclosure is not limited thereto. On the other hand, the plurality of installed configurations (prior order and posterior order) with respect to the recommended tube configurations may be displayed on the drawing display part 200 at the same time.
FIG. 14 is a perspective view of the installation guide system in which the outdoor and indoor units are connected to each other through a connection tube according to an embodiment. A first connection tube 216a that connects the first group of outdoor and indoor units 214a and 213a to each other and a second connection tube 216b that connects the second group of outdoor and indoor units 213b and 214b to each other may be provided. For example, FIG. 14 illustrates a perspective view of a structure of the building and an installation configuration of the air conditioner having a plurality of groups.
The first connection tube 216a may be one connection method of the plurality of connection methods recommended with respect to the first group of outdoor and indoor units 214a and 213a, and the second connection tube 216b may be one connection method of the plurality of connection methods recommended with respect to the second group of outdoor and indoor units 214b and 213b. Thus, the plurality of indoor units disposed within the rooms of the building and the outdoor unit matching the plurality of indoor units may be connected to the each other through the connection tubes. As a result, it may be unnecessary to separately design the connection tubes for multiple groups by the user. Thus, since one connection method of the tube connection methods recommended in the system 10 may be selected, the tube installation may be easily performed.
FIG. 15 is a plan view of the installation guide system in which the outdoor and indoor units are connected to each other through a connection tube according to an embodiment, and FIG. 16 is a front view of the installation guide system in which the outdoor and indoor units are connected to each other through a connection tube according to an embodiment.
