<Indoor unit placement method>
In the arrangement method of the EHP indoor unit and the GHP indoor unit, first, a lattice diagram for arranging the indoor units is created, and the indoor unit is arranged on the intersection of the lattice diagrams. That is, the air conditioner arrangement support system 1 according to the present embodiment determines the arrangement location of the indoor unit on the plan view of the space and then arranges the EHP indoor unit in which arrangement location, or in the GHP room in which arrangement location. An arrangement pattern indicating whether the machine is to be arranged is derived. The “lattice diagram” here is a diagram composed of a plurality of vertical lines arranged at predetermined intervals and a plurality of horizontal lines intersecting perpendicularly to the vertical lines and arranged at predetermined intervals. In addition, the intersection of the vertical line and the horizontal line is called a grid point.

  Hereinafter, description will be made in the order of a method for creating a lattice diagram and a method for arranging indoor units.

(1) Method for Creating Lattice Diagram FIG. 3 is a flowchart showing a flow for creating a lattice diagram. Hereinafter, a method for creating a lattice diagram will be described with reference to FIG. FIG. 4 is a plan view of a space (a wall W1 as a boundary of the space in a top view), and is a reference diagram for explaining a lattice diagram creation flow.

  In step S1, the area (unit air-conditioning area) in which one indoor unit air-conditions is calculated from the floor area of the space and the number of indoor units. Note that the floor area of the space and the number of indoor units are based on information input by the customer in advance on the space information input screen SC1 described later. When step S1 ends, the process proceeds to step S2.

  In step S2, the square root of the unit air conditioning area is calculated as the first indoor unit interval a1. In step S2, the calculated first indoor unit interval a1 is a value obtained by rounding off the value of the square root of the unit air-conditioning area to the nearest decimal place. In addition, although the 1st indoor unit space | interval a1 is made into the value which rounded off the value of the square root of a unit air-conditioning area to the place below a decimal point here, it is not limited to a rounding off, it rounds down below a decimal point, or rounds up below a decimal point It doesn't matter. In addition, the rounding position may not be a decimal point. When step S2 ends, the process proceeds to step S3.

  In step S3, a square lattice whose one side length is the first indoor unit interval a1 is drawn as the first indoor unit arrangement lattice Gr1 (see FIG. 4). When step S3 ends, the process proceeds to step S4.

  In step S4, it is confirmed whether the number of indoor units is an odd number or an even number. If the number of indoor units is an odd number, the process proceeds to step S5, and if the number of indoor units is an even number, the process proceeds to step S8 (in the example of FIG. 4, the number is 18 and is an even number, so the process proceeds to step S8). become). In step S5 and step S8, the first indoor unit arrangement grid Gr1 drawn in step S3 is positioned in the plan view of the space. The method of positioning the first indoor unit arrangement grid Gr1 in the plan view of the space differs depending on the number of indoor units, and is divided into a case where the number of indoor units is an odd number and a case where the number is an even number. For this reason, in step S4, when the number of indoor units is an odd number, the process proceeds to step S5, and when the number of indoor units is an even number, the process proceeds to step S8. Here, the description with reference to the drawings is performed only when the number of indoor units after step S8 is an even number, and is omitted when the number of indoor units after step S5 is an odd number.

  In step S5, the first indoor unit arrangement grid Gr1 is arranged such that the grid points coincide with the center of gravity G1 of the plan view of the space (first grid arrangement pattern). The lattice point that coincides with the center of gravity G1 is referred to as a first center point. That is, in step S5, since the number of indoor units is an odd number, the first indoor unit placement grid Gr1 is positioned so that one indoor unit is always placed at the center of gravity G1 of the plan view. The first indoor unit arrangement grid Gr1 is created so that the horizontal line thereof coincides with the east-west direction of the plan view of the space. When step S5 ends, the process proceeds to step S6.

  In step S6, the first indoor unit arrangement grid Gr1 in the first arrangement pattern is rotated from 0 degrees to 85 degrees by an angle of 5 degrees from the first center point, and the first indoor unit arrangement grid with respect to the plan view of the space 18 patterns of Gr1 (first rotating lattice pattern) are created. When step S6 ends, the process proceeds to step S7.

  In step S7, it is checked whether or not the number of grid points of the first indoor unit arrangement grid Gr1 is within at least the number of the first rotation grid patterns of the 18 patterns within the plan view of the space. Delete the grid pattern. When step S7 ends, the process proceeds to step S11.

  In step S8, a second arrangement pattern in which the second center point on the horizontal line at the center of the vertical line with the first indoor unit arrangement grid Gr1 and the adjacent vertical line coincides with the center of gravity G1 of the plan view of the space (FIG. 4) and a third arrangement pattern (see FIG. 5) in which the center of the diagonal line (third center point) of a certain unit cell coincides with the center of gravity G1 of the space plan view. The first indoor unit arrangement grid Gr1 is created so that the horizontal lines thereof coincide with the east-west direction of the space plan view in both the second arrangement pattern and the third arrangement pattern. When step S8 ends, the process proceeds to step S9.

  In step S9, the first indoor unit arrangement grid Gr1 in the second arrangement pattern is rotated from 0 degrees to 175 degrees by 5 degrees from the second center point as a base point, and the first indoor unit arrangement grid with respect to the plan view of the space 36 patterns of Gr1 (second rotating lattice pattern) are created. Further, the first indoor unit arrangement grid Gr1 in the third arrangement pattern is rotated from 0 degrees to 85 degrees by 5 degrees from the second center point as a base point, so that the first indoor unit arrangement grid Gr1 ( 18 patterns of the third rotation lattice pattern) are created. That is, the total of the second rotating lattice pattern and the third rotating lattice pattern is 54 patterns. When step S9 ends, the process proceeds to step S10. FIG. 6 is an example of a second rotating grid pattern obtained by rotating the second arrangement pattern (FIG. 4) by 45 degrees.

  In step S10, the 36 second rotating lattice patterns and the 18 third rotating lattice patterns fit within at least the number of lattice points of the first indoor unit placement lattice Gr1 in the plan view of the space (inside the wall W1). Whether or not the number of patterns that have not been accommodated is deleted (the third arrangement pattern in FIG. 5 is deleted here). When step S10 ends, the process proceeds to step S11.

  In step S11, it is confirmed whether or not the distance (wall intersection distance) between the lattice point closest to the wall W1 and the wall W1 is smaller than one third of the first indoor unit interval a1. Specifically, whether the grid points of the first indoor unit placement grid Gr1 are within at least the number of indoor units in the virtual wall W2 that is one third of the first indoor unit interval a1 from the wall W1. It is confirmed (see FIG. 6). When the wall intersection distance is smaller than one third of the first indoor unit interval a1, the process proceeds to step S12, and when the wall intersection point distance is larger than one third of the first indoor unit interval a1, this grid diagram is created. The flowchart ends.

  In step S12, a second indoor unit arrangement grid Gr2 in which the size of the unit cell is reduced is created as the second indoor unit interval a2 having a length of 90% of the first indoor unit interval a1 (see FIG. 7). Here, FIG. 7 is obtained by performing step S12 on FIG. In this case, the second indoor unit arrangement grid Gr2 is reduced to a size of 90% from the first center unit (center of gravity G1) as the first indoor unit arrangement grid Gr1. When step S12 ends, the process returns to step S11.

(2) Arrangement method of indoor units When the first indoor unit arrangement grid Gr1 or the second indoor unit arrangement grid Gr2 is created as described above, the EHP indoor units and the GHP indoor units corresponding to the number of the indoor units are arranged in the first indoor unit. It arrange | positions at the lattice point of the machine arrangement | positioning grid Gr1 or the 2nd indoor unit arrangement | positioning grid Gr2. Here, the indoor unit is arranged so that the space is evenly air-conditioned so that there is no unevenness when the EHP indoor unit is operated alone or when the GHP indoor unit is operated alone. Therefore, the arrangement pattern of the EHP indoor unit and the GHP indoor unit is derived from the flowchart of FIG. Hereinafter, an arrangement pattern derivation flowchart of the EHP indoor unit and the GHP indoor unit will be described with reference to FIG.

  In step S21, the smaller number (small number) of the number of EHP indoor units and the number of GHP indoor units is selected. When the number of EHP indoor units is equal to the number of GHP indoor units, one of them is selected. When step S21 ends, the process proceeds to step S22.

  In step S22, the third indoor unit arrangement in which the following five intervals from the first interval A1 to the fifth interval A5 are the intervals between the small indoor units selected in step S21 (third indoor unit intervals a3, a4). Lattices Gr3 and Gr4 are created (see FIGS. 9 to 11). Here, the first interval A1 is the length of the diagonal of the unit cell, the second interval A2 is the length of two sides of the unit cell, and the third interval A3 is the rectangular diagonal of two unit cells. The fourth interval A4 is the length of the diagonal of the square of four unit cells, and the fifth interval A5 is the length of three sides of the unit cell (see FIG. 9). Here, for simplification of explanation, five intervals from the first interval A1 to the fifth interval A5 are used as the third indoor unit interval a3. However, the fifth interval A5 is not limited to this. The larger side may be set as one side of the unit cell. When step S22 ends, the process proceeds to step S23.

  In step S23, the five patterns of the third indoor unit arrangement grid Gr3 created in step S22 are overlapped with the first indoor unit arrangement grid Gr1 or the second indoor unit arrangement grid Gr2, and five patterns of the third indoor unit arrangement grid Gr3. , Gr4, the third indoor unit placement grids Gr3 and Gr4 having the pattern with the closest number of grid points (matching grid points) closest to the minority number are determined as the optimum third indoor unit placement grids. Here, it is determined which of the intervals from the first interval A1 to the fifth interval A5 is the optimum length of one side of the unit cell of the optimum third indoor unit arrangement lattice. When step S23 ends, the process proceeds to step S24.

  In step S24, an arrangement pattern of the optimum third indoor unit arrangement grid to the first indoor unit arrangement grid Gr1 or the second indoor unit arrangement grid Gr2 is further created. When step S24 ends, the process proceeds to step S25.

  In step S25, the number adjustment is performed when the number of matching grid points does not match the minority number. That is, if the number of coincident grid points is greater than a small number, do not place a small number of indoor units at any of the coincidence grid points. A small number of indoor units are arranged at the grid points of the first indoor unit arrangement grid Gr1 or the second indoor unit arrangement grid Gr2 to obtain a final arrangement pattern. When step S25 ends, the process proceeds to step S26.

  In step S26, the final arrangement pattern is displayed on the display. When step S26 ends, the arrangement pattern derivation flow ends.

In the air conditioner arrangement support system 1 according to the present embodiment, the unit air conditioning area and the first indoor unit interval a1 are calculated based on the floor area of the space and the number of indoor units, and the first indoor unit arrangement grid Gr1 is created. ing. Then, the first indoor unit placement grid Gr1 is positioned on a plan view of the space and rotated by 5 degrees with the center of gravity G1 as a reference point, thereby creating a plurality of rotary grid patterns. And the optimal 3rd indoor unit arrangement | positioning grid | lattice is created based on these rotation grid patterns, the number of EHP indoor units, and the number of GHP indoor units. In the optimum third indoor unit arrangement grid, the first interval from one EHP indoor unit to the remaining plurality of EHP indoor units is at least the first indoor unit interval a1 or the second indoor unit interval a2 or more. The shortest one interval is the first indoor unit interval a1 or the second indoor unit interval a2, and the second interval from one GHP indoor unit to the remaining plurality of GHP indoor units is at least the third indoor unit. A plurality of indoor units are arranged such that the unit intervals are a3 and a4 or more and the shortest second interval is the third indoor unit interval a3 and a4. In other words, the optimal third indoor unit arrangement grid is the position of the EHP indoor unit that can air-condition the space substantially when operating only the EHP indoor unit, and the GHP that can air-condition the space substantially even when operating only the GHP indoor unit. It is derived as the position of the indoor unit.

  As described above, the plurality of EHP indoor units are arranged at least the first indoor unit interval a1 or the second indoor unit interval a2 or more apart, and the radius of the first indoor unit interval a1 of the one EHP indoor unit is set. Since it can be arranged so that there is always one or more other EHP indoor units on the circumference or on the circumference of the second indoor unit interval a2, even when air conditioning of the EHP alone is performed, the space is minimized Air conditioning can be done evenly. Similarly, a plurality of GHP indoor units are spaced apart by at least the third indoor unit interval a3, a4, and each GHP indoor unit is always on the circumference of the radius third indoor unit interval a3, a4.
