Embodiment
The present invention will be further described below：
1）Determine plane vertically arranged horizontal spacing ds and fore-and-aft distance d0
As shown in figure 1, according to two air-conditioner outdoor units in the vertically arranged actual installation condition of groove inner plane, determining that plane is hung down
The horizontal spacing and longitudinal pitch directly arranged, value is 50mm, 150mm, 250mm successively for the lateral separations of two outdoor units,
350mm, 450mm, 550mm, 650mm, 750mm, 850mm.Value is 100mm to the fore-and-aft distance of two outdoor units successively,
200mm, 300mm, 400mm, 500mm, 600mm, 700mm.
2）Sample data is obtained by experimental method
The vertically arranged horizontal spacing of plane for two outdoor units that analysis is obtained deploys experiment successively with longitudinal pitch more than,
Distance controlling of the outdoor unit away from wall is in 150mm in experimentation, and the distance controlling away from blinds is in 250mm, groove height
1200mm, blocks blinds and uses aluminum alloy beancurd leaf, blinds spacing is 100mm, and width of blade is 50mm, and the control of blinds aperture exists
10°.Indoor and outdoor side temperature is respectively set to 35 DEG C, 25 DEG C, and air-conditioning design temperature is 18 DEG C.Hung down by the plane of platform outdoor unit
The horizontal spacing directly arranged and the change of longitudinal pitch are tested, and obtain experiment sample data.

0.61 DEG C, 0.68 DEG C, 0.55 DEG C, 2.1 DEG C, 0.49 DEG C, 0.45 DEG C, distance from 550mm increase to 650mm when, at a temperature of the range of decrease
Degree is maximum, is 2.1 DEG C.As seen from Figure 3, distance from 250mm increase to 350mm when, the EER increasing degrees of outdoor unit 1 are most
Greatly, it is 0.19.Distance from 550mm increase to 650mm when, the EER increasing degrees of outdoor unit 2 are maximum, are 0.53.Consider face
Product cost and two outdoor unit return air temperatures, the variation tendencies of trapped energy theory, determine two outdoor units with plane vertical mode cloth
When putting, optimal lateral spacing is 650mm.As seen from Figure 4, with the increase of spacing, the return air of outdoor unit 1 and outdoor unit 2
There is first reducing the trend increased afterwards in temperature, and when spacing is 300mm, return air temperature is minimum, respectively 46.41 DEG C, 42.71 DEG C,
2.6 DEG C, 1.15 DEG C are reduced during than d0=100mm respectively；Reduce 7.52 DEG C during than d0=700mm respectively, 6.23 DEG C, and room
The return air temperature of outer machine 1 is consistently higher than the return air temperature of outdoor unit 2.As seen from Figure 5, the efficiency of outdoor unit 1 and outdoor unit 2
There is the trend of first increases and then decreases with the increase of longitudinal pitch than EER, maximum is reached when spacing is 300mm, be respectively
2.08th, 1.63,12.68%, 8.49% is increased during than d0=100mm respectively；Increase 48.39% during than d0=700mm respectively,
131.06%.Therefore, make outdoor unit ambient thermal conditions good, be conducive to air-conditioner set to run, make air conditioner that there is higher energy efficiency ratio
Optimal longitudinal pitch be 300mm.In summary, optimal lateral mounting distance ds is 650mm, optimal mounting distance d0For
300mm。
