Figure 15 is the sectional view that represents the outlet for the air in electric part box is discharged.
In the above-described embodiment, four sides of outdoor heat converter 13 corresponding housing 5 configure (with reference to Fig. 6).Therefore, compared with three sides that should housing 5 being carried out to the occasion of disposed chamber's outer heat-exchanger 13, can expand the circulation area of air, improve the ability of heat exchange.In other words, by with four sides disposed chamber's outer heat-exchanger 13 accordingly of housing 5, even if dwindle the circulation area that the size of housing 5 also can keep air.Therefore, can under the prerequisite of ability that does not reduce outdoor heat converter 13, realize the miniaturization of housing 5.
On the contrary, once four sides disposed chamber's outer heat-exchanger 13 accordingly with housing 5, the peristome 36 forming between a side end 32a of outdoor heat converter 13 and another side end 35a is just less, and the configuration space ratio that electric part box 50 occupies this peristome 36 increases relatively.Therefore, at the remaining space that utilizes peristome 36, the equipment in housing 5 is maintained or during the operation such as replacing, may make workability worsen.
For this point, the off-premises station 2 of present embodiment is arranged in the top of electric part box 50 top of outdoor heat converter 13, and while seeing in the horizontal direction and wind guide component 30a overlapping, therefore, compared with the occasion below outdoor heat converter 13 upper ends by electric part box 50 configured in one piece, can dwindle electric part box 50 and occupy the configuration space of peristome 36.Therefore, can guarantee the space of the peristome 36 except the configuration space of electric part box 50 as far as possible, can utilize this peristome 36 equipment in housing 5 to be implemented to the operations such as maintenance.
In addition, the region in the horizontal direction outside of wind guide component 30a becomes the mobile dead sector of working in housing 5 to air hardly, therefore, even a part for electric part box 50 is configured in this region, also hardly can the mobile generation harmful effect in housing 5 to air, can not reduce heat exchanger effectiveness.
In addition, the top (Part I 51) of electric part box 50 is roughly trapezoidal or general triangular while being formed as overlooking, have the roughly rake 75B1 along wind guide component 30a, therefore, the dead sector that can more extensively effectively utilize the bight 5A of housing 5 configures electric part box 50.; past is rectangular when general electric part box is overlooked; therefore; even if electric part box will be configured in to the dead sector between bight 5A and the wind guide component 30a of housing 5; also can only utilize the scope that can hold rectangular electric spare parts kit; and the electric part box 50 of present embodiment has the rake consistent with the peripheral shape of wind guide component 30a (inclined wall) 75B1, therefore can utilize as best one can this dead sector, can guarantee fully the volume in electric part box 50.In addition, rake 75B1 is the plane of making while overlooking along the linearly extension of tangential direction of the periphery of wind guide component 30a, but also can make the arc-shaped surface extending along this peripheral shape.
In addition, electric part box 50 has the Part II 52 that area of section expands than this Part I 51 below Part I 51, therefore, even if do not expand the size of electric part box 50 above-below directions, also can enlarging volume.Therefore the peristome 36 that, can guarantee electric part box 50 belows has enough spaces.In addition, Part II 52 has expanded area of section with respect to Part I 51 at fore-and-aft direction (depth direction), the width (size relevant with the width of the 36A of open front portion) of left and right directions is identical with Part I 51 and Part II 53, therefore can also guarantee that the 36A of open front portion between electric part box 50 and outdoor heat converter 13 has enough width W.
As shown in Figures 3 and 4, electric part box 50 is configured in the bight 5A of the front left side of housing 5, and on the other hand, as shown in Figure 5,23, fan is near not configuring other bight of electric part box 50, the specifically forward right side of housing 5 and the configuration of the bight of right lateral side.Owing to electric part box 50 being configured in to the front left side of housing 5, therefore can form wider space.Again as shown in Figures 5 and 6, outdoor heat converter 13 is larger than left side in the ventilation area on the right side of housing 5, and therefore fan 23 is near the right side configuration of housing 5.Therefore, can suck more air from the right side of housing 5, can more effectively utilize outdoor heat converter 13 to carry out heat exchange.
