All the other are not stated part and see first embodiment, no longer repeat.
To introduce several variations of indoor heat converter below.
Referring to Fig. 9, the angle of the angle α of indoor heat converter and long side, short side and vertical direction is all constant, remains under the situation of 54 degree and 27 degree, can reduce H by reducing ratio i: the ratio of D.H is the height that indoor heat converter and blower fan occupied jointly in the housing, and D is the maximum gauge of the worm gear of blower fan.Consequently: the length recruitment of short side is greater than the length decrease of long side, and actual heat exchange area increases to some extent.The M of the indoor heat converter among Fig. 9: N is 1.6; H: D is 1.9, and the structure of this indoor heat converter is than the compactness more among second embodiment.
Referring to Figure 10, the long side and the angle on the vertical direction of indoor heat converter are constant, remain 27 degree, and angle α is increased to 82 degree from 54 degree, reduce the ratio of M: N simultaneously, further to reduce the ratio of H: D.The M of the indoor heat converter among Figure 10: N is 1.22; H: D is 1.66, compact more than among Fig. 9 on its structure.
But, above-mentioned variation will bring another one newly to change, and be exactly that the short side of indoor heat converter and the angle of vertical direction become big, comparatively speaking, can make that the air heat exchange of passing through is insufficient, therefore when design, need this part heat exchange situation of re-computation.
Referring to Figure 11, with the long side and the increase of the angle on the vertical direction of indoor heat converter, angle α is increased to 95 degree, reduces the ratio of M: N simultaneously again, further to reduce the ratio of H: D.The M of indoor heat converter: N is 1.12 among Figure 11; H: D is 1.63.
Because the length summation of the long side of the indoor heat converter of this moment and short side, be M+N, the long side of the indoor heat converter in the former therewith where case is compared with the length summation of lacking side, tangible shortening is arranged, and promptly heat exchange area has tangible shortening, and therefore the mode that need take to increase comb is strengthened heat exchange, and the reinforcement heat exchange also must increase the thickness of heat exchanger, and then increase taking highly of inner space, so H: diminishing of D also has OK range to be limited
In sum, angle α as can be seen, the ratio i of the length of long side M and short side N, for the situation that influences of H: D, prompting should be noted that the measure that performance is improved in design.
