Air conditioner

Abstract

The present invention is to define a size of an indoor unit for air conditioner in consideration of an installation space of an air conditioner in houses in recent years, and to realize a high energy-saving performance (under APF standard) with dimensional constraint, by a shape and a structure of an indoor unit. The air conditioner includes a wall-hung type indoor unit, wherein the indoor unit including a case having a suction opening either at an upper surface or a front surface, or at the upper surface and the front surface, and a blowout opening at a lower surface, and a cross flow fan which sends air suctioned from the suction opening into the case to a blowout opening through an indoor heat exchanger, has a horizontal width of up to 800 mm, and a height of up to 295 mm, a diameter of the cross flow fan is not less than 100 mm but not more than 115 mm, and a number of stages in the indoor heat exchanger is not less than 16.

Description

technical field [0001] The present invention relates to an air conditioning device, in particular to an indoor unit. Background technique [0002] A conventional air conditioner has a structure in which the height of the indoor unit is 360 mm, the depth is 150 mm, the diameter of the cross-flow fan is 86 mm, and the number of stages of the indoor heat exchanger is 14 (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Publication No. 7-30926 (item 2, figure 1 ) [0004] At present, the energy saving of the air conditioner, which consumes the most electricity in the home, has become a mission of the whole society to suppress global warming. In particular, among the air-conditioning devices, split-type air-conditioning devices constitute the highest proportion of all air-conditioning devices. Compared with other types of classification, the specified value of the energy-saving law sets a high energy-saving specified value. In the type air...

AI Technical Summary

Problems solved by technology

[0008] As described above, the demand for larger capacity (higher capacity) of air-conditioning equipment has increased due to the increase in room size, and the above-mentioned energy-saving and high-efficiency improvements have also increased the size of the equipment. Another On the one hand, from the perspective of the above-mentioned residential environment, due to the limitation of the horizontal width, vertical width or both of the device size, the problem that the indoor unit of the air conditioning device cannot be installed has also increased.
