Upper and lower exhaust wall-mounted air conditioning indoor unit

Abstract

The invention relates to the technical field of air conditioners, in particular to an upper and lower exhaust wall-mounted air conditioning indoor unit. The upper and lower exhaust wall-mounted air conditioning indoor unit comprises a shell, an upper crossflow wind wheel, a lower crossflow wind wheel, an upper evaporator, a lower evaporator, a first wind way and a second wind way, wherein a wind inlet is formed on a side surface end plate of the shell; indoor return wind enters two side cavities from side surface end plates at two sides, and enters a wind inlet cavity formed among the upper evaporator, the lower evaporator and a front panel of the shell; then, an air current is divided into two ways for heat exchange by the upper evaporator and the lower evaporator, and is blown out from the first wind way and the second wind way after being guided by the upper crossflow wind wheel and the lower crossflow wind wheel; the wind blown out from the first wind way reaches an indoor ceiling to form an absorption effect, and sinks after being blown for a longer distance; and as the wind inlet is arranged on the side surface end plate, the indoor air current structure is formed to surrounding wind to intensify the indoor air disturbance, the indoor temperature field distribution is more uniform, and the temperature is more comfortable.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a wall-mounted air conditioner indoor unit with up and down air outlets. Background technique [0002] At present, the air outlets of the existing wall-mounted air conditioner indoor units are basically arranged at the lower end, and the upper and lower ranges of the air are guided by the horizontal air guide strips. However, due to the high density of the cold air blown out during cooling, the air flow tends to sink. If the wind deflector is used to guide, the cold wind may still directly blow to the human body, causing discomfort to the human body. At the same time, when the air guide strip is turned upward, the air outlet will be reduced, which will greatly reduce the air volume. Thus affecting the cooling performance. [0003] In order to improve the air outlet effect of the indoor unit, air conditioners with upper and lower air outlets have also been developed in t...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a wall-mounted air conditioner indoor unit with up and down air outlets, which can improve the air outlet effect of the indoor unit, and on the one hand solve the indoor temperature field caused by the "short circuit" of the air outlet existing in the existing upper and lower air outlet air conditioner indoor units The problem of uneven distribution, on the other hand, solves the problem of insufficient air volume and poor indoor heat exchange effect caused by the non-independent air ducts of the existing upper and lower air-conditioning indoor units
