Ducted air conditioner indoor unit and control method thereof

Abstract

The invention discloses an air pipe type indoor air conditioner and a control method thereof. The air pipe type indoor air conditioner comprises a casing, an indoor heat exchanger and an indoor fan, wherein an air return inlet and an air outlet are formed in the casing; the indoor heat exchanger is arranged in the casing and positioned between the air return inlet and the air outlet; the indoor fan is arranged in the casing on one side of the indoor heat exchanger; the air outlet comprises a front air outlet formed in the front side wall of the casing and a lower air outlet formed in the lower side wall of the casing; the indoor air conditioner further comprises a switching mechanism for opening and closing the front air outlet and the lower air outlet. The air pipe type indoor air conditioner disclosed by the invention can adopt two air-out manners of the front air outlet and the lower air outlet, the manners of the front air outlet and the lower air outlet can be automatically selected according to the operational mode of the air conditioner, such as under the refrigeration mode and the dehumidification mode, the manner of the front air outlet is selected, and under the heating mode, the manner of the lower air outlet is selected, so that comfort of a refrigeration room and a heating room is considered, and the optimal comfort in the air regulation of the room is realized.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an indoor unit of an air duct type air conditioner and a control method thereof. Background technique [0002] The existing air duct type air conditioner indoor unit mainly includes a housing, an indoor heat exchanger and an indoor fan, wherein the housing is provided with an air return port and an air outlet, and the indoor heat exchanger and the indoor fan are both arranged in the housing. [0003] According to the different positions of the air outlets, the indoor units of ducted air conditioners can be divided into two types: front air outlet and bottom air outlet. The air outlet of the air duct type air conditioner indoor unit in the front air outlet mode is arranged on the front side wall of the housing. When the air conditioner is running, the wind blown by the indoor fan is directly sent into the room through the front air outlet. The air outlet of the indoor unit of the air duct ty...

Problems solved by technology

[0004] Due to the low density of hot air during heating, it is easy to float upwards, and the front air outlet method is not easy to blow the hot air to the lower part of the room, so the heating effect is poor; while during cooling, due to the high density of cold air, it is easy to sink, and the downward air outlet method is easy Blowing directly at people makes people feel cold

Therefore, the existing ducted air conditioner indoor unit considers the comfort of cooling, but ignores the comfort of heating, and considers the comfort of heating, but ignores the comfort of cooling, and cannot take into account the comfort of the room during cooling and heating.
