Cabinet type air conditioner and control method thereof

Abstract

The invention relates to the technical field of air conditioners and particularly relates to a cabinet air conditioner and a control method thereof. The invention aims to solve the problem that an existing air conditioner has too cold or too hot air supply and large noise. For the above purpose, the cabinet type air conditioner of the present invention includes a cabinet, and a fan and a heat exchanger are set in the cabinet. The cabinet type air conditioner further includes an air mixing device, and the air mixing device includes a purification unit, an air guide unit and a jet unit. The purification unit includes a box body and a purification component. The box body is provided with a first air inlet and a first air outlet. The air guide unit includes a pipe body, the pipe body has a second air inlet and a second air outlet connected to the first air outlet, and an induced draft fan is arranged in the pipe body. The jet unit includes a cylinder, the cylinder has a third air inlet anda third air outlet connected to the second air inlet, and a jet channel is formed between the third air inlet and the third air outlet. The present invention can improve the phenomenon that the air supply of the air conditioner is too cold or too hot, and the operating noise of the air conditioner can be reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cabinet type air conditioner and a control method thereof. Background technique [0002] As air conditioners are widely used in thousands of households, users have higher and higher requirements for the performance of air conditioners. Take the cabinet air conditioner as an example. Usually under the same conditions, the performance of the cabinet air conditioner depends on the heat exchange efficiency, and the heat exchange efficiency is directly related to the air supply volume. The larger the air supply volume, the higher the heat exchange efficiency. high. In order to allow the indoor ambient temperature to rise or fall quickly, users usually adjust the wind speed of the air conditioner to a very high level, so that the air conditioner operates at a high speed and a large air volume. [0003] Although the above-mentioned control method can quickly lower or raise ...
