Vertical cabinet type air conditioner indoor unit

Abstract

The invention provides a vertical cabinet type air conditioner indoor unit. A shell is included, an air inlet is formed in the lower part of the shell, and an air supply outlet is formed in the upperpart of the shell; a plurality of convection type heat exchangers are also included, are provided with airflow gathering parts and convection heat exchange parts, and are arranged in the shell; each airflow gathering part is in a barrel shape with openings in the two ends and extending in the vertical direction; each convection heat exchange part is arranged on the inner side of the correspondingairflow gathering part and is configured to generate heat or cold and transmit the heat or cold to air flowing through the inner side of the corresponding airflow gathering part; the plurality of airflow gathering parts are sequentially and coaxially arranged in the vertical direction; and an air supply device is further included, is arranged in the shell and is configured to at least promote theairflow to enter the inner sides of the air flow gathering parts from the air inlet, exchange heat with the convection type heat exchange parts and then flow out from the air supply outlet. The airflow organization of the convection type heat exchangers is optimized, the overflowing wind speed is increased, and the improvement of the air conditioner energy efficiency is promoted.

Description

technical field [0001] The invention relates to the field of refrigeration and heating, in particular to a vertical cabinet type air conditioner indoor unit. Background technique [0002] In recent years, with the improvement of the quality of life of the people, more and more attention has been paid to the thermal comfort of the indoor environment, and the energy consumption of buildings, especially the energy consumption of cooling and heating is also increasing. Comfortable cooling and heating devices are one of the research hotspots in the HVAC industry. In the existing air-conditioning indoor units, finned tube evaporators are usually used. The finned tube evaporators are large in size and high in cost. It is cumbersome, and there is still room for improvement in the heat transfer performance of the existing finned tube evaporator. In addition, the single evaporator air conditioner cannot reasonably distribute the cooling capacity, and can only eliminate sensible heat...

Problems solved by technology

In the existing air-conditioning indoor units, finned tube evaporators are usually used. The finned tube evaporators are large in size and high in cost. It is cumbersome, and the heat transfer performance of the existing finned tube evaporator still has room for improvement

In addition, the single evaporator air conditioner cannot reasonably distribute the cooling capacity, and can only eliminate sensible heat or latent heat alone, which has high energy consumption, and the indoor climate changes rapidly, causing poor comfort and easy drying
