Vertical cabinet type air-conditioner indoor unit

Abstract

The invention provides a vertical cabinet type air-conditioner indoor unit which comprises a shell, multiple convection type heat exchangers and an air supply device. The shell is provided with an airinlet and multiple air supply openings. The air inlet is formed in the lower portion of the shell. The multiple air supply openings are sequentially arranged in the vertical direction. The multiple convection type heat exchangers are arranged in the shell. At least one convection type heat exchanger is arranged on the lower side of a position where each air supply opening is located with a same height. Each convection type heat exchanger is provided with an airflow gathering portion and a convection heat exchange portion. Each airflow gathering portion is in a cylinder shape with openings formed in two ends, wherein the cylinder shape extends in the vertical direction. Each convection heat exchange portion is arranged on the inner side of the corresponding airflow gathering portion. The multiple airflow gathering portions are sequentially arranged in the vertical direction. The multiple airflow gathering portions are arranged coaxially. The air supply device is arranged in the shell,and is arranged to urge airflow to enter the shell from the air inlet, and flow out of the shell from one or more air supply openings. The airflow flowing out of each air supply opening exchanges heatwith the corresponding convection heat exchange portion at the lower side of the height position where the air supply openings are located.

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 people’s quality of life, 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, has also increased. Therefore, it is highly energy-efficient and has good thermal Comfortable heating and cooling devices are one of the research hotspots in the HVAC industry. In the existing indoor unit of air conditioner, finned tube evaporator is usually used. The finned tube evaporator has a large volume and a high cost. The convection heat transfer coefficient of the air flow drawn by the fan is small, the air flow organization is poor, and the production process is relatively small It is complicated, and the heat exchange performance of t...

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
