Vertical cabinet type air conditioner indoor unit

Abstract

The invention provides a vertical cabinet type air conditioner indoor unit. The vertical cabinet type air conditioner indoor unit comprises a shell, multiple radiation and convection type heat exchangers and an air supply device. An air inlet is formed in the lower portion of the shell, an air supply opening is formed in the upper portion of the shell, and the front portion of the shell comprisesa radiant panel. The radiation convection type heat exchangers are provided with radiation heat exchange parts and convection heat exchange parts, and are mounted in the shell, the radiation heat exchange parts are in cylinder shapes with openings in two ends and extending in the vertical direction, the radiation heat exchange parts are configured to absorb heat or cold from the inner wall faces thereof, and transmit the heat or cold to the radiant panel from the outer wall faces thereof, the convection heat exchange parts are arranged on the inner sides of the radiation heat exchange parts, are configured to generate heat or cold, transmit the heat or cold to air flowing through the inner sides of the radiation heat exchange parts and transmit the heat or cold to the inner wall faces of the radiation heat exchange parts, the radiation heat exchange parts are sequentially and coaxially mounted in the vertical direction, the air supply device is mounted in the shell, and is configured to at least prompt the air flow to enter the inner sides of the radiation heat exchange parts from the air inlet, and after heat exchange with the convection heat exchange parts, the air flow flows outof the air supply opening.

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
