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, a plurality of radiation convection type heat exchanger and an air supply device; the shell is provided with an air inlet and a plurality of air supply outlets, and the air inlet is formed in the lower portion of the shell; the front part of the shellcomprises a plurality of radiation plates, the plurality of air supply outlets and the plurality of radiation plates are alternately arranged in sequence in the vertical direction, and one air supplyoutlet is formed in the upper side of the uppermost radiation plate; at least one radiation convection type heat exchanger is arranged on the rear side of each radiation plate, each radiation convection type heat exchanger is provided with a radiation heat exchange part and a convection heat exchange part, and is arranged in the shell, and each radiation heat exchange part is in a barrel shape with the two ends open and extending in the vertical direction; and the convection heat exchange parts are arranged on the inner sides of the radiation heat exchange parts, the air supply device is arranged in the shell and is configured to promote airflow to enter the shell from the air inlet and flow out of the shell from the one or more air supply outlets, and airflow flowing out of each air supply outlet exchanges heat with the corresponding convection heat exchange part on the lower side of the height position where the air supply outlet is 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 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
