Embodiment Construction

[0038] figure 1 It is a schematic structural diagram of a vertical cabinet air conditioner indoor unit according to an embodiment of the present invention. Such as figure 1 shown and refer to Figure 2 to Figure 8 , the embodiment of the present invention provides a vertical cabinet air conditioner indoor unit, which includes a casing 100 , a convection heat exchanger 200 and a fan 300 . The lower part of the casing 100 is provided with an air inlet 110 , and the upper part is provided with an air outlet 120 . The convective heat exchanger 200 may include an airflow gathering part 20 and a convective heat exchange part 30 . The airflow converging portion 20 is in the shape of a cylinder with both ends open and extending in the vertical direction. Further, the outer contour of the cross section of the airflow converging portion 20 is circular, semicircular, square or fan-shaped. The convective heat exchange part 30 is disposed inside the air gathering part 20 and is config...

Abstract

The invention relates to a cabinet type air conditioner indoor unit. The cabinet type air conditioner indoor unit comprises a shell, a convection type heat exchanger and a fan; an air inlet is formedin the lower part of the shell; an air feeding port is formed in the upper part of the shell; the convection type heat exchanger is provided with an air flow convergence part and a convection heat exchange part, and is arranged in the shell; the air flow convergence part is a cylinder which has openings in two ends and extends in a vertical direction; the convection heat exchange part is arrangedon the inner side of the air flow convergence part, and is configured to generate heat or cold and transfer the heat or cold to the air which flows through the inner side of the air flow convergence part; and the fan is configured to at least promote an air flow to enter from an air inlet to the inner side of the air flow convergence part and to flow out from the air feeding port after exchangingheat with the convection heat exchange part. Air flow distribution of the convection type heat exchanger is optimized; the overflowing air velocity is improved; and the improvement of the energy efficiency of an air conditioner 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. Contents of the invention [0003] The object of the present invention is to overcome at least one defect of the existing air conditione...
