AI Technical Summary

Technical Problem

The fin tube evaporators of existing air-conditioning indoor units are large in size and high in cost, and there is room for improvement in heat exchange performance. The single evaporator cannot reasonably allocate the cooling capacity, resulting in high energy consumption and poor comfort.

Method used

The vertical cabinet air conditioning indoor unit is designed including a shell, radiating plate and radiating convection heat exchanger. Through the combination of radiating convection heat exchanger and radiating plate, the airflow organization is optimized, the heat exchange coefficient is improved, and more uniform airflow distribution is achieved through multiple air supply ports.

Benefits of technology

It improves heat exchange performance, reduces production costs and space occupancy, achieves more efficient air conditioning energy efficiency, improves cooling utilization and indoor comfort, and avoids waste of cooling capacity through independent control of temperature and humidity.

Abstract

The present invention provides a cabinet-type air conditioner indoor unit. The indoor unit comprises: a shell, an air inlet and a plurality of air supply ports are arranged on the shell, the air inlet is arranged at the lower part of the shell; and the front part of the shell comprises a plurality of radiation plates; the plurality of air supply ports and the plurality of radiation plates are arranged alternately in the vertical direction, and an air supply port is arranged on the upper side of the uppermost radiation plate; a plurality of radiation convection heat exchangers, and at least one radiation convection heat exchanger is arranged on the rear side of each radiation plate; each radiation convection heat exchanger has a radiation heat exchange part and a convection heat exchange part, and is arranged in the shell; and the radiation heat exchange part is in the shape of a cylinder with openings at both ends and extending in the vertical direction; the convection heat exchange part is arranged on the inner side of the radiation heat exchange part; and an air supply device is arranged in the shell, configured to promote airflow to enter the shell from the air inlet and flow out of the shell from one or more air supply ports; and the airflow flowing out of each air supply port exchanges heat with each convection heat exchange part on the lower side of the height position where the air supply port is located.
