Split air-conditioner indoor unit

Abstract

The invention discloses a split air-conditioner indoor unit, which comprises an upper shell arranged on the body. A heat exchanger, a cross flow wind wheel and an air duct for accommodating the heat exchanger and the cross flow wind wheel are arranged in the upper shell; the upper shell is provided with an air inlet and an air outlet which are communicated with the air duct, the air duct comprises a left air duct and a right air duct, the front of the upper shell is provided with a front panel, and a middle partition plate is arranged in the upper shell; the left air duct is encircled by the upper shell, the front panel, the middle partition plate and a left volute of a left cross flow wind wheel together; a left heat exchanger, the left cross flow wind wheel and a left volute tongue of the left cross flow wind wheel are arranged in the left air duct; the right air duct is encircled by the upper shell, the front panel, the middle partition plate and a right volute of a right cross flow wind wheel together; and a right heat exchanger, the right cross flow wind wheel and a right volute tongue of the right cross flow wind wheel are arranged in the right air duct. The split air-conditioner indoor unit has the characteristics of simple and reasonable structure, small integral volume, high energy efficiency ratio, flexible installation mode and wide application range.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an indoor unit of a split type air conditioner. Background technique [0002] Traditional floor-standing air-conditioning indoor units, such as attached figure 1 - attached figure 2 As shown, it adopts a single centrifugal wind wheel structure. In order to increase the heat exchange area, it is often realized by increasing the thickness of the fuselage, increasing the width or height of the fuselage. When the size of the fuselage is increased, the aesthetics of the product will be reduced, and the wind speed of different parts of the heat exchanger will vary greatly, which will not give full play to the heat exchange performance of the heat exchanger. When the air volume is increased by increasing the speed of the wind rotor, problems such as increased noise are caused. [0003] In addition, other similar cabinet indoor units using double through-flow wind wheels, such as Chinese Patent ...

AI Technical Summary

Problems solved by technology

The heat exchangers are all in the form of flat plates or V-shaped, and all of them need to enter the air from the back or the front of the cabinet, resulting in low utilization efficiency of the heat exchanger, and the air duct structure formed with the cross-flow wind wheel cannot be optimal. And due to the installation form of the cabinet machine, the air intake from the back is too low, or the cabinet machine cannot enter the air at all when it is installed against the wall, which greatly affects the heat exchange capacity of the heat exchanger and lacks practical value

[0005] The traditional split wall-mounted air-conditioning indoor unit generally has a suspension height of more than 1.8 meters, and some are even higher. The air blowing downward or obliquely is used to increase or decrease the temperature in the space. There are differences between the heights of the range of human activities, and the descending airflow cannot be well concentrated on the height area of ​​human activities for temperature adjustment, resulting in waste of cooling or heat
