Abstract

The invention provides an indoor unit of a vertical air conditioner. The indoor unit comprises a machine shell, a heat exchanger, a first cross flow fan and a second cross flow fan; a plurality of vertically arranged air outlets are formed in a front panel of the machine shell, and an air inlet is formed in the rear side of the machine shell; the heat exchanger is arranged in the machine shell; the first cross flow fan and the second cross flow fan are vertically arranged and are collinearly arranged in the machine shell, the axis of each of the first cross flow fan and the second cross flow fan vertically extends in the machine shell, each of the first cross flow fan and the second cross flow fan is configured to promote air to enter the machine shell through the air inlet and be blown out through the corresponding air outlet after being subjected to heat exchange with the heat exchanger; and the rated air flow of the first cross flow fan is larger than that of the second cross flow fan, and the total open area of all the air outlets corresponding to the first cross flow fan is larger than that of all the air outlets corresponding to the second cross flow fan. The indoor unit of the vertical air conditioner, provided by the invention, is relatively low in fan air pressure loss, capable of saving more energy in operation and variable in air supply modes, so that the experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a vertical air conditioner indoor unit. Background technique [0002] At present, traditional vertical air conditioner indoor units mostly use a centrifugal fan as a power source to drive air flow. The centrifugal fan and the heat exchanger are arranged in the casing of the indoor unit along the vertical direction, the air inlet is arranged at the lower part of the casing, and is opposite to the centrifugal fan, and the air outlet is arranged at the upper front side of the casing, and is connected with the heat exchange device. relatively. The air enters the casing through the air inlet at the lower part, flows through the air channel of the centrifugal fan and the heat exchanger in turn, and then is sent out from the air outlet at the upper part. It can be seen that the distance of the airflow from the air inlet to the air outlet is longer, the wind pressure loss is m...
