Problems solved by technology

[0003] 1. The purpose of the present invention is to provide an air-conditioning humidification and fresh air indoor unit, which can not only introduce outdoor air, but also solve the problem of dirty indoor air caused by the air outlet of the existing air-conditioning indoor unit, without increasing the production cost. While the oxygen content of the indoor air is constantly declining, it can also humidify the indoor air, solve the problem of drying the indoor air due to the decrease in humidity, and recover the wasted cooling capacity when the water droplets condensed on the heat exchanger are discharged outside. At the same time, it can also increase the temperature and air volume of the air outlet of the indoor unit, and improve the comfort of the air outlet of the indoor unit

Abstract

The invention discloses a humidifying and fresh air exchange indoor unit of an air conditioner. The humidifying and fresh air exchange indoor unit comprises a cross-flow impeller air outlet duct and a cross-flow impeller air outlet duct wall. The humidifying and fresh air exchange indoor unit is characterized in that an air induction opening is formed in the cross-flow impeller air outlet duct wall; the clockwise included angle between the projection line, in a projection plane which is perpendicular to the axis of a cross-flow impeller of the indoor unit and makes an air outlet of the indoor unit be located on the lower left side, of the air induction opening and an air outlet duct wall tangent positive direction section making the point intersecting with the air outlet duct wall as an upper tangent point is larger than or equal to 15 degrees and smaller than or equal to 180 degrees; a water discharge pipe of the indoor unit is connected with an air induction pipe, and the other port of the air induction pipe is connected with the air induction opening formed in the cross-flow impeller air outlet duct wall in a penetrating mode. The humidifying and fresh air exchange indoor unit has the advantages that outdoor air is introduced, humidified and exchanged; the refrigerating capacity is recycled, so that energy is saved; the air outlet temperature and the air volume of the indoor unit are increased.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and only relates to a split air conditioner humidifying and fresh air indoor unit. Background technique [0002] The existing split air conditioner includes an outdoor unit and an indoor unit, and the indoor unit usually adopts a cross-flow fan to enter and exit the air. When the indoor unit is working, the indoor air is sucked into the indoor unit under the action of the cross-flow fan, and after heat exchange with the heat exchanger, it becomes heat-exchanged air, and returns to the room through the air outlet duct of the indoor unit. the goal of. There are three problems: 1. In the cooling mode of the indoor unit, when the indoor air becomes cold and hot exchanged air after heat exchange with the heat exchanger, water droplets will condense on the heat exchanger, and the water droplets will drip into the water tray and flow along The drain pipe of the air conditioner flows out of th...
