Indoor unit of air conditioner and dehumidifying method and dehumidifying device thereof

Abstract

The invention provides an indoor unit of an air conditioner and a dehumidifying method and a dehumidifying device thereof, relates to the technical field of air conditioners, and is used for solving the problem of weak dehumidifying capacity of the indoor unit of a traditional air conditioner under the working condition of part load. The dehumidifying method comprises the steps of: obtaining an evaporation temperature of an evaporator measured by a first temperature sensor and an indoor environmental temperature measured by a second temperature sensor; determining a first target evaporation temperature according to the indoor environmental environment and a first preset rule, wherein the first preset rule includes a corresponding relation between the indoor environmental temperature and a third target evaporation temperature, and the first target evaporation temperature is obtained according to the third target evaporation temperature and a first preset threshold; and adjusting the openness of at least one throttling device in an opening state if the evaporation temperature of the evaporator is higher than or equal to the first target evaporation temperature. The dehumidifying method can be applied to dehumidifying control of the indoor unit of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit, a dehumidification method, and a dehumidification device. Background technique [0002] In hot summer, when people are placed in two rooms with the same room temperature but different indoor ambient humidity, they will obviously feel that the temperature in the room with high humidity is higher than that in the room with low humidity. This is because when the humidity is high, the sweat produced by the human body is not easy to evaporate, so you will feel stuffy; and when the humidity is low, the sweat produced by the human body is easier to evaporate, so you will feel cooler. This phenomenon is extremely obvious in areas with high temperature, high humidity, or perennial rain. Therefore, in these areas, whether the air conditioner has a dehumidification function is particularly important. [0003] The dehumidification of existing air con...
