A kind of upper and lower air outlet air conditioner and anti-condensation control method thereof

Abstract

The invention belongs to the technical field of air conditioners, and discloses an air conditioner with up and down air supply and its anti-condensation control method. In the cooling or dehumidification mode of the air conditioner with up and down air outlet, the anti-condensation control is performed; the invention provides an air conditioner with up and down air supply, It has two upper and lower air outlets, which can realize various air supply modes such as downward air outlet, upper air outlet, and upper and lower air outlet according to user needs, and can satisfy the user's comfort experience while ensuring indoor temperature drop. According to different air supply modes, the present invention controls the operating frequency of the compressor and the opening of the electronic expansion valve in combination with parameters such as the set temperature, indoor ambient temperature, set fan speed, evaporator copper tube temperature, and air relative humidity, and then controls the evaporator. Surface copper tube temperature T 管温 , so that the current air dew point temperature T 露点 and evaporator tube temperature T 管温 The difference △T 防凝露 Keep it within a reasonable range to avoid condensation in the air conditioner while ensuring the rate of indoor temperature drop.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner with up and down air outlets and an anti-condensation control method thereof. Background technique [0002] At present, due to the continuous improvement of living standards, consumers have higher and higher requirements for the quality of air conditioners. The pure cooling and heating effect is no longer the main focus, and the comfort and good user experience are the hot spots that people pay more attention to. [0003] When the existing air conditioner operates in high-humidity weather, if the user sets the air conditioner to operate in a cooling state, condensation will easily form on the air conditioner due to the high air humidity. Usually, there will be a large amount of small water droplets around the air outlet of the air conditioner indoor unit, the sweeping blades and the back of the air deflector. During long-term operation, the...
