Air-conditioner and drainage control method thereof

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air-conditioner and a drainage control method thereof. The air-conditioner and the drainage control method thereof aim to solve the problem that a drainage method of an existing air-conditioner is not efficient enough. The drainage control method comprises the steps that coil pipe temperature and current dew point temperature of an indoor unit are obtained; and a drainage pump is controlled selectively according to the coil pipe temperature and the current dew point temperature of the indoor unit.According to the drainage control method, the coil pipe temperature and the current dew point temperature of the indoor unit are taken as basic parameters to judge whether the indoor unit may generatecondensate water or not, so that the air-conditioner can control the drainage pump to operate selectively according to the generating conditions of condensate water, and thus operating states of thedrainage pump can be adjusted correspondingly according to different requirements, and then the operating efficiency of the drainage pump is guaranteed effectively.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner and a drainage control method thereof. Background technique [0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment. In order to maintain a comfortable ambient temperature, air conditioners have become an essential device in people's lives. When the air conditioner is in cooling operation, the heat exchanger of the indoor unit is in a low temperature state; therefore, the water vapor in the air is easily liquefied when it contacts the heat exchanger of the indoor unit, resulting in a large amount of condensed water. In order to effectively avoid many problems caused by the leakage of condensed water, the indoor unit of the existing air conditioner is usually equipped with a water receiving tray, and a water pump is also arranged in the wat...
