Air conditioner constant temperature dehumidification control method and system

Abstract

The invention provides a method and a system for controlling constant-temperature dehumidification of an air conditioner. The method comprises the following steps: detecting the outdoor environment temperature, the outdoor relative humidity and the indoor relative humidity and calculating the operating speed and duty ratio of an outdoor fan according to the outdoor environment temperature, the outdoor relative humidity and the indoor relative humidity; when the operating speed of the outdoor fan is less than the rotation speed of safe operation and the duty ratio is greater than the preset duty ratio, controlling the outdoor fan to operate according to the operating speed and the duty ratio; when the outdoor fan operates for preset time, detecting the indoor environment temperature and calculating the indoor temperature difference between the environment temperature and the preset indoor constant temperature; regulating the operating speed and duty ratio of the outdoor fan according to the temperature difference; if the temperature of the outdoor fan achieves a reliability protection point, performing reliability protection operation until the temperature is lower than the reliability protection point, releasing reliability protection and returning to a temperature different calculation step. According to the method, by virtue of detecting the indoor environment temperature, the operation of the outdoor fan is controlled so as to achieve a constant-temperature dehumidification effect, and the reliability protection ensures the reliability of the air conditioner.

Description

technical field [0001] The invention relates to the field of air conditioner dehumidification, in particular to an air conditioner constant temperature dehumidification control method and system. Background technique [0002] When the indoor humidity is high, the dehumidification function of the air conditioner can be used for dehumidification. However, in the traditional technology, the air conditioner easily causes the indoor ambient temperature to drop during the dehumidification process, and it is difficult to ensure that the indoor ambient temperature remains within a constant temperature range (such as ±1°C), which brings discomfort to the user. Contents of the invention [0003] Aiming at the problem that the indoor environment temperature will decrease during the dehumidification of the traditional air conditioner, the present invention provides an air conditioner constant temperature dehumidification control method and system with constant indoor environment tempe...
