Method and device for controlling temperature and humidity of air conditioner

Abstract

The invention relates to a method and a device for controlling the temperature and humidity of an air conditioner and aims to solve the technical problems of drastic fluctuation of the air outlet temperature, excessive dehumidification and insufficient dehumidification of a common air conditioner in the refrigeration and dehumidification process. The method comprises the steps of collecting the indoor temperature, the outdoor temperature and the indoor coil temperature in the dehumidification mode of the air conditioner; conducting judgment to enter a defined temperature area according to the indoor temperature; calculating initial parameters such as compressor frequency, expansion valve opening, indoor fan rotating speed, outdoor fan rotating speed and swing blade angle according to the indoor temperature, the outdoor temperature and the indoor and outdoor temperature difference after entering the corresponding temperature area; after operating for a period of time, adjusting and correcting the compressor frequency, the expansion valve opening degree, the indoor fan rotating speed, the outdoor fan rotating speed and the swing blade angle as well as starting and stopping of an auxiliary heating device according to the difference value between the real-time indoor temperature and the outdoor temperature of the corresponding temperature area, the difference value between the indoor temperature and the corresponding preset temperature and the change rate change of the temperature of the indoor coil within a certain period of time. The method and the device are mainly used for dehumidification of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of dehumidification of household air conditioners, in particular to a control method and device for comfortable dehumidification of household air conditioners. Background technique [0002] With the improvement of people's living standards, users have higher and higher requirements for the comfort and health of air conditioners. Traditional air conditioners often cannot take into account both temperature and humidity during cooling operation. In the appropriate temperature and humidity range, it will breed A large number of bacteria; and the bacteria will enter the room along with the air supply of the indoor unit, which will have a certain impact on the user's health and comfort experience. [0003] At the same time, in the actual cooling and dehumidification operation of ordinary household air conditioners, when the room temperature is much higher than the set temperature, the compressor operates at high f...
