Air conditioner temperature control method and device based on homogeneous control theory

Abstract

The invention discloses an air conditioner temperature control method based on the homogeneous control theory. The method comprises the steps that when a temperature controller determines that a temperature difference exists, whether the temperature difference is greater than a preset first temperature difference threshold value or not is detected in real time; when the temperature difference is greater than the first temperature difference threshold value, the temperature controller determines the temperature difference which is greater than the first temperature difference threshold value as an initial target temperature difference; and when each preset control cycle of the temperature controller is started, the temperature controller conducts temperature control according to a control value corresponding to an initial point of the preset control cycle in the preset control cycle until the target temperature difference corresponding to the control value of the initial point of the preset control cycle is smaller than a second temperature difference threshold value, and the temperature control in the preset control cycle is stopped. The invention further discloses an air conditioner temperature control device based on the homogeneous control theory. The air conditioner temperature control method and device based on the homogeneous control theory are capable of reducing the energy consumption, increasing the energy utilization rate and reducing the cost, and are more environmentally friendly and more efficient.

Description

technical field [0001] The invention relates to the field of air conditioner temperature control, in particular to an air conditioner temperature control method and device based on homogeneous control theory. Background technique [0002] The air-conditioning temperature controller is an important part of the subway operation system, and its energy consumption accounts for about 40%-60% of the total energy consumption of the subway building. The main reason for this is that when there is a temperature difference between the measured value of the temperature and the preset target temperature value, it is necessary to call the air-conditioning temperature controller to control the temperature to eliminate the temperature difference. However, the current air-conditioning temperature control system uses the traditional The control theory controls the temperature, but the traditional control theory often leads to too long stabilization time, that is, the time required to reach th...
