Automatic compensation method for supply air temperature of variable-air-volume air conditioner

Abstract

The invention provides an automatic compensation method for supply air temperature of a variable-air-volume air conditioner. The automatic compensation method comprises the following steps: acquiringthe data of a terminal device by utilizing an air conditioning terminal controller; building am LS-SVR temperature imbalance prediction model, wherein the air conditioning terminal controller adopts cascade PID control; calculating a required air volume value and an air valve opening degree value according to a temperature set value and a measured temperature value; meanwhile, predicting whether aroom temperature is imbalanced according to the air conditioning terminal controller and sending a prediction result to an air conditioning set controller; and automatically setting and adjusting a set temperature of an electric water valve of a coiled tube of an air conditioning set by using the air conditioning unit controller so as to control the opening degree of the electric water valve by using a PID algorithm and compensate the supply air temperature ahead of time. The automatic compensation method provided by the invention has the beneficial effects of predicting the trend of the roomtemperature ahead of time, adjusting the opening degree of the water valve in time by resetting a supply air temperature control valve, preventing possible system shock caused by adjustment after thetemperature is over-adjusted traditionally, realizing control of the supply air temperature as required, realizing rapid temperature control and running comfortably.

Description

technical field [0001] The invention relates to the technical field of automatic control of air conditioning systems, in particular to a method for automatically compensating the air supply temperature of a variable air volume air conditioner, which is mainly used to automatically adjust the opening of the coil electric water valve of the variable air volume air conditioner unit and prevent the temperature of the terminal room of the variable air volume air conditioner Unbalanced, to achieve the purpose of energy saving and comfortable operation. Background technique [0002] The variable air volume air conditioning system is a method of the full air air conditioning system, and it is a new technology developed with the energy saving requirements of the air conditioner. The variable air volume control method is based on the automatic adjustment of the variable air volume terminal device according to the room temperature and the set temperature, and automatically adjusts the ...

AI Technical Summary

Problems solved by technology

At present, the set value of the air supply temperature in the traditional variable air volume air conditioning system is constant. In actual use, due to factors such as changes in the end load, some end temperatures will deviate from the set temperature for a long time, and the temperature adjustment is too slow and the effect is not good. ideal
