Embodiment Construction
[0092] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0093] For the control flow chart of the first embodiment of the air-conditioning intelligent control method based on personnel information in the air-conditioning area of the present invention figure 1 , including the following steps:
[0094] Include the following steps:
[0095] Step S1, calculate the VAVbox according to the number of personnel in the air-conditioning area controlled by the terminal device VAVbox of the variable air volume air conditioning system connected to the air handling unit AHU i Control the minimum fresh air volume Moamin in the air-conditioned area i , according to Moamin i Calculate the total amount of fresh air Moa of the air handling unit AHU; where, i is the sequence number of the air-conditioning area controlled by VAVbox, Moa=∑Moamin i ;
[0096] Step S2, according to the VAVbox i Control the current return air...

The invention provides an intelligent air-conditioner control method based on person information in an air-conditioning area. The intelligent air-conditioner control method comprises the following steps: S1, according to the minimum fresh air volume Moamini of VAVboxi connected with an AHU, calculating the total fresh air volume Moa of the AHU according to Moamini, wherein Moa=sigma Moamini; S2, according to Trai and Trseti, implementing dual PID control so as to obtain Dseti; S3, calculating the total air supply volume Msa of the HAU, and according to Dseti, performing static pressure PID control so as to obtain the total air supply volume Msa; S4, according to the ratio of Moa to Msa, adjusting the opening of a fresh air valve Voa. As dual PID control is performed according to Trai and Trset so as to obtain the opening Dseti of a tail end air valve, the comfort degree of the air-conditioning area under the VAVboxi control is increased; meanwhile the opening degree Voa of the fresh air valve is adjusted according to the ratio of Moa to Msa, the accuracy of fresh air control of the air-conditioning area under the VAVboxi control is improved.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to an intelligent air conditioning control method and system based on personnel information in an air conditioning area. Background technique [0002] Today, with the rapid development of science and technology, video surveillance systems are increasingly popular and widely used in public buildings and residential buildings. Video surveillance systems can effectively monitor and count the number of people in air-conditioned areas. A variable air volume (VAV) air conditioning system is a full-air air conditioning system that satisfies changes in indoor load by changing the air volume at the end. The system has good energy saving and comfort, and meets users' good requirements for indoor air quality. The general control method of the variable air volume air conditioning system is: when the air conditioning load changes, the air supply volume of the air conditioner is changed...
