The invention relates to a comprehensive pipe gallery jet fan position and angle optimization arrangement method based on a response surface method, and the method is characterized in that the method sequentially comprises the following steps: response surface experiment design, CFD sample simulation, response surface model construction, multi-objective optimization solution and optimal scheme verification. Wherein the response surface experiment design comprises variable definition, design method and sample size determination; the variables defined by the variables comprise the mounting position of the jet fan in the length direction of the comprehensive pipe gallery, the mounting angles of the jet fan on the upper and lower wall surfaces of the comprehensive pipe gallery, the mounting angles of the jet fan on the left and right wall surfaces of the comprehensive pipe gallery and the ventilation frequency; the design method is a Box-Behnken design method, and the Bhnken design method is a Bhnken. The sample size is four variables and three levels, and totally 27 samples are obtained. According to the method, optimization of airflow organization in the comprehensive pipe gallery can be achieved, the uniformity of temperature and humidity distribution is improved, the risk of local high temperature and high humidity is reduced, the ventilation efficiency is improved, and a ventilation strategy dynamically adjusted according to monitoring data or environment changes is achieved in an auxiliary mode.

This application relates to an automatic air conditioning adjustment method, apparatus, computer equipment, storage medium, and computer program product. The method includes: detecting the indoor carbon dioxide concentration; determining the target air volume required for the room within a preset future time period based on the carbon dioxide concentration result; determining the indoor dew point temperature based on the current indoor temperature; determining the target outlet air temperature based on the dew point temperature; determining the target air exchange rate to meet low ventilation conditions based on the temperature difference between the current indoor temperature and the outdoor temperature; determining the correspondence between the air conditioner's energy consumption, air outlet frequency, and air outlet speed based on the target air exchange rate and the target outlet air temperature; and determining the target air outlet frequency and target air outlet speed based on the correspondence. This method can provide a more suitable air environment while maintaining a relatively reasonable energy utilization ratio, achieving a balance between suitability and energy saving.
