<p>As the exhibition space of culture and art, museums often face the challenge of controlling environmental heat energy. Traditional air conditioning systems cannot effectively meet the dual needs of energy conservation and comfort, especially in the case of the protection of special exhibits and changes in the density of people. This study aims to explore the control method of environmental heat energy based on infrared sensing technology and behavior monitoring, and enhance the audience experience through interactive visual communication design, so as to realize the intelligent management of the environment in the museum. In this paper, infrared sensors are used to monitor the temperature, humidity and personnel flow data in the museum, and real-time behavior monitoring system is combined to establish an environmental heat energy regulation model. Through data analysis, a dynamically adjusted HVAC (heating, ventilation and air conditioning) system is designed to achieve precise control of thermal energy. At the same time, interactive visual communication design is applied to provide real-time feedback to the audience and improve their perception of environmental changes. After implementation, temperature fluctuations within the museum were significantly reduced and energy consumption was reduced. The satisfaction of visitors, as assessed by questionnaires, showed a significant improvement, especially in terms of conservation and comfort of exhibits. Therefore, the thermal energy control system based on infrared sensing and behavior monitoring not only effectively improves the energy efficiency of the museum environment, but also enhances the immersion experience of the audience.</p>
