[0002] Building HVAC is an important category of building equipment, covering three core aspects: heating, ventilation and air conditioning. Inside the building, heating supplies heat to the room by consuming energy, ventilation improves indoor air quality by air exchange, and air conditioning aims to create suitable environmental conditions to meet people's production, life and scientific experiment needs. In these working processes, building HVAC pipes play a vital role. They are responsible for transporting hot air, fresh air or elements necessary to regulate air quality. In order to effectively operate the building HVAC system, each pipe needs to be connected accurately, which requires reliable building HVAC pipe connection devices to ensure that the system operates safely and efficiently and meets the needs of the building's internal environment.
