AI Technical Summary
Existing curtain wall buildings' drainage pipes generate noise when dripping intermittently or continuously, affecting the user experience. In cold environments, they are prone to freezing, which can damage the equipment and reduce the practicality of the drainage system.
A concealed drainage pipe structure including a water collection tank and a gravity valve was designed. The water collection tank collects accumulated water and automatically discharges it through the gravity valve when a certain amount is reached. Combined with components such as a filter screen, insulation layer, heating element and temperature sensor, the stable operation of the drainage system is ensured.
It effectively reduces the noise from frequent dripping of the drain pipe, improves the user experience, maintains the stability of the drainage function in cold environments, and reduces maintenance costs and the risk of equipment damage.
