AI Technical Summary
Existing building gutters are prone to freezing in winter, leading to poor drainage. Furthermore, electric heat tracing technology has high energy consumption, low safety, and high maintenance costs.
De-icing pipes are laid in the gutter. Heat pump units and heat exchangers are used to introduce warm water into the de-icing pipes. The graphene thermal conductive layer is used to de-ic the pipes. The de-icing pipes are emptied through a protective unit. Heat storage units are used to store heat during off-peak hours to reduce costs. Waste heat recovery units are used to reduce energy consumption.
It achieves efficient and safe gutter de-icing, extends service life, reduces operating and maintenance costs, and improves the system's economy and energy-saving effect.
