AI Technical Summary
Existing external wall insulation devices consume high levels of air conditioning energy in southern regions during the summer, and the construction quality is difficult to guarantee, posing safety hazards.
The insulation layer is placed on the indoor side of the exterior wall, and the external sunshade is placed on the outdoor side. The sunshade is used to block solar radiation heat and reduce the amount of heat entering in summer. At the same time, holes are drilled in the sunshade to improve heat dissipation efficiency.
It reduced air conditioning energy consumption in southern regions during the summer, improved construction quality, and avoided the safety hazard of insulation layer detachment.
