Environmental value of wet curtain wall: How to achieve zero waste through water circulation system?

Wet curtain wall (water curtain wall/water curtain wall) is not only a beautiful landscape design, but also a sustainable environmentally friendly cooling solution. Through a scientific water circulation system, wet curtain wall can greatly reduce water waste and even achieve "near zero water consumption".

1. Environmental advantages of wet curtain wall

Efficient cooling, reducing air conditioning energy consumption

The principle of water evaporation and heat absorption can reduce the surrounding temperature by 3-8℃, reduce the use of air conditioning, and indirectly reduce carbon emissions.

Water resource recycling

The closed water circulation system can reuse water resources and only needs to supplement evaporation losses (daily water consumption <5%).

Compared with traditional fountains: the water consumption of wet curtain wall is only 1/10 of that of fountains.

Improve air quality

The water flow absorbs dust and PM2.5 in the air, especially suitable for industrial areas or busy traffic areas.

Low noise and eco-friendly

The sound of water flow can mask the ambient noise (about 40-50 decibels), which is quieter than mechanical fans.

No chemical coolant is required to avoid soil and groundwater pollution.

Advantages compared with traditional air conditioners

2. Design of water circulation system for wet curtain wall

Core components

Water reservoir: The bottom sump collects the falling water, and the capacity must meet the 1-hour circulation requirement.

Water pump: Variable frequency energy-saving water pump (such as IP68 waterproof grade) reduces power consumption.

Filter device:

Quartz sand filter: removes suspended particles.

UV sterilization lamp: inhibits algae growth (optional).

Water replenishment system:

Automatic water level controller, connected to rainwater collection device or reclaimed water reuse system.

Key technologies to achieve "zero waste"

Evaporation compensation: Automatic water replenishment through humidity sensor to avoid manual intervention.

Rainwater recycling: Roof rainwater is directed into the reservoir to replace tap water (suitable for areas with annual rainfall > 800mm).

Dry fog technology: High-pressure micro-fog nozzle reduces water droplet splashing and improves evaporation efficiency (saving 30% water).

3. Maintenance and optimization suggestions

Regular cleaning: Clean the filter every month to prevent algae from clogging the pipe.

Winter protection: drain the system or add antifreeze (in cold regions).

Energy matching: combine with solar water pumps to further reduce carbon footprint.
