The Saving System is an energy-saving system based on rainwater circulation: it purifies and stores collected rainwater, then reuses it for cooling. Debris and contaminants are filtered from rainwater collected on roofs and other surfaces, and only clean rainwater is selected and stored so it can be reused reliably.

The system senses its operating environment from temperature and humidity sensor data and sprays stored rainwater as fine droplets onto outdoor AC units, quickly lowering their surface temperature and improving cooling efficiency. With non-powered automatic operation and efficient spray volume control, it reduces the energy burden and can be used effectively for the continuous operation and maintenance of cooling equipment.
