I. Cutting-Edge Spray Cooling Technology: The Principle of High-Pressure Micro-Mist Evaporative Cooling

This house‑spray cooling system, which has recently gained widespread attention, employs a purely physical evaporative cooling mechanism that absorbs heat, thereby eliminating the high energy consumption and substantial carbon emissions associated with conventional air conditioning. It is a key energy‑saving, low‑carbon technology promoted by the National Development and Reform Commission. Traditional air conditioners rely on refrigerant‑based cooling cycles, which are both energy‑intensive and unsuitable for outdoor, open‑space, large‑area applications. In contrast, Guangzhou Aogong’s high‑pressure mist cooling system uses specialized equipment to pressurize clean water to 7–12 MPa. Equipped with in‑house‑designed, precision stainless‑steel atomizing nozzles, it breaks the water into ultrafine droplets measuring 3–15 microns. Upon contact with hot air, these droplets instantly vaporize, rapidly absorbing ambient heat and delivering natural cooling without refrigerants or environmental pollution.

Field measurements demonstrate that within 10 minutes of startup, the system can reduce the temperature of building exterior walls by 5–8°C and lower ambient temperatures in the surrounding area by 3–8°C. For the same cooling coverage, its energy consumption is only one-tenth that of a conventional central air-conditioning system. The successful deployment at a demonstration residential complex in Shanxi fully validates its cost-effectiveness: the system’s water and electricity costs are exceptionally low, allowing it to be integrated into standard property‑management services without requiring additional fees from residents. In Guangzhou, Aogong can tailor the atomization parameters of its spray‑cooling systems to suit various site conditions, offering customized solutions for different environments.
