precooloing-setupPre-Cooling of HVAC & Refrigeration Units through Evaporative Fogging

Why PreCooling is an especially important technology

•    Refrigeration and air conditioning account for up to 70% of a typical commercial building’s energy usage.  Hospitals, fresh produce suppliers and restaurants will have an even greater energy consumption.    

•    HVAC systems and refrigeration units not only run longer under high ambient temperatures - they also draw more power whilst operating.
•    The only method to reduce energy usage is to make the HVAC systems run more efficiently by means of a pre-cooling system

Pre-Cooling Systems and How they work

Pre-Cooling systems include:

Coldmist nozzle-based misting systems – specifically designed around the HVAC units - installed and commissioned according to individual project requirements.

BENEFITS OF THE PRO-Series ROTARY ATOMIZER – no clogging of nozzles, no high pressure pump OR water filters required - minimal maintenance!

How Pre-Cooling works

• A  customized  evaporative fogging system is attached to each air conditioning unit which lowers the temperature of the air entering the condenser. This allows  the  condenser  to reject more heat  which lowers head pressures and compression ratios, thereby causing the compressor to draw less power, consume less energy, require less maintenance and last longer!

• The pre-cooling application performs best at the exact time when commercial buildings require increased refrigeration system performance – that is , during  peak heat. In fact, the higher  the ambient temperature, the greater the energy and cost savings potential.

Benefits of pre-cooling air conditioner condenser coils

  • Reduced energy costs
  • Reduced air conditioner maintenance costs
  • Increased peak cooling capacity
  • Reduced energy (kWh) usage
  • Reduced peak energy demand (kW)
