AutoCool Evaporative Rooftop Cooling

Evaporative roof cooling will lower a roof's surface temperature 50-70 °F during the summer days. This amounts in an estimated 20-30% reduction of the buildings total heat load. In other words, the air conditioning lasts longer and works less, thus reducing the amount of energy required to cool the facility.

At the current average electric rates in California, an evaporative roof cooling system will have an estimated payback of 12-14 months by reducing the energy demand 20-30%. Other states will have paybacks in as little as 2 years. In the case of new construction, the total installed air conditioning tonnage can be reduced, with a further savings in capital expenditures. There are also circumstances when rooftop cooling supplies sufficient relief, eliminating the need for conventional air conditioning.

UV-stabilized PVC piping connects a series of misting nozzles on the building's roof. Roof sensors provide feedback to the AutoCool computer, which in turn toggles solenoid valves that supply precise amounts of water to the roof. The AutoCool software maximizes the cooling and minimizes water consumption. Additionally, the AutoCool software provides on screen strip chart recording of temperatures as well as historical reporting. AutoCool also calculates water consumption, energy savings and payback.

Configuration Screen

Note the simple "fill in the blanks" approach to configuration. No programming skills are needed. One of the many unique features to AutoCool is the "S-Factor". This is a tuning parameter used to maximize cooling and minimize water consumption. Each roof will have it's own optimum S-Factor ranging from +1 to -1. AutoSoft engineers will provide a starting point based on the type and angle of the roof. Also note that AutoCool has an automatic winterization algorithm. In the case of an unexpected and sudden temperature drop, AutoCool will automatically purge the manifold of water by turning on an air compressor and methodically blow out the entire system. This air purge can be operator initiated at the end of the cooling season.

Graphical Report Example

All reports are exported to Microsoft's Excel for ease of use. Standard Excel workbooks are generated, further manipulated, saved, and/or emailed as any other Excel document.

The computer hardware uses the Windows XP Pro operating system and can be networked and controlled using the standard Windows network and Remote Desktop Connection protocols. AutoSoft engineers can rapidly assist in configuration and troubleshooting using these industry-standard tools over the Internet.
