Coolerado H80

Coolerado H80: Overview of Operation

Coolerado’s hybrid system couples indirect evaporative cooling with two stage vapor-compression cooling. The indirect evaporative cooler can operate alone or it can act as a pre-cooler for the vapor-compression system. When the compressor operates, exhaust from the indirect evaporative cooler is used for condenser cooling. The indirect evaporative cooler used for the system is an integral device with multiple air pathways that exchange heat and mass to cool supply air without the addition of moisture. Motorized dampers control the balance of outside air and return air, and the system operates with a minimum outside air fraction of approximately 45%. Variable speed supply fans for both supply and exhaust allow enable part load operation when only a fraction of the full load capacity is needed.

Summary of Performance

The Coolerado H80 was tested for Western Cooling Challenge certification at the National Renewable Energy Laboratory, in Colorado. The results show outstanding performance, indicating that the H80 could outperform federal standards for conventional equipment by 65%. The figure below provides some key information about system performance in each operating mode and at each Cooling Challenge test condition. The results are compared to performance at these conditions for a similarly sized conventional rooftop packaged unit.

Just ordered Corsair H80...

The prime piece of the upgrade to my rig, once I install the H80 I can finally swap the stock northbridge chipset heatsink which is just a fancy EVGA aluminum black coated fin, to a Thermalright SLI northbridge heatsink. I installed it before and the temps was amazingly lowered by 20 Celsius with the help of a Coolermaster 80mm fan with a nice blue LED. Dramatically helped my overclocking heat issue. Other issue, was that I could only install that heatsink if I horizontally position my CPU heatsink. Due to my PSU is position above the motherboard, it’ll just cause rising heat to go up and down between CPU and PSU. With the H80, it will give me the maximum head space for the Thermalright SLI northbridge heatsink. While I am doing these swaps, I’m going to replace the thermal tape that I mistakenly forgot to peel tape on the other side for my mosfet heatsink.

Watch on
