Condenser Performance on hot summer days

Air-cooled refrigeration and air-conditioning systems perform at their very worst at the exact time when they are most needed. On hot summer days, the same system that produces 95 tons of cooling when the ambient temperature is 85F°/29°C, produces just 82 tons at 115°F/46°C. That equates to a 14% reduction in capacity. Over this same temperature range, the power draw increases by 31%!

As ambient temperatures rise, air-cooled systems find it increasingly difficult to reject heat. As a result, cooling capacity falls, systems must run longer to reject the same amount of heat, and compressors draw considerably more power when they run. This combination of increased run time, increased power draw, and reduced cooling capacity translates to lower efficiencies under peak ambient conditions.

Historically, technicians have resorted to placing water sprinklers under condensers to increase cooling capacity. While this does indeed work at some level, uncontrolled water flow can cause water and sewerage costs to rise and result in roof leaks.

To improve on this practice, we have developed Green Energy Mist – a cost-effective method of improving the performance of air-cooled air conditioning and refrigeration systems without the negative effects associated with sprinkling water on condensers.
