During the calendar months of April to September, many localities can experience periods of hot weather, when ambient air temperatures exceed 85°F. In many cases. hot weather can cause your air-cooled and water-cooled liquid chillers to decline in performance, and in some cases, not work at all.
The technical reason that this occurs is the design value of the chiller is exceeded during hot weather. Advantage chillers are designed to provide full capacity up to 95°F for air-cooled chillers and 85°F for water-cooled chillers.
There are some simple things that you can do to keep your chiller operating near full capacity when the ambient air temperatures exceeds the chiller's designed capacity.Air-Cooled Chillers
1. Keep the condenser coil clean.
2. Keep proper air circulation around the chiller. At least 4'-6' of clearance for the air inlet and discharge.
3. Keep adequate ventilation in the plant.
4. Keep good maintenance on the the fan, blowers and motors.Water-Cooled Chillers
1. Keep proper GPM through the condenser, at least 3 GPM at 20 PSI per ton.
2. Keep the condenser clean by preventing debris and biological growth from clogging the small tubes.
3. Keep the condenser water regulating valve (if equipped) is good maintenance.
