With up to 30% energy savings
Fes Chill Units evaporatively cool the inlet air of air cooled condensers at very low costs. Evaporative cooling pads, which are simply installed in front of any air cooled condenser, are kept constantly wet by a small water circulation pump. The existing fans of the condensers cool the hot air by passing the outside hot air over the wet pads, bringing the hot air closer to the wet bulb temperature. This cooled air passes over the condenser pads. Thus, the operation of the condenser is relieved, the cooling performance of the condenser increases, the energy consumption of the cooling groups decreases, the operating performance of the system increases, the operating pressure decreases, the life of the system and the compressor is extended, and the risk of failure is reduced.
Cooling of the condenser inlet air reduces the system operating pressure and the energy drawn by the compressor, increasing the cooling capacity. (For 26 kW Air Cooled Chiller Group with R22 Gas)
The gain rates obtained as a result of comparing the values taken before and after pre-cooling the condenser of the Chiller unit with FesChill units are shown in the table above. As a result of lowering the inlet air to the condenser by 11 ̊C after pre-cooling, the electrical power drawn by the Chiller decreased by 19%; cooling capacity increased by 11%. The COP of the chiller also increased by 36%. Every 1.8°C decrease in air temperature due to pre-cooling provides a 2% increase in condenser efficiency.
