chillBooster is an adiabatic atomizer that uses evaporative cooling to cool the air before it is used by the condensing units such as chillers or dry coolers. The atomization of water in micrometric droplets favours spontaneous evaporation, which takes away part of the the thermal energy required for the evaporation itself from the surrounding air, lowering its temperature (each kilogram of water that evaporates absorbs 0.69 thermal kW from the air). Bringing the air close to its wet bulb temperature means that, during summer, its temperature is lowered by approximately 10-15°C with a consequent reduction of the workload required from the condensing unit (chiller), and therefore a significant energy saving in terms of spared electric kW. ChillBooster essentially consists of a cabinet with pressurizing pump (10 bar) and a system of nozzles mounted onto steel manifolds to be arranged around the condensing unit: the atomization occurs against the flow, so that the droplets, sucked in by the fan of the chiller, follow a longer route and have more time to evaporate. In this way, the air is cooled and the heat exchange of the battery is increased in depth. A part of the droplets will wet the flaps of the battery, absorbing the heat and then evaporating, thus increasing the heat exchange.
chillBooster can be used during summer, for maximum global energy saving, or it can be used to cut the peaks of maximum load on hot days, to maximise the efficiency of the chiller. As well as for retrofit applications, you can consider the effect of chillBooster also during the planning stage, by selecting the smallest, cheapest chiller with the lowest energy consumption. chillBooster is available in the capacities: 100, 500 and 1000 l/h. The nozzles have a capacity of 5 – 7.5 – 15 l/h. chillBooster can be used both with demineralized water and mains water, provided that the conductivity of the latter is not less than certain values
