Development of a supersonic mist-cooled chiller based on dual-fuzzy control

摘要

Global warming and fossil fuel exhaustion are deteriorating even further, of which energy saving and carbon emission reducing are the most critical. In a building, about 40% to 48% of the total electricity used is consumed by air conditioning systems. A novel water-misting cooling condenser based on supersonic vibrators with dual-fuzzy control was developed. The simulation studies and experimental tests based on a 12,500 Kcal/h air-cooled chiller platform were completed. The results from above studies and tests consistently shown that the proposed condenser is an excellent solution to pull up the energy efficiency for the cooling system. In addition, the inherent drawbacks of current chillers such as water noises, taking-up space, and unnecessary energy consumption caused by improper controls between compressor and condenser can be improved by this proposal.
