Development of Supersonic Vaporization Cooling System for an Air-cooled Chiller

This paper provides a new cooling method for the water misting cooling. Differing from traditional air-cooled water chillers, this study aims to achieve power savings and improved efficiency by improving the cooling method and power consumption index of traditional air-cooled water chillers. In order to prevent scaling issues from occurring during the atomization of oscillator operation, a filter is provided at the water inlet to reduce scale generation. Furthermore, the system uses a high-performance pollution-free HC refrigerant, combined with an atomizer at the high-pressure side (condenser), driving the mist to flow evenly along the condenser by the unit fan and condenser fan, for lowering the temperature. Since this equipment reaches the cooling demand shortly, the compressor tends to start/stop frequently; this is disadvantageous to the compressor, therefore variable-frequency will be considered to address the frequent start/stop issue so as to perfect the combination.
