碩士 === 國立臺南大學 === 機電系統工程研究所碩士班 === 101 === In this paper, improved controls for the refrigeration and air conditioning equipment,traditional air-cooled, water-cooled, and evaporative condenser form mainly are for the use of evaporative cooling system, evaporative using high pressure nozzle as a cooling, however, because of the high-pressure jets of water particles and could easily lead to environmental pollution, noise, so in order to improve these problems, but alsotake into account the energy-saving aspects of the problem, so this study will be to replace the high-pressure nozzle ultrasonic mist, and ultrasonic mist oscillator as a controlled body, and put forward the concept of dual-effect fuzzy control system, use Field Programmable Gate Array (FPGA) chip to achieve dual-effect fuzzy control system design and production. Because the FPGA has a simple calculation and the use of inclusive high characteristic, so in our study use the FPGA of dual-effect fuzzy controller platform, and use one chiller to verify the feasibility and effectiveness of dual-effect fuzzy control system. But the water-misting is not easy to measure, so the study will use the digital image to measure the area of the mist , and establish the relationship of water-misting、input power and temperature .
