The Development of Dual-Effect Fuzzy Control System Based on FPGA

Abstract:

The water misting cooling has phase change characteristics,so the cooling efficiency is better than water cooled ,and more saveing energy、save water、less noise ,It is being widely used in the air conditioning system for the condenser cooling. In order to enhance the cooling efficiency of the water misting cooling system and improve the efficiency of the air conditioning system in the cold room, In the study use ultrasonic water misting cooling chiller for controlled object, and proposed the dual-effect fuzzy control system controller’s design concepts ,carry out the fuzzy controller and the control circuit in the FPGA chip to reach the goal of the product, After the relevant tests that is differing from traditional air-cooled water chillers. In the study, in addition to improve the shortcomings of traditional chiller energy consumption, to enhance the efficiency of water misting cooling system, achieve more saving energy and high efficiency control purposes.
