Temperature control is an important factor which influences the accuracy of refrigerant heat transfer experimental results. In this paper, three temperature methods for electric heating water tank (EHWT) in single tube rig are investigated. The error PID controller ? 1?C and stability time 390s. performance not satisfactory. A fuzzy a designed to improve performance. controllers simulated by Ma...
