Optimization of the Thermal Transfer Capability of Single Fluid Heat Transfer System (SFHTS) using LabVIEW

摘要

To optimize cost and space in the pharmaceutical industry, it is desirable to heat and cool the utility fluid from the same equipment. The heat transfer for both heating and cooling is done using a single liquid. The system implemented with this concept is called Single Fluid Heat Transfer System (SFHTS). In this paper an actual SFHTS used by a pharma major company is considered. The essential objective is to eliminate overshoot and achieve set point in the shortest time possible, as the process ramp rate is approximately 1/minute. The real time SFHTS was simulated using LabVIEW software. PID and Sliding Mode Control (SMC) were applied to the heating and cooling module of the SFHTS. The results showed that SM Controller provided better control than PID Controller.
