Empirical modeling and robust control of a novel meso-scale vapor compression refrigeration system (mVCRS)

This paper presents an empirical modeling and robust control of a novel meso-scale vapor compression refrigeration system (mVCRS). The objective of this study is to maintain a temperature of heat source via the mVCRS against the cooling loads varying from 30 W to 80 W. To this end, the proposed mVCRS is identified by using a black-box model under various cooling loads and the robust control system is chosen to achieve the desired cooling capacity and the temperature tracking capability. For various cooling loads, the experiments using the mVCRS are carried out, which demonstrate that even for its compactness, the maximum cooling load of proposed mVCRS is 80 W with maintaining the temperature of the heat source around 46 °C with the help of a robust controller and, the temperature of heat source converges to the desired one within 70 sec and is minimally bounded by 1.25 °C irrespective of the cooling load.
