POTENTIAL ENERGY SAVINGS USING DYNAMICALLY OPTIMISING CONTROL IN REFRIGERATION SYSTEMS UNDER DAILY VARIATIONS IN AMBIENT TEMPERATURE

摘要

The objective of this study is to investigate the energy saving potential for refrigeration systems by refrigeration more at the colder night time than at the warmer day time. The potential is evaluated using an optimal control policy and illustrated on a simulation example. The results show that the significant potential savings depends on two system parameters and the variation of the outdoor temperature. The system dependency is illustrated in a parameter study.
