Abstract

Waste heat recycled from supermarket refrigeration systems (SRS) exhibits a potential heat source that can supply the required heat to the supermarket or sell to the district heating system (DHS), thereby reducing the gross heat costs. This paper presents a cost-effective heat recovery control (HRC) for the heat recovery unit (HRU) integrated into SRS. The basic idea is to manipulate dynamically the amount of heat recovery by minimizing the real-time heat recovery cost based on quantifying heat production of SRS and dynamic energy prices. Moreover, a field test is conducted based on data communication between a master control computer executing the proposed control strategy and remote monitoring SRS. Experimental testing results and comparisons with other simulation cases demonstrate that the proposed method could promote a cost-effective heat recovery for SRS.
