Managing condensing temperature to improve the efficiency of refrigeration system

Abstract

The mechanical vapour recompression type of refrigeration system is most common in the food processing industry, in which condenser working conditions greatly influence the overall efficiency of the refrigeration system. Effectiveness of the refrigeration system to a great extent depends on the efficiency and economy of heat rejection by obtaining desirable condensing temperature. Increase in the condensing temperature results in reducing the economy of the refrigeration system. Various influencing factors, including temperature and flow rate of cooling water, heat transfer coefficient and heat transfer surface are very significant. Hence, attempts to optimize the temperature of cooling water along with the cleanliness of heat transfer surface are productive and desirable preventive operations for the economical generation of refrigeration effect towards quality and cost effective supply chain management.
