Combined Cooling Heat Power (CCHP) in Refrigeration Applications - A Case Study

摘要

This paper concerns the subject of cogeneration or combined cooling heating, and power (CCHP) first presented to the Institute in 1995 by Tozer & James. The original paper focussed on the application of CCHP in air conditioning. The requirements of lower temperatures of process/food applications make the integration of CCHP in refrigeration distinct from air conditioning. The application of lower temperature CCHP is addressed in this second paper. The paper specifically uses a refrigeration application, the supermarket to introduce the technology suitable for lower temperature CCHP. The paper then defines the cooling, heating and power requirements of the supermarket. It describes a model that has been developed to investigate the CCHP options available. Finally the paper describes the evaluation of these schemes and results are shown to define their economic and environmental viability compared to conventional methods of providing cooling, heating, and power.
