The development of low energy integrated commercial refrigeration.

Author(s) : COX N., CLOSE-BROOKS O.

Summary

The paper describes the work carried out between April 2004 and September 2005 under the title "The development of low energy integrated commercial refrigeration technology". The project brief was to investigate a new supermarket refrigeration concept named the "Integrated chilled water loop" or ICWL and to compare its performance to refrigeration systems described in an EA Technology study. This involved constructing a supermarket refrigeration test rig, choosing a refrigerant, monitoring the performance of the test rig and comparing it to that modelled in the EA Technology study. The ICWL is effectively a cascade refrigeration system consisting of a water chiller and a chilled water loop which cools low temperature and high temperature condensing units which in turn provide the store refrigeration. Five refrigerants were compared, the first being the synthetic HFC refrigerant, R-404A. The rest were natural hydrocarbon refrigerants.
