An Experimental Evaluation of Refrigerated Display Case Performance

Refrigerated display cases are now commonplace in food stores in order to display products in an attractive manner to the customer. An increasing variety of chilled and frozen foods has also added to the demand for more chilled display area but despite this, most modifications to the way supennarket refrigeration systems are designed has come on the high pressure side with little or no regard for what is happening within the display case on the sales floor. The aim of this paper is to present the results of some experimental work earned out at Bnmel University on a vertical daiiy display case. It is envisaged that this work will help us to understand in greater detail what happens inside the case and how it interacts with its environment.
