Webinput. Refrigeration systems require a work input to have a desired cooling load, which leads to a coefficient of performance (COP), defined as the cooling load divided by the work input. The COP is a non-dimensional measure of the performance of the cycle. The higher the COP, the better the system is. The maximum cannot exceed the Webrefrigeration systems such as those in supermarkets. • CFCs allow more ultraviolet radiation into the earth’s atmosphere by destroying the protective ozone layer and thus contributing to the greenhouse effect that causes global warming. Fully halogenated CFCs (such as R-11, R-12, and R-115) do the
