System Performance Comparison
Table 17-18 is a study of the physical properties of several refrigerants indicating a common level of temperature operation of 0°F evaporator operation and 110°F condensing temperature on the high pressure side. The comparison includes an approximate evaluation of the centrifugal and reciprocating applications. Note that several CFC refrigerants are included, although they are being phased out and replaced by more environmentally safe refrigerants. These are left in the table at this time because they have been such common/prominent refrigerants in industrial applications.
