scope:

This standard

a. lists and defines the terms for rating the thermal performance and liquid-side pressure drop of evaporators used for cooling liquids;

b. establishes the methods of test that shall be used as a basis for obtaining the thermal performance and pressure drop of evaporators that operate at subcritical pressures of the evaporating refrigerant; and

c. applies to laboratory testing for purposes of rating evaporators within its scope. This standard is not intended for field testing of evaporators of any type.

PURPOSE

This standard prescribes methods of testing the thermal performance and liquid-side pressure drop of evaporators that operate at subcritical pressures of the evaporating refrigerant.
