ASHRAE STD 20
Methods of Laboratory Testing Remote Mechanical-Draft Air-Cooled Refrigerant Condensers
|Publication Date:||4 January 2019|
This standard provides
a. methods of laboratory testing for obtaining performance data,
b. definitions of terms,
c. specification of data to be recorded,
d. calculation formulas, e. test limits and tolerances, and f. apparatus and instrumentation with associated accuracies.
This standard does not cover a. methods of test for production or field use;
b. heat exchangers that do not fully condense refrigerant vapor, as in heat reclaim applications;
c. methods for rating condensers; or
d. external air resistance devices not provided by the manufacturer.
This standard prescribes methods of laboratory testing remote mechanical-draft air-cooled refrigerant condensers.
