Description

Design cooling load calculation methods are, by the nature of the processes they seek to model, complex, and they require detailed input data involving many parameters. Diag-nosing deficiencies in the calculation method or its computer implementation can be correspondingly difficult. A set of tests are proposed that are designed to exercise the principal features of any implementation of a design cooling load calculation method. Diagnosis of weaknesses of the method, or faults in its implementation, are made by making calculations with test data sets that induce a single type of heat gain or heat transfer by a particular path and comparison with a set of reference results for each test. In the tests proposed here, the ASHRAE heat balance method is used as a reference model. Details of the test input data specification are given along with the heat balance method results so that others can use the same tests. Some examples of how the tests were used in the project “Comparison of Cooling Load Calculation Methods (942-RP)” are also given.
