13、 test (cooling) are also verified initially by test for manufacturers applying into the AHRI ULE Certification Program. Foreword: AHRI Standard 340/360 2015 contains many significant revisions to the 2007 standard. 1. The revised standard includes definition and test requirements for Double-duct com
14、mercial unitary equipment. 2. Definitions have been expanded and clarified including an updated definition for IEER. 3. Table 1, Classification of Commercial and Industrial Unitary Air-Conditioner Equipment has been rewritten for clarity. 4. Table 2, Classification of Commercial and Industrial Unita
15、ry Heat Pump Equipment has been rewritten for clarity. 5. The part load efficiency, IEER, test method is simplified by eliminating the iterative OD test conditions needed to achieve a desired load point. The new method requires an additional test point at known conditions to be run in order to inter
16、polate to the desired load point. This simplifies the test procedure (Table 6). This method also reduces the uncertainty with the addition of a 3% tolerance for part load percent. 6. Section 5, Test Requirements, has been expanded to cover items not documented in ASHRAE Standard 37. 7. The standard
17、adds a tolerance of 3% on required part load Percent Load point where interpolation and degradation is not required (Table 7). 8. The revised standard includes optional International Rating Conditions (Section 6.3) relevant to international requirements that may be used optionally. The Rating Condit
18、ions are intended to align with ISO 5151, 13253 and 15042 conditions. 9. The standard includes a step by step procedure to generate IEER ratings based on either test method or computer simulation. This also includes clarification on procedures for fixed, capacity, staged capacity and variable capaci
19、ty units (Section 6.4). 10. Verification test uncertainty allowances have been explained and clarified for the performance metrics in the standard.
