ASHRAE Standard 30-2019 Method of Testing Liquid Chillers
ASHRAE Standard 30 prescribes methods for obtaining performance test data of liquid-chilling or liquid-heating equipment using the vapor compression thermodynamic cycle and any type of compressor. The intent of this standard is to provide uniform test methods to measure the performance of this equipment by specifying the test and instrumentation requirements, test procedures, data to be recorded, and calculations to generate and confirm valid test results. Changes since the 2017 edition include the following:
- Clarification of operating condition tolerance and stability criteria when redundant measurements are required
- Reference to ANSI/ASHRAE Standard 41.8 for liquid mass flow rate measurements
- Clarification that test instrument measurement resolution includes all parts of the measurement system, such as analog to digital conversion
- Updates to Section 9 test report requirements to align with AHRI Standards 550/590 and 551/591

The purpose of this standard is to prescribe methods of testing to measure the thermal capacity, energy efficiency, and water pressure drop of packaged liquid-chiller equipment
using a refrigerant vapor compression cycle. This standard does not specify methods of establishing published ratings or performance tolerances.
This standard applies to liquid-chilling or liquid-heating packaged equipment using any type of compressor and using the following methods of heat rejection during the cooling cycle: a. Air cooled,b. Evaporatively cooled & c. Water cooled
gross cooling capacity: the capacity of the evaporator as measured by the total heat transferred from the liquid to the refrigerant in the evaporator. This value includes both the sensible heat transfer and the friction heat losses from pressure drop effects of the liquid flow through the evaporator.
