Multiple ASHRAE Standards Updated
From eSociety, December 2017
From incorporating addenda to adding more information, read about how Standard 30-2017, Method of Testing Liquid Chillers; Standard 140-2017, Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs; Standard 161-2018, Air Quality within Commercial Aircraft; Standard 170-2017, Ventilation of Health Care Facilities; and Standard 194-2017, Method of Test for Direct-Expansion Ground-Source Heat Pumps, were updated.
Standard 30-2017, Method of Testing Liquid Chillers
ASHRAE Standard 30 prescribes 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. The standard was last revised in 1995.
Standard 140-2017, Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs
Standard 140 specifies a standard method of test for evaluating the technical capabilities and applicability of software used in calculating the thermal performance of buildings and their HVAC systems. The revised 2017 edition of Standard 140 includes all the test cases of Standard 140-2014 and adds a set of analytical verification test cases for evaluating air-side HVAC equipment models. The 2017 edition includes online access to electronic supporting files.
Standard 161-2018, Air Quality within Commercial Aircraft
The revised 2018 edition of Standard 161 includes a new Section 10 with a standardizing reporting form to assist maintenance workers in their troubleshooting process, and the updated standard provides more guidance related to maintenance protocol for checking and adding oil to APUs. Standard 161-2018, Air Quality within Commercial Aircraft, defines the requirement for air quality in air-carrier aircraft and specifies methods for measurement and testing to establish compliance. It is available now electronically and will be available in print on Dec. 21.
Standard 170-2017, Ventilation of Health Care Facilities
The 2017 edition of Standard 170 incorporates 12 addenda to the 2013 edition and has been reorganized into three sections – hospital spaces, outpatient spaces and nursing home spaces – to align with the forthcoming 2018 FGI Guidelines. Standard 170-2017 includes the following changes:
• Addition of adiabatic humidifiers as an acceptable type
• Addition of a new type of exam room with lower requirements for less-acute applications
• Clarification around the prohibition of controls to change pressure relationships between
spaces
• Reduction in requirements for electroconvulsive therapy procedure rooms
• Reduction in requirements for laboratories when allowed by certain calculations
• Higher requirements for higher hazard exhaust airstreams
• Coordination of space temperature requirements in the Sterile Processing Department with
other industry groups
• Clarification of the definition of the primary diffuser array in operating rooms
