2.1 This standard prescribes an entire-scale laboratory exam strategy for measuring the general performance of in-duct sorptive media gas-period air cleansing devices. With this context, sorptive media are defined because the Lively agent with the air cleaner, whether or not granular or sheet or pleated, that run by absorbing and/or chemically reacting with contaminant gases.
one. Intent: This regular establishes a uniform approach to laboratory screening for rating central-process household humidifiers.
The purpose of this typical is to offer methods for laboratory testing of fault detection and diagnostic (FDD) devices to ascertain whether they carry out as specified.

2.two The outcomes acquired with the prescribed methods are indicative in the refrigerant flow properties in the tube but are usually not intended to characterize the actual refrigerant stream properties inside of a refrigerating cycle.
Suitable credentialing conditions for people making use of this regular and reporting constructing Strength use.
2.one This typical applies to the FDD techniques which are meant to detect or diagnose faults that have an impact on the overall performance of the air-aspect economizers of air conditioning devices.
one. Intent: The goal of this conventional is to deliver test solutions for figuring out the thermal overall performance of solar energy collectors that use solitary-section fluids and also have no major inner Electricity storage.
two. SCOPE: This regular applies wherever all the movement stream of your refrigerant both of those enters and exits the flowmeter both like a ‘vapor only’ or ‘liquid only’ condition.
