ASHRAE 94.2-1981 (RA 2006) PDF

This is a reaffirmation of ASHRAE Standard 94.2-1981. This standard falls under the Standards Committee classification of Standard Method of Measurement. This standard was prepared under the auspices of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). It may be used, in whole or in part, by an association or government agency with due credit to ASHRAE. Adherence is strictly on a voluntary basis and merely in the interests of obtaining uniform standards throughout the industry.

There are essentially two types of heat storage devices in existence that can be tested by this standard: central devices and room devices. Central devices are located at a central location from which their output is ducted or piped to the point of use or to a heat exchanger. Room devices are installed within the space to be heated; they are sometimes referred to as radiator devices because they release their heat by either radiation or convection or a combination of the two. Separate testing procedures are prescribed for the two types of storage device.
