ASHRAE 95

Abstract

This Standard applies to solar domestic water heating systems designed to heat potable water to be supplied for domestic water usage. <br>This Standard is not intended for other than solar water heating systems designed solely for domestic water usage. <br>The test procedures in this Standard are generally applicable to systems of 0.45 m³ (120 gal) storage capacity or less, and use demands on the order of 0.38 m³ (100 gal) of hot water per day, or less. <br>The test procedures in this Standard employing a non-irradiated solar collector array do not apply to an integral collector storage system, a system in which thermosyphon flow occurs, or to any system employing a collectodheat transfer fluid combination which cannot be tested in accordance with ASHRAE Standard 93-1986. <br>The test procedures in this Standard do not require the solar water heating system to be subjected to freezing conditions. Consequently, the energy consumed or lost by a system while operating in the freeze protection mode will not be determined. <br>This Standard provides the method of testing such systems for thermal performance. <br><strong>PURPOSE</strong> <br>The purpose of this Standard is to establish a uniform method of testing solar domestic water heating systems for thermal performance. <br>This Standard is not intended to beused for testing the individual components of the system. <br>This Standard is not intended to abridge any safety or health requirements.
