Methods of Testing for Rating the Performance of Positive Displacement Refrigerant Compressors and Condensing Units That Operate at Subcritical Temperatures of the Refrigerant
Despite the change in its title and designation, this proposed 'new' standard is actually a revision of ASHRAE Standard 23-2005, Methods of Testing for Rating Positive Displacement Refrigerant Compressors and Condensing Units. Standard 23 has been revised, renumbered, and given a new scope because ASHRAE is developing a companion standard, Standard 23.2, which will address the testing of positive displacement compressors and condensers using refrigerants like CO2 that operate at supercritical temperatures. This draft revises Standard 23 to restrict it to the testing of such equipment using refrigerants that operate at subcritical temperatures.
