Standard 137-2013 (RA 2017) -- Methods of Testing for Efficiency of Space-Conditioning/Water-Heating Appliances that Include a Desuperheater Water Heater(ANSI/ASHRAE Approved)
标准137-2013(RA 2017)——包括减温器和热水器的空间调节/热水设备的效率测试方法(ANSI/ASHRAE批准)
ASHRAE Standard 137 provides test methods and calculation procedures to determine the efficiencies of space-conditioning/water-heating appliances with refrigerant-to-water desuperheaters. The standard acts as a basis for establishing efficiency ratings for these equipment and for estimating annual energy consumption.
