scope:

This standard covers electric, air-to-air, space-conditioning appliances that include a refrigerant-to-water desuperheater and have rated cooling capacities of less than 65,000 Btu/h.

PURPOSE

This standard provides test methods and calculation procedures for establishing the efficiencies of space-conditioning/ water-heating appliances having refrigerant-to-water desuperheaters.

The procedures may be used as a basis for establishing efficiency ratings for such equipment and for estimating annual energy consumption.
