AHRI 410: Performance Rating of Forced-Circulation Air-Cooling and Air-Heating Coils

Standard Scope

This standard applies to forced-circulation air-cooling and air-heating coils as defined in Section 3.

This standard does not apply to: 

  • Forced-circulation air-cooling coils under frosting conditions 

  • Microchannel coils 

  • Bare tube coils 

  • Air-cooling refrigerant evaporator coils for direct-expansion refrigerant systems with refrigerant liquid flow controlled by:

    • Capillary tube assemblies 

    • Restrictor orifices 

  • Air-cooling refrigerant evaporator coils for flooded refrigerant systems 

  • Air-heating refrigerant condenser coils for refrigerant systems 

  • Indoor or outdoor refrigerant coils for heat pump refrigerant systems 

  • Forced-circulation air-cooling and air-heating coils for airside fluids other than air 

  • Non-round tube coils
