AHRI STANDARD 210/240
Cooling or heating capacities are net values, including
the effects of blower motor heat, and do not include
supplementary heat. Power input is the total power input
to the compressor(s) and fan(s), plus any controls and
other items required as part of the system for normal
operation.
Units which do not have an indoor air-circulating blower
furnished as part of the model, i.e., split system with
indoor coil only, is established by subtracting from the
total cooling capacity 1250 Btu/h per 1,000 cfm, and by
adding the same amount to the heating capacity. Total
power input for both heating and cooling is increased by
365 W per 1,000 cfm of indoor air circulated.
