1These ratings are based on an outdoor relative humidity of 72%. They include an allowance for defrost but not for the supply air blower motor heat. Refer to the BLOWER PERFORMANCE
table for the KW rating of the supply air blower motor at the design conditions. Convert this KW rating to MBH using the following equation and add this equivalent heat to the heating capacity.
Blower Motor Heat (MBH) = Blower Motor KW x (3.415 MBH/KW)
Use the following equation to determine the C.O.P. at any operating condition:
C.O.P. = Total MBH (Including Blower Motor Heat)/[Total KW (Including Blower Motor KW) x 3.415]
2Correct the MBH and KW ratings with the following factors for different supply air CFM's.
3These ratings include the compressor KW and the following KW for the outdoor fan motor(s).
NOTE: Apply these factors to the above ratings before correcting
for the supply air blower heat and power requirements.
Blower motor KW is not included. Refer to the SUPPLY AIR BLOWER PERFORMANCE table for the KW rating of the supply air blower motor at the design conditions and add this power
requirement to the KW rating.
