Where:
 

COOL −CAP − FT = PTAC cooling capacity at off­design conditions

COOL − EIR − FT = PTAC full load power consumption at off­design conditions

COOL − EIR − FPLR = PTAC power consumption at part­load conditions

Heat −CAP − FT = PTHP heating capacity at off­design conditions

HEAT − EIR − FT = PTHP full load power consumption at off­design conditionsHEAT − EIR − FPLR = PTHP power consumption at part­load conditions

WB = entering coil wet­bulb temperature (°F)

EDB = outside dry­bulb temperature (°F)

DB = entering coil dry­bulb temperature (°F)
