MAX-COND-RCVRYCRANKCASE-HEATCRANKCASE-MAX-TOUTS IDE-FAN-KWOUTSIDE-FAN-TOUTSIDE-FAN-MODECOMPRESSOR-TYPEHEATING-CAPACITYHEAT-CAP-FT*is the fraction of the heat produced in the condenser thatis to be recovered and is to replace active heating.is the amount of electrical energy, measured in kW, usedto heat the crankcase of direct expansion (DX) and heatpump compressors. The crankcase heater is on only whenthe compressor is off.is the outdoor dry-bulb temperature above which thecrankcase heater, if present, is not allowed to operate.is the amount of electrical energy, measured in kW, usedto operate the outside fan (condenser fan when cooling orevaporator fan when heating).is the outside temperature below which the condenserfan(s) are not permitted to operate.Input for this keyword is the code-word which describeswhether the outside fan operates continuously (CONTINUOUS)or only when the compressor is on (INTERMITTENT). Thiskeyword is appropriate only to RESYS, PSZ, PMZS, andPVAVS. Its default is INTERMITTENT.Input for this keyword is the code-word which describeswhether the compressor operates at only one speed (SINGLE­SPEED) or two speeds (DUAL-SPEED). This keyword is appropriateonly to RESYS.is the total capacity of the heating system (for RESYSthis HEATING-CAPACITY is at ARI rated conditions). Notethat the input value is a negative value. If the minussign is omitted an ERROR will occur. The program-designedHEATING-CAPACITY does not include fan power and heat.is the U-name of a bi-linear or bi-quadratic equation thatdescribes the heat pump heating capacity (dependentvariable) as a function of outdoor dry-bulb temperatureand entering dry-bulb temperature (independent variables).The bi-linear or bi-quadratic equation must be input tothe program and U-named in a CURVE-FIT instruction.Because the heat pump will seldom operate at the ratedheating rate, the equation identified by HEAT-CAP-FT isnecessary to describe the "shape of the change" in therated'* Input for this keyword should be made only if the user is not satisfied withthe default values built into the program. Additionally, if the user decidesto specify a U-name, it shoul d not be one of the reserved "Default CurveU-names" in Table IV.39. Furthermore, these U-names are applicable only tothe SYSTEM-TYPEs stated in the table.IV.249 (Revised 5/81)
