RN E-Box Variable Capacity Base offering has variable speed compressors on half of the cooling circuits Option for variable speed compressors on all of the cooling circuits 208 & 230V Applications can modulate between 35-60 Hz 460 & 575V Applications can modulate between 35-75 Hz RN-140 limited to 60 Hz for all voltages
RN E-Box Variable Capacity VFD compatible compressors VFD speed control condenser fans optional Hot gas bypass not required with variable speed compressors AAON VFD s only AAON controls only
RN E-Box Variable Capacity Advantages of variable speed control Higher part load energy efficiency Reduced starting current due to soft start Reduced mechanical stresses due to soft start Reduced refrigerant pressure fluctuations Smaller compressor size on 460 & 575V applications due to 75 Hz operation Quieter compressor operation at reduced capacity
RN E-Box Part Load IEER has the following weighting: 100% capacity 2% 75% capacity 61.7% 50% capacity 23.8% 25% capacity 12.5% IEER comparison RN-060 with 6 row evaporator: EER = 10.6 & IEER = 12.3 RN-105 with 6 row evaporator: EER = 10.3 & IEER = 13.3 Notice the higher IEER value for the variable speed compressor RN E-box even though the full load EER is lower
Thermal Efficiency..
High-Performance Polyurethane foam-insulated Composite Panel Double-wall metal Polyurethane foam R=6.25 per 1 Thermal- break (1/8 EPDM seal
High Performance Composite Expanded Foam Panels Polyurethane foam panels using 24-gauge sheet metal are stronger and more rigid than typical double-wall construction Composite panels with solid foam core result in 25% less weight Offered at the same price as standard single-wall fiberglass insulated construction NO ADDED COST! No exposed insulation to erode and enter the air stream Thermal break prevents indoor and outdoor metal contact, thus eliminating condensation, and promoting energy-efficiency Now available as standard construction on all RQ, RN, RL, LL, CL, BL, SA, M2, and M3 Series units.
