30 XA/30 XAS Air Cooled Screw Chiller
COP Reaches 3.2 Reflecting The Optimum Efficiency Performance
Carrier has successfully developed 30XA Air-cooled Screw Liquid Chiller leading the industry, with the full load refrigeration efficiency of 3.2 and the premium part load efficiency, by utilizing the innovative conception. The excellent refrigeration performance makes 30XA reach the new height of air-cooled products - Grade 2 energy efficiency.
Highly Efficient Twin-Screw Compressor
With decades of successful experience in developing twin-screw compressor, Carrier has successfully developed the new 06T highly efficient twin-screw compressor specially tailored for HFC-134a refrigerant.
Take an office building for example, the total cooling load is 1700 kW. When using two 30XA852 chillers, the 8% of energy can be saved, if compared with the product with Class 3 energy efficiency, and with those of Class 3, the energy saving can reach 14%.
MCHX condenser (optional)
Carrier applies the micro-channel heat transfer technique used in aviation and automobile to the central air-conditioner successfully for the first time. The heat transfer efficiency is improved by 10% and the air resistance is reduced by 50%, compared with conventional copper-aluminum fin coil. The full-load cooling efficiency of the chiller shall rise by 2% and the energy saving effect is much better.
Human-Friendly Design Saves The Installation and Repair Time
The compressor is erected on the slide track to facilitate on-site maintenance and repair, to save the maintenance time after stopping the equipment and provide more human-friendly services.
Microcomputer Control to Simplify The Operation
Pro-Dialog Plus microcomputer control system specially designed for the air-cooled liquid chiller perfectly features the easy and convenient operation and the advanced ad complicated control concept for the central air-conditioner. The system monitors all operating parameters and safety device in real time, precisely manage the compressor, electronic expansion valve, fan and pump (built-in hydraulic module for option), to make the chiller operate with the optimum energy efficiency.
Comprehensive Improvement of Silencing Performance
- Minimum noise is only 61 dB (A)*
*Measured value of 1000kW chiller
Optimized Design Brings New Standard of Silencing
The 4th generation “Flying Bird” low noise axial fan, low noise double screw compressor and vibration reduction installation, optimized fin coil, silencing box of compressor and low speed fan options, advanced design concept and successful application of new technique makes 30XA become one of the quietest products. At the distance of 10m, the chiller with cold quantity of 1000kW is only 61dB(A). What is most commendable is that 30XA realizes the perfect combination of excellent silencing performance and splendid cooling performance.
