a green building must supported by a green construction which is not as easy as it seems. it is not a once-and-away construction but requires “green standards” to match its operation throughout the “full life cycle”. buildings energy efficiency standards, which is hopefully coming into effect at the end of 2014, will gradually supersedes government enforcement of the past and further establish the dominant position of market orientation.

the new evaluation standards for green buildings will be officially implemented on january 1, 2015. “the main difference between the old and new evaluation standards is the change from checklist system to scoring system which increases the difficulty to apply for 3-star green buildings.” said mr. lin haiyan, associate dean of china academy of building research. it is said that buildings energy efficiency standards and the new version of evaluation standards for green buildings will further elaborate policy guidance, enterprises incentive and subsidiary systems so as to push market progress for green buildings.in 2014 investments on energy efficiency in china will be well over four billion. by 2015 china’s new green building areas will be above one billion square meters and the share of urban green buildings will increase by 50% by 2020.

multistack oil-free chillers use oil-free magnetic levitation centrifugal compressors that represent the current leading compressor technology of the 21st century. oil systems are completely eliminated from the compressors; traditional mechanical bearings are replaced by magnetic bearings using top aerospace technology; motors, drive shafts and centrifugal impellers are levitated by magnetic fields without immediate contact with other parts to eliminate friction, efficiency loss, vibration and noise and to greatly improve compressors efficiency;

the oil-free compressor uses digital direct current variable frequency drive (vfd). its rpm changes with different loads which means the pressure ratio is variable. in comparison with the conventional constant frequency centrifugal compressor, oil-free compressor can achieve higher part load efficiency with outstanding adaptability to the changes of condenser and chilled water temperatures without any change on the compressor structure.

power consumption of oil-free chillers is 2/3 of that of traditional chillers and payback period is about 3 years, though the initial investment is higher than traditional ones.

as the pioneer of magnetic levitation technology in refrigeration industry and one of the earliest enterprises to launch magnetic levitation products, multistack’s magnetic levitation air-conditioning products receive a positive response and become the best selling products in southeast asian markets, going to every corner of the world.
