Centrifugal Chiller-High efficiency series
The third generation "Smart Star" centrifugal chillers with higher efficiency and more compact size compared to the second generation. By using the advanced design platform the compressing efficiency and heat exchanging rate were increase significantly. The full failing film heat exchange technology also be use to increase the efficiency and decrease the refrigerant charging volume up 40% less compared to the flooded type. It is a innovation to protect our environment and decrease the CO2 emission effectivly. 650KW to 1100KW models adopt one compression stage. 1200kW to 2200kW models adopt two compression stage. Flooded type and full falling film type evaporator are available.380V/3N/50Hz and 10kV/3N/50Hz both can be customized. COP is up to 5.6~6.8.
■ Unique designed dual stage compression technology enhances the heat absorption capacity of refrigerant, and lowers the power consumption, which increases 6% of efficiency over the single stage compressor.
■ Dual stage impeller is an equal ratio compression design, which helps to reduce the rotate speed and enhance the reliability.
■ Unique three-stage separation economizer simplifies the system design
The microcomputer control system has such as the trend prediction, self-diagnosis, self-adjustment and safety protection. capable to predict real load change according to the target values and historical load levels, prospectively modify the operation load and prevent energy waste
High efficient heat-exchanger and optimized structure enhance the heat exchanging performance. The design of reverse flow sub-cooling chamber with multiple turbulences increases the sub-cooling degree and improves the performance.
The unique full falling-film evaporating technology: spraying technology makes the liquid refrigerant form and evaporate on the surface of evaporating tubes, which significantly boosts the heat-exchanging efficiency and reduces 40% refrigerant charge. Olyair adopts patented technologies to ensure refrigerant distributed evenly and avoid non liquid on part tubes, which extend the potential heat-exchanging capacity to the full and enhance the efficiency of the whole system.
