Oil-Free design Optimizes heat transfer The well-known ASHRAE study concluded that typical lubricated chiller circuits show reductions in design heat transfer efciency of 15-25%, as lubricant accumulates on heat transfer surfaces, denatures and blocks normal thermodynamic transfer processes. Logically, no oil in you chiller means no oil contamination over time, so design efciency is maintained efortlessly. Advanced electronics Advanced electronics mean that mechanical forces can be managed with extraordinary tolerances, achiev- ing very high reliability. Not a surprise, when shaft position is automatically measured and adjusted 100,000 times per second. Inverter driving The inverter centrifugal compressor adopts the integrated driving module. on the condition of condensing temperature decreasing or load reducing, lower the compressor revolution then optimum the compressor energy efciency with 10% - 100% of rated load. Energy cost savings Compared with a new screw chiller, Our Centrifugal Turbo Chiller IPLV efciency is routines more than 32% better. Compared with older lubricated reciprocating, screw, scroll or centrifugal chillers, year round savings with Our Centrifugal turbo chillers can be spectacular, with over 50% savings. Under ARI conditions, The IPLV performance can be as high as 11.0 COP while partload-efciency can be over 13.0 COP.
|Turbocor compressor technology The chillers either water-cooled or air-cooled, are designed to optimize the performance of the high efficient danfoss turbocor oil-free centrifugal compressor technology.|
|Permanent-magnet motor and Landing bearing The compressor motor is magnetic permanently, which is supplied voltage by PWM (pulse width management) to realize variable speed running. The landing bearing will go upward before the unit starts up, which will keep a certain distance automatically and ensure no friction.|
|EEV (electronic expansion valve) Adopt electronic expansion valve. It will control the volume of liquid refrigerant spraying into the evaporator precisely. Adopt the special electronic expansion valve driving module, which will control the stepping motor operation due to the different load, adjust valve open angle, control refrigerant flow volume, and control the compressor, evaporator and condenser running at the optimum efficiency.|
