High COP Water-Cooled Screw Chiller
3 4-7 9 High COP
The units are water-cooled chillers, designed from the ground up to meet the needs of today and tomorrow. It is distinguished for its chlorine-free refrigerant, high efficiency, high reliability, easy maintenance and low running cost. Born in 990s, is widely applied in all kinds of buildings such as hotels, offices, restaurants, schools, hospitals, enterprises, etc. Designed exclusively for R34a = R34a has zero ozone depletion potential. = R34a production is annually increasing, and has no expire date. Full/part load mode is more cost saving = 0N twin-screw compressor achieves high efficiency. = Carrier patent high efficiency flood evaporator increase heat transfer efficiency. = Multiple compressors allow flexible adjustment according to user's load, ensuring higher part-load efficiency. = Electronic expansion valve ensures high control precision. High reliability Two independent refrigerant circuits minimize unit shut down. Multiple compressors provide back up for each other. Complete protection function ensures the unit running smooth. Each unit has a trial run in the factory. Easy installation Compact design requires minimal indoor space. The maximum width reaches only 05mm, which allows the unit to fit through a standard door opening without disassembly. Evaporator and condenser short steel pipes and flanges are supplied by factory. Refrigeration and lubrication is filled ex-factory. The on-site installation requires only connection to water and power supply. Simple to service Graphical operational interface makes it clear and easy to operate. Screw compressor with few components requires low maintenance cost. Triple Sound Reduction Built-in sound reduction device can effectively reduce noises as result of high pressure air discharge fluttering by diverting the air in an appropriate way. New external muffler installed on the discharge pipe on the compressor can transform part of acoustic energy into heat and greatly reduce noise. (See the picture below) Sound reduction cabinet provides another sound-proofing barrier, and reduces the noise transferring to the machine room. (See the picture below) Muffler on Discharge Pipe nd Generation Sound Reduction Cabinet
PRO-DILOG Plus is an advanced numeric control system that combines intelligence with great operating simplicity. The PID control algorithm with permanent compensation for the difference between the heat exchanger entering and leaving temperature, anticipates load variations, guarantees leaving water temperature stability and prevent unnecessary compressor cycling. PRO-DILOG offers extended communications capabilities =Graphical interface, LED numeric displays make it clear and easy to understand. =Touch keys are well-positioned on the schematic chiller diagram, providing clear view of operation flow. ll operating parameters such as pressures, temperatures, operating hours etc are easy to use. =Operating menus provide direct access to acquiring and modifying parameters. PRO-DILOG has advanced control functions =llows local mode, remote mode and CCN mode to start/stop the unit. =The long-stroke electronic expansion valve (EXV), allows a significant energy efficiency improvement at part load conditions, and faultless chiller operation in a wider temperature range. =utomatic control of refrigerant circuits and compressors on/off status and loading sequence, thus equalizing compressor operating hours. =Interlock control between the unit, chilled water pump and cooling water pump, contributing to safe and high efficiency performance. = "Demand Limit" limits the maximum chiller capacity to a predefined value. This function is specially designed for multicompressor management, it aims to achieve the best running efficiency by imposing different chiller capacity limit to different compressors. =Evaporator leaving water temperature drop speed is controlled within the adjustable range (0.~. C/min) so as to avoid energy waste, improve ERR and increase unit life. =Provides a negative revision to cooling water leaving temperature according to outdoor temperature or return water tempera ture trend, so as to save energy and improve ERR by quickly fitting the wave trend of external load decrease. Safety Protection Function =Protection on low cooling water leaving temperature, low oil pressure, high refrigerant pressure, electric leak, compressor overload, high/low electrical voltage and phase lack. Multiple remote control =The communication bus between RS45 port of and the Carrier Comfort Net (need purchase) offers multiple remote control; the communication bus between and DTPORT communication module provided by Carrier (need purchase) realizes the connection with other building automatics.
