Standard Specifications High Efficiency Full Load Operation Utilizing new screw compressor technology, the chillers meet or exceed the performance requirements of ASHRAE 90.1. All system components are selected for optimum performance, including the condenser and evaporator sizes. Excellent part load performance Because the units are not operated in full load condition most of the time, integrated part load value
(IPLV is an important performance indicator as outlined in standard ARI550/590-1998. Thanks to the patented design of two system parallel connection technology, a excellent IPLV performance has been come true. Capacity control Step or stepless capacity control are optional available, enable the unit be turned on with the least load to reduce startup current; and match up capability output of the units to actual load, which make the units operate steadily and reduce operation cost. Compressor Compact suction gas cooled semi-hermetic twin screw compressors with high efficiency performance curve. Compressors are provided with high efficiency suction strainer, oil trainer crank case heater and built in safety pressure relief valve. Compressors are also provided with intelligent electronics including motor temperature monitoring, phase reversal protection, manual reset lock-out and discharge temperature protection by PTC`s sensors. Optimized oil management ensure minimum refrigerant dilution in oil. Cooler Flooded type, shell-and-tube type with refrigerant evaporated inside the shell and water flowing in the tubes. With special high efficiency pool boiling heat-exchange tubes, which are expanded into a steel plate, the flooded type structure enable both the theories of pool boiling and nucleation boiling be well applied. Thus, the uniform refrigerant distribution, optimized temperature field of heat transferring, heightened evaporating temperature are achieved, and cooling capacity and EER of the unit are improved greatly. All evaporator are designed, constructed, inspected, and stamped according to the requirements of the ASME Boiler and Pressure Vessel Code. Condenser The condenser is shell-and-tube type, carbon steel fin and seamless high efficiency copper tubes with Refrigerant condensing inside the shell and water flowing through the tubes. Each condenser is designed, constructed, inspected, and stamped according to the requirements of the ASME Boiler and Pressure Vessel Code. Reliable oil return In order to ensure the oil in refrigeration system returning to compressor, the secondary oil separator with both centrifugal and absorption setups is used for improving the separating efficiency of oil from refrigerant, and a kind of injection equipment of refrigerant is specially designed which can be a great help of oil returning into compressor from refrigeration circuit; At the same time, the low oil location protection is applied to avoid the damnification to compressor from low oil to ensure reliability of the chiller. Strict Out-going test Each unit will be tested strictly not only on nominal operation condition but also minimum/maximum operation condition when leave factory by advanced on-line test system. 4
Flooded Screw Chiller Technical Sales Guide Control panel The Control panel provides a friendly interface for the operator with the color touch LCD(liquid crystal display which can display chiller's operating status, diagnostic message and date curve. Superior Controls GREE has provided the latest technology in controlling the chillers. The control logic is designed to provide maximum efficiency, to help provide continuous operation in unusual operating conditions through proactive controls, and to provide the history record of operating to aid in trouble shooting. Protocol for integrating with your building automation system (BAS are optional available. 3.3 Standard Accessories New throttling setup The new throttle setup can calculate optimal value of EER through control logic and adjust it automatically from actual value to optimal value because refrigerant flux and the high of the liquid in flooded evaporator can be control accurately by electronic expansion valve the efficiency of unit will be maximized in either full load operation or part load operation. Water flow switch A water flow switch is available for field installation in the chilled water piping to protect against evaporator freeze-up under low, or no flow conditions. Interface are provided in the unit control center for field connection of the water flow detection switch. The flow detection device need to be prepared on field. Pump control output Provides a digital output to control the secondary chilled water pump. Standard unit has one pump control output. Unit on-off switch ON-OFF switch is provided for manually switching the unit control circuit. Indicator lights LED lights of indicating power on of unit, running state and fault indications. Filter drier Refrigerant circuits are kept free of moisture, sludge, acid and oil contamination by filter drier. Under voltage and phase protection Protects against low voltage as well as phase fault reversal. Sight glass An color indicator shows moisture contents and provides a mean for checking the system refrigerant charge volume. Liquid line solenoid valve It will be closed when the compressor is off to prevent any liquid refrigerant from accumulating in the evaporator. 5
3.4 Standard Control & Safety Devices Safety valve Protecting the unit against high discharge pressure. Compressor built-in protection device Motor winding temperature, discharge gas temperature and phase reversal for direction of rotation. Crankcase heaters Protects the unit against from refrigerant migration, oil dilution and potential compressor failure. 4 PRODUCT DATA 4.1 Ratings Model Capacity(kW / RT EER LSBLG190H-M 190/54 17.08 LSBLG90H-M 98/85 17.4 LSBLG35H-M 35/9 17.33 LSBLG430H-M 430/1 17.68 LSBLG480H-M 48/137 17.50 LSBLG550H-M 550/156 18.05 LSBLG650H-M 650/185 18.48 LSBLG780H-M 780/ 18.74 LSBLG850H-M 85/4 18.59 LSBLG960H-M 964/74 18.07 LSBLG1160H-M 1160/330 18.16 LSBLG1360H-M 1360/386 18.71 LSBLG1560H-M 1560/443 18.49 LSBLG1700H-M 1704/484 18.64 EER=Energy Efficiency Ratio at full load-the cooling capacity in Btu's per hour(btu/h divided by the power input in watts, expressed in Btu/h per watts((btu/h/watt. 6
