Description

Screw air-cooled chiller(or heat) is the unit which in order to the cooling medium (summer) and heat (winter ) water as the refrigerant cold ( hot) water. It can join with fan coil units, air conditioning box, air processor together make up half of concentration and centralized the central air conditioning system; Single cold- screw air-cooled chillers are widely used in various fields of industrial refrigeration. 

1. Compare with water chiller: Compare with water chiller, it saves a huge Cooling water system. And it also don`t need a Special air conditioning room. 
2. Precise stable water temperature: As used for industrial cooling, Low temperature water which produced by air-cooled chiller could send to the equipment and containers directly which need to be cooling. 
3. Achieve annual refrigerate operation: In the industrial cooling use aspect, Screw air-cooled chiller can use in above temperature **0° C. Achieve annual refrigerate operation, In order to meet the industrial cooling in the winter refrigeration requirements. 
4. Y-depressurization start mode: Screw air-cooled chiller(or heat) use Y-depressurization start mode. 
5. External air cooled oil cooling device: In order to ensure good lubricating oil lubrication, we use External air cooled oil cooling device to cool down the temperarure, Reduce the consumption of cooling capacity and Stable refrigeration system. 

6. Perfect protection function: Screw air-cooled chiller(or heat) have perfect protection function, such as power wrong phase lack protection, System high-voltage protection, System low voltage protection, Double antifreeze protection, Compressor overload protection, The insufficient frozen water cooling protection, Prevent frequent start protection, Compressor built-in exhaust temperature and coil overheat temperature protection and so on. 
7. Well separated frozen oil and refrigerants: In order to more fully the frozen oil and refrigerants separation, Low temperature cold water chiller external centrifugal efficient oil separator, it Can greatly reduce in low temperature and stranded in the evaporator of frozen in oil. 
8. Plus liquid spray technology: To further ensure compressor motor not overheat, Screw air-cooled chiller(or heat) use plus liquid spray technology, with low temperature cold media on the motor cooling directly. 
9. Automatic capacity adjustment: Screw air-cooled chiller(or heat) according to the use of air conditioning can automatically adjust load capacity. The standard chiller capacity adjustment method using segmented or non-polar uninstall way. 
*0. Green environmental protection: In order to better protect the atmosphere, it Can producte green environmental protection etc cooling medium refrigeration and air conditioning equipment not only in adopts HFC**7C and HFC**4A, but also in HCFC*2. 

*1. Balance run: Many of the chiller with compression, microcomputer automatic memory will be per compressor operation time, start the next time it will be activated running less time compressor. 
*2. Remote control: Each chiller with remote control function, the computer controller is equipped with RS**5 communication interface standards, open communication protocol, all kinds of building monitoring system connected even remote different ground monitoring. 
*3. Defrost: Accurate design aluminum pieces from the maximum to reduce frost probability. 
*4. Waste heat & secondary condensation: Rely on waste heat generated when the pump cooling system to take domestic hot water, without additional consumption of electricity, fuel; Almost zero cost; No pollution, no need to add other devices, just access to water pipeline, direct access to hot water. 
*5. Heat recovery chiller: In today \'s increasingly tense energy, waste heat use will have long-term economic value, on this basis, the Division I developed a heat recovery chiller can be full recovery of the original go condensing waste heat released into the environment.
