HBW Water cooled screw chiller

الوصف

1.Precise stable water temperature
As used for industrial cooling, Low temperature water which produced by warter-cooled chiller could send to the equipment and containers directly which need to be cooling.But in order to control precise stable water temperature,the water comes out of the chiller send to the Buffer pool firstly,then entrance the equipment or containers which need cooling.
2.Y-â–³depressurization start mode
Half a dense screw water chiller use Y-â–³depressurization start mode. The starting current is only about 1.5 to 2 times about run-time. Greatly reduce the impact of the grid
3.Capacity adjustment
Screw water-cooled chiller according to the use of Client load can automatically adjust load capacity. The standard chiller capacity adjustment method using segmented or non-polar uninstall way. Single machine can realize the four sections of compressor capacity **0%**5%**0%**5%.And *5% of them used for compressor start. Also can be *5 to **0% of the induction capacity control , but in order to ensure the safety of long-term operation of the chiller , not the long - term applied to the extremely harsh environment of the place and run a long time in less than *0% of the nominal cooling capacity of chiller , the ordering period , please indicate the use of conditions
4.Perfect protection function
Screw water-cooled chiller 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. Reduce losses caused by all kinds of accidents happen.
5.Meet the temperature requirements of various industries
Screw chillers in the use of industrial cooling can be applied to a variety of cryogenic cooling , add the appropriate antifreeze in the chilled water side can be achieved 0C to - *5C the water temperature to suit different industrial cooling requirements , usually antifreeze, solvents , ethylene glycol, sodium chloride and calcium chloride solution , recommends that customers in the application of different concentrations of antifreeze solution set according to water temperature , the freezing point of a variety of solutions please refer to the installation and use "section
6.Higher cooling energy efficiency
As the use of central air conditioning with air - conditioned boxes, fan coil and secondary heat exchanger used in conjunction with , cooling energy efficiency ratio is the biggest advantage of the water-cooled chillers. In standard conditions ,screw water-cooled chiller COP is typically 4.6 to 5.0 ,energy efficient, substantial cost savings for the customer's use .
7.External water-cooled plate oil cooling device
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.To ensure that the compressor lubrication system security.At the same time also improves the heat transfer effect of the evaporator.
In order to reduce the lubricating oil overheating due to the low temperature is too high exhaust temperature , low temperature chiller using an external water-cooled plate oil cooling device by the temperature of cooling water , cooling lubricants, not only to reduce the consumption of the cooling capacity , but also stable cooling systems.
8.Plus liquid spray technology
To further ensure compressor motor not overheat, Screw water-cooled chiller use plus liquid spray technology, With low temperature cold media on the motor cooling directly.To ensure the long-term and stable operation of the compressor.
9.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.
*0.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.Similar in the discharge of the need, but also will be preferential the operation longer time to uninstall chiller, in order to achieve the balance of each compressor operation, extend the service life of the machine.
*1.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.
*2.Cold water chiller recyclable
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 , used in hotels , dormitories , toiletries and other occasions ; such as heat recovery technical parameters, please contact our technical department to obtain.
*3.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
    Due to secondary condensing, can appreciably reduce condensate temperature and pressure, and, to some extent, can also raise the efficiency of refrigeration.
*4.Compressor & major refrigeration original
Twin-screw compressor, compressor selection is the world's most advanced fourth-generation asymmetric patent tooth rotor , processing by the British HOLROYD rotor machining , grinding precision machining by the German KLINGELNBERG precision rotor grinding machine , greatly reducing leakage and cooling loss ; the use of advanced three - stage oil network , making the oil filter up to *9.7% , which greatly limits to ensure the oil return compressor , compression built-in wide range of protection to ensure that the compressor safe operation of the running , small vibration , low noise , high efficiency.
    In addition to the compressor refrigeration components are imported quality products, such as the expansion valve , solenoid valve , filter drier , etc. European and American quality products , reliable performance and precise control .
*5.Touch screen type human-computer interface
Microcomputer controller controls all imported from Germany Siemens PLC controller , accurate and intelligent , and truly achieve perfect control of the machine , thus ensuring the safe operation of the unit , and achieve the purpose of effective energy conservation , the use of touch-screen human-machine interface , the use of simple and friendly interface
*6.Test center
