Water-cooling centrifugal chiller

Product Description

Centrifugal chiller is high efficiency and high reliability as the main appeal, combined with han clock C series double period of McQuay the most advanced centrifugal compressor and spraying evaporator consists of the cold media system, introduced the current domestic highest efficiency C series of centrifugal chiller. Efficiency.models acailable coverage for **0 to ***0 cold tons. The Taiwan industrial technology research and national testing center of hefei test, as high as 6.2, in line with the state COP GB**********4 primary energy efficiency standards. The central air conditioning unit in the application system and industrial process cooling.
1. Compressor
(1) the rigid ball bearings, low consumption of lubricating oil and can withstand frequent rev. Stop.
(2) close partly motor, with liquid refrigerant cooling, work safety and efficiency, constant temperature.
(3) the built-in oil separator, gear box of the compressor will be cast to minimize the amount of oil.
(4) the built-in immersed type oil pump, high reliability, and support the stable operation of the compressor.
2. Spraying evaporator
The spraying (falling film type) design, cold media recycling technology, cold media filling quantity, will be low oil liquid concentrated focus on a specific area, make back oil system to work smoothly.
3. Comer microcomputer controller
(1) the CPU core components, with executive 1 K WORDS program only 0.*5 ms computational speed, *2 inch touch screen take *2 M storage space, full display unit state.
(2) PD control function, according to the cold water temperature of output and target temperature difference value is automatically adjust the unit load, make water temperature in the shortest possible time to needs, and water temperature stability in the target temperature within + /*0.*0 C.
(3) unit protection function, have turned on in the operation of self ability before, with as many as *0 other protection function.
(4) breakdown processing function, can automatically recognize fault, instructions, and fault point in written form explained and, as soon as possible for users to provide convenient, automatic processing fault fault record.
(5) reserved users access points, obligate auxiliary equipment control points, unit output alarm point, remote control and the control points, stop the central monitoring communications points.
4. Product features
(1) unit use McQuay cold media. HFC working medium, as is McQuay international recognized environmental protection cold media, no use fixed number of year restrictions.
(2) units built-in oil cooler, cold media cooling, no maintenance.
(3) use of independent return oil system (jet pump is return oil), any load cases are to ensure timely return oil.
(4) in the subsurface pump unit was built in the oil, the oil pump compressor threat without leakage.
(5) unit with fixed orifice plate the throttle device, no moving parts, in the variable load and variable condition can adjust cold media flow, no lag phenomenon, ensure that the unit operation is stable.
(6) low voltage unit, use soft start ark step-down start, the starting up process won't impact the grid. Use party
(7) high voltage units, and the high voltage start ark, midterm configuration comprehensive protector, covers plugging turn, phase lack, over electric current, over voltage etc. Function.
(8) unit microcomputer control system using all Chinese, clearly show the pictures run data, the operation is convenient.
