What's the magnetic suspended cold water unit
Magnetic suspension refrigeration is defined as the use of magnetic suspension technology in centrifugal cold water units, which reduces mechanical wear and tear and makes refrigeration more efficient and energy efficient. As can be seen from the structure, the different parts and the key to the magnetic suspended frequency centrifuges are the magnetic suspended centrifuge compressors, compared to the normal variant centrifuges。
Magnetic suspension system, which consists of rotors, sensors, controllers and components 4 of the implementer, consisting of both electromagnetic and power amplifiers. Magnetic suspension bearings are a lubrication system that is necessary to use magnetic fields to hold the rotor up, so that there is no mechanical contact during rotation, no mechanical friction, no need for mechanical bearings and mechanical bearings. Magnetically suspended cold water units use magnetic suspended bearings, using magnetic fields to levitate the rotors, rotate without mechanical contact with the leaves and without mechanical wear and tear and no need for mechanical bearings and corresponding lubrication systems。
What's the advantage of a magnetic hanger
The key to the advantage of magnetic suspended frequency centrifugal chillers over ordinary variable frequency centrifugal chillers is the magnetic suspended centrifuge compressor. The normal centrifuge compressor works through the traditional axle bearings, while the magnetic suspended centrifuge compressor works through the permanent magnetic generator, which makes the magnetic suspended centrifugal chiller an enormous advantage。
Energy efficiency: the peak efficiency of the aircraft is as high as 12 under partial load operating conditions. Operating throughout the year with general air conditioners, up to 35 per cent power savings compared to other cold water units
2. Low day maintenance costs: a magnetic suspended fleet system has few motor components, there are no complex oil route systems, oil filters for oil cooling systems, etc., no annual cleaning of the mainframe, only evaporation, condenser water treatment cleaning, evaporation condensers at a cost of 0. 1 to 0. 2 million at a time and save maintenance time to avoid inconvenience caused by peak cleaning units of refrigeration demand
3. Run noise and low vibration: the magnetic suspension team does not have mechanical frictions, has a gasket barrier, produces extremely low noise and vibrations, compressor noise is below 77db, and does not need shock cushions or spring shockers and soundproofing rooms。
4. No friction loss: no mechanical bearings and gears, no mechanical friction loss, no lubricating oil cycle, pure refrigerant compression cycle, no need for lubricating oil heating or cooling, only about 2 per cent of the loss of magnetic suspension bearings compared to the loss of traditional centrifugal bearings
5. Low start-up power: the utility of a conventional large screw unit is large, generating high shock currents at the moment of start-up, generally up to 200a-600a, with wave power grid stability, so that protection measures must be considered in grid design. The start-up process of the magnetic float group uses compressor-modified software to initiate electrical currents as low as only a negligible 6a, thus initiating small currents, low shocks to the grid, and no specific protective considerations for grid design。
6. High system sustainability: even if the oil contained in the conventional large screw group system is cleaned annually, the energy efficiency loss will be 25 per cent as a result of lubricating oil residuals and accumulation, leading to poor heat-replacement efficiency and heavy machine loads, but the effectiveness of cooling is poor and the longer the operation period, the less efficient, the more evident. There are no oil-free and no problems with lubricating oil residuals and controls, so there is no loss of efficiency caused by lubricating oil as the operational life increases。
7. The green fleet uses an environmentally friendly refrigerant r134a, a zero ozone layer loss value (odp), which is a positive-pressure refrigerant and avoids the risk of systems mixing into air。
8. Anti-gaspation: the compressor control module provides a control curve for the safe operation of compressors, allowing for real-time monitoring of the compressor's operational status, calculation of the proxies and timely adjustment of the rate to ensure that the compressor remains in a safe area。
Shortcomings of the magnetic suspended cooler:
Prior-period investments were relatively large and costly. There are many attachments, and individual types also need to expand water tanks and increase leakage points. The outdoors are large and heavy. Cold water machine
