Air cooled magnetic bearing centrifugal chiller factories

Air cooled magnetic bearing centrifugal chiller factories

Introduction:

Product Description：
Air cooled magnetic bearing chiller: Adopts high-integration single-chip microcomputer which greatly improves the anti-interference ability of the system. The HMI directly displays the fault content, and cooperates with the simple operation interface to timely feedback various maintenance information.
The unit control system can be connected to the user's central control system(BMS)so the customer can monitor the chiller operation at any time.
Over-voltage,under-voltage, three-phase unbalance,and lack- phase protection are applied to the power supply system. And the chiller has built in more than 30 protection functions to provide comprehensive protection for the safe operation of the unit.
The chiller from H.Stars magnetic chiller factories has advanced multi-anti-surge function, which combines prevention, control and alarm to ensure the unit meet the customer's cooling capacity within the safe operation range. Reserve user connection points to provide cloud services.

Customized Design
Controller interface
Magnetic bearing chiller : Adopts 10 inch touch screen, the display with a larger screen and true color quality is more delicate and clear for operators to use.
The operation screen is simple and exquisite,showing a lot of useful information and easy to operate.
And it's designed with USB interface,easy to upgrade or download the chiller history running data chart.

Main Components(Shell and Tube Heat Exchanger)
Magnetic Oil Free Centrifugal Chiller
High efficiency evaporator
The refrigerant entering the evaporator is spraying downward from the upper side of the heat exchange tube array and the liquid refrigerant forms a film flowing downward on the tube wall. Since only a layer of liquid refrigerant film is coated on the surface of the heat exchange tube,the heat transfer effect is excellent.
The shell is made ofQ345R steel, the heat exchange copper tube is double-sided enhanced high-efficiency tube.and besides the heat exchange tube is available in various materials and thicknesses.The distributor is made of stainless steel and is produced by self-owned CNC machine to ensure the quality of liquid distributor structure of falling film evaporator.
It only needs a small amount of liquid refrigerant at the bottom of evaporator,so the refrigerant charge volume of the unit is small and meets environmental protection requirements.
The refrigerant vapor does not need to be superheated,and the evaporation temperature can be greatly improved.

High efficiency condenser
The shell is made of Q345R steel,and the heat exchange copper tube is double-sided enhanced high-efficiency tube.which is used to condense the high-temperature and high-pressure refrigerant in the refrigeration system into liquid.with certain degree of sub- cooling.as a result the chiller unit can operate efficiently and energy-efficiently.
The built-in liquid refrigerant separation device ensures that the liquid refrigerant after condensation is automatically separated from the heat exchange tube.ensuring sufficient contact between the heat exchange tube and the gaseous refrigerant and greatly improving the heat exchange efficiency of the copper tube For large capacity chiller units,this technology is very effective reducing the condensation temperature by about 1C.

Economizer
Flash evaporator: The shell is made of Q345R steel. It uses the evaporation of the refrigerant of the unit to cool the liquid refrigerant after the condenser is condensed,which increases the effect of sub-cooling and makes the unit run more efficient and energy-saving.
Plate Type Economizer:SUS316L stainless steel.The Economizer adopts a small portion of the refrigerant evaporated by the expansion value after throttling, and together with the main refrigerant to be exchanged heat through the plate to reduce the temperature of the main refrigerant, there by to increase the effect of sub-cooling to improve its energy efficient.

Heat Recovery Unit
Air cooled magnetic bearing chiller:Heat recovery technology is to recycle part of or all of the heat capacity produced during the refrigeration process by heat recovery unit,magnetic chiller supplier to provide customers free hot water from 45℃ to 55℃suitable for hotels hospitals,schools and other places of large public institutions. Green to environment and energy saving.
