Advanced oil system
Electrical control
Adoption of the special oil separation and return system, built-in oil separator, ensure the systems' stability.The lubrication system can heat oil to match the chillers exact requirements, guaranteeing the system is always protected against unnecessary wear.
Midea intelligent controller
User-friendly operating interface
Midea water cooled screw chiller adopts a Microprocessor controller which enables the user to monitor and control the chiller with precise accuracy. The Microprocessor control system guarantees high precision and stability. The module-designed control system is easy for installation and maintenance. The chiller comes with a reserved RS485 port which can be interfaced with BAS (Building Automation system). Remote monitoring and control of the chiller is possible.
Complete and safe control system: The unit is designed with multiple security measures to ensure safety and reliability. All sensors and safety features are assembled, equipped and undergo strict testing in factory. Touchscreen display: Color coded, easy for operation. Three status indicators on the screen clearly indicate power, system status and communication
True color touchscreen
Intelligent control By monitoring all parameters, the intelligent control logic decides the best load adjustment method, it optimizes the EXV and the capacity slider to guarantee safe operation under various load conditions. Conventional BMS systems only focus on the interlock control, operation status and parameter monitoring, which achieves automation and energy management,but fails to realize the benefits of equipment synchronization. Midea centralized energy management system attaches importance to building load prediction and control, and coordinates the operation of air-conditioner, fan and water pumps to realize optimum energy management.
Control regulations,operating parameters, diagnostics reports, and error messages are all displayed on a 7 inch, 65636 colors TFT screen with 800×480 resolution. The screen also displays error codes, various settings, specified temperature and pressure values, the status of operating parameters and options.
Weekly operation scheduling The user can set the chiller operation schedule on the weekly timetable to run and stop the chiller automatically. If an unscheduled shutdown occurs, the chiller will not restart unless manually reset.

Note: 1.Customer to specify the exact nominal power supply available on site so that correct electrical components are selected. 2.Main power must be supplied from a single field supplied and mounted fused circuit breaker. 3.The compressor crankcase heaters must be energized for hours before the unit is initially started or after a prolonged power disconnection. 4.All field wiring must be in accordance with local standards. 5.Neutral line required on 380V-3Ph-50Hz(5 wires) power supply. 6.Rated load amperage values are nominal conditions. 7.A ±10% voltage variation from the nominal conditions is allowed temporarily only,not permanently.

R22 DX (255 to 970kW)
Features and benefits Technologically advanced twin screw compressor Midea screw chiller is equipped with the 3rd generation industrial compressor that has the latest advanced 5-6 asymmetry dentiform Semi-hermetic Screw Rotors. The rotors are tooled by high-precision CNC mills with each part being precisely sized and aligned,minimizing friction and clearance loss as well as guaranteeing low noise levels and durability.
R22 DX (255 to 970kW)
High efficiency, energy saving Extremely high full load and partial load energy efficiency. New twin-rotor screw compressor equipped with a high-efficiency motor and a variable capacity valve that can adjust capacity in 4 stages 25%, 50%, 75% and 100% (Stepless control is optional) allowing the cooling capacity to more accurately match the actual load. A decrease in chiller energy costs, particularly under the partial-load conditions at which the chiller operates most of the time.
Outstanding reliability Full factory testing of the unit, including water hookup to simulate real conditions, helps provides a trouble-free start-up. Extensive quality control checks during testing means that all equipment protection features and operating controls are properly adjusted and operate correctly before leaving the factory. Equipment must also pass a transport simulation test in the laboratory on a vibrating table. Factory-installed options minimize field expenses and installation labor costs.
Easy and fast installation The unit passes full factory test before being delivered to ensure reliability on site. The unit can be in service after simply being connected with power and water supply. Installation and adjustments are made simple by standard flange connection and wire mesh to the electrical panel. Refrigerant and lubrication oil are installed in factory. Only piping and power supply need to be hooked up on site.
Intelligent control, easy operation Microprocessor control comes standard on all units. A display illustrates the machine’ s operation status and programmable parameters (set points) e.g. water temperature and refrigeration pressure and temperature, allowing the operator to determine the unit status and also make changes to various set points. The control use a PCB with predictive logic to select the most energy efficient combination of compressors. 21
