Modular design concept makes the application from single unit to multiple form systems to several thousand tons of installed capacity.dopting high reliable and excellent efficiency system Midea air cooled scroll become one of the best choice for all kinds of air cooled projects. With the latest modular design technology, high efficiency V shape heat exchanger and precise gas flow control technology and digital compressor application, Midea air cooled scroll chiller system always work at the most high efficiency stage. Modular and compressor operation are adjusted by the real load requirement intelligently to keep the most economical working status.

5 7 R4 (5-5) 5z R4 (5-5) 5z MODULR DESIN Midea air cooled modular chiller is designed to four basic modules. The modules can be field-coupled to meet large project tonnage requirements. The modular design also accoodates future expansions by allowing modules to be added in stages, to precisely match the expanded cooling requirements. Modular design provides excellent partial load efficiency. It provides big cost saving in shipping, transportation, lifting and installation. It also provides the possibility to stock in the distributor side for fast delivery. Strong backup make the system safe all the time Every module with independent system and modular system provide redundant back up in module itself as well as the modular system. In the event of a malfunction in one module, the adjacent available standby module will provide back up. One failed module will not disrupt the other chillers or system. In the modular system the Master units and Slave units can be setting easily for service or emergency treatment. Strong back up for system is showing as follow: When unit is failure If one slave unit fails, failure unit will stop but the others will keep running If master unit fails, all the units will stop but any of the slave one can be set as the master unit by manual setting in a very short time. When unit is under protection If master unit s protection occurs, protected unit will stop but the others will keep running. If slave unit s protection occurs, protected unit will stop but the others will keep running.

In the digital scroll compressor the controlled separation of the scrolls is achieved using a solenoid valve and a bypass connection between the discharge chamber and the intake gas. The scrolls are designed so that the upper scroll can separate from the bottom scroll by vertically. piston is attached on top of the upper scroll and will lift up the upper scroll when it moves up. When the solenoid valve is closed, the Digital Scroll operates as a normal Scroll compressor and the compressed gas is discharged at high pressure through the normal piping. When the solenoid valve is opened, the discharge chamber and intake gas pressure becomes connected, thereby releasing some of the discharge pressure. This leads to less pressure holding the piston down thereby causing the piston to shift upwards, which in turn lifts the upper scroll. Once the Scrolls separate, any gas passing through is no longer compressed. With the digital scroll technology the widest capacity adjustment rang can be achieved and the reliability of the compressor, comfort of the room temperature, efficiency of the whole system can be improved significantly. In order to gain the most precise and intelligent capacity output Midea air cooled scroll adopt the digital scroll compressor in small module of 5//65. It is one of the advanced technical advantages in air cooled modular product. Master Slave Modular system leads a excellent IPLV Loaded S S 5S 5S In a single chiller system the output capacity is proportional to the load of the building. In the partial load condition the single chiller system will operate at % to 7% which is a very low efficiency for a system and lead to a very low IPLV/NPLV. In a multiple system the system output capacity is not proportion to the load of the building and only one chiller will operate in the low efficiency area and other chiller will work in the high efficiency area. The IPLV/NPLV will be increased significantly by the modular design. Unloaded S S 5S 5S S cycle S cycle S cycle S cycle % output 5% output

The address is the main unit, other address are auxiliary units. ardware composing Computer, RS45-3 converter, KJR-/E,KJR-/ME wired controller, Module unit group.

The Chiller Controller continuously performs important self-diagnostic checks while monitoring system temperatures, pressures and protection devices. It wills automatically shut down a compressor, a refrigerant circuit or the entire unit if a fault occurs. Use the check button and LED display can check the system operating status. When under protection or error,the LED will display protection code or error code.

Differential pressure and paddle type flow switches are also provided with the units. The wired controller provides accurate water temperature control in the circuit by closely monitoring and reacting to the input from the water entering temperature, water leaving temperature and ambient air temperature. During normal condition, if the outlet water temperature falls below setting temperature (antifreeze temperature) the unit will be cut off automatically. low switch and contactor with thermal relays for compressor, fan motor and water pump are providing secondary protection for the unit. Each module is equipped with overload condenser fan motor protection and pump interlock input. 4 E3 Error of total outlet water.temp sensor(e valid for main unit) 9 P3 Low pressure protection System (manual recovery) 5 E4 Error of unit outlet water.temp sensor P4 Current protection in system (manual recovery) 6 E5 Pipe temperature sensor in condenser error P5 Current protection in system (manual recovery) 7 E6 Pipe temperature sensor in condenser error P6 Condenser high temperature protection in system E7 Outdoor ambient temperature sensor error 3 P7 Condenser high temperature protection in system 9 E Output of the power protector error 4 P (Reserved failure code) E9 Water flow detection error(manual recovery) 5 P9 Protection of outlet and inlet water temperature difference E (Reserved failure code) 6 P Low ambient temperature drive-up protection Eb reeze-proof temperature sensor in shell and tube exchanger error 7 Pb System anti-frozen protection 3 4 EC Ed Wire control detect that the units on-line have decreased.
