Product introductionAir cooled modular chiller is a kind of central air-conditioning unit which adopts air as the cooling or (Heating) source and water as the cooling or (heating) medium to cool down or (heat ) the indoor ambient temperature through the indoor terminal(AHU/FCU). Air cooled chiller typically have a lower initial investment and maintenance cost than water cooled system since it does not require a cooling tower, condenser water pump, and associated condenser water chemical treatment system. Modular design concept makes the application from single unit to multiple form systems to several thousand tons of installed capacity.Adopting 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. They are widely applied in school, hospital, shopping mall, office as well as the factory and manufacturing processing area.

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 accommodates 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.
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 10% to 70% 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.
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:
If one slave unit fails, failure unit will stop but the others will keep runningIf 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.
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.
A scroll is an involute spiral which generates a series of crescent-shaped gas pockets between the two members( fixed scroll and orbiting scroll). 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 1mmvertically. A 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 25/30/65kW. It is one of the advanced technical advantages in air cooled modular product.

All Midea air cooled chillers are factory run-tested to confirm proper operation. Units are checked on a computer-based test stand at typical ambient and water conditions and control operation is monitored. Units ship with a full operating charge of Zero Ozone Depletion Potential refrigerant R410A and oil. Compressors, heat exchangers, condenser fans, piping, and controls shall be mounted on a heavy-gauge steel frame. Electrical controls, contactors, and relays for each module shall be mounted within that module. Exposed steel surfaces shall be provided with a powder-coat paint finish. The module is provided with a heavy-gauge, galvanized steel power coated enclosure suitable for outdoor installation.
Midea Modular Air Cooled Chillers are equipped with highly efficient Scroll compressors. These rugged hermetic compressors are constructed with an integral cast iron frame, cast iron scrolls, three Teflon impregnated bearings, and three oil filtration devices for each compressor. The orbiting scrolls only touch with enough force to create a seal. There is no wear between the scroll plates. The fixed and orbiting scrolls are made of high strength cast iron which results in less thermal distortion, less leakage, and higher efficiencies. Compressor-crankcase heaters are also included for extra protection against liquid migration.As a design requirement, this compressor characteristically offers extremely smooth performance, efficiency and operational reliability. Each compressor is mounted in the unit with vibration isolation, with oil sump heating and fitted with a heat overload cut-out.
The air cooled condenser coils with V-shaped consist of staggered rows of 3/8" OD seamless copper tube, mechanically expanded onto die formed aluminum fins to ensure optimum heat exchange capability. Condensers are factory leak tested with air underwater at 2.9Mpa air pressure.

All the protection and alarm information will be showed on the LED display on the main board. 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 .
Low pressure switch High pressure switch Three phase power protector
Midea modular air cooled chillers are equipped with intelligently designed safety control to ensure continuous
safe operation. High and low pressure switch is provided to prevent the compressor damage resulting from
either abnormally high discharge head pressure or low pressure. 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. Flow switch and Power
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.
