Part 1 General information
1. MCCU introduction
Midea R407C MCCU (Compressor Condensing Unit) can be free connected with other indoor coils through a set
of connection accessories (supplied by factory).
There are 2 air discharge types, 7 sizes and totally 14 models for MCCU. They are designed to work in a wide
ambient temperature: 18~45 in cooling;℃-10~24 in heating, to adopt different kinds of applications and climate℃
environment.
Midea R407C MCCU is completely assembled, internally wired, charged with R407C refrigerant at the factory,
tested before shipment and ready for installation. They are widely applied in supermarkets, shopping malls, hotels,
airport waiting halls, and so on.
2. Features
2.1 Casing
Unit casing is constructed of heavy gauge galvanized steel plate. Both sides of the casing are waterproof and
anti-corrosion coated. Unit panel structure is allowed to maintenance on one side of the unit. Service panels are
removed easily and reinstalled by removing bolts. The unit is available for fork lifting transportation.
2.2 Compressor
Units are equipped with direct-drive, hermetic, scroll type compressor, and its build-in motor is cooled with suction
gas. The voltage utilization range is plus or minus 10% of unit nameplate voltage. The compressors, incorporating
a built-in muffler, are mounted on springs within a steel housing to give a low-noise level.
2.3 Heat-exchange coils
Inner-threaded and 9.52mm or 7.94mm copper tubes mechanically bonded to a configured hydrophilic aluminum
fin is standard for the heat-exchanger. Coils are leaked tested at 4.2MPa at the factory to ensure the pressure
integrity.
2.4 Fan
Fans are multi-blade vane-axial type, quiet operation and durability. It is directly driven by waterproof motor to
ensure reliable continuous operations. Statically and dynamically balanced drive motor design with
maintenance-free bearing for outdoor installation.
2.5 Three-phase protector
The unit with 3-phase power supply is equipped with phase sequence protector as standard. These devices
protect motors and compressors against problems caused by phase lack, phase imbalance and phase reversal
indication. When the voltage is above or below the normal range, it works and prevents units from suffering
voltage fluctuations.
2.6 Controls
Units are completely factory-wired with necessary controls and wiring terminals for power wiring. Microprocessor
controls the cooling, heating and ventilating modes in response to signals from sensors measuring indoor and
outdoor temperatures.
