Mitsubishi Electronics PEH-7MYA, PE-8MYC Mechanical Specifications, Typical Installation Example

MECHANICAL SPECIFICATIONS

General

All units are factory assembled, piped, internally wired. They are also tested and checked under a strict quality control system in the factory.

Exterior surfaces of all units of outdoor unit are phosphatized, zinc-coated steel with powder coating and ivory white baked enamel finish.

Condenser Coils

Unnecessary power input due to higher discharge pressure is avoided by high performance designs of cross-finned coil.

Condenser coils are made of 9.52mm OD, 0.35mm thick seamless copper tubes mechanically bonded to 0.12mm thick aluminium fins and factory pressure and leak tested at 3.3MPa.

Refrigeration Controls

Refrigeration controls include condenser fan, evaporator fan and compressor contactors.

Compressors

All units have high efficiency type hermetic line starting compressors.

Compressors are equipped with thermal overload protector, over-current relay and high pressure protection control.

Crankcase heaters are standard.

Evaporator Fans

The sirocco fans are made of galvanised steel and balanced to proved accurate air flow performance at low noise level.

Condenser Fan

The direct-drive propeller fan is dynamically balanced, to ensure smooth airflow.

A weatherproof three-phase squirrel cage induction motor is used to drive the condenser fan.

Evaporator Coils

Highly efficient cross-finned coil are applied to provide a larger cooling capacity with low air speed on the coil. Coils are made of 9.52mm OD and 0.35mm thick seamless copper tubing mechanically bonded to 0.12mm thick aluminium fins and are factory leak tested at a pressure of 3.3MPa. They are provided with strainers attached to the capillary tubes to further ensure a clean system.
