Neighbour-friendly quiet outdoor unit

The adoption of the Night Quiet for the inverter outdoor unit reducing speed of the ccompressor and the fan in the summer night time of less load, and the low noise ccompressor achieves the front rank quietness.

Neighbour-friendly quiet design.
And Night Quiet is added !

Automatic sound suppression at night* is automatically set with the change in outdoor temperature. To change the system to quiet operation mode according to the operating time zone, connect a timer to the external contact point and set desirable time. Either mode of "Auto" or "External input" is selectable.

* : The nighttime automatic quiet function is available in setting at site.

Compact

Super aero grille and hybrid aerofoil fan contribute to space savings.

With a coil shaped grille rib that matches the fan discharge direction, the spreading of air in that direction is reduced and short circuits are alleviated. This also achieves space savings.

Durability

As the bottom frame is subject to corrosion, corrosion-proof galvarium steel plate is adopted to enhance the durability.

Heat exchange fins provided with anti-corrosion treatment.

The outdoor unit's heat exchanger fin has been specially pretreated with an acrylic PE coating to improve their resistance to salt corrosion and atmospheric pollution.

Powerful

Defrost control achieves powerful heating in very cold climates

To optimize heating performance, temperature differences between the air in the indoor/outdoor heat exchanger and the intake air are monitored and accurate adjustments made to provide the best operating parameters, such as activating the defrost mode and minimizing indoor temperature drops caused by frost. For example, if the outdoor temperature falls to -1.5属C, the integral heating capacity is raised about 20%.

Fuzzy logic controller realises energy efficiency and comfort

As operating conditions change, fuzzy logic precisely controls actuation of the electronic expansion valve.

Easy installation and maintenance

Pre-charged for up to 30meters

If refrigerant piping length does not exceed 30 m, there is no need for on-site gas charging.

70 m piping length

Easy centralized installation with the module oriented design

Depth of P71D to P125D are standardized as 320 mm. Horizontal continuous mounting is available.

4-direction piping affords more freedom of layout

The outer panel for the piping connection part of the front, right side and backside can be removed and is easier for post-installation piping work.

Low gas level detection function

Effective gas monitoring reduces the labour required for operation, maintenance, and repairs.

 

Energy savings

10% less outdoor unit standby power

In order to prevent refrigerant from collecting in the ccompressor, air-conditioner outdoor units employ approximately 30 Watts of power for the crankcase heater when the air-conditioner is not running. This standby power has been reduced to make outdoor units more Energy savings.

Safety

Reinforcing wire fittings (option) are available

Fittings can be mounted on the four locations, right/ left on front and back side of the outdoor unit.
