Features
Higher Energy Savings
The compressor in McQuay DC Multi Split Inverter is programmed to run at the optimum speed. The
compressor speed is controlled by input frequency that varies according to the indoor load requirements.
Once the indoor set temperature is achieved, the input frequency supply to the compressor will be reduced.
Hence, less energy is required to maintain the unit operation and this will consume less energy.
Fast Cooling
During the unit start up, the inverter air-conditioner system takes a shorter period to achieve the set room
temperature than conventional air-conditioner systems. Thus, the inverter system offers fast cooling features.
Low Starting Current
Taking advantage of the ability to modulate the compressor speed, inverter models are designed with “soft
starter” feature. The compressor motor will not draw high current during start up.
Zero-Ozone Depleting Potential Refrigerant
Introducing the new type of refrigerant – R410A which is environmental friendly with Zero Ozone Depletion
Potential (ODP = 0). R410A also provides the higher volumetric capacity and better refrigerating effect per
unit of volume.
Advance Technology
The traditional conventional air conditioners repeat “the start” and “the stop” during the thermostat cycle off
and causes the room temperature to be unstable. Incorporating fuzzy logic control into the McQuay DC Multi
Split Inverter design enables greater flexibility in handling the system control.
This result in:
•
Powerful, efficient and economical operation.
•
Even room temperature control.
•
Constant and quiet compressor operation.
•
Enhanced system reliability and reduced maintenance costs.
Low Noise Operation
McQuay DC Multi Split Inverter System has been designed to use the state-of-the-art, twin rotary compressor.
In this compressor, the roller phases are staggered 180° apart from each other. With this design, the centrifugal
forces of one roller is counterbalanced by the force of the other roller, whereby reducing the vibration of the
compressor. This makes the unit quieter and less vibration.
To further reduce the noise level, brushless DC motor is used. This further reduces noise generated by the
fan motor. Additionally, by using a bigger sized fan blade, a lower rpm is possible while maintaining ample
airflow.
Improved Compressor Life Span
For the McQuay DC Multi Split Inverter system, once the unit is started, the compressor rotation speed is
steadily ramp up or down based on load requirement throughout the operation. This control method gives
the compressor motor a smooth operation. It helps to reduce the wear and tear of the compressor motor. In
the long run, the life span of compressor is increased.
