Specifications
Technology developed to ensure
high reliability
A high reliability is ensured with the new alternative refrigerant
model with the following means.
1.Increased compressor motor torque,
2.Increased withstand level of the refrigerant system
(piping, function parts),
3.Improvement of the high-pressure protection control, 4.Optimizing
of the heat exchanger sensor position, and 5.Incorporation of newly
developed compressor oil, etc.
Use of multiple compressors to increase
the operating frequency range
Two vertical scroll compressors are mounted in the
8 and 10hp (224 and 280 model), allowing fine energy saving
operation from 25Hz. Furthermore, by downsizing the inverter, the
generation of high frequencies is suppressed. If the non-inverter
compressor should fail, emergency operation is possible using only
the inverter compressor.
Outstanding low sound levels
with newly developed large fan
The newly developed 570mm diameter large fan, realizes low sound
levels of 59dB, the lowest in the industry. (Approx. 2db reduction
compared to current 10hp model.) The silent mode that allows the
operation sound to be reduced 2 to 3db is also available.
Heating operation up to an outdoor
temperature of -15C
Heating operation is also possible to an outdoor temperature of -
15C, so the unit can be used even in cold climates. Cooling
operation is also possible up to an outdoor temperature of -5C,
so cooling/heating can be carried out year-round.
130m long piping specifications
( custom order)
1.The level difference of the outdoor unit and indoor unit is
maximum of 50m, and an one way length of 100m is possible.
When custom orderd. one way length of up to 130m is possible,
making this the longest piping specification in the industry.
2.The piping length after the first branch has been extended up to
40m as a standard.
Improved installation and construction
performance with ultra-compact design
The 8 and 10hp (224 and 280) outdoor unit height has been
reduced from 1,700mm to 1, 450mm by changing the heat
exchanger to a rear panel single face heat exchanger. Now the size
of the multi-KX unit is the same as the MHI’s 8 to 15hp outdoor
unit (224 to 400) class for stores. The width of the 5hp (140) has
also been downsized.
Remote addressing with new controller
If the remote controller and indoor unit are connected one-on-one,
the address can be decided from the remote controller without
setting switches on the indoor PCB.
Demand control function
with high energy saving effect
The compressor is forcibly turned OFF by external signals to
correspond to peak cuts during the summer.
Indoor/outdoor connection unmatch
check function mounted
An indoor/outdoor unmatch check function that automatically
checks each module whether the
indoor/outdoor unit setting and piping system are correct during
the trial operation has been mounted.
