1.4Products characteristic
(2).HFC refrigerant technology
To protect the environment, we have adopted the HFC refrigerant. The HFC R407C is of zero ODP
for the purpose of environmental protection.
(3).Ceiling/console convertible,flexible installation,convenient maintenance,saving
the users' expenditures
(4).Adopting single-phase or three-phase power supply,applicable for household
and commercial usage
(5).Dual air outlet design,floor air blowing,accelerating the indoor air circulation,
quick temperature adjustment
(6).Long-distance air blowing,large power,large cooling/heating ratio
(7).Intelligent remote control,convenient and flexible control
(8).Super-slim indoor unit design,luxury and nice-looking,saving space,harmonious
and unitive with the indoor environment
(9).Adopting screw-fastening for the air inlet grill,firmly fixed;adopting slipway
insert-lock fastening method for the filter screen,convenient cleaning or replacing
the filter screen without opening the air inlet grill.
.
The system can run the cooling operation at the low ambient temperature -15
(1).Low ambient temperature cooling technology
(10).Group control,units up to 128 sets can be controlled
