Efficient inner wall of sound absorption, insulation materials, achieve quiet operation. Compressor with double shock design to optimize the cushioning structure, reducing the noise. 

Compressor in a more favorable working environment, a longer life expectancy than air-cooled machine. 

Advanced microcomputer intelligent control, wired remote control (digital type, LCD type), the remote control can achieve independently of each air-conditioned room is simple stand-alone operation, precise control to ensure the comfort of the room. 

Use of Soil renewable natural energy, simply start the air conditioning units running circulating pump, energy efficient. 

System equipment is simple, easy to install, startup, easy to adjust, partition design flexibility. 

Depending on the season or the user needs to select the actual cooling or heating, partial heating or cooling section, and the thermal efficiency of the system is not affected by the outdoor temperature.
