Air cooled duct air conditioning

The indoor unit adopts a double-walled structure, with high-pressure foamed polyurethane sandwiched inside. The unit has a high structural strength. At the same time, it avoids the insulation of single-walled structure such as glass wool and blown glass fibers into the air-conditioning area. . The unit basically adopts the form of dual system or multi-system, with a maximum of 6 systems, which can realize multi-stage regulation of cooling capacity and reduce operating costs. The microcomputer controller can realize four functional modes of cooling, heating, ventilation and automatic, and has the functions of timing switch on and off, automatic detection, fault display alarm, automatic loading and unloading, and automatic defrost.
