2. Product character
a. Installation conveniently, no need the special machine room and water tower; can be installed on the
roof or out of the room. Widely application for cinema, hospital, hotel, school, commercial building, etc.
b. Utilize flexible scroll compressor. And adopts dual compressors in parallel technology. The master unit
will control both compressors run or stop due to the water outlet temp. Optimum refrigerant distribution
technique and minimum-deformation design. Adoption of rolling bearing and non-lubricated bearing.
Excellent heating effect at low temperature. Broad range of working temperature and suitability for high
c. Shell & Tube and U type inner grooved finned coil heat exchanger.
High efficient water side heat exchanger: in cooling, the water side heat exchanger is as evaporator; in
heating, it is as condenser. The freezed water flows outside of the pipe, and the refrigerant flows in the
pipe. Optimum design, reliable operation, reasonable structure, perfect performance.
d. Central control technology, indoor unit be connected with controller by dual core non-polar wire. The
indoor units can be controlled individually or simultaneously, more convenient, more energy saving.
One central air conditioning system can include max. 8 sets (65 series) or 16 sets (100 series) of
module unit. Through the dip switch on PCB you can set unit No. of every module unit, and every unit is
connected by RS485 port. Compact structure, convenient for electric installation.
e. Fan coil simultaneous control technology: indoor fan coil can be controlled individually or centrally.
