1. Features
DC Inverter Twin Rotary Compressor
1) Realize high efficiency and compact designed compressor
by joint wrap & earths metal magnet motor.
2) Wide range inverter compressors would satisfy the
customer's innovative requirement and design.
DC Inverter Motor
DC fan motor speed can be adjusted from 0~1000 r/min, it
can improve the unit efficiency, at the same time, the unit can
realize low ambient cooling operation.
High efficiency
Low vibration, low noise
High reliability
Precise Control
PID control adjusts the output of compressor and the open degree of EEV, balances the indoor refrigerant flow,
realizes the linear output, creates a comfortable environment. The temperature could be controlled precisely.
