Top Discharge Condensing Unit （Inverter Series）
High-efficiency inverter compressor; high-efficiency PMSM; high-efficiency heat exchanger; 180°vector control technology
High-frequency operation and rapid cooling/heating
The DC inverter compressor will run cooling at the largest power input and largest airflow each time it is started until the set temperature is approached. Then, it runs at a low speed and low power input, which thus can not only keep the temperature from fluctuating but also avoid frequently starting and stopping the compressor so as to prolong its service life.
As for the DC inverter compressor with the permanent magnetic synchronous motor(PMSM), there is no current through the motor rotor, no eddy current loss and little heat produced, which means less ineffective power loss so that the motor’s efficiency can be improved and the power input can be reduced greatly.
Micro channel heat exchanger
Micro channel heat exchanger (MCHX) transfers heat through multiple flat fluid-filled tubes containing small channels, which can enhance heat transfer coefficient so that heat exchange efficiency is increased by 30% compared to the normal fined tube heat exchanger. (Note: For cooling only condensing unit)
Wide operation voltage range
The unit can safely operate within 187~254V.
180° vector control technology
With DC inverter 180° Vector Control Technology, compressor can run more smoothly. According to special analysis, harmonic wave of DC inverter compressor is smaller than that of common inverter compressor. With lesser heat output and higher energy efficiency, motor can help saving 20% energy per year.
According to customer’s needs, system output and operating frequency can realize stepless regulation within 10%~120% and 22Hz~80Hz respectively.
Special thickened inner groove copper tube enhances heat exchanging performance.
Hydrophilic blue fin
Highly anti-corrosion blue hydrophilic coated aluminum fin has long lifespan than common fin.
Flexible electronic expansion valve
The electronic expansion valve guarantees that the system makes adjustment automatically according to the changes of the circumstance and water temperature. It is more energy saving and stable than capillary.
The newly designed 4-side detachable case is capable of not only accommodating the large-sized electric box but also keeping a compact structure. The compact design of the indoor and outdoor unit helps to reduce the installation space and transportation cost.
