R410a DC Inverter 60Hz

1. Features

1.1 High efficiency
V4+ S Series achieves the industry's top class energy efficiency of cooling and heating by utilizing all DC
inverter compressors, all DC fan motors and high performance heat exchanger. All DC inverter compressors
contribute to higher IPLV greatly. The highest IPLV is up to 5.8.
1.1.1 High efficiency DC inverter compressor
8HP&10HP units adopt one DC inverter compressor only. 12, 14, 16, 18*HP adopt two DC inverter
compressors. With all DC inverter compressors, V4+ S Series offers a wide operation range from 20Hz to
200Hz.
Powerful magnets provide high torque and efficiency and achieve 70% reduction in volume.
The A/C load ratio of building is 30%-75%, the area use ratio is 55%, most of the A/C runs in the mid load,
so the mid load operation ratio determines the whole year AC running charge.
Centralizing winding
Smooth sine wave DC inverter
Adopting the 180° sine wave inverter to smooth motor rotation greatly improves operating efficiency
compared with traditional sawtooth wave.
Common sawtooth wave
1.1.2 High efficiency DC fan motor, saving power 50%
According to the running load and system pressure, the system controls the speed of DC fan to achieve the
minimum energy consumption and best performance. All DC fan motors save much power consumption.
