DC Inverter Technology
An “inverter” is a power conversion circuit that electronically regulates the voltage, current and frequency of products such as air conditioners. This circuit controls the compressor and hence, the air conditioner’s output. Raising the frequency increases the output, whilst lowering the frequency reduces it. In this way, inverter air conditioners provide much finer temperature control than can conventional models.
Haier inverters provide a range of benefits over conventional start/stop systems. These include:
- Significantly lower running costs compared to conventional systems
- Rapid and efficient room temperature changes
- Elimination of temperature fluctuations associated with traditional start/stop systems
- Greatly reduced system noise both inside and outside the home
Inverter and Conventional Comparison
Apart from its significantly reduced running costs, inverter technology has two distinct comfort advantages over conventional air conditioners:
- Whether cooling or heating, it will reach the selected “Comfort Zone” quicker, as shown in the graph below.
- It can then maintain operating temperatures within the “Comfort Zone”, at all times, which conventional
air conditioners are unable to do – also as seen in the graph below

Haier's high efficiency compressor
Haier twin rotary compressors feature powerful neodymium magnets which are 10 times more powerful than conventional magnets. The result is:
- Higher energy efficiencies than conventional compressors
- Wider operating ranges
- Less vibration, resulting in quieter operation

Greater Energy Savings
Inverter systems deliver substantial energy savings compared to conventional start/stop systems, under normal operating conditions. By optimising energy consumption, not only will energy be saved, but CO2 emissions will also be reduced.

Greater Comfort
When an inverter air conditioner is switched on it supplies the exact power needed to heat or cool the room rapidly. This enables the air conditioner to reach the set temperature in around half the time required by conventional models.
Air conditioning noise levels inside and outside the home are dramatically reduced by Haier inverter systems because they always seek the lowest operating level, whilst providing the maximum heating or cooling effect.
