Engineering >> Industrial & Management SystemsTemperature setting in an inverter air conditionerby Fritz Hegenbarth
Submitted : Fall 2017 Air conditioners have become a common factor in our daily life, human beings feel more comfortable in a temperature between 22°C and 25°C, and a relative humidity between 50% - 60%. Therefore, in order to live and work comfortably we require to install air conditioners capable to maintain these parameters. Air conditioner manufacturers have aimed their focus in creating new technologies in order to reduce the energy consumption of these equipment, and they have created what is called an inverter compressor, which by an electronic mother board, rectifiers and transformers they transform AC power into DC power, making the compressor able to oscillate between 20 to 75 Hz, instead of working at a constant 60 Hz cycle. Due to this energy improvement device, the inside temperature has become more stable, since the velocity of the compressor can be modified automatically by the electronic mother board, and maintaining the set point temperature almost stable, with a ±0.5°C difference from the desired temperature.
To be able to make the inverter more energy efficient it starts slowly and increase constantly until it reaches its peak power to reach the desired temperature. When it gets near the setpoint it starts to decelerate but it will pass the desired temperature so the AC unit starts to increase and decrease until the difference in temperature is very small. This way the air conditioner is save more energy instead of using its peak power at various times. Related Links:
