Single-stage air conditioners utilize the following principle: once it is launched, the compressor starts working at full capacity right away. Once the temperature indicator signals that the appropriate temperature has been reached, the air conditioner will switch off automatically. Once the temperature goes up a few degrees, the single-stage air conditioner will start working again. It will continue to switch itself off and on during the day. Such inconsistent work can cause peak loads, dramatic temperature fluctuations and noise (especially during sleep hours). Because the compressor in a single-stage air conditioner is turned on and off several times during a day, it consumes a lot of energy. A heavy workload such as this, compressors get damaged and can hardly be repaired. Please, choose an air conditioner with a longer warranty.
How Do Two Stage Air Conditioners Work
Two-stage air conditioners feature microchips. They check ambient temperature and automatically set the compressor to operate in an energy-efficient mode. Unlike their single-stage counterparts, two-stage ones can change the number of revolutions per minute (RPM) if necessary. Instead of switching it off completely, the microchip will just reduce RPM and switch the device to an energy-efficient standby mode. Two-stage air conditioners operate at low RPM, consume a smaller amount of energy, maintain optimal temperature, and make little noise. This mode guarantees reliable and continuous operation.
− It takes three times less time to cool down a room.
− Energy consumption is reduced by 30%.
− No power on/off cycles and therefore no peak loads.
− Minimal temperature fluctuations.
− Quieter operation due to lower RPM.
− All 2 stage air conditioners can operate in a heat pump mode and can be an additional source of heat during cold seasons. Also, they can dry air and prevent mildew.
