Which are the Most Sustainable Air Conditioners?

Sustainable-Air-ConditionerThe inverter air conditioner is one of the most sustainable air conditioning units available because inverter technology is eco friendly technology and reduces the running costs by around 30%. It is the ability to vary the speed of the unit that lowers the consumption of electricity.  According to air conditioning experts Holdens Electrical, the inverter models stay on all the time and simply vary the running speed once the selected temperature is maintained. This means they not only use less power, but are much quieter too.By comparison, a non-inverter air con simply runs at the same start up speed all the time, switching on and off constantly to maintain the temperature. It is the constant starting up that gobbles up power and creates noise. If you are using an older model air con, it may not be an inverter type.Another way the inverter air cons are eco friendly is in the type of refrigerant used. This is R410a refrigerant, containing HFC, as against the R22 refrigerant that contains HCFC, a chlorine component known to destroy the ozone layer.  However, some installers will still use R22 due to its lower cost, so it’s a good idea to check before your air conditioner is installed, and ask for the R410a refrigerant.The disadvantage of choosing an air con with inverter technology is in the initial cost, but since they do save so much when running and are so quiet during their operation, it is certainly worthwhile paying the extra price. Remember, the lesser cost is due to decreased consumption, which translates to increased sustainability.(more…)
