What is inverter aircon? Why is it so popular now?
Let us begin with the explanation of a non-inverter aircon first. In layman terms, a non-inverter aircon has a cooling system designed to operate at single speed (i.e. either “Power on” or “Power off”). When the aircon reaches its pre-set temperature, it stops blowing cold air and starts blowing non-cold air due to the shutting down of cooling system (i.e. “Power off” or “Fan” mode and blowing normal air). When the temperature goes above the preset temperature, the aircon would start blowing cold air again (i.e. switch to “Cold” mode). The aircon cooling system is made to work at full capacity (“Power on” when blowing cold air) or no capacity (“Power off” when blowing normal air). This is actually very inefficient and put undue stress on the system. The numerous times of “Power on” and “Power off” of the cooling system makes the system works harder and consume more electricity. When the aircon system is made to work harder, its life span would naturally be shortened.
On the other hand, an inverter aircon has a cooling system intelligently designed to operate at multi-speed (i.e. the system adjusts its cooling capacity to meet the cooling needs). The room’s temperature is constantly communicated within the system and cooling capacity is adjusted regularly to respond to the room temperature in a timely manner to minimize drastic temperature fluctuation. When the inverter aircon adjusts its cooling capacity smoothly to respond to the cooling needs of the room, less power is consumed to maintain the pre-set temperature.
An inverter aircon is usually more expensive as compared to a non-inverter aircon. However, over the long run, the cost savings from electricity consumption makes the inverter aircon more worthwhile to own than a non-inverter aircon.
Therefore, always ask for an inverter aircon when you are installing your aircon. Find out more about VRV system which is gaining much popularity in bigger houses recently as well as aircon installation and aircon problems.
