Air conditioner ratingAir conditioner ratings – consumer guide to energy efficient air conditioning. A/C by different brands rated and reviewed.
Air conditioner rating is measured by EER (energy efficiency rating). The higher the number – more efficient you’re a/C unit is. The older units only have a rating or 6 or 7. While best modern air conditioners have efficiency rating of 12 or higher. That basically mean that they consume almost twice less energy while cooling your house. When searching for a A/C unit with high efficiency rating look for units with an Energy Star. Earning an Energy Star means that this unit has high rating. Air conditioners are no longer luxury – prices of window and portable units are very affordable. You can find four main types of air conditioning systems: window-wall
units, portable air conditioners, split systems, and ducted systems.
Window-wall units are placed in windows and are used for cooling
smaller rooms. Central air conditioners use ducting pipes that are
placed in the ceiling. These pipes route the cool air through ceiling
vents or “ducts” in each room. Split system air conditioners
consist of two main sections – a quite unit inside and a compressor
that's placed on the outside.
How Air Conditioning WorksTo cool your room air conditioning systems removes heat and moisture from the indoor air and transfers it outdoors. All air conditioning systems work on the same principle - they have a chemical refrigerant that absorbs the unwanted heat and then pumps it through a system of piping to the outside coil. After that the fan blows outside air over the hot coil to transfer heat from the refrigerant to the outside air. Air conditioner rating is important because even though high efficiency
air conditioners are a little more expensive than traditional units,
they use 20%-50% less energy. That represents a sizeable amount
of overall savings. So in a long run a high rating unit will you’re
your less. Also for an air conditioning system to work efficiently
proper sizing is very important. Sunpentown
