Technology never stands still, and that means that the science behind refrigerant-based air conditioners is always finding new ways to cool better and cool more efficiently. Today’s air conditioners can have efficiency ratings that dwarf older models. Where central air conditioners once had SEER ratings below 12, the modern high-efficiency air conditioners can score SEER ratings in the 20s, almost doubling how efficiently they change electricity into cooling output.
If you have an AC that’s more than 15 years old, replacing it with any new system will be an efficiency improvement. But special high-efficiency units can make amazing differences. We’re here to explain exactly what the difference is with these advanced units that allow them to significantly reduce energy use.
Better Construction, Better Refrigerant
This applies to all modern ACs, but we want to point it out. Air conditioners today have thinner materials in their cooling coils, which improves heat transference. The change over from older R-22 refrigerant (which will be completely phased out by 2020) to R-410A also improves efficiency.
Variable Speed Blower Fans
The blower fan in the air handler is responsible for moving warm indoor air from the return vents across the evaporator coil, which cools the air and then sends it into the ventilation system. On a standard air conditioner, this fan runs at only a single speed. It’s either on or off. No matter how much cooling the home needs, the fan runs at that speed and consumes the maximum amount of energy.
High efficiency air conditioners use variable speed fans, which are capable of working at lower capacities. On most days, the fan will work at a lower capacity 60% of the time that its running, cycling lower as necessary. This not only lowers how much power the air conditioner uses, it improves the even distribution of cooling around the house, avoiding creating spots that are too cold.
The compressor is the part of an air conditioning system that consumes the largest amount of power. Like the blower fan, the compressor in a conventional air conditioner works at only a single capacity: on or off. The multi-stage compressor powers up through its different capacities and doesn’t have to work at its maximum unless necessary. This makes a huge difference in air conditioner efficiency.
Multi-stage blowers are also helpful for homes that want to use a zone control system that shuts off airflow to rooms that don’t need cooling. The compressor will only work hard enough to cool the rooms that require it.
