New Advances in Duct Free Split Systems
The duct free split air conditioning or heat pump system is quickly becoming the go-to system for conditioning smaller or challenging spaces. A duct free system has inherent advantages in that it has no air or thermal losses from duct work since it delivers the conditioned air directly from an indoor air handler. The recent advances in these systems, also called mini-splits, make them even more efficient than ever. Inverter Technology The most significant advance in ductless technology lies in the compressor design. The compressor in any kind of air conditioner or heat pump is the work horse of the system and the one that uses the most energy, much of which when it first starts. Duct free systems that use inverter technology keep the compressor running at different speeds based on the amount of conditioned air the room needs. Instead of turning off abruptly, like most compressors do, it continues to run, although at a much lower speed. Inverter compressors use less electricity, create less noise, and tend to last longer than their single-speed counterparts, since they’re not subject to frequent starts and stops. Another benefit of inverter technology in duct free split systems is better humidity removal in cooling mode. Since it normally runs at a low speed, more air passes over the evaporator coil that contains the chilled refrigerant, allowing more water vapor to condense and drain away. Scroll Compressors Ductless heat pumps equipped with scroll compressors provide much more heating capability, even at temperatures below freezing when there’s less heat in the outside air to harvest. Such a compressor can deliver up to 15 degrees F warmer air than a standard piston compressor. You can find scroll compressors in mini-splits that use variable technology that offer even greater energy savings and comfort, especially when it’s installed to optimize its heating potential for our cold winters. Air Cleaning Many mini splits use air filters that trap indoor particulates exceptionally well, providing effective air quality management as well as efficient cooling and heating.
