Variable Speed Technology
| While all of Trane’s heating and air conditioning systems are highly efficient, durable and reliable, there’s one choice that stands head and shoulders above the rest. And, that’s our two compressor XL19i systems. These state of the art comfort systems take comfort and efficiency to a new level, offering the consumer a oneof- a-kind comfort experience. Drawing on Trane’s heritage in heat transfer and compressor technology, and marrying it with our highly innovative and tightly integrated cabinet design, these systems offer the quietest and most efficient operation of any comfort system available today. Our XL19i two compressor air conditioning systems offer two-stage cooling, while our XL19i two compressor heat pump systems offer two-stage cooling and three-stage heating. Take a look and see how Trane is raising the bar in home comfort. |

An Experience Unlike Any Other: The XL19i Comfort System.
The Highest Possible Efficiency.
Trane’s two compressor systems offer some of the highest efficiency levels in the industry. In fact, the XL19i air conditioner, which is rated at 19.50 SEER, has the highest efficiency level of any air conditioner available today. Trane’s two compressor XL19i heat pump system is rated at 17.90 SEER in the cooling mode and has an HSPF rating of 8.90 in the heating mode. These ultra high efficiency levels represent a significant annual savings in cooling costs for consumers.
Variable Speed Technology.
The variable speed motor used in XL19i systems is programmed to be a constant airflow blower motor. The drive module controls the motor speed and torque to ensure a constant volume of airflow. If the resistance to airflow in the duct system increases (due to dirty filters, closed registers or other reasons), the drive module immediately detects this and increases the rpm of the motor. When the drive module picks up the higher rpm, it will increase the speed and torque to move more air. When the desired airflow is again achieved, the motor settles into the proper speed. This unique feature of speed variability ensures compressor reliability, proper system capacity and airflow distribution throughout the duct system.
Staged Heating And Cooling.
Instead of operating on a single, full-blast speed, a multiple stage system operates efficiently at a lower speed most of the time. On extremely hot or cold days, it switches to a higher stage to maintain comfort. Because of this, staged heating and cooling puts an end to temperature swings. And, since the system operates at a slower speed much of the time, conditioned air is continuously distributed throughout the home, enhancing comfort and indoor air quality.
Comfort-R™ & Dehumidification.
When variable speed is combined with two compressor systems, airflow delivery can be programmed to deliver 50% airflow during first stage operation and 100% during second stage. This managed process is called Comfort-RTM and it’s set by the installer. During cooling, the motor ramps up slowly – the slow movement of air allows the Comfort™coil to cool quickly which means moisture is extracted from the air. This dehumidification feature removes six times the amount of moisture that a standard system can. It also provides more immediate comfort, allowing a home to get cooler or warmer faster.
Reduced Operating Sound Levels.
Our systems are designed to be quiet, beginning with the heavy steel insulated cabinets and variable speed blower motors in our high efficiency indoor units. With our quiet Climatuff® compressors and sound insulators in our outdoor units, exterior operating sound is minimized as well. The cabinet design of our outdoor products also leads to reduced operating sound, with rattle-resistant panels and top, and a composite basepan which prevents metal on metal vibration.
Enhanced Indoor Air Quality.
With variable speed technology, a constant flow of conditioned air moves through a home, providing a cleaner indoor environment. But, there’s another component of an XL19i system that provides cleaner indoor air – and, that’s an electronic air cleaner. A Perfect Fit electronic air cleaner is up to 40 times more effective than a standard throwaway filter and is up to 99% effective at removing airborne particles. Because it removes particulate matter so effectively, it protects the operating efficiency of the system over time. It’s also energy efficient, using less energy than a 40-watt bulb.
