System Superiority
When designed around a consumer’s lifestyle and specific needs, a Trane system is the best long-term solution for providing a superior level of indoor comfort.
A Trane comfort system is just that – a system that is completely integrated into a home’s indoor environment, enhancing its livability, room by room by room. In the following chapters, you will learn why Trane components are extremely reliable, durable and efficient. When these components are combined into a system, you can imagine the impact they can make in a home’s comfort. At Trane, we believe that any comfort challenge can be overcome by the selection of the right heating and air conditioning system. By working closely with consumers, a Trane dealer can provide comfort solutions for a consumer’s home and years of worry-free satisfaction.
Trane systems are highly flexible. They are engineered to offer options in terms of capacity, airflow, humidity control, air filtration, energy use and operating efficiency. There are also options in thermostats and zoning and system controls.
Only A Complete System Can Provide Complete Comfort.
The performance and efficiency of an outdoor unit is based on its being matched with a similarly engineered indoor unit of like size and capacity. In other words, it is not assigned an efficiency rating independently as a separate component. An air conditioner or heat pump is assigned an efficiency rating as part of matched system. If a new, high efficient outdoor unit is installed without replacing the evaporator coil, it is immediately a mismatched system and will not achieve the SEER rating indicated on its EPA hang tag. In fact, its efficiency rating will be rendered indeterminable at best. Studies have shown that if an old coil is not replaced when a new outdoor unit is installed, the new unit could actually suffer more than a 20% decline in SEER.
By the same token, the cooling or heating capacity can also be affected. Studies have shown, that if an old coil is not replaced, a system could realize as much as a 10% loss in capacity.
Reliability also becomes an issue with a mismatched system. An older coil is usually a
dirty coil. And a dirty coil causes the compressor in the outdoor unit to work harder than it should, which could ultimately shorten its life. A mismatched system is not the best comfort choice for a consumer, particularly if the consumer is purchasing a high efficiency outdoor unit in order to reduce energy use.
Every Trane System Is Built With Efficiency In Mind.
Every Trane comfort system has been designed to attain the highest level of performance with the least amount of energy use. For example, Trane furnaces have key furnace control functions integrated into one microelectronic system,
which constantly monitors, analyzes and regulates the operation of the gas burner, the induced draft motor and the indoor fan. The multi-port in-shot burner perfectly shapes the flame cone for the maximum heat possible, while using the least amount of fuel. Each burner is fired at 20,000 BTUH, which is significantly less than many other furnaces in the industry. This lower BTUH leads to long-life and reliability. Another efficiency feature is the adaptive hot surface silicon nitride igniter, which starts burners electrically, eliminating a wasteful pilot light.
Trane’s variable speed air handlers are also highly efficient. Equipped with an ICM (Integrally Controlled Motor), these units achieve significant energy savings. A standard motor only has an “off” and “on” speed, which means it runs at maximum capacity when it’s on. An ICM motor automatically varies its speed between zero and maximum and has slow ramp-up capabilities, which allows it to use very little energy. It also offers continuous comfort and quiet operation. When matched with the appropriate outdoor unit, you can create a highly efficient system, which provides greater comfort and a lower cost of operation.
