AFUE Annual Fuel Utilization Efficiency. A measure of a gas furnace's efficiency in converting fuel to energy—the higher the rating, the more efficient the unit. Air Conditioner Any device that can change the temperature, humidity or general quality of the air. More specifically, an air conditioner makes your home cooler, by drawing heat energy out of the house and transferring that heat to the outdoors. Air cleaner (also Air Filtration System) Removes airborne allergens from your home. Air Filtration System (also Air Cleaner) Removes airborne allergens from your home. Air handler An air moving and/or mixing unit. Residential air handlers include a blower, a coil, an expansion device, a heater rack and a filter. Heaters for air handlers are sold as accessories. In some models, heaters are factory installed. ASHRAE American Society of Heating, Refrigeration and Air Conditioning Engineers BTU British thermal unit; the amount of heat required to raise or lower the temperature of one pound of water one degree Fahrenheit. The heat extracted from your home by an air conditioner is measured in BTUs. CADR Clean Air Delivery Rate (CADR) provides the number of cubic feet of clean air that a unit delivers each minute. Efficiency of the system times the air flow of the system. CFM Abbreviation for cubic feet per minute, a standard measurement of airflow. A typical system requires 400 cfm per ton of air conditioning. Climatuff® Compressor The Trane Climatuff® Compressor was the world's first successful heat pump compressor. To this day it's the only compressor Trane uses in its residential systems. It's well known for its superior durability, its low noise levels and high efficiency. Compressor This is the heart of an air conditioning or heat pump system. It is part of the outdoor unit and pumps refrigerant in order to meet the cooling requirements of the system. Condenser fan The fan that circulates air over the air-cooled condenser. DOE Department of Energy EER Energy Efficiency Ratio (steady state) ENERGY STAR® Trane’s high efficiency systems carry the ENERGY STAR label. The result of Trane's partnership with the U.S. Department of Energy and the Environmental Protection Agency (EPA), ENERGY STAR products are more energy efficient and help reduce our whole earth's pollution problems. Choosing a Trane ENERGY STAR Comfort System assures homeowners of lower energy bills and improved indoor-air quality for their home. EPA Environmental Protection Agency Fan Any device that creates air currents. FreshEffects™ (also Energy Recovery Ventilator or Trane FreshEffects™) Energy-efficient system to exchange stale indoor air for an equal amount of fresher outdoor air. Furnace That part of the heating system in which the combustion of fossil fuel and transfer of heat occurs. Fuse A metal strip in an electrical circuit that melts and breaks the circuit when excessive current flows through it. The fuse is designed to break in order to save more expensive electrical components. Heat gain Heat added to the conditioned space by infiltration, solar radiation, occupant respiration and lighting. Heat loss The rate of heat transfer from a heated space to the outdoors. Heat pump A mechanical-compression cycle refrigeration system that can be reversed to either heat or cool the controlled space. HVAC Abbreviation for Heating, Ventilating and Air Conditioning. Hybrid system (also Hybrid Heat) This type of system provides energy-efficient comfort for moderate heating conditions. Depending on the weather and your comfort needs, it can use either gas or electricity, with an electric heat pump as the outdoor component and a gas furnace the indoor component. Load calculation Assessed by a dealer, the calculation factors in a number of criteria in your home (square footage, number of windows, year-round weather concerns) and determines what size components you should include as part of your total comfort system. Matched system System includes multiple Trane components designed and engineered to work seamlessly together to enhance overall performance, reliability and efficiency. NATE North American Technician Excellence—certification acknowledging a dealer/technician as one of the most knowledgeable and experienced at installing and servicing high-performance, precision-engineered heating and cooling systems. Operating cost Cost of running your home comfort system, based on energy usage. Packaged system (or Packaged unit) A single cabinet, typically installed outside, that houses both heating and cooling components. Refrigerant lines Two copper lines connecting the outdoor condenser to the indoor evaporator coil. SEER Seasonal Energy Efficiency Ratio; a measure of cooling efficiency for air conditioners and heat pumps. The higher the SEER, the more energy efficient the unit. Ton A unit of measurement used for determining cooling capacity. One ton is the equivalent of 12,000 BTUs per hour. Variable-speed motor(s) The fan motor inside Trane's variable-speed air handlers is designed to vary its speed based on your home's heating and air conditioning requirements. Working in conjunction with your thermostat, it keeps the appropriate-temperature air (e.g. warm air on cold days) circulating throughout your home, reducing temperature variances in your home. It also provides greater air circulation and filtration, better temperature distribution, humidity control, higher efficiency and quiet performance. Zoning System A method of dividing a home into different comfort zones so each zone can be independently controlled depending on use and need; an air conditioning system capable of maintaining varying conditions for various rooms or zones. |
