GLOSSARY OF TERMS AFUE The measure of seasonal or annual efficiency of a furnace or boiler. It takes into account the cyclic on/off operation and associated energy losses of the heating unit as it responds to changes in the load, which in turn is affected by changes in weather and occupant controls BTUH A British Thermal Unit (BTU) is the unit of heat required to raise 1 pound of water by 1 degree Fahrenheit. BTUH is British Thermal Units per Hour. CFM Stands for Cubic Feet per Minute. A measurement of airflow that indicates how many cubic feet of air pass by a stationary point in one minute. The higher the number, the more air is being forced through the system. COMFORTHEAT Carrier's exclusive ComfortHeat technology accurately predicts the need for heating while cutting temperature swings in half. DB Decibels are a unit measuring the intensity of noise. EER Energy Efficiency Ratings measure the efficiency with which a product uses energy to function. It is calculated by dividing a product's BTU output by its wattage. ENERGY STAR Energy Star is a government-backed program helping businesses and individuals protect the environment through superior energy efficiency. Products with the Energy Star rating will be efficient and save cost on energy bills HSPF The Heating Seasonal Performance Factor is a measure of the heating efficiency of a heat pump. The higher the HSPF number, the more efficiently the heat pump heats your home. IDEALHUMIDITY IdealHumidity™ is Carrier's proprietary humidity management innovation for maintaining the ideal comfort in a home MERV The Minimum Efficiency Reporting Value is the standard comparison of the efficiency of an air filter. The MERV scale ranges from 1 (least efficient) to 16 (most efficient), and measures a filter's ability remove particles from 3 to 10 microns in size. MICRON A unit of measurement defined as one thousandth of a millimeter or one 25th of a thousandth of an inch. A human hair is 50 microns wide PURON Puron® Refrigerant is an environmentally sound refrigerant designed not to harm the earth's ozone layer. Federal law requires that all manufacturers phase out ozone depleting refrigerants in the next few years. Puron Refrigerant is approved by the US Environmental Protection Agency as a replacement from Freon 22. QUIETECH QuieTech™ is a noise reduction system that provides comfortable heat while generating very little noise in the process SEER The Seasonal Energy Efficiency Ratio is a measure of the cooling efficiency of your air conditioner or heat pump. The higher the SEER number, the more efficient the system is at converting electricity into cooling power. SERPENTUFF Carrier's exclusive Serpentuff™ Heat Exchanger features a patented polypropylene laminate, so that it extracts nearly all of the heat from the system and makes the most of the energy used. SILENCER SYSTEM Carrier Silencer System II ensures quite operation inside and out. Our systems meet or exceed local and industry sound standards with quiet motor mounts, a compressor sound blanket, forward swept fan blades, a laminated sound elimination compressor mounting plate and a a unique top with integrated silencer airflow baffle. SMARTRECOVERY Smart Recovery starts the system in advance to be sure that each zone reaches your selected temperature setting at the scheduled time. THERMIDISTAT The Thermidistat™ Control monitors temperatures both inside and outside, as well as indoor humidity and adjusts system operation to maintain the temperature and humidity levels set by the homeowner. TXV A thermostatic expansion valve (TXV) is precision device used to meter the flow of liquid refrigerant entering the evaporator at a rate that matches the amount of refrigerant being boiled off in the evaporator. TRUESENSE TrueSense™ dirty filter detection reminds you when it's time to change your media filter WEATHERARMOR WeatherArmor™ is a Carrier innovation that protects outdoor units from weather and increases durability. ZONING A way to increase your home comfort and energy efficiency by controlling when and where heating and cooling occurs in a home. Programmable thermostats are used to control operating times of the equipment. Dampers are used to direct air flow to certain parts or "zones" of the home. Water control valves are used in boiler systems to direct water to parts of the home. |
