The Air Conditioning and Refrigeration Institute (ARI) is an organization that was created by HVAC manufacturers to confirm the quality of units within the industry. ARI is a non-profit organization. It is made up of volunteers. It publishes its ratings standards and benchmarks for testing cooling and heating products.
Usually capacity is measured in BTU's or tons. Capacity is the air conditioner or heating unit's effectiveness to cool or heat a measured space. A 20 ton air conditioner has double the capacity of a 10-ton unit.
A CFM is a unit utilized to show the activity of volume of air in Cubic Feet per Minute(CFM). For instance a 400 CFM are handle moves 400 cubic feet in a minute.
A compressor is the device which pumps the refrigerant inside the refrigerant lines and the coil. This makes the transfer of heat possible from inside to outside.
The condenser is a coil that distributes heat to the outdoors air. It's function reverses when a heat pump is used.
The Coefficient of Performance is a rating of a heat pump's capacity to efficiently use electricity within its operation. The Air Conditioning and Refrigeration Institute is the agency that provides the Coefficient of Performance at 47 degrees Fahrenheit and 17 degrees Fahrenheit because a heat pump works better at higher, outside-air temperatures.
A db is the relative volume of a sound, short for decibel. The sound of a human voice talking is close to 70 dB. (See also SRN.)
The Department of Energy (DOE) is a federal agency that sets the specifications for efficiency throughout the HVAC Industry. The DOE also monitors the use of sources of energy.
This warm and cool air is then moved to different registers in your home via special, flexible, large-diameter pipes or ducts or sometimes referred to as ducting or ductwork.
Energy Efficiency Ratio is a ratio of the cooling capacity of the air conditioner in BTUs per hour in terms of the total electrical input in watts. This measurement is discovered by evaluating test units to the Air Conditioning and Refrigeration Institute specifications.
Efficiency is a term used to describe how efficiently a heat pump, air conditioner system, or furnace is converting incoming energy to outgoing energy. The higher the number, the more effective the unit, and the lower the operating costs.
The Evaporator Coil is a crucial section of the indoor unit of a heat pump or air conditioner system. It's function bears it's name. When hot air passes over a coil filled with liquid refrigerant, the refrigerant evaporates and absorbs some of the heat. Then the gas refrigerant is pumped to the outdoor coil, where after that it sends the heat it absorbed back into the outside air and returns to the liquid state.
Heating, Ventilating and Air Conditioning. This term is used to relate to the industry at large, including dealers of heating and air cooling equipment.
The indoor coil is the device responsible for transferring heat from indoors to the outdoors (and the reverse in the case of a heat pump in heating mode.
A kilowatt (kW) is used to describe a unit such as 1,000 Watts. Note that the "W" in "kW" is always shown capitalized because the Watt unit was named after a Scottish engineer named James Watt (1736-1819).
If a unit uses 1,000 Watts in one hour, it is has an energy rating of 1kWh.
A Package Unit is equipment that has all the cooling and heating components inside one cabinet.
The liquid utilized to absorb and transfer heat from one part of the home comfort system to another. Sometimes this is known as as FREON.
The copper lines that are utilized to transfer the refrigerant between the outdoor unit and the indoor unit.
Seasonal Energy Efficiency Rating or SEER is the rating utilized to describe the efficiency of an air conditioner, or heat pump in cooling mode. If the SEER number is higher then the unit is more efficient. The Department of Energy's minimum SEER number rating is 10.
An air conditioning unit which utilizes both indoor together with outdoor components to provide clean comfortable air into a living environment.
A device that is used to manage the temperature of your home comfort systems to maintain a comfortable temperature during the day and night within the house. Some of these are programmable thermostats permitting you to program different temperatures many different times throughout the day.
The ton ratings actually have nothing to do with the weight of the unit. A ton is simply 12,000 BTUs (see BTU definition in this article). A standard home cooling/heating system uses heat pumps or air conditioners with capacities of between 1.5 and 5 tons.
Electrical energy is also expressed as "W" for Watts. For instance, a 200W light bulb consumes 200Watts of electrical power. The W in Watt is always uppercased, since it is named after a Scottish engineer named James Watt (1736-1819).
A house can be divided into several different areas or zones to better control the temperature ranges in your home. The zoning process uses this type of method to divide your home into different areas.
