2. Seasonal energy efficiency ratio - Wikipedia

   en.wikipedia.org/wiki/Seasonal_energy_efficiency...

   The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit's SEER rating the more energy efficient it is. In the U.S., the SEER is the ratio of cooling in British thermal units (BTUs) to the energy consumed in watt-hours.

3. European seasonal energy efficiency ratio - Wikipedia

   en.wikipedia.org/wiki/European_seasonal_energy...

   In the United Kingdom, a Seasonal Energy Efficiency ratio (SEER) for refrigeration and air conditioning products, similar to the ESEER but with different load profile weighting factors, is used for part of the Building Regulations Part L calculations within the Simplified Building Energy Model (SBEM) software, and are used in the production of Energy Performance Certificates (EPC) for new ...

4. Heating seasonal performance factor - Wikipedia

   en.wikipedia.org/wiki/Heating_seasonal...

   Heating seasonal performance factor (HSPF) is a term used in the heating and cooling industry. HSPF is specifically used to measure the efficiency of air source heat pumps.

   Here are the conversion factors for those various expressions of wind speed: 1 m/s = 2.237 statute mile/h = 1.944 knots 1 knot = 1.151 statute mile/h = 0.514 m/s 1 statute mile/h = 0.869 knots = 0.447 m/s. Note: 1 statute mile = 5,280 feet = 1,609 meters

6. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   Less work is required to move heat than for conversion into heat, and because of this, heat pumps, air conditioners and refrigeration systems can have a coefficient of performance greater than one. The COP is highly dependent on operating conditions, especially absolute temperature and relative temperature between sink and system, and is often ...

7. Talk:Seasonal energy efficiency ratio - Wikipedia

   seer = BTU/watt-hr. The SEER Rating. Also, although the SEER is commonly defined as a ratio, and would therefore change or vary with operational conditions of the system, the SEER is also (and perhaps upmost) a rating determined by the manufacturer of the system, and therefore has the contrasting property of being a fixed quantity.
