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.
The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]
A cost-performance ratio with a positive value (i.e. greater than 1) indicates that costs are running under budget. [3] A negative value (i.e. less than 1) indicates that costs are running over budget. [3] However, a neutral cost-performance ratio (between 1.0 and 1.9) could suggest a certain degree of stagnation in the budget.
The heat pump itself can be improved by increasing the size of the internal heat exchangers, which in turn increases the efficiency (and the cost) relative to the power of the compressor, and also by reducing the system's internal temperature gap over the compressor. Obviously, this latter measure makes some heat pumps unsuitable to produce ...
A freight rate (historically and in ship chartering simply freight [1]) is a price at which a certain cargo is delivered from one point to another. The price depends on the form of the cargo, the mode of transport (truck, ship, train, aircraft), the weight of the cargo, and the distance to the delivery destination.
Carrier and all three of his wives are buried in Forest Lawn Cemetery in Buffalo, New York. [16] Carrier fathered one child, Howard Carter Willis. [citation needed] He also adopted another two children [17] from Jennie Martin, Vernon Gardner Carrier (1903–1985) and Earl Gardner Carrier (1905–1983). Carrier was a Presbyterian. [17] He lived ...
The Fed's 0.50% rate cut on Sept. 18 has sparked hope of lower mortgage rates-- and possibly cheaper house prices. As of Sept. 19, according to data from Freddie Mac, the average 30-year fixed ...
Fort Lauderdale–Hollywood International Airport (IATA: FLL, ICAO: KFLL, FAA LID: FLL) – also known as Fort Lauderdale Airport and historically as Merle Fogg Field and Broward County International Airport – is a major public airport located in Broward County, Florida, United States, roughly 3 miles (4.8 km) southwest of downtown Fort Lauderdale and 21 miles (34 km) north of Miami.
