Example: For a heat pump delivering 120,000,000 BTU during the season, when consuming 15,000 kWh, the HSPF can be calculated as : HSPF = 120000000 (BTU) / (1000) / 15000 (kWh) HSPF = 8. The HSPF is related to the non-dimensional Coefficient of Performance (COP) for a heat pump, which measures the ratio of heat delivered to work done by the ...
For example, if the heat rate is 10,500 Btu/kWh, the efficiency is 32.5% (since 3,412 Btu / 10,500 Btu = 32.5%). The higher the heat rate (i.e. the more energy input that is required to produce one unit of electric output), the lower the efficiency of the power plant.
The Btu should not be confused with the Board of Trade Unit (BTU), an obsolete UK synonym for kilowatt hour (1 kW⋅h or 3,412 Btu). The Btu is often used to express the conversion-efficiency of heat into electrical energy in power plants. Figures are quoted in terms of the quantity of heat in Btu required to generate 1 kW⋅h of electrical energy.
The PNR 900 class is a class of 21 GE Universal Series diesel–electric locomotives operated by the Philippine National Railways since 1973. The locomotives comes with three different types: U14CP (1973), U14C (1979), and U15C (1991).
Class 22 was originally designated as Type 122 prior to introduction of the 1971 numbering system. The original numbers were 122.001-122.050. In 1957 the last 10 locos were given dual voltage (1500 and 3000 Volts DC) capability plus a third headlight so they could run on the NS. They were renumbered to 122.201-210.
12,000.00 Btu IT /h 2,593.90 ft⋅lbf/s A ton of refrigeration ( TR or TOR ), also called a refrigeration ton ( RT ), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.
