2. Uniform Tire Quality Grading - Wikipedia

   en.wikipedia.org/wiki/Uniform_Tire_Quality_Grading

   Uniform Tire Quality Grading, commonly abbreviated as UTQG, is a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction. The UTQG was created by the National Highway Traffic Safety Administration in 1978, a branch of the United States Department of Transportation (DOT). [ 1 ]

4. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   In general, heat pumps work most efficiently (that is, the heat output produced for a given energy input) when the difference between the heat source and the heat sink is small. When using a heat pump for space or water heating, therefore, the heat pump will be most efficient in mild conditions, and decline in efficiency on very cold days.

6. Absorption heat pump - Wikipedia

   en.wikipedia.org/wiki/Absorption_heat_pump

   An absorption heat pump (AHP) is a heat pump driven by thermal energy such as combustion of natural gas, steam solar-heated water, air or geothermal-heated water [1] [2] differently from compression heat pumps that are driven by mechanical energy. [citation needed] AHPs are more complex and require larger units compared to compression heat ...

7. Heat pump and refrigeration cycle - Wikipedia

   en.wikipedia.org/wiki/Heat_pump_and...

   Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]

9. Heating seasonal performance factor - Wikipedia

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

   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 compressor. The HSPF can be converted to a seasonally-averaged COP assuming a lossless compressor and no heat loss by multiplying by the heat/energy equivalence factor .29307111 W·h per BTU.
