Web$\begingroup$ The text mentions both efficiency and COP, but these have different formulas. Usually COP is the expression used for refrigerators/heat pumps (moving heat from a cold place to a warmer), while efficiency is a term usually used in the case where work and not heat transfer is the goal (engines e.g). The formula shown is for efficiency … WebYes, air source heat pumps work below 20 degrees Fahrenheit —in fact, they can perform well below -10! If you’re worried—or if you live in Antarctica—you can get a cold-climate heat pump with a supplemental heating system in case of emergencies (the vast majority of people never need it). flywoo firefly hex nano gps

Ways of calculating coefficient of performance (COP)

WebHeat Pump. A heat pump is basically a heat engine run in the reverse direction. In other words, a heat pump is a device that is used to transfer heat energy to a thermal reservoir.
