WebMar 31, 2024 · COP = Output / Input Coefficient of Performance for heating is, K = QH / Win Where, K = Coefficient of Performance, Q H = The heat pump’s output, W in = The work … WebBoth the COP of a refrigerator and a heat pump can be greater than one. Combining these two equations results in: = + for fixed values of Q H and Q L. This implies that COP HP will be greater than one because COP R will …
WebMay 22, 2024 · From the COP, which is defined as: the amount of heat the heat pump can add to a room is equal to: Qhot = COP heating x W = 3 x 1500 = 4500 W or 4500 J/s In case of the cooling mode, the heat pump (air conditioner) with 1500 W motor can take heat Qcold from inside the house and then dump Q hot = 4500 W to the hot outside. http://labman.phys.utk.edu/phys136core/modules/m3/refrigerators.html
WebA refrigerator has a COP of 4.8 and uses 400 J of work. Determine the heat transferred and the efficiency of the refrigerator. We use the COP formula and substitute the value of the coefficient of performance and work to find the heat transferred. C O P r e f = Q C W ⇒ Q C = C O P r e f · W = 4. 8 · 400 Q C = 1920 J
WebUsing this equation with COP = 1.8 and T0 = 25°C we determine T =−81.3°C. This is the temperature a heat reservoir would have if a Carnot refrigerator with a COP of 1.8 operated between this reservoir and another reservoir at 25°C.
