The COP relates the condensing heat flow, �̇�𝑄𝐶𝐶 to the consumed electric power of the compressor, 𝑊𝑊𝑠𝑠̇ 𝐶𝐶𝐶𝐶𝐶𝐶 = �̇�𝑄𝐶𝐶 �̇�𝑊𝐶𝐶 (5) The Lorenz COP is the maximum theoretical COP that can be achieved when the heat source and heat sink have variable temperatures.	cache/cet-12755.pdf	txt/cet-12755.txt
