WebCOP heat pump = 308K/ (308K-287K) = 14,67. So, in theory, a heat pump can have a COP even above 10. Nonetheless, the real COP of a heat pump in practice is a lot lower. Golden standard: The standard test to measure the COP of a heat pump is conducted with T hot = 95F (308K) and T cold = 32F (273K). WebThe SI unit is watt (W). Another unit common in non-metric regions or sectors is the ton of refrigeration, which describes the amount of water at freezing temperature that can be …
