Webcooling system and according to the requirement optimum changes are carried out on the system to get the best thermal performance. The general measure of efficiency of a TEC is based on the amount of heat that it removes compared to the amount of work that it requires. This value is referred to as coefficient of performance, COP. WebThe co-efficient of performance of a refrigeration system is given by the ratio of heat absorb, to the work input. COP = Heat removed by refrigerant / Power input = m x CpΔT / K.Wh Where, m = mass of water kept in cooling chamber Cp = specific heat of water = 4.18 Kj /Kg K ΔT = temperature of cooling water K

WebFeb 15, 2024 · The COP is a performance rating, which tells you how effective your heat pump system or a refrigerator is at moving heat against the power consumed.
