WebThe cycle and the heat and work transfers are indicated in Figure 3.6. In this mode of operation the cycle works as a refrigerator or heat pump. ``What we pay for'' is the work, and ``what we get'' is the amount of heat … WebThe Coefficient of performance ( K or COP) is a number that describes the effectiveness of heat pumps, refrigerators or air conditioners. The coefficient of performance is different for heating and cooling systems. … hampton tuition 2023
What is Coefficient of Performance – COP - Thermal Engineering
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP usually exceeds 1, especially in heat pumps, because, instead of just converting wor… WebMay 1, 2024 · The exergetic coefficient of performance (COP ex) of the refrigeration system is the second-law efficiency of the cycle. It is defined as the ratio of useful exergy rate, which is the thermal exergy of the heat removed by the evaporator, to the required exergy rate, which is the work done by the compressor. The COP ex can be written as : WebCOP = = c H HP w q Cost Benefit COP = = It can be seen that COPHP =COPR +1 Air conditioners are basically refrigerators whose refrigerated space is a room or a building. The Energy Efficiency Rating (EER): is the amount of heat removed from the cooled space in BTU’s for 1 Wh (watt-hour) EER = 3.412 COP R Most air conditioners have an EER ... hampton tunnel va
