show that cop of heat pump is greater than cop of refrigerator by unity
Answers
Answer:
A refrigerator is an apparatus that runs in cycles and keeps a certain body's temperature lower than the ambient temperature. Additionally, the goal of a heat pump is to maintain body temperature B at a higher level than the ambient temperature.
[COP]H.P. = 1 + [COP]ref
Explanation:
Step : 1 Keep in mind that the orientation of a heat pump affects its COP. Since more heat is rejected to the hot sink than is taken in from the cold source, the heating COP is one higher than the cooling COP. Consequently, the COP (heat pump) is always larger than 1. Since then, COP(heat pump)=1+COP (refrigerator). In the worst case scenario, the heat pump's COP is equal to 1, while the refrigerator's COP is zero. COP(refrigerator) can be any value larger than 0 and spans from 0 to any other number.
Step : 2 The COP is best described as follows: COP = (What you Get)/ (What you Pay For). A heat pump is a desirable appliance since this performance metric can have a value larger than unity. The second rule of thermodynamics states that the COP for heat pumps is always larger than 1. The ratio of "Coldness" generated to "Heat" or "Work" given is known as the coefficient of performance (COP).
Step : 3 Because the compressor's work is only used in the heating mode, the COP for cooling is lower than for heating. The needed inside temperature and the outside temperature have a significant impact on the COP. The COP for vapour compression cycles will always be larger than one. The efficiency of the system will be larger than one if the value of COP is less than one.
