Carnot refrigeration cycle

refrigerator or heat pump that operates on the reversed Carnot cycle is called a Carnot refrigerator or a Carnot heat pump. Fig. 5-1: T-s diagram and major components for Carnot refrigerator. The reversed Carnot cycle is the most efficient refrigeration cycle operating between two specified temperature levels. It sets the highest theoretical COP The Carnot refrigeration cycle can be achieved if one reverses all the processes in the Carnot power cycle. In this case, heat in the amount of Q L is received by the gas from a heat sink and heat in the amount of Q H is rejected to a heat source, and a work input of W net,in is required to accomplish the cycle 14.3. Carnot Refrigeration Cycle In Chapter 7 , we discovered that refrigerators, air conditioners, and heat pumps usually have actual thermal efficiencies in excess of 100%. This is due simply to the mathematical way in which their thermal efficiencies are defined (the desired energy output divided by the required energy input) and does not imply the violation of any physical law

  1. Unlike the Carnot heat engine, the Carnot refrigeration cycle undergoes a process with opposite direction. We see from the model, heat Q L is absorbed from the low-temperature reservoir (T L =constant) and heat Q H is rejected to a high-temperature reservoir (T H =constant). In this case a work input in the amount of W rev is required to achieve.
  2. Reversed Carnot Cycle Carnot cycle is a totally reversible cycle which consists of two reversible isothermal processes and two isentropic processes. It has the maximum efficiency for a given temperature limit. Since it is a reversible cycle, all four processes can be reversed
  3. Reversed Carnot Cycle. The Carnot cycle heat-engine can be called as a fully reversible cycle. That is all the processes that form can be reversed, in which case it becomes the Carnot refrigeration cycle. This time, the cycle remains the same but the directions of heat and work interactions are reversed
  4. when the reversed Carnot cycle is used. Recall that in the Carnot cycle heat transfers take place at constant temperature. If our interest is the cooling load, the cycle is called the Carnot refrigerator. If our interest is the heat load, the cycle is called the Carnot heat pump
  5. The Carnot cycle is a reversible cycle so the four processes that comprise it, two isothermal and two isentropic, can also be reversed. When a Carnot cycle runs reversely, it is called a reversed Carnot cycle. A refrigerator or heat pump that acts on the reversed Carnot cycle is called a Carnot refrigerator or Carnot heat pump respectively

Carnot cycle is ideal cycle which is used for comparison with actual cycle. It is imaginary cycle can not be created we discuss in limitation points why we can not used in actually.Practically, the reversed Carnot cycle cannot be used for refrigeration purpose as the isentropic process requires very high speed operation, whereas the isothermal process requires very low speed operation REFRIGERATION CYCLES Carnot Cycle We start discussing the well-known Carnot cycle in its refrigeration mode. Figure 1: Carnot Cycle In this cycle we define the coefficient of performance as follows: LL HL qT COP wT T == − (1) Which comes from the fact that wq q= HL− (first law) and qTsLL= Δ , qTsHH=Δ (second law) A thermodynamic refrigeration cycle removes heat from a low-temperature object (refrigeration) and rejects it at a higher temperature. This cyclic process requires that work be input so that the second law of thermodynamics is not violated (Wark, 1983). The ideal refrigeration system is based on the concept of the reversible Carnot cycle. The Carnot cycle is a theoretical concept because it is ideal, which means that it is lossless, frictionless, and there are no temperature differences in.

So, in the Carnot Power Cycle Q H and W are positive and Q C is negative. When the Carnot Power Cycle is reversed Q H and W become negative and Q C becomes positive. So in the reversed cycle, work is consumed, heat is received from the cold reservoir and heat is rejected to the hot reservoir. This is a refrigerator ! So, when the Carnot Power Cycle is reversed, it becomes a Carnot Refrigerator or Heat Pump Therefore, the Carnot cycle can be used as a reverse Carnot cycle. After this, the reversed Carnot cycle worked as a refrigerator. For a Carnot cycle, the Q 1 heat is absorbed from the source at temperature T 1 and Q 2 heat is rejected to the sink at temperature T 2.

But Carnot cycle requires infinitely slow operation, and in practice you cannot achieve that. You might achieve just 75% of the efficiency of an ideal Carnot engine. But if that is the interpretation, then if you run at 75% of the Carnot cycle efficiency, then a COP of 10 with 75% efficiency corresponds to a Carnot efficiency of $(0.75*1/10. A Carnot refrigeration cycle absorbs heat at 270 K and rejects it at 300 K. 1. Calculate the coefficient of performance of this refrigeration cycle. 2.
