The refrigeration cycle TS (temperature-entropy) diagram is a graphical representation of the thermodynamic processes occurring within a refrigeration system. It depicts the relationship between the temperature and entropy of the refrigerant as it undergoes four key processes: compression, condensation, expansion, and evaporation. This diagram serves as a valuable tool for engineers and technicians to analyze and optimize the performance of refrigeration systems.
Structure of Refrigeration Cycle T-s Diagram
A refrigeration cycle is the process by which heat is transferred from a cold reservoir to a hot reservoir. The cycle is typically represented on a temperature-entropy (T-s) diagram. The T-s diagram is a graphical representation of the relationship between the temperature and entropy of a system.
The T-s diagram for a refrigeration cycle consists of four processes:
- The compression process: In the compression process, the refrigerant is compressed from a low pressure to a high pressure. This process occurs in the compressor.
- The condensation process: In the condensation process, the refrigerant is condensed from a gas to a liquid. This process occurs in the condenser.
- The expansion process: In the expansion process, the refrigerant is expanded from a high pressure to a low pressure. This process occurs in the expansion valve.
- The evaporation process: In the evaporation process, the refrigerant is evaporated from a liquid to a gas. This process occurs in the evaporator.
The T-s diagram for a refrigeration cycle is shown below:

The four processes of the refrigeration cycle are represented by the four lines on the T-s diagram. The compression process is represented by the line from point 1 to point 2. The condensation process is represented by the line from point 2 to point 3. The expansion process is represented by the line from point 3 to point 4. The evaporation process is represented by the line from point 4 to point 1.
The area inside the T-s diagram represents the work done by the refrigeration cycle. The work done by the cycle is equal to the difference between the heat removed from the cold reservoir and the heat added to the hot reservoir.
The T-s diagram is a useful tool for understanding the operation of a refrigeration cycle. The diagram can be used to calculate the efficiency of the cycle and to identify areas for improvement.
Question 1: What is a refrigeration cycle TS diagram?
Answer:
– A refrigeration cycle TS diagram is a graphical representation of the thermodynamic changes that occur during a refrigeration cycle.
– The diagram plots temperature (T) on the vertical axis and entropy (S) on the horizontal axis.
– It shows the path of the refrigerant as it undergoes the refrigeration process, including compression, condensation, expansion, and evaporation.
Question 2: What are the main features of a refrigeration cycle TS diagram?
Answer:
– The refrigeration cycle TS diagram has four distinct regions:
— Compression: Line connecting 1 to 2 , where the refrigerant’s temperature and pressure increase.
— Condensation: Line connecting 2 to 3 , where the refrigerant’s temperature decreases while its pressure remains constant.
— Expansion: Line connecting 3 to 4 , where the refrigerant’s temperature and pressure decrease.
— Evaporation: Line connecting 4 to 1 , where the refrigerant’s temperature increases while its pressure remains constant.
Question 3: How is a refrigeration cycle TS diagram used?
Answer:
– Refrigeration cycle TS diagrams are used to:
— Analyze the performance of a refrigeration system.
— Identify areas for improvement in efficiency.
— Compare different refrigeration cycles.
— Design and optimize refrigeration systems.
