**Title: Ideal Vapor Compression Refrigeration Cycle with R-134a** **Educational Content:** **Introduction:** A heat pump operates on the ideal vapor compression refrigeration cycle with R-134a as the working fluid. The cycle operates between the pressure limits of 0.32 MPa and 1.2 MPa. For this exercise, we will calculate the rate of heat supply by the heat pump to the heated space, given a mass flow rate of the refrigerant of 0.25 kg/s. **Cycle Description:** The ideal vapor compression refrigeration cycle consists of four key components: 1. **Evaporator** – The refrigerant absorbs heat from the surroundings and evaporates. 2. **Compressor** – The vapor is compressed to a high-pressure state. 3. **Condenser** – The high-pressure vapor releases heat and condenses. 4. **Expansion Valve** – The liquid refrigerant expands to a low-pressure state. **Diagrams:** 1. **Schematic Diagram of the Heat Pump System:** - The schematic diagram labels the components: Evaporator, Compressor, Condenser, and Expansion Valve. - It illustrates the flow of the refrigerant through these components in a closed loop. 2. **Pressure-Enthalpy Diagram:** - This diagram plots the refrigeration cycle on a Pressure (P) vs. Enthalpy (h) graph. - It shows the four stages: evaporation (low pressure), compression (increased pressure), condensation (high pressure), and expansion (decreased pressure). - The process lines connecting the states are marked accordingly. 3. **Temperature-Entropy Diagram:** - This diagram plots the cycle on a Temperature (T) vs. Entropy (S) graph. - The stages of the cycle are marked, showing the change in temperature and entropy during each phase. - It visualizes the thermodynamic states and their transformations within the cycle. **Calculation:** Given: - Mass flow rate of the refrigerant ( \(\dot{m} \) ): 0.25 kg/s - Pressure limits: 0.32 MPa and 1.2 MPa The rate of heat supply by the heat pump to the heated space can be calculated using the enthalpies at specific states in the cycle. The heat absorbed in the evaporator ( \(\dot{Q} \) ) is given by: \[ \dot{
