A refrigeration system is to be designed to maintain the temperature in the range of -15°C to -5°C, while the outside temperature varies from 15°C to 25°C. The total thermal load on the storage unit is given as 20 kW. Obtain an initial design for the vapor compression refrigeration system shown below. For safe operation and other factors, such as additional energy transfer, design the system using a safety factor of 1.3 such that QL = 26 kW. The compressor efficiency could range from 60 to 80 percent. Using ammonia (NH3) as the working fluid: 1. Determine the temperatures and pressures at the different points in the cycle (points 1, 2, 3, and 4). 2. Determine the coefficient of performance value and the mass flow rate of the working fluid. Please provide picture of tables if used

Question
A refrigeration system is to be designed to maintain the temperature in the range of -15°C to -5°C, while the outside temperature varies from 15°C to 25°C. The total thermal load on the storage unit is given as 20 kW. Obtain an initial design for the vapor compression refrigeration system shown below. For safe operation and other factors, such as additional energy transfer, design the system using a safety factor of 1.3 such that QL = 26 kW. The compressor efficiency could range from 60 to 80 percent.
Using ammonia (NH3) as the working fluid:
1. Determine the temperatures and pressures at the different points in the cycle (points 1, 2, 3, and 4).
2. Determine the coefficient of performance value and the mass flow rate of the working fluid.
