As an engineer responsible for monitoring works in the area of mechanical systems, you must evaluate the following situation: a large client in the retail area has a refrigeration system where it stores some chilled or frozen products to be sold on the sales floor.Recently, the customer's maintenance department has been questioning the system's performance and requested an evaluation of the system's behavior. You went to the location and requested some information from the maintenance manager about the system, who provided the following data: - The system operates with R-134a refrigerant;- The refrigerated environment is maintained at 0°C and the external environment at 26°C;- The refrigerant flow rate in the system is 0.08 kg/s; In addition to the data provided, you carried out some tests and measured the temperature of the refrigerant fluid at some specific points in the system, such as the compressor inlet and condenser outlet, finding values of 0°C and 26°C respectively.…
