CALOR REJEITADO CONDENSADOR DISPOSITIVO DE EXPANSÃO EVAPORADOR 2 We COMPRESSOR CALOR ABSORVIDO
As an engineer responsible for monitoring works in the area of
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.

For simplification purposes, you modeled the system as an ideal cycle, neglecting some effects of pressure loss on the components.
Given this information, determine the following parameters for the system:
1 – What is the coefficient of performance (COP) of the refrigeration system?
Note: remember that 1 TR = 3.517 kW
Knowing that the system was initially designed to meet a thermal load of 5.0 TR, do you assess that the system is operating properly? Is the system undersized or oversized? Justify your answer.
Do it in a typeable way, in Word or virtual calculation, the handwriting hinders understanding.
