1. An Inventor claims to have developed a refrigeration unit that maintains the refrigerated space at -10 °C while operating in a room where the temperature is 25 °C, and that has a coefficient of performance of 8.5. How do you evaluate this claim? How would you evaluate the claim of a coefficient of performance of 7.0?

The previous Bartleby person that answered my questions BUT I dont understand were he got the answers from . I NEED HELP to replicate. I have ticked the parts I understood and been able to replicate. Given the table of results find the following. Give answers in KW. Please show all working out Rate of heat transfer to evaporator from the chilled water: Answer : 0.60KW ✓ Rate of heat transfer from condenser to the cooling water: Answer : 0.764KW ✓ Rate of heat transfer to refrigerant in “Evaporator” using enthalpy values: Answer: 1.5: I DON’T UNDERSTAND the answer given – see below Rate of heat transfer from refrigerant in “Condenser” using enthalpy values Work input from the compressor to the refrigerant using enthalpy values The previous Bartleby answer stated that at P1 =288 KPa and T1 =3.48 h1= 253.66 KJ/Kg P2 =823 KPa and T2 =65 h2= 301.48 KJ/Kg Given P3 =815 KPa and T3 =30.4 h3= 94.2 KJ/Kg (I don’t understand where the 94.2 comes from) P4 =294 KPa…
30. A cylinder contains an amount of gas. At pressure of 470 kPa and at temperature of 27 ̊C, thegas occupies a volume of 0.03 m3. It is then compressed according to Boyle’s law until its pressureis 1.3 MPa, and then expanded according to Charles’ Law until its volume is 0.02 m3. Calculate thefinal temperature of the gas. a. 292.35000C b. 248.85000C c. 216.22500C d. 280.31810C
