Find the high temperature and the condensing temperature

Question

Problem

1. Repeat the previous problem with R-410a as the working fluid. Will that work in an ordinary kitchen?

2. The natural refrigerant carbon dioxide has a fairly low critical temperature. Find the high temperature, the condensing temperature, and the COP if it is used in a standard cycle with high and low pressures of 6 MPa and 3 MPa, respectively.

3. Consider an ideal refrigeration cycle that has a condenser temperature of 45^oC and an evaporator temperature of -15^oC. Determine the COP of this refrigerator for the working fluids R-134a and R-410a.

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
