Problem Statement: An ideal absorption refrigerator receives heat from a solar collector at a rate of 5.51 800 kPa and 200 kPa and provide 10 tons of refrigeration. 0.01 20 10 1.00 kg/s. The environment is at an average of 15 -18.85 (b) Area of solar panel required Compressor equivalent Schematic: · Physical Laws: 0.23 per day Properties: 10 tons = 120000 Btu/hr = 35.169 kW 4.200 kJ/kg*K 1.006 kJ/kg*K kWH/m 2 *day (solar panel insolation rate in Jefferson Count The NH 3 system is designed to operate between The PUMP is supplied by a photovoltaic cell embedded in the solar panel which supplies kW. The Q COOL can be provided by a river at o C and heats by o C after going through the absorber at o C and the refrigerated space is to be maintained at o C.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
