I am doing a project for my thermodynamics class and we have to choose a compressor for a a vapor compression refrigeration cycle that has a heat transfer rate of 1500 btu/h and must maintain 0F in the freezer when the room temp is 90F. I have went through some calculations to find the mass flow rate and compressor power but i have to estimate the length of compressor tubing. I am using the eqn Q=hA(Tfluid-Tsurrouding) I chose to use copper as the tubing but I cannot find h or the temperature of the fluid. Any help with this is appreciated. I also need help with what the tube inside and outside diameter should be.
Also what temperatures should the cycle be designed for based on the contraints given?
