Hello all, this is related to a project that I am working on. It is not directly related to the project but as part of it, I thought it would be a good idea to check the temperature difference that I need to maintain in order to effectively transfer a certain amount of heat between the TH in a refrigeration cycle and the environment. The heat that I need to transfer is the amount of heat generated by the human body while performing physical activities. The rate is averaged at 400 W. For 8 hours that is a total of 11520 kJ of heat. The environment is on Mars where the atmosphere is 100 times thinner than Earth. Thanks in advance!
