Our analyses provided the amount of energy required to power the RoCo air supply and further compared it to the amount of energy removed from the human body for the cooling mode and the amount of energy loss reduced at the human body for the heating mode. In addition, we analyzed parameters such as the overall cooling-heating capacity, device’s position and distance with respect to the human body, and clothing level to determine their effect on the thermal comfort. As a result of the analyses, increasing the cooling/heating capacity of the RoCo system from 100 W to 150 W allows to create comfortable environments in the heating mode. However, in the cooling mode, the increase in capacity seems to have a neutral effect on the environment around the human body and the body itself. Overall, the research team managed to reconcile the different performance requirements in both the cooling and the heating mode that enables to construct the cheapest possible RoCo device. This performance will be put to test with actual human subjects as all of the current results are based on numerical modeling as a first design step prior to building the RoCo prototypes.
