Personal comfort systems, which reduce the conditioned air volume to individual body parts or effective areas of the user, for summer cooling are being investigated. The use of phase change materials allows cooling without a chiller. The developed cooling element limits cooling to the user's hands and torso. With a maximum electrical power requirement of 1.3 W, an average temperature difference of 2.2 K can be achieved over a period of three hours at a room temperature of 27 °C via the cooling element. The cooling capacity is 18.5 W with a COP of 18.12. In addition to the energy evaluation, the positive influence of the phase change material cooling element on thermal comfort is confirmed in a field study with ten participants using questionnaires.
