Patent application: Phase change material pack for air conditioning system

Ben Welter - Tuesday, May 12, 2015

U.S. patent application 20150121944 (assignee: VKR Holding A/S, Denmark): "A phase change material (PCM) pack for an air conditioning system comprises phase change material sealed between a first thermally conductive layer forming a first outer surface of the PCM pack and a second thermally conductive layer forming a second outer surface of the PCM pack. At least the first or second outer surface of the PCM pack takes the form of a substantially planar surface having defined therein a plurality of depressions deviating from the planar surface towards the interior of the PCM pack in a direction perpendicular to the planar surface. The depressions improve heat transfer between the pack and an airflow passing over the surface of the PCM pack."
