Pilot-scale field tests of high efficiency heat transportation system "Thermo Way" is carried out. This system uses phase change material (Erythritol) as heat storage media for high storage density. Thermal storage cassette can be mounted on truck so that heat can be transported from waste heat emitting site to heat consumption site. 4ton pilot-scale thermal storage cassette is designed and manufactured and used in the test series. In the field test, after transportation of 35km on road, constant thermal recovery and hot water supply at 90℃ for more than 8 hours are achieved. Thermal recovery efficiency is calculated to be more than 90%, showing high performance. Load change test is also examined to simulate actual heat consumption. Changing heat load, which is a combination of constant air condition load and intermittent 60℃ hot water supply, is connected to thermal recovery unit. PID-control loop installed in the thermal recovery unit responded successfully, matching the heat supply to the varying heat demand.
