Summary
Different designs of PCM storages are experimented. In a first step, the experimental observations support an analytical description of the charge and discharge process of an encapsulated PCM storage.
In a second step, a more sophisticated numerical model is used to predict the transient behavior of the encapsulated PCM unit during its charging, discharging and relaxation periods. The resulting computer code is TRNSYS compatible. Numerical simulations compare well with experiments.
Using the TRNSYS program, the performance of solar air space heating systems relying on either PCM or RB (Rock Bed) storage units are investigated and compared on both daily and seasonal basis. PCM decreases by a factor 4.5 the storage volume in respect to the RB. The conclusions of the thermal study are processed by a micro-economic model to determine payback periods.
