shell, polycarbonate was selected for this experimental prototype. Polycarbonate is durable, widely available, and easy to use with great heat/corrosion resistance. In addition, this material inherently acts as pseudo-insulator as it has a low thermal conductivity. With good transparency, this material also allows monitoring of the PCM melting and solidification process during lab testing. A helical tube design was chosen for final fabrication. Preliminary CFD simulation and lab testing proved that the spiral tube has better heat transfer performance than straight tubing (Duan et al., 2016). Copper was chosen for the HTF tube due to its exceptionally high thermal conductivity, low cost, and availability. The final design of the storage has the following dimensions: 30.54 cm (1 ft) in length and 16.64 cm (6.55 in) in outer diameter. The top and bottom ends of the container were attached to square grooved acrylic plates with a thickness of 0.9525 cm (3/8 in) and length of 19.05 cm (7.5 in) (Figure 3.1-(a)). Four holes were drilled near each corner of the plates for stainless steel rods later to be inserted through to hold the heat exchanger together by fastening the nuts. Three additional holes were drilled to accommodate thermocouples, an alignment rod to keep the helical coil inline, and an opening for PCM filling and draining purposes. The shell was covered with an insulation blanket made of cryogel, an advanced insulation material, (Scotia Insulations Co.) including top and the bottom plates to prevent heat loss. Helical coil tubing was made from a 315-cm (124 in) long copper pipe with an inner and outer diameter of 0.635 cm (1/4 in) and 0.952 cm (3/8 in), respectively. The coil diameter was chosen as 10.16 cm (4 in) with a pitch of 2.8575 cm (1.125 in) yielding 8.7 turns and 7.62-cm (3 in) long straight tubing extending from the center of the helical coil 34PDF Image | THERMAL ENERGY STORAGE USING PARAFFIN WAX
