The system was fabricated out of various designs of HPHE with different wick structures, i.e., sintered and meshed wick types as discussed by Sharma (2012).
Design details of the HPHE are presented in Table 2.
Rows of heat pipes in this type of U-shaped HPHE were arranged in a staggered manner.
Assembly of Heat Pipes with Fin Structure and Final HPHE
For proper assembly, some more tasks were performed--manual support was provided for alignment of the fin pusher during the fin assembly process, chamfering and widening the fin pusher jig holes to make easy penetration of heat pipes inside the holes, and straightening the HPHE misalignment.
The final U-shaped HPHE after complete assembly is shown in Figure 6c.
To test the performance of the U-shaped HPHE, an experimental test facility was created in the Refrigeration and Air-Conditioning Laboratory at the Indian Institute of Technology (IIT) Delhi, as per the schematic diagram shown in Figure 7 and test rig photograph in Figure 8.
Special flanges of suitable dimensions were also prepared for fixing the flanges with the cooling coil and the U-shaped HPHE. The U-shaped HPHE was wrapped around the three-row DX cooling coil of 2.81 kW (0.8 TR) (9588 Btu/h) cooling capacity and charged with R-22 refrigerant.
The experimental performance of the U-shaped HPHE in terms of effectiveness e and the COP of the heat-pipe-assisted air-conditioning system were evaluated.
To explore the potential of HPHE for the Indian climates, payback analysis was carried out.
For the same reason, fan power was not included as it was not measured in the experimental performance of the HPHE.
The payback period estimation is based on the reheat energy and cooling coil energy savings achieved by using the HPHE. Cooling coil energy savings is precool energy savings divided by the COP of the chiller.
