The Efficiency of a Modified V-Corrugated Zinc Collector on the Performance of Solar Water Heater (Swh)

Review on the Progress of Solar Water Heaters and Their Future Perspectives

“…Table 6 lists some recommendations from this review for future research based on previously conducted studies that have explored collector materials and geometric design. [50,179,180] Table 6. Future research of collector.…”

“…Although structural modifications can enhance the performance of solar collectors, they are not the sole method of improvement; therefore, structural changes are not always necessary. [50] Instead, it is possible to maximize the solar collector's performance by identifying and optimizing operating parameters, such as the angle of inclination, flow rate of the working fluid, and operating temperature. These parameters directly impact the amount of absorbed solar radiation and heat loss, which in turn affect the overall efficiency of the solar collector.…”

“…[87] Interestingly, the fluid's volumetric flow rate is a key determinant of collector efficiency. [50] Yet, so far, research has not defined an ideal value. To improve FPC performance, researchers have explored different strategies like enhancing absorber absorption, improving heat transfer between the absorber plate and tube, [88] decreasing boundary layer thickness within the receiver tube, and even amending environmental factors.…”

“…Changes in the collector design structure are one of the main factors to enhance the performance and efficiency of the SWH. [50] The design parameters of the FPC affect its performance in absorbing solar heat and losing heat, especially on the top and bottom sides of the collector through convection and conduction.…”
