Long-term performance of a solar water heating system with a novel variable-volume tank

Jiarong Li et al.

Summary: This study introduces a novel variable-volume tank design for solar heating systems, which provides more useful heat and reduces system heat loss compared to conventional systems. Parametric analysis shows that the novel tank system is more resilient to degraded insulation or oversized volume, contributing to a robust heating system.

Energy life cycle cost analysis of various solar water heating systems under Middle East and North Africa region

M. A. Ben Taher et al.

Summary: This study developed and validated a model for solar water heating systems in the Middle East and North Africa region, analyzed the performance with different collectors, evaluated solar fraction values and conducted energetic, exergetic, environmental and economic analysis. Propane water heating is found to be cheaper on a life cycle cost basis than electric and diesel heating, while the use of auxiliary electric generators is suitable for most countries in the Middle East region.

Explicit analytical solution of a differential equation model for solar heating systems

Laszlo Szekely et al.

Summary: In the issue of environmental protection, the widespread application of solar heating systems plays a crucial role. Despite the advantages of analytical solutions for models of solar heating systems, they are relatively rare in literature. This paper introduces a new analytical solution for a two-dimensional ordinary differential equation model of complete collector-storage systems, which is validated against real data with outstanding precision.
