This study examines the effect of an air-based solar heating system that can be used directly for convection heating while minimizing thermal leakage. To compare the effect of reducing the heating and hot water load when using the system, a simulation model of the system is created, and annual load calculations are performed. The results of the simulation study show that the annual heating load is reduced by 5.39 GJ and the hot water load is reduced by 10.32 GJ when using the air-based solar heating system, resulting in a 48.3% annual load reduction effect. In addition, by analyzing the thermal balance of the indoor space based on the application of the air-based solar heating system, the problem of the existing system is elucidated. In order to improve the performance of the system as shown in the thermal balance, it is necessary not only to improve the performance of the collector, but also to review its thermal storage, insulation, and proper control.

“…In another experimental study, the thermal behavior of different working fluids in an FPHPSC was compared: R410A performed better compared with R407c and R-134a and resulted in the maximum thermal efficiency of ~59% [62]. Wei et al [63] also proposed the utilization of continuous heat pipes in a new design of FPHPSC, where two horizontally linked pipes were used on two ends of the collector and one pipe was considered for returning the working fluid from the upper collected pipe to the bottom one ( Fig. 11).…”

Among all the available solutions to the current high energy demand and consequent economic and environmental problems, solar energy, without any doubt, is one of the most promising and widespread solutions. However, conventional solar systems face some intractable challenges affecting their technical performance and economic feasibility. To overcome these challenges, increasing attention has been drawn towards the utilization of heat pipes, as an efficient heat transfer technology, in conventional solar systems. To the authors' knowledge, despite many valuable studies on heat pipe solar collectors (mainly during the last decade), a comprehensive review which surveys and summarizes those studies and identifies the research gaps in this field has not been published to date. This review paper provides an overview of the recent studies on heat pipe solar collectors (HPSCs), their utilization in different domestic, industrial, and innovative applications, challenges, and future research potentials. The concept and principles of HPSCs are first introduced and a review of the previous studies to improve both energy efficiency and cost effectiveness of these collectors is presented. Moreover, a concise section is dedicated to mathematical modeling to demonstrate suitable methods for simulating the performance of HPSCs. Also, the latest applications of HPSCs in water heating, desalination, space heating, and electricity generation systems are reviewed, and finally, some recommendations for future research directions, regarding both development and new applications, are made.
