“…The integrated collector does not require a water/PCM surface heat exchanger, but uses water/organic liquid (oil) as the heat exchanger; the method is shown in Figure 8. Chopra et al 45 have studied the PCM integrated manifold heat pipe vacuum tube solar collector system through experiments. In their method, when the mass flow is 24 LPH and heating at noon, the maximum thermal efficiency is about 72.52%, so the thermal performance of the solar collector affected by thermal stratification can be eliminated.…”

This article reviews the design of solar phase-change energy storage systems and their applications in residential buildings. The solar thermal collection system has high heat collection efficiency, no pollution, and it is also widely used in the field of building heating. In order to improve the efficiency of the solar collector system, the researchers found that integrating phase-change materials (PCMs) into the solar thermal collector system can achieve this goal, but there will be a problem of PCM leakage. Some researchers have solved this problem by microencapsulating PCMs, the thermal conductivity and energy storage efficiency of the PCMs after microencapsulation will be greatly affected. Adjusting the solar collector to an appropriate inclination angle can achieve the highest heat collection efficiency. Choosing the PCM in the appropriate temperature zone can improve the system efficiency. For the separated solar collector system, the parts that need to be considered include the type of heat exchanger, the structure of the energy storage heat exchanger, the shape of the heat exchanger fins, the type of solar collector, and so on. All in all, coupling PCM into the solar collector system can improve energy efficiency reduce carbon emissions and have good economics, the maximum internal rate of return of solar collectors integrated with PCMs in residential and industrial applications is 22% and 17.2%.

“…Various experimental studies have shown that integrating the phase change material (PCM) as TES provides hot water production for an extended period, minimizes the outlet temperature fluctuations, and reduces the thermal losses. So, the application of PCM with ETSC is beneficial [8,9].Wu et al, [10]developed a unique type SWH system that utilizes PCM and an oscillating HP to mitigate the effects of solar radiation intensity changes. It was demonstrated that the variation in collected efficiency with PCM is approximately 30% smaller than without PCM.…”

Solar water heating is the most promising way to effectively use solar energy among all other solar energy applications. In this study, an innovative way of incorporatingphase change material (PCM) between the annulusspace of the heat pipe and the evacuated tubes for solar water heaters (SWHs) is used. The proposed system can deliver hot water when demand is high/solar radiation is insufficient by using palmitic acid as PCM. The energetic and exergetic analysis of the developed systemintegrated with PCM is studied on both clear and cloudy days. The results revealed that the maximum daily collected useful energyfor the clear and cloudy days was10.65 MJ & 8.52MJ respectively, whereas the maximum storage tank temperature was found to be 46.2°C and 41.4°C for the corresponding days. The daily average energetic and exergetic efficiencies of the proposed system were found to be 76.57% and 79.64%, and 2.37% and 1.38%, respectively at a fixed mass flow ratefor clear and cloudy days conditions.The results reveal that the designed system eliminates the problem of overheating heat pipes and can supply hot water even under cloudy conditions.
