“…The values of heating power/m2 collector area for the presented solar cooking system was able to reach the value of 500 W when the value of solar intensity was in the range of 900 to 1000 W/m2.The main advantage of the presented system was ability of the system to cook in the evening time. Haraksingh et al [15] experimentally investigated the solar cooking system using flat plate collector having dimensions of 1.83m x 0.91m as shown in figure 2. The volume of 22 litres of coconut oil was utilized as heat transfer fluid to heat up the immersed cooking pots by thermosyphon phenomenon.…”

Amid numerous sources of energy, solar energy possesses calibre to combat energy requisite for various sectors. A lot of significant research work has been carried out on solar energy to maximize its applications and efficiency of available designs. Among many applications, cooking is the one of the dominant application of solar energy. Other than basic design of box type solar cooker, solar collectors are employed in solar cooking system for the feasibility of more effective cooking. This manuscript inhibits various cooking system based on solar collectors like FPC(flat plate collector),ETC (evacuated tube collector),PDC(parabolic dish collector), PTC(parabolic trough collector), fresnel lens based collector and scheffler reflector type collector. Solar collectors based cooker designs render compatibility of cooking regarding cooking load, cost, cooking type, ease of operation and cooking time

“…A flat-plate collector natural convection solar cooker with short-term coconut oil TES, shown in Figure 14.10, was designed by Haraksingh et al (1996). Flat-plate indirect solar cookers, evacuated tube indirect solar cookers, and concentrating indirect solar cookers using SHTES have been designed, and a few of these designs are presented in this section.…”

“…On the other hand, ISC were observed more convenient than DSC. They provided high thermal energy without needing to change the cooker orientation, in addition, cooking can be performed indoors [9][10][11][12]. ISC was associated with plane reflectors to enhance the amount of solar radiation falling on the solar collector surface [13,14].…”

The aim of this work is to develop dual purposes solar heating system using heat pipe evacuated tube solar collector. The heat transfer fluid between the thermal loads and the solar collector loop was heating oil. The study provided two thermal loads; solar water heating system and solar baking/cooking system that had experimentally investigated under various weather conditions. The experimental pilot unit was installed in Solar Energy Department, National Research Centre, Giza, Egypt. Several test runs were performed to measure all assigned parameters that affect the system performance. The system is designed to provide high thermal energy through hot oil surrounding the inner vessel of the baker while the raw food can be baked/cooked and the outlet thermal energy can be used for heating water via immersed coil in the hot water storage tank; then the relatively cooled oil is returned to the solar collector via hot oil circulating pump. The water tank heat exchanger is designed with the following design parameters; specific heat of oil and water were 1.67 kJ/kg o C and 4.186 kJ/kg o C respectively; density of oil and water were 850 kg/m 3 and 1000 kg/m 3 respectively; mass flow rate of oil and water were 12 liters/min and 6 liters/min respectively. It is clear that the system in addition to provide thermal energy for baking/cooking unit, it can provide thermal energy for water heating purposes. The tested system can be positively contributed in baking and cooking purposes and providing hot water as well. It is found that, for the same flow rates of hot oil and water, as the hot oil temperature difference increased, the outlet hot water increased. The system is capable to produce hot water temperature up to 85 o C if the hot oil temperature difference was 100 o C while it can produce hot water temperature about 60 o C if the hot oil temperature difference was 60 o C during the day which is suitable for residential purposes and industrial process as well. Based on the resultant data, it is found that the system solar fraction was estimated as 54%. The auxiliary heating system can be electric source in case of using in urban areas and can be renewable energy source like biogas or hydrogen fuels in rural and isolated areas.
