Abstract :
A solar cooking system using vacuum-tube collectors with heat pipes containing a refrigerant as working fluid has
been fabricated, and its performance has been analysed experimentally. The experiments were conducted during clear
days in July and August of 2002 in Elazı g, Turkey under similar meteorological conditions for three refrigerants and
water. Detailed temperature distributions and their time dependences were measured. The maximum temperature
obtained in a pot containing 7 l of edible oil was 175 C. Also, the cooker was successfully used to cook several foods.
The cooking processes were performed with the cooker in 27–70 min periods.
