Abstract

Combining theoretical analysis

a comparative experimental study on the performance of R141b micro heat pipe photovoltaic/photo-thermal （MHP-PV/T） system and acetone MHP-PV/T system was conducted under different installation inclinations

circulating water pump flow rates and other operating conditions in the summer of 2023. The photoelectricity

photothermal

and overall performance of R141b and acetone MHP-PV/T systems were analyzed. The results indicate that at a 40° inclination angle and an average ambient temperature of 30.2 °C

R141b micro heat pipes exhibit better heat transfer characteristics

resulting in superior thermoelectric co-generation performance of the R141b MHP-PV/T system. At this point

the average thermal power

average electrical power

average thermal efficiency

and average electrical efficiency of the R141b micro heat pipe PV/T are 321.9 W

118.9 W

35.2% and 12.9%

respectively

which is 51.9 W

54.7 W

6.5% and 5.6% higher than that of acetone MHP-PV/T respectively. In this study

the performance differences between R141b MHP-PV/T and acetone MHP-PV/T systems were compared

and it is found that R141b micro heat pipe has better heat transfer performance compared to acetone micro heat pipe

and the R141b MHP-PV/T system has better cogeneration performance. Compared with acetone

R141b is more suitable to act as the working fluids of the MHP-PV/T system.
