Abstract
ABSTRACT As one of the key indicators of the Organic Rankine cycle (ORC), it is of great significance to analyze power generation effectively and directly. Different from the traditional mechanical contact ORC system and in order to reduce the influence of component friction, unstable working conditions, and other factors on power generation analysis, this paper establishes the corresponding power generation model based on the maglev vortex rotor ORC system, and uses R245fa, R123, and R601 as working fluids to carry out relevant simulation and experiments. The simulation results are in accordance with the model calculation formula, and the differences between simulation results and the reference values are less than 0.45 kW (R245fa), 0.61 kW (R601), and 0.29 kW (R123), respectively, which are in line with the theoretical power generation of the maglev rotor ORC system. Furthermore, the experimental results show that under different variable conditions, the difference between the system power generation and the net output power is less than 0.1 kW, and the corresponding RMS and standard deviation are less than 0.1 and 0.05, respectively. Therefore, the maglev rotor ORC system can effectively reduce the influence of component friction loss, and its corresponding net output power and power generation are almost equal.
