... ambient conditions from December to April. The thermal efficiency of the EFPCs reaches a maximum value of 73.2%, with the glycol–water mixture as a heat transfer fluid at an inlet temperature of 31.2 °C, when the ambient temperature is 15.3 °C, average irradiance is 679.2 Wm −2 , and vacuum pressure is 20...

...-up solar field using the CL strategy allows us both operational autonomy and significant energy savings. Solar loop thermal and optical powers gained and lost are plotted for the typical days considered; we observe that maximum thermal efficiency of 66.53% is achieved at 2.27 p.m. for the summer day...

... to an annulus gas. The vacuum surrounding the evaporator removes the energy losses, thus for a 10 mm gap size, the energy losses, the Rayleigh number, and thermal efficiency evolve from (1279 W h, 9 × 10 6 , 55%) for an air-filled space to (466 W h, 15 × 10 6 , 71%) for an evacuated space.
