An Experimental and Analytical Study of a Radiative Cooling System with Flat Plate Collectors
Open accessAbstract
A nocturnal radiative cooling system with flat plate solar collectors in Beijing, is assessed both experimentally and numerically. A cooling loop, including a radiator, a storage tank, pump, radiant floor and connecting pipes has been studied experimentally. The heat loss of an uncovered night-sky radiator was analysed according to radiation and convection theory. The water is circulated through the flat-plate radiator having 2 m2 of collector area at night to be cooled by convection and radiation to sky. The results indicate that the minimum temperature of the floor surface is 19.5 °C. Vertical temperature field is uniform. Design temperature can increase 1 °C compared with conventional heat convection. The average net cooling reached 26 W/m2, as condensation does not occur. It is possible to increase the total cooling capacity while maintaining a low pressure drop. It demonstrates the feasibility of cooling using fluid medium through nocturnal radiation.

When using sky radiative cooling actively, parameters such as the flow rate of the heat storage medium can be controlled, allowing higher exploitation (higher recovery speed), especially during periods when the potential is high.
“Furthermore, when using the technology actively, parameters such as the flow rate of the heat storage medium can be controlled [220,221,223,229], allowing higher exploitation (higher recovery speed), especially during periods when the potential is high, thus using the available resources in a timely manner.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
