Primary renewable sources of high-temperature solar energy and low-temperature potential from outer space can be effectively used for both heating and hot water supply, as well as for cooling in passive radiation cooling systems. The developed combined-type collector for daytime heating and nighttime cooling of the heat carrier reduces the metal consumption and capital costs by half, as well as the occupied area of the structure, which is especially important in urban environments.
