Usually, the main aim of such storage technologies is to decrease the size of buffer tanks and domestic hot water (DHW) storage devices, to avoid the oversizing of HPs by reducing thermal peak loads and ON/OFF-cycles by shifting heating and cooling demands in time, to optimize the ...
When all the energy provided by the collector is required for water heating, or when there is not enough irradiance for working fluid evaporation, the valve (9) changes position so the fluid flows directly towards the condenser in the hot water tank, thus homogenizing pressure in the whole sys...
