Experimental study of a solar water heater with a heating vapor-dynamic circuit
https://doi.org/10.15518/isjaee.2025.09.029-042
Abstract
This study proposes a new technology for increasing the efficiency of solar water heating systems using a heating vapor dynamic circuit. The variant of assimilation of solar energy and transfer of the obtained heat into the volume of heated water is considered based on the application of the paradynamic effect, the essence of which is the use of a heating circuit, partially (20-30% of the circuit volume) filled with a low-boiling liquid (ELF), the vapors of which enter the heat exchanger-condenser located in the tank-pool with heated water. The results of the analysis of the efficiency of a number of CALs are presented, which made it possible to select the optimal low-boiling coolants. The efficiency of water heating systems with a vapor-dynamic circuit was experimentally investigated, which showed a significant increase in water temperature in the daytime cycle when gasoline and acetone were used as an intermediate circuit. It is shown that the proposed technological scheme of water heating using a vapor-dynamic circuit with a low-boiling coolant allows for effective heat transfer without the use of pumping equipment using solar collectors of the simplest type, which reduces the cost and operating costs of the solar water heating installation.
