A novel anti-freezing strategy was proposed in this study to prevent freezing of the outdoor pipes based on the experimental solar system in Harbin, China. The practical operation results indicated that the strategy could meet the demands of freeze protection and exhibited improved economic performance compared to the conventional measures. The ...
In solar systems operating in moderate climate conditions, it is possible to use environmentally safe water without the addition of substances reducing the freezing point. It is then necessary to apply a solution that protects the system against the freezing of water. In the literature, several solutions can be found:
Passive solar-powered system could prevent freezing on airplanes, wind turbines, powerlines, and other surfaces. Images of a droplet on a surface show the process of freezing (top row), during which condensation temporarily forms on the outside of the droplet as it freezes.
Freeze protection measures prevent damage to the system due to the expansion of freezing transfer fluid. Drainback systems drain the transfer fluid from the system when the pump stops. Many indirect systems use antifreeze (e.g. propylene glycol) in the heat transfer fluid.
In the literature, several solutions can be found: automatic control system equipped with an anti-freeze protection (AFP) function which, by switching on the solar pump, allows for the transfer of heat from the heat storage to the SC;
In 2017, the lowest efficiency of the solar installation was achieved due to low DHW consumption in the building (especially during the summer) and the lack of support for the central heating system in winter. Table 3. Summary of annual solar installation results. 4. Conclusions
The anti-freeze protection system consumed annually from 7 to 13% of the heat generated by the collectors in the installation. Supporting the operation of the central heating system in the building during the winter season highly improved the efficiency of the solar collectors.
