View more6 FAQs about [The role of solar antifreeze system]
How important is anti-freeze protection?
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.
Can a PCM flat-plate solar collector system prevent freezing damage?
PCM flat-plate solar collector system with antifreeze This paper proposes a flat-plate solar collector system (FPSCs) with antifreeze characteristics which uses the phase change material (PCM) to store up a moderate amount of thermal energy during the daytime and release the energy during the night to prevent the FPSCs from freezing damage.
How to protect a solar system from freezing water?
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:
Are there devices that heat the installation components exposed to freezing water?
There are no devices that heat the installation components exposed to freezing of water, e.g., heating tapes. The operation of this system under real conditions was analysed for five years in a residential and retail building located near Kraków in Southern Poland.
How can a solar power system be adapted to a heat storage system?
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;
Does the solar thermal system work in a transitory climate?
This article presents several years of results of the solar thermal system’s operation in a moderate, transitory climate. Because water was used as a solar thermal fluid, the AFP system was applied. The operation of the HPETSCs was analysed from 2013 until 2017 in a residential and retail building located near Kraków, Poland.
