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:
Does PCM flat-plate solar collector have antifreeze characteristics?
In this paper, Study on the PCM flat-plate solar collector with antifreeze characteristics has been conducted. A mathematical model with high precision for the daytime working and night freezing of the PA-FPSC system is present. The goal is to evaluate the daytime working and night antifreeze performance of the PA-FPSC system.
What is a freezing point device?
This is a small device that can determine the freezing point of propylene glycol solutions. When the system is operational, periodic testing of the glycol must be done to ensure that it is still suitable for use and providing the correct level of freeze protection. If a leak is to occur the system should be repair and recharged with glycol mixture.
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.
