Dribbling water from the system through the freeze valve causes warmer water to flow through the collector. Viability depends on water quality, maintenance of the freeze valve and correct installation. Water drained from the freeze valve must be routed and disposed of appropriately. Thermal Mass.
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.
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:
Freeze and overheat protection are critically important design considerations for solar water heating (SWH) systems. ICC-SRCC certifies and rates SWH systems under its OG-300 certification program, regardless of suitability for use in any specific climate (also known as climate appropriateness).
Based on these findings, to fill the knowledge gap this article presents the long-term results of thermal performance and anti-freeze protection of a solar heating system with heat pipe evacuated tube collectors with water as a solar thermal fluid. The operation of this system under real conditions was analysed for five years in southern Poland.
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;
