Abstract
The invention provides a circulating water anti-freezing system for a solar heat collector, which relates to a solar circulating water system. The invention solves the problem that when the current solar circulating water system is operated in winter, heat tapes need to be additionally arranged on outdoor pipelines or anti-freezing fluid needs to be filled into the system, thus the operation energy consumption and cost of the system are higher, and the heat exchange efficiency is low. An input end of a first pipeline is connected with an insulating water tank; a first valve, a circulating pump, a second valve and a third valve are successively arranged on the first pipeline from the input end to the output end of the first pipeline; one end of a fourth pipeline is connected with a return water pipe on the plate solar heat collector and the other end is communicated with the insulating water tank; an air inlet and outlet pipe is arranged on the return water pipe of the plate solar heat collector, and the other end is communicated with atmosphere; the inner diameter of the fourth pipeline is the same as the inner diameters of the return water pipe and a water supply pipe in the plate solar heat collector; and the inner diameters of the first pipeline, the second pipeline and the third pipeline are smaller than the inner diameter of the fourth pipeline. The invention is suitable for use in winter in the north.
