The invention discloses an anti-freezing system for a water inlet and outlet pipe of a solar water heater and relates to the field of solar water heaters. The anti-freezing system comprises a digitalthermometer located in a through-wall position of the water inlet and outlet pipe of the solar water heater, a numerical value comparison module and a peristaltic pump mounted at connection of a linerof the solar water heater and the water inlet and outlet pipe. The numerical value comparison module is composed of two cascaded four-digit numerical value comparators. The digital thermometer is used for collecting water temperature in the water inlet and outlet pipe and sending the water temperature to the numerical value comparison module. The numerical value comparison module is used for outputting a working command of the peristaltic pump to control the peristaltic pump to work when the water temperature is lower than a set temperature value. The anti-freezing system has a function of controlling the temperature of the water inlet and outlet pipe of the solar water heater automatically, achieves micro water cycle in the pipe, realizes a purpose that the water temperature in the pipeis kept at a constant temperature and solves the problem that the water inlet and outlet pipe of the solar water heater is frozen to crack in winter and hot water cannot flow directly when the solar water heater is used every time.
Description
technical field [0001] The invention relates to the field of solar water heaters, in particular to an antifreeze system for inlet and outlet water pipes of solar water heaters. Background technique [0002] In the prior art, electric heating cables are wound on the outer wall of the inlet and outlet pipes of the solar water heater, then wrapped with thermal insulation material and fixed with aluminum foil tape, and continuous electric heating is required in winter to prevent the inlet and outlet pipes of the solar water heater from freezing and cracking . At present, the heating method of electric heating belt is used, and the disadvantages are that the power supply is not interrupted overnight, the power consumption is large, the heating efficiency is low, and there are potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide an antifreeze system for the inlet and outlet pipes of solar water heaters, which has the fu...
