Abstract

The invention provides a frozen-blocking prevention solar natural ventilation system used for room heating and solving the problems of frozen blocking in winter and switch-over of a heat source. The solar natural ventilation system comprises a solar water heater, an auxiliary heating device, a first water pump, a second water pump, a controller, a floor heating cooling water pipe, a three-way valve and a return valve, wherein a water outlet of the solar water heater is connected with a first input end of the three-way valve through the first water pump; a water outlet of the auxiliary heating device is connected with a second input end of the three-way valve through the second water pump, and an output end of the three-way valve is connected with a water inlet end of the floor heating cooling water pipe; a water outlet end of the floor heating cooling water pipe is connected with the water inlet of the solar water heater and a water inlet of the auxiliary heating device through independent pipes; a water outlet of the first water pump is connected with a water inlet of the solar water heater through a water return valve; and the first water pump, the second water pump, the three-way valve and the water return valve are respectively connected with the controller and are controlled by the controller.

Description

technical field

[0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a solar floor heating system capable of resisting freezing and blocking. Background technique

[0002] The earth's solar energy is rich in resources, which can be used for free, without transportation, and without any pollution to the environment. Therefore, it is a popular energy source and represents the trend of future energy sources. Many places are now starting to use solar energy to heat hot water and use it in underfloor heating systems that use solar energy to heat rooms.

[0003] However, in the northern part of our country, the winter is relatively cold. If the floor heating system is not used for a long time, the outlet pipe of the solar water heater may be blocked by freezing, making the solar water heater and the entire floor heating system unusable.

[0004] In addition, at night, if you continue to use solar water heaters to he...
