According to described free-standing top water anti-freeze solar heat collection water storage system, it is characterized in that: the airtight valve that is communicated with on the described heat collector water supply line between described anti-freezing circulating pipe road and described heat storage water tank.
According to described free-standing top water anti-freeze solar heat collection water storage system, it is characterized in that: the airtight thermal-arrest circulating pump that is communicated with also on the described heat collector water supply line between described anti-freezing circulating pipe road and described heat storage water tank.
The utility model mainly for the hot water in hot water engineering heat storage water tank in the cold safeguard measure that night in winter, freezing prevention tubing was taked; avoid opening the energy waste that in pipeline cyclic process, huge thermal losses causes; can as far as possible thermal losses be reduced, and reduce user's power consumption.
Major measure of the present utility model is to make heat storage water tank and antifreeze circulating pump form alternate path, make it form the independent circulatory system, daytime heat collector thermal-arrest, pipe temperature and the heat storage water tank temperature difference set value higher than PLC controller, electric three passes valve events, thermal-arrest circulation pump, heat storage water tank, heat collector water supply line, heat collector water return pipeline and heat collector form heat collecting and circulating system, heat collector is collected hot water and is entered heat storage water tank, for user.
In the time that temperature in heat collector and the heat storage water tank temperature difference are not enough to start heat collecting and circulating system and pipeline water temperature lower than the antifreeze setting value of PLC controller, electric three passes valve events, antifreeze circulating pump is for electric operation, antifreeze circulating pump, heat collector water supply line, heat collector water return pipeline and heat collector form the antifreeze circulatory system, to prevent that pipeline from freezing.
The utility model is actually a kind of installation method, take near the position of heat storage water tank, one group of anti-freezing circulating pipe road to be installed at heat storage water tank turnover circulating line, and to adopt lower-powered water pump be antifreeze circulating pump, make itself and heat storage water tank form parallel system (equaling, to heat storage water tank, one group of by-pass line has been installed), adopt the recurrence relation between two groups of electric T-shaped valve controls itself and heat storage water tank, make heat storage water tank and anti-freezing circulating pipe road can not form path simultaneously.Daytime heat collector thermal-arrest, hot water is got back to heat storage water tank and is stored, the valve closing at heat storage water tank at night place, the antifreeze circulatory system is opened, and relies on antifreeze circulating pump that power is provided, and the water in pipeline is circulated, to avoid icing.The utility model is simple in structure, easy to operate, and reliability is high.
