Heat collector there is also mounted spare duct 8, is provided with valve, under normal circumstances valve closing in spare duct 8, when with water
When amount increases suddenly or heat collector 1 breaks down, close valve opening spare duct 8.Spare duct 8 is set, by spare duct 8
Supply water to user with the form of bypass, add the reliability of system work.
Terminate two pipelines on the heat collector 1 being connected with heat collection water tank 2 in each module to put in heat collection water tank 2, be used for
Realize Natural Circulation thermal-arrest: heat collector 1 absorbs solar energy makes the temperature of water in heat collector 1 higher than the water in heat collection water tank 2
Temperature, the proportion of the water in heat collector 1 is less than the proportion of water in heat collection water tank 2, and the water in heat collector 1 constantly rises to collect hot water
In case 2, the water in heat collection water tank 2 constantly flows downwardly in heat collector 1, and the temperature of the water in heat collection water tank 2 constantly raises.Use
Natural Circulation thermal-arrest, saves collection hot recycle pump, saves power, power consumption, reduces cost.
User installs a thermostatic valve for water end (W.E.), and one end of thermostatic valve connects tap water pipe line, and thermostatic valve detects water automatically
Temperature is also mixed by hot and cold water, so that user's water supply brings out coolant-temperature gage and keeps constant.Thermostatic valve is set, brings out water when user supplies water
When temperature is too high, make high-temperature-hot-water and cold water mix, it is to avoid user is burned because using high-temperature-hot-water.
Preferably, thermostatic valve is mechanical type thermostatic valve.
User family also installs ancillary heating equipment 7, when the temperature that water temperature needs less than user to system institute supplying hot water
Carry out post bake.Ancillary heating equipment 7 be commonly used in long-time sunlight irradiate insufficient in the case of use, use the time
Few, power consumption is little.
This utility model is not limited to above-mentioned embodiment, and it is any to above-mentioned embodiment that those skilled in the art are made
Conspicuously improved or change, all without the protection domain beyond design of the present utility model and claims.
