Abstract
In the water tank of the solar water heater several water levels are set, the bottom portion of the water tank is equipped with a temp. sensor, a soft water-taking pipe whose head is equipped with a float ball is mounted on the barrel body of water tank bottom, in the original state of the water tank the water is retained at lowest level, when the water temp. is reached to set temp., the water can be charged into water tank from water tank bottom and reached to second tevel, at the moment, the water of water tank bottom is cold water and the water of its upper portion is hot water, and when the cold water of its bottom is heated to set temp., the water can be continuously charged into the water tank and reached to the third level, so that the water can be reached to highest level.
Description
Technical field:
The present invention relates to the solar water heater technology
Background technology:
At present solar water heating system is divided into two kinds of pressure-bearing type and non-bearing types.Pressure-bearing type solar hot water system water inlet pipe feeds water tank bottom, outlet pipe is drawn from tank top, water tank remains full water, water-filling specially, therefore simple, convenient, but at sunshine when relatively poor, the water in the water tank is difficult for reaching serviceability temperature, and water tank need bear 0.6Mpa pressure, causes cost to increase.
The shared pipe of non-pressure bearing system water inlet pipe and water outlet pipe feeds water tank bottom.When the water tank water-filling, can select different water levels, the control filled water amount.Then utilize drop that water is taken out during water intaking.Because water tank is pressure-bearing not, so cost is lower, but need, and the surplus hot water in the water tank can be mixed when charging into cold water cool often to the water tank water-filling, every day, filled water amount can't be adjusted according to the situation at sunshine on the same day, filled the corresponding overheated or not hot phenomenon of water temperature that causes of filling that I haven't seen you for ages more.
Summary of the invention:
The object of the invention provides the non-pressure-bearing control system of a kind of solar water to water tank constant temperature Water.Solved the problem that above-mentioned conventional system occurred.In the water tank of solar water heater, be provided with several water levels, be provided with a temperature sensor, be equipped with the soft intake pipe that a head has ball float on the water tank bottom stack shell at water tank bottom.Water remains on minimum water temperature in the reset condition water tank, when this coolant-temperature gage reaches design temperature, by water tank bottom to the water tank water-filling, stop until reaching second water level, this moment, water tank bottom was a cold water, and top is hot water, when the cold water of bottom is heated to design temperature, continuation stops until reaching the 3rd water level to the water tank water-filling, so goes on until reaching peak level.When water intaking, because the effect of water tank inner float ball pipe has guaranteed that the water that takes out is the hot water at top.Because the present invention is heated to design temperature step by step with cold water, therefore also can use hot water in cold season or when photoing badly day.And satisfying under the prerequisite of serviceability temperature, the thermal efficiency of solar thermal collection system is the highest.
Description of drawings (1) is a principle schematic of the present invention
The specific embodiment is shown in figure (1): the solar heat water control system has attemperater 1, heat collector 2, controller 3, magnetic valve 4, form, be provided with several water-level probes h1, h2 in the water tank ... H, water tank bottom are provided with a temperature sensor 5, are equipped with the soft intake pipe 6 that a head has ball float on the water tank bottom ladle body.Controller opens solenoid valve 4 when cistern water level is lower than lowest water level h1, running water enter water tank until reaching minimum water h1, and magnetic valve 4 cuts out.Sending signal controlling magnetic valve 4 by temperature sensor 5 to controller when water reaches design temperature in the water tank opens, water level enters from water tank bottom hot water is held up until reaching the second water level h2 closed electromagnetic valve from the beginning, this moment, water tank bottom was a cold water, the hot water that has been heated to design temperature in the above, through after a while, heat collector absorption solar energy is heated to design temperature with the cold water of water tank bottom, again to the water tank water-filling, reach the 3rd water level h3 until water level, closed electromagnetic valve, so go on, until reaching peak level.After reaching peak level, no matter how high water temperature is, all no longer to the water tank water-filling.Open valve 7 during heat-obtaining water,,, take out the hot water of water tank topmost all the time owing to the effect of ball float pipe 6 no matter the water tank middle water level wherein.
Claims (2)
1, a kind of heating of solar water heater and use control method are provided with several water levels in the water tank of this water heater, are provided with temperature sensor at water tank bottom, and the water tank stack shell is provided with the intake pipe that a head has ball float, and this method comprises the steps:
A) in the reset condition water tank, remain on the first minimum water level;
B) when the water temperature in the water tank reaches design temperature, by water tank bottom to the water tank water-filling, when reaching second water level, stop, this moment water tank bottom be cold water, top is hot water;
C) when the cold water of bottom is heated to design temperature, continue when reaching the 3rd water level, to stop to the water tank water-filling;
D) continue above-mentioned steps until reaching peak level, like this, when water intaking, because the effect of water tank inner float ball pipe has guaranteed that the water that takes out is the hot water at top.
2. according to the method for claim 1, it is characterized in that: controls such as water level tongue tube, electric contact, pressure sensor or ball float.
