Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
A kind of solar energy collector system, as shown in Figure 1, described system comprises heat collector 1, storage heater 2 and radiator 3, valve 4, valve 5, valve 18, temperature sensor 6, described heat collector 1 is communicated with storage heater 2 and forms closed circuit, heat collector 1 is communicated with radiator 3 and forms closed circuit, the pipeline at storage heater 2 and radiator 3 place is in parallel, heat collector 1 absorbs solar energy, water in heating heat collector 1, water after heating enters storage heater 2 and radiator 3 respectively by outlet pipeline 8, heat exchange is carried out in storage heater 2, by heat storage in the heat-storing material of storage heater 2, heat exchange is carried out in radiator 3, the water flowed out in storage heater 2 and in radiator 3 carries out heat exchange entering in heat collector 1 through water return pipeline 17.
In said system, by solar energy while carrying out accumulation of heat to storage heater, radiator can be utilized outwards to dispel the heat.Certainly, storage heater and radiator can independent operatings, or isolated operation one of them.
As shown in Figure 1, valve 4 is arranged on outlet pipe, for controlling the total water yield entering storage heater 2 and radiator 3, valve 5 is arranged on the position of the inlet tube 16 of the pipeline at radiator 3 place, for controlling the flow of the water entering radiator 3, valve 18 is arranged on the position of the inlet tube 7 of the pipeline at storage heater 2 place, for controlling the flow of the water entering storage heater 2, temperature sensor 6 is arranged on the position of the entrance of radiator 3, for measuring the temperature of the water entering radiator 3.Described system also comprises central controller, and described central controller and valve 4, valve 5, valve 18, temperature sensor 6 carry out data cube computation.
Preferably, when the temperature that temperature sensor 6 is measured lower than certain temperature time, central controller controls valve 5 strengthens aperture, and simultaneously by-pass valve control 18 reduces aperture, to strengthen the flow of the hot water entering radiator 3 to strengthen heat dissipation capacity.When the temperature that temperature sensor 6 is measured higher than certain temperature time, central controller controls valve 5 reduces aperture, and simultaneously by-pass valve control 18 strengthens aperture, to reduce the flow of the hot water entering radiator 3 to strengthen heat dissipation capacity.
When temperature sensor 6 measure temperature low to a certain extent time, the ability of the now external heat exchange of radiator can be deteriorated, normal heating demands cannot be met, this shows that the thermal-arrest ability of solar thermal collector also goes wrong, such as sunshine is not now very strong, or when there is no the sun evening, now valve 4 can be closed automatically, valve 5 and valve 18 can be opened completely, the pipeline at storage heater and radiator place forms a circulation line, water enters in storage heater the heat absorbing and store in storage heater, and the water of heating enters in radiator 3 and dispels the heat.
By above-mentioned operation, can when sunray be strong, meeting the heat-sinking capability of radiator 3, namely after meeting user's radiating requirements, unnecessary heat is stored by storage heater 2, when solar thermal collector 1 heat capacity deficiency, the heat in storage heater 2 is made full use of, to meet the radiating requirements of radiator 3.Can solar energy be made full use of like this, avoid the waste of too much heat.
As preferably, the temperature of the water entered in radiator 3 can not be utilized automatically to control the flow of water, the environment temperature measuring radiator periphery can be adopted, such as, the indoor temperature (by arranging indoor temperature transmitter) measuring radiator controls the flow of the water entering radiator automatically, if indoor temperature is too low, then increases the flow entering the water of radiator 3, if indoor temperature is too high, then reduce the flow entering the water of radiator 3.
Certainly, the prerequisite being controlled flow by indoor temperature is that the temperature that temperature sensor 6 is measured needs higher than uniform temperature, otherwise time the thermal-arrest of solar thermal collector is less able, in any case increase flow, radiating effect all can not be fine.
When the pipeline at storage heater and radiator place forms a circulation line, when temperature sensor 6 measure temperature lower than certain temperature time, central controller controls valve 5 strengthens aperture, by-pass valve control 18 strengthens aperture, to strengthen the flow of the hot water entering radiator 3 to strengthen heat dissipation capacity simultaneously.When the temperature that temperature sensor 6 is measured higher than certain temperature time, central controller controls valve 5 reduces aperture, and simultaneously by-pass valve control 18 reduces aperture, to reduce the flow of the hot water entering radiator 3 to strengthen heat dissipation capacity.The aperture of valve 5 and 15 is now consistent.
By such control, can the heat of Appropriate application storage heater, avoid the loss of heat.
