この発明は太陽熱集熱器と、放熱器と、これら両者間を
接続する管路内で熱媒体を循環させる循環装置を具える
太陽熱集熱システムに関するものである。Detailed Description of the Invention (a) Industrial Application Field This invention relates to a solar heat collector, a solar heat collector, a heat radiator, and a solar heat generator comprising a circulation device for circulating a heat medium in a pipe connecting the two. It concerns a heat collection system.

ていた。(B) Conventional technology Conventionally, in known solar heat collection systems having the above configuration, the signals of the high temperature sensor attached to the solar heat collector and the low temperature sensor attached near the radiator are generally different. When the high temperature sensor is 3°C to 7°C higher than the low temperature sensor, the circulating pump circulates the heat medium in the pipe connecting the two by using the ON output from the differential temperature control circuit. A control method using a differential temperature thermo system has been used in which when the circulating pump is activated and the differential temperature is lower than the above value, the ON output is cut off and the circulation pump is stopped.
また、近年では、太陽電池を利用して太陽電池の受熱日
射量が所定値以上の時に、直接この循環ポンプ動作させ
る方法も一部で用いられるようになっている。In recent years, a method has also been used in some cases in which a solar cell is used to directly operate the circulation pump when the amount of solar radiation received by the solar cell is greater than or equal to a predetermined value.
しかし、差温サーモ方式による方法では高温センサーが

していた。また、外気温の下がる冬期間は特に外気温の
影響を受は易く、太陽光があっても差温か検出できず、
循環ポンプが作動をしない場合もあるという欠点をもっ
ていた。However, with the differential temperature thermometry method, the high temperature sensor is affected by the outside temperature, and the circulation pump often operates due to the outside temperature regardless of sunlight, resulting in repeated malfunctions. In addition, during the winter when the outside temperature drops, it is particularly susceptible to the influence of the outside temperature, and even if there is sunlight, the difference in temperature cannot be detected.
The drawback was that the circulation pump sometimes did not work.

してしまうという問題点を有ｌ、ていた。Therefore, in order to solve the above problem, we researched a control method that uses solar cells and operates only when the amount of solar radiation exceeds a predetermined value. However, although this method solves the above-mentioned problems caused by the outside temperature, when the solar cell is directly connected to the DC relay or circulation pump in a circuit, there is an operating characteristic in which the operation end voltage is lower than the operation start voltage. Therefore, once the operation starts, it will not stop easily and may not be necessary.
In order to continue operating at L, there is a problem in that operating energy is wasted and the solar energy that has been collected is reversely radiated.

Fig. 1 is a diagram of the solar heat collection system of the present invention, where ■ is a solar heat collector, 2 is a radiator, and 3 is a solar heat collector. Pipe lines connecting the heating device 1 and the radiator 2, and reference numeral 4 denote circulation pumps for circulating the heat medium within the pipe line 3, respectively. In the embodiment shown in FIG. 1, a solar cell 5 is installed in approximately the same direction as the solar heat collector 1, and the output from this solar cell 5 is
Connect to the DC relay 7 in the control board 6 as shown in the figure,
When the solar cell 5 reaches a predetermined amount of solar radiation by adjusting the resistor R1 placed in parallel with the coil of the DC relay 7, a contact S2 operating in conjunction with the DC relay 7 sends an ON signal to the circulation pump 4. Exit L7 and start the solar heat collection system. However, if the circuit is simply left as is,
Due to the operating characteristics of the DC relay 7, the DC relay 7, which is turned ON at the operation start voltage, will not turn OFF until the operation end voltage is several volts lower than the operation start voltage. It will not stop unless the amount of solar radiation is considerably lower than the amount of solar radiation when the signal is issued, resulting in wasted operating energy and a phenomenon in which the solar heat that has been collected is radiated back.

陽熱集熱システムを完成する事が出来るようになる。For this reason, the inventor of the present invention will continue with further research.In order to be able to adjust the amount of solar radiation at the end of operation, the inventor of the present invention has developed a contact S that operates in conjunction with the DC relay 7 being turned ON at the operation start voltage.
By adding l and resistor R2 to the circuit, when the DC relay 7 is turned on, the load on the resistor R2 increases on the entire circuit, and the circulation pump 4 will stop if the radiation amount does not increase by this amount. The circulation pump can now be turned off at higher solar radiation levels than when R2 is not installed. -) A circuit that outputs a signal to turn on the circulation pump 4 when the solar cell 5 receives solar radiation exceeding a predetermined value by setting the resistance value of the resistor R1, and a circuit that outputs a signal to turn on the circulation pump 4 by setting the resistance value of the resistor R2. When the flow rate is less than a predetermined value, the circulation pump 4 is turned to O.
The circuit that outputs the signal to turn it into an FF is completed. These two circuits make it possible to complete a solar heat collection system that collects heat only when there is the necessary amount of effective heat collection solar radiation.
