貯湯される。(Basic operation) First, the hot water temperature is set using the hot water temperature setting dial 15 of the controller 16. Next, the hot water sampling temperature setting dial 14 is used to set the temperature at which hot water is sampled using solar heat. When there is sufficient solar radiation, the hot water sampling temperature is set as (hot water supply temperature + heat radiation from piping and hot water storage tank 4). When the hot water temperature in the heat collector 2 reaches the hot water sampling set temperature, the first temperature sensor 7 detects this, and the hot water sampling solenoid valve 6 opens under the control of the controller 16, and the hot water collects with the cistern 1. Hot water at a set temperature is stored in a hot water storage tank 4 due to the head of the heater 2. When the temperature of the hot water in the heat collector 2 falls, the hot water sampling solenoid valve 6 is closed. By repeating the above steps, hot water is extracted and stored in the hot water storage tank 4.

ても少量の一定流量がある限りポンプ１２は作動
する。 When hot water is supplied and the hot water tap 24 is opened, the pressure switch 20 detects a pressure drop and the controller 16
The pump 12 is operated to supply hot water at a constant temperature. At the same time, the flow switch 22 detects the flow rate,
Even if the hot water tap 24 is turned off and the pressure switch 20 is stopped, the pump 12 continues to operate as long as there is a small constant flow rate.

弁６が閉弁し補給停止となる。(Make-up water) When hot water is not sampled due to insufficient solar radiation, or when the amount of hot water supplied is large and the amount of hot water stored is insufficient, the water level sensor 9 detects the L2 level and the temperature inside the heat collector 2 does not change. The hot water sampling solenoid valve 6 opens and hot water is replenished into the hot water storage tank 4. When the L3 level is detected, the hot water sampling solenoid valve 6 closes and the replenishment is stopped.

１１が停止する。(Auxiliary heat source operation) When replenishment begins and the hot water temperature in the hot water storage tank 4 falls below the hot water supply setting temperature, the circulation solenoid valve 13 opens and the pump 1
2 is operated, the auxiliary heat source 11 is operated, and the hot water storage tank 4 is operated.
The hot water inside is circulated through the circulation piping 10 and the auxiliary heat source 11 to raise its temperature, and when it reaches the hot water supply set temperature, the pump 12 is stopped, the circulation solenoid valve 13 is closed, and the auxiliary heat source 11 is stopped.

この場合、採湯設定温度が給湯設定温度より低い
場合には、前記と同様に補助熱源１１およびポン
プ１２を働かせて給湯温度を維持する。 In winter or when sunlight is weak, heat extraction efficiency can be improved by lowering the hot water sampling temperature setting.
In this case, if the set temperature for hot water sampling is lower than the set temperature for hot water supply, the auxiliary heat source 11 and pump 12 are activated to maintain the hot water supply temperature in the same way as described above.
また貯湯槽４での放熱により槽内の湯温が給湯
設定温度より低下した場合には、同様に補助熱源
１１を含む循環路での循環により給湯温度維持が
はかられる。 Furthermore, when the temperature of the hot water in the tank falls below the set temperature for hot water supply due to heat dissipation in the hot water storage tank 4, the hot water temperature is similarly maintained by circulation in the circulation path including the auxiliary heat source 11.

分の湯が排水される。(Preventing excessive temperature rise to stop overflow) When the amount of hot water drawn is large and the hot water storage tank 4 is full, the water level sensor 9 detects the L5 level, the hot water sampling solenoid valve 6 closes, and the hot water sampling is stopped. As a safety measure, overflow drain pipe 1 has a drain outlet located above the L5 level.
At step 8, excess hot water is pumped up from the lower layer of the hot water tank 4 and drained.

貯湯されることになる。したがつて満量状態より
少量ずつ給湯が行なわれると、常に高温水が貯湯
槽４に採湯され貯湯槽４内の湯温が給湯設定温度
より高温となつてしまう。 If there is still sunlight, the hot water in the heat collector 2 will be at a high temperature because the hot water sampling solenoid valve 6 is closed. If hot water is supplied at this time, hot water with a higher temperature than the set temperature will be stored. Therefore, if hot water is supplied in smaller quantities than in the full state, high-temperature water will always be drawn into the hot water storage tank 4, and the temperature of the hot water in the hot water storage tank 4 will become higher than the set temperature for hot water supply.

前記採湯電磁弁６が水位のL4レベル低下まで閉
弁して、この間採湯を停止する。L4〜L5レベル
の水量は、集熱器２内全水量の数倍とする。 In order to prevent this excessive temperature rise, if there is a lot of solar radiation and it is expected that the temperature will rise excessively, the excessive temperature rise prevention switch 27 is turned on. In response to this command, the hot water sampling solenoid valve 6 is closed until the water level drops to L4 level, and hot water sampling is stopped during this time. The amount of water at the L4 to L5 level is several times the total amount of water in the heat collector 2.
L4レベルまで水位が下がると採湯が再開さ
れ、集熱器２内の高温水が１回分投入される。し
かしその後の採湯は定温で採湯され、１時的な高
温水の投入によりわずかな昇温はまぬがれないが
異常高温の防止ははかられる。 When the water level drops to the L 4 level, hot water extraction is restarted and one dose of high-temperature water in the heat collector 2 is added. However, after that, hot water is drawn at a constant temperature, and although a slight temperature rise cannot be avoided by temporarily adding high-temperature water, abnormally high temperatures can be prevented.

成として、前記集熱器２と貯湯槽４との間に前記
採湯管３とは別に強制採湯用バイパス路を設け
て、制御器１６からの指令によりこの強制採湯用
バイパス路を開放するようにしてもよい。 In the above embodiment, the hot water sampling pipe 3 is installed between the heat collector 2 and the hot water storage tank 4 as a configuration in which hot water is forcibly drawn when the hot water temperature in the heat collector 2 does not reach the hot water sampling set temperature. Separately, a bypass path for forced hot water sampling may be provided, and this bypass path for forced hot water sampling may be opened by a command from the controller 16.

い。 First, efficient hot water collection is possible because the solar heat collection method uses a constant temperature hot water collection method, and the hot water collection temperature can be set variably depending on solar radiation, season, hot water use temperature, etc. For example, when there is sufficient solar radiation, the hot water sampling temperature is set to a temperature that adds the temperature drop due to heat radiation in the piping and hot water storage tank 4 to the general hot water supply temperature (around 40° C.). Compared to the natural circulation and forced circulation systems, the temperature of the water supplied to the heat collector 2 is always low, and the hot water sampling temperature is close to the operating temperature and is not high, so the heat collection efficiency is better than the other systems.

負荷がある場合に対応ができない。 In addition, the hot water sampling temperature can be set to the operating temperature from the initial state, making a large contribution when there is a hot water supply load in the morning and daytime. On the other hand, in the natural circulation and forced circulation methods, the temperature of the entire hot water storage tank is raised, so the usable temperature is reached in the afternoon, and cannot be used when there is a hot water supply load starting in the morning.

湯温が維持され使い勝手が良い。 Furthermore, in winter or in cases of insufficient sunlight, the hot water temperature setting is variable, making it possible to efficiently draw hot water at a low temperature. In this case, the auxiliary heat source 11, the circulation pipe 10, the pump 12, the circulation solenoid valve 13, and the second temperature sensor 8 maintain the temperature of the hot water in the hot water storage tank 4 at the hot water supply setting temperature, making it convenient to use.
