今回の屋根冷却に関して Commenting on the roof cooling

今年の暑さで何か暑さ対策を考えないといけないと思い。屋根に散水を考えた。しかし庭の水まきホースでは・・・・・・
いろいろ考えたところ、冬に歩く場所に雪消しようの山型のホースを思い出した。これは今まで冬にしか用を足さないものと考えていたが、散水。。。。。。均一に！！ぴぴーっと来たものです。
早速対応を
本来エンジニアなので、まずはデータを屋根の

• 温度は？
• 勾配は？
• 散水量は？
• 予想温度変化は？

これが仕事なら、こうしますが、実際自分の家ですからそく対処、即効果を考えないといけない。
夕方、4時ごろ、車庫からホースを引っ張り出して屋根に出してみた。
とりあえず多めに水を撒いてみたところ、この時期外が、34度を超えると、居間の気温は、冷房をかけないと32度程度になる。
これが30度程度となり、体感－１～２度の効果は期待できそうである。

水は、井戸水なので電気代のみですからただとは言わないが、安いものでもだし過ぎも考え物
最適は、雨どいに届く程度蒸発する水量！　
井戸のポンプは、カワモトのインバーターポンプNF2-250SKなので揚程も2階までならOK何とか使えそうです。あまり水を出すと台所で使えなうなるのでほどほどに。。

さらに、早急に（当座手動なので）屋根に散水したい場合もある。
来年にかけて、これらのマイコン制御を検討する
できれば温度計測。流量計測時間日照により散水制御、それを家庭内オンライン制御　できればクラウドコントロール
できるか！　　な

Commenting on the roof cooling
I do not think I have to think of something heat measures in this year's heat. Considering the watering on the roof. However, in the garden of a watering hose ......
I was thinking variety, snow in place to walk in the winter of extinguishing try mountain type of hose remembered. Although this was considered to be not added together to use only in the winter until now, watering. . . . . . Uniform! ! Thing came Pipitto.
Immediately the correspondence
because the original engineer, first the data of the roof

Temperature?
The gradient?
Watering amount?
Expected change in temperature?

If this is work, and this is, because it is actually your own home immediately deal, do and do not think the immediate effect.
Evening, around four o'clock, I tried out and pulled the hose from the garage to the roof.
When I tentatively larger amount of watering, this time out is more than 34 degrees, the temperature of the living room, is about 32 degrees and not put air conditioning.
This is approximately 30 degrees, the effect of the bodily sensation -1 to 2 ° is likely to be expected. Water is not saying that just because only electric bill because the well water, also Kangaemono also out too cheap thing water optimal, that evaporates extent reach to advance in the rain!　 Pump wells, inverter pump of Kawamoto NF2-250SK you could use if OK somehow to so head is also the second floor. Moderately so much made ​​now can use in the kitchen and put out the water. . In addition, as soon as possible (current manual of because) there is a case where you want to watering the roof. Over the next year, consider these microcomputer control temperature measurement if possible. Flow rate measurement time sunshine by watering control, it cloud control if you can home in on-line control you can! I
