丟到google去找，找到這個.......
照這網頁說法是控制壓縮機維持在啟動狀態，那不就得把冷氣拆了改控制線路了？
感覺頗毫洨..........

B&Q特力屋冷氣達人表示，Airforce Air Smart節能器主要是在控制冷氣的啟動頻率，
而不是干擾電流。由於Air Smart冷氣節能器具恆溫系統，有「類變頻冷氣」的運作原
理，可使安裝後的冷氣如同變頻冷氣隨時讓壓縮機維持在啟動狀態，節省因壓縮機開開
關關間電力的浪費，花小錢即可大大省電。窗型與分離式皆可安裝，但冷房效果需小於
18000BTU以下，且為非變頻機種才能安裝。

一直保持在啟動，那不就越吹越冷？

對這個東西也感到蠻好奇的

****打那麼大...

來猜猜看原理：

如果不必拆機，那麼可能調整的大概就是電流/電壓/頻率/相位。

調相位應該省不了錢。調電流或電壓有點可能，關係到啟動電流和電壓，的確要看冷氣而定，與最多可降 3 成的能力來看還滿合理。頻率我就說不準了，不清楚冷氣馬達和電路與交流頻率有怎樣的關係。

要拆的話我是覺得比較不可能，這種作法滿危險的，電器公司可能不予保固。

不過上面寫說舊冷氣可能不能用，新冷氣可以用的機會較大，這點挺奇怪的。或許就是和壓縮機的啟動電壓電流等規格有關吧。

對了，安裝完畢不知道有沒有現場試驗證明省電的效果的確發生作用了？不然用戶光憑一個帳單要怎麼確定？冷氣用多一點就又沒省到了。如果有現場試驗，那是拿一般的實功瓦時計去測嗎？

而且照其他 search 來的資訊，30% 還真的是理想值，現在一台變頻的已經越來越便宜，花 2800 裝一個省不了太多電的東西我覺得不算很划算(能降低總用電量到較低價格計費區間，效果才夠大)。多半是摳門或是確有困難才會這樣考慮。

其實這邊有點詭異...

這套系統難道還有幫忙偵測溫度來調節強弱嗎 ?

還是只是一股腦的降低輸出功率 ? 這樣只會得到 "不怎麼冷的冷氣" 罷了.

原廠說明, 不過台灣的是否該廠製造存疑

How is an Air Conditioners size determined?

In accordance with Industry standards, dependent on geographic location, most Air Conditioning units are sized to extreme load conditions. Items considered are worst-case outdoor conditions, maximum internal heat loading, with a margin of safety added on. This result is then applied to the closest next size larger available air conditioning unit that is most often chosen for installation.


Therefore, except when conditions require maximum output, the majority of its hours of operation are spent operating with excess capacity; oversized for the duty it is performing, while wasting energy


裝設時為適應極端狀況,選擇的冷房能力常超出需求....
How does the Aircon Energy Saver adjust this overcapacity?

The Aircon Energy Saver turns the compressor off (largest electrical load) when its program senses overcapacity. (Saturated air unable to accept further cooling).
The air handler fan continues the cooling circulation. Upon sensing the calculated point that will maintain uninterrupted cooling the compressor is re introduced, thereby adjusting the output of the Air Conditioner to meet the demands of existing conditions and the set point of the thermostat, therein re-sizing the unit to meet demand. The result is a savings of energy without sacrificing comfort.

Why doesn㦙 the thermostat do the same job?

The thermostat maintains a temperature at which it is located, within certain tolerances, and cannot regulate the cooling applied to the area serviced by the Air Conditioner.

The oversized Air Conditioning system can quickly satisfy the thermostat set point. By rapidly satisfying the set point the system overshoots the set point.
Thermostat design set point allows for overshoot prior to switching the unit off. In many cases the short run time does not allow for proper dehumidification.

The Aircon Energy Saver modulates the output of the Air Conditioner in accordance with the demands of the area cooled so the overshoot of the thermostat set point is minimal while maintaining a more energy efficient cooling period.
避免過冷而浪費電...

照這說法，不就變成跳過冷氣本身控制電路去控制壓縮機？
滿好奇一個外加的東西有可能這樣做嗎？

還是覺得很懷疑
如果真的那麼有效申請個專利賣專利給冷氣大廠就賺翻了
還需要到B＆Q去賣
