室內和室外機之間較長的製冷劑管線會影響交流電性能並導致更高的電費嗎?

作為地下室裝修的一部分,我將HVAC室內機移動了約30英尺,這意味著製冷劑管線必須延長至隱藏在地下室天花板內的相同長度。

現在,我還可以選擇移動室外機,使其更靠近室內機的新位置。但是,這涉及額外的費用。我試圖找出這筆額外費用是否值得移動室外機。

較長的製冷劑管線會影響AC性能嗎?與使室外機更靠近室內機相比,我會產生更高的水電費嗎?

我的猜測是,由於冷卻液行進的距離較長,可能會損失更多的能量,從而導致房屋內的製冷量減少,從而導致AC裝置工作更加困難。

Each manufacturer has installation recommendations for their equipment, including distance, vertical height difference, size of line, etc. I’d follow their directions.

30’ does not seem unreasonable for total length, including distance plus height. See Trane’s installation guide starting on page 18-21.

Obviously when you push the limits of their recommendations, the efficiency will go down.
