Ductless: https://www.youtube.com/watch?v=DzVJiSQNbew 需2.5-3"孔鑽出線,240V外牆開關,flare工具,由粗管維修口抽空側漏,然後打開高低壓閥。高壓可能無維修口。https://www.youtube.com/watch?v=JQkth-AM5CE
最好的窗式空調:美的U型僅42db,帶安裝架等附件,適合上開式Single Hung窗戶並允許窗戶大體上全開:https://www.amazon.com/Midea-Inverter-Conditioner-Flexibility-Installation/dp/B0866Y33PL/ref=sr_1_18?th=1? 10KBTU價格最低$330,12KBTU漲了 $30。安裝:https://www.youtube.com/watch?v=hux4BEKiu6k 開口22-36x13.75" 因此split/ductless似乎沒啥吸引力了。如果是側拉窗戶,建議靠邊安裝,上空處用隔熱泡沫用半開的窗扇夾住,窗開19.17";此時安裝U架固定螺絲不是半寸兩端而是1寸往下。 Walmart可購買3-4年保險,客服:ex_megan.k@partner.midea.com
類似的是Bestbuy旗下Insignia,尺寸19.2x13.5x22,用R32-可燃:https://www.bestbuy.com/site/insignia-350-sq-ft-8000-btu-u-shaped-window-air-conditioner-white/6480317.p?skuId=6480317
如果是側開Casement窗戶,隻好把窗扇卸掉,另DIY矮點的窗扇。窗式空調要往外斜下3度以便排水。例如窗扇20.75x52.75,就可以用上述U型空調。

窗式空調改回收機:去除冷凝器evaporator,其高低壓管分別接冷媒罐和輸入,兩者均為R410a接頭,輸入再加可換濾器。輸入端需欠壓開關在2~5psi時切斷電源。

上述Midea空調不帶製熱。
Mr Cool國產名牌:https://pdf.lowes.com/productdocuments/ee4eb5f2-4282-4b22-99c3-ec26fb0873a1/65949004.pdf 3-4ton均可用8/2線,管道是預充冷媒的,加長時要加接頭適配器,長度不超過73.8',總長限為221.5'。水泥墊可為36x20",左後各留12"右邊24"。
