| [#1] 又係分體機問題 屋企要安裝二匹分體機： 1 大金是否最耐用最少麻煩? 2 舖頭話最好安裝冷暖機、價錢差10%左右。請問冷暖機是否耐用? 3 Inverter 係未好d? 謝謝! |

| [#3] 又係分體機問題 Last year, I boarded a kaito with brand new 30 units. Both were not cool at all even when hand placed at air outlet. Better entrust to the same supplier for installation to avoid controversy.Most units are inverted fed. |

| [#4] 又係分體機問題 舖頭係大金經銷商。屋苑大部份安裝都係佢地做。 希望手工OK。 我原本想用樂聲同剩係冷氣....... |

| [#6] 又係分體機問題 大金淨冷丶十多廿年丶非變頻 變頻丶十一丶二年丶多死電子板 冷喛就一定是變頻 最舒服是變頻 匹半室內 廿三db丶兩匹 三十二db、兩匹校率低好多丶一匹最高 大金有detail |

| [#8] 又係分體機問題 我咁耐都未換分體，就係身邊大多人遇到不良師傅， 無做足功夫去為每部分入氣，年半就唔凍，仲要係變頻嘅日立 |

| [#9] 又係分體機問題 我好多年前已經用變頻，真係無得輸，所以新裝修再用。 |

| [#10] 又係分體機問題 Depending on brand, below 5m refrigerant pipe, there is no need to add refrigerant. In fact, need to bleed off if less than 3 m. Not the more refrigerant the better only high current and not cool. I suspect problem lies with leakage due to flimsy mechanical strength of flared joints and high working pressure.(60% higher than R22) I used Nylog sealant at joint interior and Bondsteel at back of flared nut for better sealing and strength. |

| [#12] 又係分體機問題 我屋企用緊樂聲窗分兩匹淨冷機。感覺不及傳統分體冷氣。包括舒服度和寧靜度，有錯請指出。但聽師兄講變頻真係好好。但價錢就真係貴多多！ |

| [#13] 又係分體機問題 搭單一問：想問如果想在門頂過冷氣喉，高度有三吋，可行嗎？冷氣師傅是鑿吼還是core ？  |

| [#14] 又係分體機問題 我廳條喉就係穿門頂入房穿出外面. 果時裝修叫C父鑿定. |

| [#15] 又係分體機問題 用梗樂聲冷暖分體變頻, 感覺是寧靜亦很慳電, 但風量及角度調較範圍較窄, 新款機多數有同樣趨勢, 相信是要減低風阻避免倒汗水, 又有內置離子空氣清新, 總括來說是不俗, 不過手工好的裝機師父就很難找。 |

| [#17] 又係分體機問題 #12 Window split type is a freak, noisy due to weak concrete support when compared to mounting on external wall. Besides, no compartment for compressor alone for noise insulation. Usually, short run of refrigerant pipe. I diy installed a window split type. Only good for very small concrete opening where 420mm is not suitable. 50-70mm hole would be sufficient, by chiselling. Brick wall is easy. Industrial coring machine is huge using diamond cutter. Domestic one won't work. 最後修改時間: 2020-03-25 07:22:59 |

| [#18] 又係分體機問題 Most c fu's are lacking in tools, no tube bender/torque wrench/ammeter/digital thermometer, not talking about joint sealant. Don't expect high quality work, only fast installation using weakest material and go away asap. Today, I am going to check an 8 yo leakage unit with bad valve(can't be fully closed) using dye and uv light. Aged tube which can be brittle, my finding on another unit last week. Can simply release all R22 and install new tube, draw vacuum but not engineering work. Last time, frost bite, wish me good luck. 最後修改時間: 2020-03-25 07:46:04 |

| [#19] 又係分體機問題 50-70mm is for refrigerant pipe plus 20mm drain pipe. Can be a bit less for refrigerant pipes only, 6+10 mm pipes plus lagging for 1.5 hp inverter type. 6+12mm for fixed speed. Hard to fill a tube with dye without air lock. A syringe with long blunt needle would be better. Anyway, no sign of leakage as checked by uv light. Low suction can also be caused by clogged capillary tube(almost beyond repair) but current would be very high. High pressure when stopped, 140 psi R22, no obvious leakage. Indoor fan may be running low, hence icing in both refrigerant tubes at outdoor unit. Only plug or unplug gauge manifold tube when a/c running, viz 50-60 psi only, wear thick glove. Check again today, spare control card mislaid. Indoor fan Cap problem which is quite common. 最後修改時間: 2020-03-26 09:19:19 |

| [#20] 又係分體機問題 Beware, don't work on R410a by yourself. High conc of refrigerant+air intake+spark=explosion. Most importantly, as end-user, don't run the appliance when it's not cool at all.(can be leakage) https://kknews.cc/home/82z24oq.html "R410a製冷劑空氣混合氣體反應壓力超過15MPa，初始壓力達到 2.2MPa就可實現，並且反應的最高壓力可以達到30MPa，遠高於R22。同時，R410a運行壓 力也高於R22，可以達到4MPa 左右，因此R410a製冷劑發生爆 炸的危險性也高於R22。" 1MPa=10bar 原文網址：https://kknews.cc/home/82z24oq.html Problem with R32 A/C. Room cooler is probably OK due to sealed construction. https://kknews.cc/home/5oo2lo6.html 最後修改時間: 2020-04-26 08:02:01 |
