- #26 [alexanderkoo], 22-08-14 07:04Only got one point, choose fixed speed split unit when it's running continuously.(same for undersized AC, most likely due to cost, underestimated immense solar heat especially facing west and aging) Only watched the first few minutes.
Most brands are having inverter AC's but Gree offering a few models. This is marketing strategy to jack up the price, in fact, going back to era 70 when AC's were kind of extravagant items. Being fooled without noticing. But for commercial area with central plant of few hundred tons, inverter drive is a must for energy saving.
For example, selling point of R410a when compared to R22 was ozone depletion. The difference was only 6% quoted after discontinuation of R22 units

2022冷氣機購買指南/冷氣師父自已都唔知買咩好(粵語中文字幕)
觀看次數:10,668次 2022年7月12日 一年安裝不到三套分體機,談不上專家。只是受過專業訓練,對空氣調節有認識,碰上我要買機,順道分享一下。 - #23 [EF9], 22-08-11 17:19其實 能源標籤 計算,
同一牌子新機計, 變頻同定頻
一年 相差 $1500 左右…..
現實又唔同??
Thx - #22 [phil.ng], 22-08-11 15:44是 千二丶兩個月丶六百一個月丶不用估
- #21 [alexanderkoo], 22-08-11 15:42For inverter feeding ac compressor (as different from DC compressor now experienced), the principle is to vary both voltage and frequency such that V/F is a constant. But why, maintaining higher efficiency at varying operating point or heat load.(say solar heat during sunset) Apparently, there is energy saving under such circumstance but not that much as raved.
A fixed speed unit would still turn on and off to save energy but more noise and discomfort. Room acting as temperature buffer.
If both running at 50Hz continuously due to appliance sizing, the fixed speed one is more energy saving due to no inverter board loss.

- #19 [tst1800], 22-08-11 11:06有時講彩數
我 2005年新居, 因為親戚做工程, 當時 Toshiba 代理剛剛有特價比佢, 裝左分體 2, 1.5, 1匹 各 1部
無特別挑選過性能及規格, 十幾年來只洗過一次, 仍然健在.
夏天最高電費 / 兩個月約 $1400 ( 只有兩個人住)
因為搭棚換機要萬萬聲, 所以唔理佢啦, 打柴再算
我外母 1997年裝珍寶 2匹窗口機, 好嘈, 但仍健在, 好很凍. - #18 [alexanderkoo], 22-08-11 06:44Hard to make comparison in situ. Once people pay top dollar for the new AC, they would have biased mind that there must be energy saving, hence justifying themselves.(same for migration) Besides, would raise the temperature setpoint to save energy.
Can only be conducted in test lab. with same controlled conditions but any reports, practically none.

十一二年丶吾維修丶因個殻好殘(機底) - #16 [degalle], 22-08-11 00:14檢查維修分體若要搭/拆棚,慳埋d 電費睇怕要倒貼

變頻分體正統用上“ 大散熱機 ”
由於散熱量排放條件更好,
耗電量更低。 - #14 [呀金], 22-08-10 20:17因為一般暖爐直接用電發熱,而冷氣只是用電搬走熱力。
- #13 [dorman], 22-08-10 19:59暖爐電費比冷氣勁得多
- #12 [沉默的膏蟹], 22-08-10 17:53窗口機只要係搖控款,記得開多d機,唔制冷都開下風扇,因為面版有機會受潮令到部機失控。
- #11 [phil.ng], 22-08-10 17:40十一二年丶不修保養丶自己洗!!!
無有怕!
冬暖夏涼丶分體出暖氣比發熱線平約一半!這又慳 - #10 [twinggy], 22-08-10 17:39#7 又慳唔到咁多,因為有好多個月都唔使長開冷氣。
變頻窗口機襟唔襟用又真係未知數。 - #9 [phil.ng], 22-08-10 17:36大金 十一二年丶才換丶夠吾夠?
- #8 [peter188], 22-08-10 17:29以我所知,加雪種比以往舊雪種貴。
依家D電器易壞就一定。
