May be because of the machine running in part-load not at max.eff.
hoping the design is one outdoor unit for one in-door unit.[/quote]
如果唔係one outdoor unit for one in-door unit的話,有冇得嘈佢?作者: Ray 時間: 2003-9-15 21:24:54
one outdoor unit for 2 or 3 indoor units is also a normal design for office / comm. building.作者: diedsee 時間: 2003-9-15 22:24:33

Flat with 3 rooms will has 4 air-conditioners
If all are connecting to the same outlet there will be lengthy hidden pipes.

However consider the building materials for the hotel ... the chance for RC to have this kind of configuration is quite high作者: Ray 時間: 2003-9-16 18:52:06
Normally one outdoor is for one / two indoor units except special system "VRV". "VRV" will service for more units.作者: Agnes Henry 時間: 2003-9-16 20:06:22
I've asked official officer (Eng Dept) in show room. They confirmed that for 2flats units the air-con is 1 拖 3!!! They said that's a new technology so it's more power saving than the usual 1 拖 1 air-con. I am not sure is that true!!
Well I've also asked the Eng.Dept about the elect. saving label (tag) of this air-con but they've to check first and give me answer by next week wor. If that's not label one or two then we may have to pay more than the usual 1 拖 1 air-con!!!
Ray any follow up update from your friends?
Note: For 2Flats unit - 1.5 匹 for each room

hi wicyh
Could you please grouping the topics about 冷氣機 into one single thread?
thanks!作者: Ray 時間: 2003-11-2 17:04:59
I had checked the net but result in negative. Could you ask the officer to have a tech. data sheet?
If the COP is at a high level that means the machine will run in low energy Energy Saving....作者: wicyh 時間: 2003-11-2 19:59:18

sorry! I don't have authorization to do so.作者: stephenyeong 時間: 2003-11-3 13:25:27
I am so worry about the power consumption of the air-con. Anyone know that if I turn on the air-con for the small room only would it have the same power consumption for turn on all air-con. Any technician can ask this problem?作者: mc+sharon 時間: 2003-11-8 09:21:27
我識個機電friend 佢有行家喺在RC做冷氣,佢話RC用嘅係東芝叫做VRV system,係新product 嚟,屬於貴嘢,通常喺豪宅先用。我嗰friend話如果只係開一部冷氣,compressors 唔會fully 開晒個system會識自動proportion 番個耗電量。如果開晒所有冷氣,個system會自動開啟optimal power ,反而會比窗口機或舊式分體式慳電。佢仲話東芝而家攞梗一級能源標籤,如果攞到就証明呢個system係一級環保慳電。
VRV = Variable refrigerant volume system can provide much efficient operating base on the motor is running in variable speed.
And in case of fully speed operating the voltage of motor will run at 49.5Hz (normal is 50Hz) which resulting on electricity consumption of motor side will have around 6-8% saving in comparing with traditional.
However repair cost of VRV is higher than traditional units. :cry:作者: wicyh 時間: 2003-11-8 12:43:14
Actially Air-con is seldom need to repair. So don't worry about it.作者: Amy Poon 時間: 2003-11-8 13:20:31
Repairing cost should be higher for new & sofisticated system.
