標題: rc 是否用一開三冷氣機? [打印本頁]

作者: wychan 時間: 2003-9-15 21:13:38 標題: rc 是否用一開三冷氣機?

我係server臨終前出了個post想問下有關冷氣機的問題。現在再問一次吧.

我最近從相中及實地觀察發現細單位只有在細房的窗台頂上安了分體冷氣的室外部份。但按照contract寫應該有三部冷氣。這是否意味這一部室外部份同時供應三個室內出風口?這並不是三部冷氣機而係一部而已...

據我朋友的經驗，如果是一開二或一開三的機種，其總匹數一定很大，例如房是一匹，廳是兩匹，則室外部份要有五匹的力量。但是在晚上一般只會用房機。這樣比只是開一匹機的電費是多很多!!

ray 或其他工程界人士，這會不會呢?

唔會呀麻，上次我地去都好似記得，每單位出面眼見都有起馬兩部壓縮器的

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.

唔係喎.... 所有單位所廳及主人房的窗台都冇喎.....

你拿d相出來睇清楚d. 同時如果會遲d安上去的話，至少而家會見到d類似猪腸的物體，但是現在什麼都沒有.... :?:

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.

睇下售樓書有無寫明
不過你可以諗下one unit several machines會好貴

Flat with 3 rooms will has 4 air-conditioners
If all are connecting to the same outlet there will be lengthy hidden pipes.
:em20:

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.

唔會掛我依家屋企用一拖二部散熱都頗為大部 RC 外果部細好多下唔通科技真係發展得咁快!!!

作者: Ho and Serene 時間: 2003-10-27 14:59:37

我睇來睇去都係見到兩房單位都係得一部壓縮機請問有冇人跟進到知道另外一部放係邊道呀? :?: :?: :?: :?:

作者: wicyh 時間: 2003-10-27 15:11:01

一開三一眼睇哂

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

thanks

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....

只得 9200 BTU ??
我個剛收樓朋友個單位(昇xx 68? sqft) 個廳都 2xxxx BTU.

知唔知個壓縮機幾多匹?

作者: hales 時間: 2003-11-3 19:34:40

應該唔會一匹機阿...
前文所講果部只係一拖二
一拖三既話如果匹數少意味著....廳同房唔可以同時用機否則...唔夠凍..

作者: leebrian 時間: 2003-11-4 00:22:29

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?

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。

另外，我本來都驚如果開晒咁多部冷氣會唔夠涷，佢話而家RC 用嘅匹數足夠應付所有機開晒，原來之前RC自己試過喺夏天開行所有機，冷氣都夠涷，所以應該唔駛擔心。

我嗰friend重話RC用東芝呢個system係好先進，其他好多大發展商都會陸續轉用喎。見RC 嘅嘢都有板有眼，我哋都係第一次做業主，但覺得應該對RC要有信心。

作者: Agnes Henry 時間: 2003-11-8 11:42:59

yeah...... 我buy呢句..."通常喺豪宅先用"

同我朋友話"有錢人先會咁裝".....

rc... 掂!

呵呵呵!.. ^^

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:

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.
The most important is cool enough... :em11:
