is okay.

Normally is 5-8 l/s per person.

冇錯，不過我相信政府會以full load時的標準如70分貝做基準，換言之在t9還未完全運作時效果會更好..

以約數計算 100 sq ft 大約等於 10 sq meter
以一個600呎實用面續既單位計算
大約有 60 sq meter 樓底 9呎2吋計即係有275 cm 高
單位空氣體績約數為:
60 m2 x 275cm
= 60m x 1m x 275cm
= (6000 x 100 x 275) cm3
(1000 cm3 = 1 Litre)
then = [(6000 x 100 x 275) / 1000] Litre
= (6 x 100 x 275) Litre
= 165000 Litre

如果每秒 20Litre intake of flesh air
= (20 x 60 x 60) Litre/hour intake
= 72000 Litre/Hour intake

suppose唔會密封哂所有窗口抽風道等等i.e. 室內為一個open system
then 165000 / 72000 = 2.29
即係話室內每小時換氣 2.29次
以世衛既recommendation 隔離病房要求為每小時換氣10次.....
所以並不合乎隔離既要求....但我地又唔係被隔離所以如每小時換氣2.29次
已經足夠唔開窗都唔會好焗如果要計溫度既話......err.........................=.=
我Thermodynamic既書....掉哂好耐了.....有冇人可知道室內氣溫下降兩度係點計..>"<

正常又真係會做唔到....
我反而係最擔心一樣野就係假如室內空氣比吹出黎既空氣高既話
好易響出風口會有倒汗水....

你最初話入口處可以cool到16度，但現在只得兩度好似冇用，分分鐘仲嘖熱風

在夏天，一般室內比室外低三-四度，但是鮮風溫度只比室外溫度低兩度，那麼d風咪有熱風的感覺??

In normal PAU is set at 16 deg during Summer. This issue is putting the view of energy saving. However I guess 2 deg.c is insuccessful..

Now we don't know the design capacity so the max.load / capacity of PAU is also unknow.

Now the system seems a "fresh air with filtered only" hasn't fully treated meaning.

有冇人可知道室內氣溫下降兩度係點 => mc dt = mc x (t2-t1) = mc x 2

"以世衛既recommendation 隔離病房要求為每小時換氣10次"
which is different story in a office / guest room/bed room fresh air for each person is 5-8 l/s.

Air exchange means inject air from outdoor to indoor directly fresh air means treated outdoor air i.e. filtered dehumid and cooled /heated.

Air exhange rate is applied for toilet kitchen and special areas saying"隔離病"

Toilet = 8 air change per hr.
kitchen = 12 (I am not sure)
carpark =12

I think Air exchange Rate to be 72000:165000 = 1:0.44 i.e. less than 1
But the volume to be 165000 x 0.8 (net rate) = 132000
i.e. 0.54 times per hr

However if you put ON the fans the result of air exchange rate will be totally different…. Fresh air (not from PAU) will come from outdoor (window gap)….

How come 72000:165000 = 1:0.44 :?: :?:
72000 : 165000
= 72000 / 72000 : 165000 / 72000
= 1 : 2.29............. :?:
or you means 0.44 : 1 ?

不過你岩~我睇錯~
只係 0.54次....因為一次intake既volumw少於室內既total volume..

其實唔係咁計...係要分時段例如半夜要求會比較高
日間要求會比較鬆假如真係以70 db做standard 就一定會有
時間限制例如只能連續8小時等等...
不過我信EPD(因為我好多舊同學響EPD做..).....佢批得出黎問題亦不會太差

In think the system has not separated control for fresh air.

NO need to switch ON exhaust fan as fresh air will pressure out through door / window gap.
