wally,
pls inform me first if u drop yr chiller, my wife has no say in this issue.講笑

補救方法: 盡量將chiller嘅熱氣帶走,不讓它回流返入風位(short circuit)係降低condensing temperature 嘅方法,試吓將１把普通家庭式細风扇吹走chiller排出的熱氣(小心吹風方向,如果唔係將熱氣壓返轉頭重big pan)即係多阻１把串連嘅booster fan.又平又簡單.
千祈唔好放chiller係柜內,百頁門都死
风扇要用風扇專用变速可變电阻,否則火燭有之.

我上星期在宏達買了4箱石每箱$800，每箱都超過50磅對比其他水族館是好經濟，平均$16磅而石上的石化鈣都好靚。而你有關分體水冷機的問題都可問他門，最好找祥哥問，因輿他吹水個多小時中學了很有關水族上的東西及其他事物。如你有空可找他吹吹水，不果他門要成貳叁點鐘先開門，最好先打電話有人至去。

宏達電話23967597，記得先電後去，我吃了多閉門羹了。

mark six,
你成日中六合彩架?成幾箱石,個缸咪好大?係唔係換缸呀?如果養珊瑚,有冇用滴流?講的经驗嚟聽吓,我而个缸得40L水養咗６絛鱼,嗰晚在宏達買咗幾件石同3磅珊瑚砂,嗰度的人都幾好傾,由清明節重新開缸,應該有3成成熟,你去<<圖片共享>>嘅其中...**缸頂滴流運行中**...就会見到我改裝马氏缸,俾啲意見啦,用緊Red Sea Prizm skimmer
遲啲開埋个190L馬氏缸改用假滴流,底缸加个水冷養多缸珊蝴,未玩過珊瑚,不過要自己鑽吼.點設計個假滴流用底缸呢? 主缸尺寸: 30''(W) x 30'' (H) x 13'' (D)

不是換缸都是初學者一個，個缸460L水左右。

jaffe, 唔知你有冇留意一般士多舖放置凍飲嘅雪櫃呢,指嘅係兩塊玻璃門窗互推後,取裡面飲品嗰種不透鋼凍櫃,佢上面嗰部制冷機,從外表睇嚟同日新CL-650都十分相似,而且行起上嚟仲好靜,但所散出嚟嘅熱氣唔知犀唔犀利,若然DIY佢加鈦炮造成水冷機從理論上可唔可行呢？

It is exactly what is using in 日新 chiller, but of course the horse power may be different. You can find it in many air-conditioning store, like 英光. That part called "Condensing Unit".

However, you need many tools to build the chiller:

1) If welding required, flush the tubing with dry nitrogen gas is recommend. This prevent oxidization at welding joint, and remove moisture which will react with refrigerant to become acidic.

2) You need a vacuum pump to evacuate the system after the condensing unit is connected to Titanium heat exchanger (鈦炮). This remove all air (nitrogen) in the tubing, and further remove moisture.

3) You need a charge meter to check the vacuum level, test leak (both under vacuum and under pressure) and filling of refrigerant.

4) You may need a clamp type meter to check the running current of the compressor. This can be used as a guidance for filling refrigerant.

5) Of course, you need refrigerant.

If you do not have those tools, especially vacuum pump which is expensive, you may consider to find local air-conditioning store to do the job for you.

wally兄, 我真係唔識英文架,剩係識得二十六個英文字母

因我自小見到英文就會人事正省

希望你能用中文表達,就下細佬幫一忙吧

I am sorry that I do not know Chinese Input Method, but find a website translater.

叫做 Condensing Unit, 当然马力也许不同。你能发现它在许多空调商店, 如英光

然而, 你需要许多工具修造:

1) 如果要焊接, 推荐用干燥氮气冲洗管材。这防止焊接位氧化, 和消除湿气(使冷冻剂变酸。

2) 焊接後你需要真空泵抽取消所有空气, 和进一步取消湿气。

3) 你需要 charge meter 检查真空水平, 测试浅漏(在真空之下和在压力下 ) 并且填装冷冻剂。

4) 你可用钳型 meter 检查压缩机的運作電流。这可用作填装冷冻剂的 guideline 。

5) 当然, 你需要冷冻剂。

如果你没有那些工具, 特别是是昂贵的的真空泵, 你可以考虑地方空调商店为你做。

Wally兄, 勞煩哂
