PAU和AHU是甚麼？

02/03/2017 RCPHK 工商舖投資

其實PAU同AHU兩者都是一台風櫃,
兩者都可以有冷卻和抽濕的功能分別是PAU是主要作用是抽室外的空氣處理
再駁去FAN COIL UNIT
為一些沒有能力處理鮮風設備/沒有鮮風供應的房間供應鮮風
保持空內氧氣水平
又因為要處理的空氣溫度和濕度都比較高
COOLING COIL要比較大AHU主要是抽出室內的空氣(return air)和部份鮮風
以控制出風溫度和風量來並維持室內溫度

要注意是VAV/CAV只是風櫃本身的風量會否改變
PAU不一定是CAV
(VAV PAU好多是用於有CO2 SENSRO的系統, 室內CO2量控制供鮮風量)
