任何形式水冷風機响香港根本就唔應該用。 首先係呢種裝置容易散播退伍軍人病毒,响政府"預防退伍軍人病工作守則"寫得好清楚,"Under all circumstances, the first option to be considered is to avoid, where reasonably practicable, the use of equipment which can create a spray of contaminated water", 此其一; 你唔係開屋企個水喉就可以將水務署嘅水用响制冷或加濕用途,要咁做的話係要特別申請。簡單嚟講灌啲水落水冷風機作降溫用途就係犯法,見第104章水務設施條例;及水務署"水務署裝置手冊" "Water supply shall not be used for any heating, cooling or humidification purposes except with the approval of the Water Authority.", 此其二; 降低一、兩度顯熱溫度(sensible heat)換嚟濕度大增,係遠離Thermal Comfort Zone做法,即係就多數人而言,開呢啲水冷風機係唔會感到舒適咗,此其三; 其實逆向諗下都知,呢啲嘢如果真係咁有效,人地仲洗乜花咁多錢去裝中央冷氣?
