規劃時中央空調應考(kao)慮冬季防凍(dong)(dong)(dong)問(wen)題，防凍(dong)(dong)(dong)手法建(jian)議(yi)運用(yong)熱水，不支持運用(yong)蒸(zheng)汽(qi)和(he)電(dian)(dian)加熱。蒸(zheng)汽(qi)防凍(dong)(dong)(dong)也(ye)能(neng)夠，可是簡略呈現(xian)溫(wen)(wen)度不均勻的(de)現(xian)象(xiang)，臥式(shi)暗裝風機盤(pan)管上部溫(wen)(wen)度比較高，底(di)部現(xian)已開(kai)始(shi)凍(dong)(dong)(dong)。電(dian)(dian)加熱也(ye)不支持運用(yong)，首(shou)要電(dian)(dian)加熱簡略呈現(xian)風險，再(zai)有電(dian)(dian)加熱比較費電(dian)(dian)，不節能(neng)，在控(kong)制上也(ye)要留意不能(neng)單個臥式(shi)暗裝風機盤(pan)管開(kai)關(guan)，應當(dang)整體控(kong)制。

　　假設(she)冬季不運(yun)用(yong)臥式暗裝(zhuang)(zhuang)風機(ji)盤管(guan)(guan)，建議：將(jiang)臥式暗裝(zhuang)(zhuang)風機(ji)盤管(guan)(guan)里面的水(shui)(shui)全(quan)部(bu)放掉，b.在給(gei)水(shui)(shui)和回水(shui)(shui)上加盲板(ban)，c.運(yun)用(yong)壓縮空氣吹(chui)（依據臥式暗裝(zhuang)(zhuang)風機(ji)盤管(guan)(guan)的巨細(xi)選擇(ze)壓縮空氣吹(chui)得時間）d.給(gei)臥式暗裝(zhuang)(zhuang)風機(ji)盤管(guan)(guan)加防(fang)凍液(ye)，紛歧定要加滿，可是要保證臥式暗裝(zhuang)(zhuang)風機(ji)盤管(guan)(guan)的液(ye)體(ti)充(chong)分被防(fang)凍液(ye)稀釋。若(ruo)體(ti)系冬季停用(yong)，但有(you)熱源，可將(jiang)熱源切換至(zhi)臥式暗裝(zhuang)(zhuang)風機(ji)盤管(guan)(guan)水(shui)(shui)體(ti)系，使小循環(huan)泵工(gong)作。

　　無熱(re)源，可設一(yi)臺電加(jia)(jia)熱(re)器（殼管(guan)式的與水(shui)(shui)體(ti)系(xi)并聯）與小循環泵組合工(gong)作，使臥式暗裝風機(ji)盤(pan)管(guan)水(shui)(shui)體(ti)系(xi)管(guan)內(nei)水(shui)(shui)溫度不低于(yu)5℃，保證不凍(dong)。要將體(ti)系(xi)內(nei)的水(shui)(shui)保證5℃，電加(jia)(jia)熱(re)功率不會太大，工(gong)作費用(yong)也不高，比放水(shui)(shui)、加(jia)(jia)防凍(dong)液等辦法(fa)都可靠。
