3.3除霜控制
冬季機(jī)組做熱泵運(yùn)行時(shí)，特別是當(dāng)環(huán)境溫度接近0℃或低于0℃時(shí)，機(jī)組將出現(xiàn)結(jié)霜狀況。除霜時(shí)采用互鎖控制，避免溫度波動(dòng)過(guò)大，即系統(tǒng)1進(jìn)入除霜時(shí)，系統(tǒng)2不能同時(shí)進(jìn)入除霜，系統(tǒng)3進(jìn)入除霜時(shí)，系統(tǒng)4不能同時(shí)進(jìn)入除霜；除霜時(shí)投必要的電加熱。當(dāng)機(jī)組進(jìn)入制熱工況后，低溫低壓的制冷劑進(jìn)入翅片換熱器，盤(pán)管溫度不斷下降，吸氣溫度也隨著下降，當(dāng)盤(pán)管溫度下降到設(shè)定值時(shí)，并且除霜周期已到，plc控制四通換向閥換向進(jìn)入除霜模式，同時(shí)停止冷凝風(fēng)機(jī)，啟動(dòng)電加熱器；當(dāng)蒸發(fā)器盤(pán)管溫度上升到設(shè)定值，或除霜執(zhí)行時(shí)間到達(dá)設(shè)置的zui長(zhǎng)除霜時(shí)間，四通閥換向，除霜結(jié)束，電加熱停止運(yùn)行，機(jī)組又進(jìn)入制熱工況，如此循環(huán)下去。

3.4加濕器控制
送風(fēng)機(jī)啟動(dòng)后，當(dāng)室內(nèi)相對(duì)濕度低于設(shè)定值時(shí)，加濕器按比例投入。若選用電極加濕器，則在加濕器上配有加濕控制板，能自動(dòng)進(jìn)行進(jìn)、排水控制，為方便用戶使用，在plc還加上加濕器手動(dòng)排水和定時(shí)排水控制。
