空調(diào)系統(tǒng)的控制主要分為繼電器控制系統(tǒng)、直接數(shù)字式控制器(DDC)系統(tǒng)和可編程序控制器(PLC)系統(tǒng)等級幾種。由于故障率高、系統(tǒng)復雜、功耗高等明顯的缺點,繼電器控制系統(tǒng)已逐漸被淘汰。DDC控制系統(tǒng)雖然在智能化方面有了很大的發(fā)展,但由于其本身抗*力差、不易聯(lián)網(wǎng)、信息集成度不高和分級分步式結(jié)構(gòu)的局限性,從而限制了其應用。相反,PLC控制系統(tǒng)以其運行可靠、使用維護方便、抗*力強、適合新型高速網(wǎng)絡結(jié)構(gòu)等顯著的優(yōu)點,在智能建筑中得到了廣泛的應用。為了提高空調(diào)系統(tǒng)的經(jīng)濟性、可靠性和可維護性,目前空調(diào)系統(tǒng)都傾向于采用*、實用、可靠的PLC來進行控制。

采用傳統(tǒng)的繼電器控制系統(tǒng)來實現(xiàn)熱泵的控制,由于機械接觸點很多,接線復雜,參數(shù)調(diào)整不方便,而且機械接觸點的工作頻率低,容易損壞,可靠性差。采用直接數(shù)字式控制器(DDC)雖然可以減少接線,可靠性有所提高,但由于DDC其本身的抗*力差、不易聯(lián)網(wǎng)、信息集成度不高和分級分步式結(jié)構(gòu)的局限性,因此,越來越不能滿足復雜多變的智能控制要求。
