 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(jí)幾種。由于故障率高、系統(tǒng)復(fù)雜、功耗高等明顯的缺點(diǎn)，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(jí)分步式結(jié)構(gòu)的局限性，從而限制了其應(yīng)用。相反，PLC控制系統(tǒng)以其運(yùn)行可靠、使用維護(hù)方便、抗*力強(qiáng)、適合新型高速網(wǎng)絡(luò)結(jié)構(gòu)等顯著的優(yōu)點(diǎn)，在智能建筑中得到了廣泛的應(yīng)用。為了提高空調(diào)系統(tǒng)的經(jīng)濟(jì)性、可靠性和可維護(hù)性，目前空調(diào)系統(tǒng)都傾向于采用*、實(shí)用、可靠的PLC來(lái)進(jìn)行控制。

采用傳統(tǒng)的繼電器控制系統(tǒng)來(lái)實(shí)現(xiàn)熱泵的控制，由于機(jī)械接觸點(diǎn)很多，接線復(fù)雜，參數(shù)調(diào)整不方便，而且機(jī)械接觸點(diǎn)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(jí)分步式結(jié)構(gòu)的局限性，因此，越來(lái)越不能滿足復(fù)雜多變的智能控制要求。
