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

采用傳統的繼電器控制系統來實現熱泵的控制，由于機械接觸點很多，接線復雜，參數調整不方便，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、不易聯網、信息集成度不高和分級分步式結構的局限性，因此，越來越不能滿足復雜多變的智能控制要求。
