空调系统的控制主要分为继电器控制系统、直接数字式控制器（DDC）系统和可编程序控制器（PLC）系统等级几种。由于故障率高、系统复杂、功耗高等明显的缺点，继电器控制系统已逐渐被淘汰。DDC控制系统虽然在智能化方面有了很大的发展，但由于其本身抗*力差、不易联网、信息集成度不高和分级分步式结构的局限性，从而限制了其应用。相反，PLC控制系统以其运行可靠、使用维护方便、抗*力强、适合新型高速网络结构等显著的优点，在智能建筑中得到了广泛的应用。为了提高空调系统的经济性、可靠性和可维护性，目前空调系统都倾向于采用*、实用、可靠的PLC来进行控制。

采用传统的继电器控制系统来实现热泵的控制，由于机械接触点很多，接线复杂，参数调整不方便，而且机械接触点的工作频率低，容易损坏，可靠性差。采用直接数字式控制器（DDC）虽然可以减少接线，可靠性有所提高，但由于DDC其本身的抗*力差、不易联网、信息集成度不高和分级分步式结构的局限性，因此，越来越不能满足复杂多变的智能控制要求。
