Abstract：

The decentralized and independent characteristics of split air conditioners make it difficult to be effectively monitored and managed, which can easily cause energy waste. Based on the Internet of Things, the split air conditioner of a hotel has been energy saving control transformation. By controlling the operation of the compressor, reduces the energy waste caused by the user’s low temperature setting in summer. The comparative analysis of the macro and micro aspects shows that turning on the energy saving control can effectively reduce the energy consumption of the air conditioner, but the energy saving rates produced by different split air conditioners are quite different.
