A nationwide survey to realize China's residential air-conditions usage behaviors. Air-conditioner running time-environment temperature curves are obtained. The peak heating demand and peak cooling demand happen at 28 °C and 4 °C, respectively. The temperature of 27 °C–30 °C accounts for over 52% refrigeration time. The temperature of 0 °C–8 °C occupies more than 75% heating time.
