夏热冬暖地区住宅户式中央空调的能耗比较

Comparison of Energy Consumption of Household Air Conditioning in the Regions with Warm Winter and Hot Summer

针对夏热冬暖地区住宅空调的特点,结合广东省液化天然气一体化试点项目,对比不同形式户式中央空调额定工况一次能源利用率和全年平均一次能源利用率。结果表明:天然气应用于户式中央空调中,电制冷户式中央空调的能源利用效率比较高,尤以多联空调为最高。

According to the features of household air conditioner in the regions with warm winter and hot summer and LNG project of Guandong province, primary energy ratio in standard conditions and average primary energy ratio in a year of various household air conditioner are compared. The result shows that household air conditioner powered by electricity is more efficient in natural gas utilization, in which the VRV is most efficient.
