给出了一种新型结构的多功能家用中央空调,其一套装置可同时兼有供冷、供暖及供热水功能,且制冷剂管道分布简单,控制方便.对其结构和工作原理进行了介绍,分析了其能耗、经济和环境指标,并对其运行特性进行了实验研究.研究表明,与传统系统相比,多功能家用中央空调的初投资可降低30%以上,全年能耗费用可减少25%以上,环境负荷可减少44%以上. A new structure of multi-function household central air conditioner is presented, which has the functions of cooling, heating and hot water supplying, and has the advantages of simple distribution of refrigerant pipes and convenient control. The structure and working principle of the utility model are described The energy consumption, economic and environmental indexes are introduced, and the operating characteristics are also studied experimentally.The research shows that compared with the traditional system, the initial investment of the multifunctional home central air conditioner can be reduced by more than 30%, and the annual energy consumption The cost can be reduced by more than 25% and the environmental load can be reduced by 44% or more.
