喷气增焓空气源热泵在北方寒冷地区的应用

摘要

Based on the policies of reducing air pollution, the enhanced vapor injection (EVI) air source heat pump has been proved to be a good solution. It can be extensively applied in the northern cold area due to its high heat capacity, high heat efficiency and extensive application area. Some typical examples were analyzed to point out the application advantages of the enhanced vapor injection air source heat pump in northern China.%基于当前国内改善空气污染的政策，喷气增焓低环境温度空气源热泵是一个很好的解决方案。由于它具有高制热量、高制热能效、大应用范围的特点，适于在北方寒冷区域推广应用。通过典型应用实例，指出喷气增焓低环境温度空气源热泵在北方区域的应用优势。
