双级耦合式热泵供暖系统在北京地区实际应用性能测试与分析

Performance test and analysis of a heating system with doublestage coupling heat pumps in Beijing

基于双级耦合式热泵供暖系统在我国实际工程首次应用的测试结果 ,通过对机组性能、供暖总体效果、供暖可靠性等多方面的分析 ,验证了该系统在北方寒冷地区应用的可行性 ,同时指出中间环路蓄热措施和系统调节过程将成为今后研究的重点。

Based on the test results of a project first adopting this system in China, analyses the heating performance, general heating effect, heating reliability, etc., and verifies the feasibility of applying this system in northern cold areas. Points out that the research emphases should be put on the heat storage measures in mid loops and the process of system adjustment in the future.
