楼宇型冷热电联产系统问题探讨
Problems in building type CCHP system
摘要：
简要论述了在我国推广天然气冷热电联产（CCHP）的意义，指出了CCHP在我国发展存在的一些问题。在不同气价、电价条件下，对楼宇型CCHP系统经济性进行了简要测算，深入探讨了楼宇CCHP系统普遍存在的系统匹配不合理、造价高、系统效率达不到预期、无法正常运行等问题，提出了改进建议。

Abstract：
Briefly discusses the importance of promoting natural gas CCHP in our country, and points out some problems existing in developing the natural gas CCHP system in China. Under the condition of different gas and electricity prices, estimates the economic efficiency of building type CCHP system, and discusses in detail the problems that exist widely in building type CCHP system such as system mismatching, high cost, system inefficiency which fails to reach the expectation, system malfunction. Puts forward some improvement suggestions.
