摘要:
为提升跨临界CO2空气源热泵系统的低温制热性能，扩宽低温工况运行范围，针对目前闪发补气型系统补气过程热力学建模过于理想化与实际工况偏差较大的问题，对闪发补气型跨临界CO2空气源热泵供暖系统（CO2 HPVI, FLA ）展开研究。通过非稳态流动能量方程，基于补气过程中压力动态调节的新热力学模型，建立了综合评价系统节能、环境和经济性能的数学模型，并选取哈尔滨（严寒区域）和北京（寒冷区域）作为工况，与燃煤锅炉（CFB）、燃气壁挂炉（WGB）和直接电采暖（DEH）三种传统型供暖方式进行了热力性、经济性和环境排放性能的分析对比。结果表明：相比于基准系统，在相同工况下闪发补气型系统的COP提升幅度可达38.5 %，㶲损失降幅超过20 %；与基准系统相比，CO2 HPVI, FLA 系统的CO2、SO2及NOx排放量均降低了19.4 7 %；同时在极寒地区，CO2 HPVI, FLA 系统在第8年的生命周期成本相较于CFB系统可降低39.7 3 %。因此，该系统在综合性能方面（能量、㶲、经济性和环境评价模型）显著优于基准系统，为清洁供热提供了一种可行的替代方案。
Abstract:
In order to enhance the low-temperature heating performance of the transcritical CO2 air-source heat pump system and broaden the operating range of the low-temperature operating conditions, the thermodynamic modeling of flash gas-supplementing is too ideal and the actual operating conditions deviate greatly. The flash gas-supplementing transcritical CO2 air source heat pump heating system ( CO2 HPVI, FLA) was studied. Through the non-steady-state flow energy equation, based on the new thermodynamic model of pressure dynamic adjustment in the process of air supply, a mathematical model for comprehensive evaluation of energy saving, environmental and economic performance of the system was established. Harbin ( severe cold area) and Beijing ( cold area) were selected as working conditions, and coal fired boiler, gas fired wall mounted boiler and direct electric heating are selected. The three traditional heating methods were analyzed and compared in terms of thermal performance, economy and environmental emission performance. The results indicated that compared with the reference system, the COP of the flash gas supplementing system can be increased by 38. 5% and the exergy loss can be reduced by more than 20% under the same working conditions. Compared with the baseline system, the CO2 , SO2 and NOx emissions of the CO2 HPVI, FLA system are reduced by 19. 47%. At the same time, in the extremely cold region, the life cycle cost of the CO2 HPVI, FLA system in the eighth year can be reduced by 39. 73% compared with the CFB system. Therefore, the system is significantly superior to the benchmark system in terms of comprehensive performance ( energy, exergy, economic and environmental evaluation models) , providing a feasible alternative to clean heating.
