将用于全年住宅空间供暖和供冷的专用机械过冷（DMS）跨临界CO2系统与传统供暖/供冷解决方案进行了比较。建立了环境经济分析模型，研究了系统的可行性和性能，并选择了8个典型的中国城市作为评估方案。在CO2系统中引入DMS可显著降低年一次能源消耗（PEC），与基准CO2系统、燃煤锅炉（CFB）+传统空调（TAC）和直接电加热（DEH）+ TAC系统相比，年PEC分别降低8.65%、15.66%和55.41%。严寒地区和寒冷地区的PEC值较高，采用小温差风机盘管作为供冷/制热终端时PEC值最低。当建筑围护结构的节能潜力为65%时，PEC可降低47.90%。气体和固体颗粒物的排放也可以显着减少3.80-9.75%，与基础CO2系统相比。在广州地区使用带STD-FCU的DMS CO2系统，其寿命周期成本（LCC）性能得到改善，最低水平化年总收益需求（TRRL）为7924.93 CNY，比BASE系统低4.51-14.04%。CO2压缩机和电价对LCC和投资回收期有显著影响。DMS CO2系统是一个有前途的解决方案，每年的空间加热和冷却的帮助下，上网电价和CO2压缩机的价格下降。
Dedicated mechanical subcooling (DMS) transcritical CO2system for annual residential space heating and cooling is compared with traditional heating/cooling solutions. Environmental and economic analysis model is established to study the system feasibility and performance, and eight typical Chinese cities are selected as the evaluated scenarios. The annual primary energy consumption (PEC) can be considerably reduced by introducing DMS to CO2system, which is up to 8.65, 15.66, and 55.41% in comparison with baseline (BASE) CO2system, coal-fired boiler (CFB) + traditional air conditioner (TAC), and direct electric heating (DEH) + TAC system, respectively. The PEC is higher for the severe cold and the cold region, and it is the lowest when small temperature difference fan-coil unit (STD-FCU) is utilized as heating/cooling terminal. The PEC can be reduced by 47.90% when the energy-saving potential for the building envelope is 65%. The gaseous and solid particulate matter emissions can also be significantly decreased by 3.80–9.75% in comparison with BASE CO2system. The life cycle cost (LCC) performance is improved, and a lowest levelized annual total revenue requirement (TRRL) of 7924.93 CNY is obtained when DMS CO2system with STD-FCU is used in Guangzhou, which is 4.51–14.04% lower compared with BASE system. CO2compressor and electricity price have significant impact on the LCC and payback period. DMS CO2system is a promising solution for annual space heating and cooling with the help of feed-in tariff and CO2compressor price reduction.
