This research program builds upon prior experimental and numerical work funded by NSERC to investigate the use of carbon dioxide (CO2) as a natural refrigerant in automotive air-conditioning systems in particular, with a further general application to residential and commercial systems. Ozone depletion potential and global warming potential are the two established indicators for the direct environmental impact of the release of refrigerants. The hydrofluorocarbon (HFC) refrigerants, which were once expected to be acceptable permanent replacement fluids, are now on the list of regulated substances due to their impact on climate change. The current application of high global warming potential refrigerants such as R-134a has led to the revival of CO2 as a naturally occurring refrigerant.

该研究计划建立在NSERC资助的先前实验和数值工作的基础上，以研究二氧化碳（CO2）作为天然制冷剂在汽车空调系统中的使用，特别是在住宅和商业系统中的进一步普遍应用。臭氧消耗潜能值和全球升温潜能值是衡量制冷剂排放对环境直接影响的两个既定指标。氢氟碳化合物（HFC）制冷剂，曾经被认为是可接受的永久替代流体，现在由于其对气候变化的影响而被列入受管制物质清单。目前，诸如R-134 a的高全球升温潜能值制冷剂的应用已经导致CO2作为天然存在的制冷剂的复兴。
