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.

该研究项目建立在 NSERC 资助的先前实验和数值工作的基础上，旨在研究二氧化碳 (CO2) 作为天然制冷剂在汽车空调系统中的使用，并进一步普遍应用于住宅和商业系统。臭氧消耗潜势和全球变暖潜势是衡量制冷剂释放对环境直接影响的两个既定指标。氢氟碳化物 (HFC) 制冷剂曾经被认为是可接受的永久性替代液体，但由于其对气候变化的影响，现在已被列入受管制物质清单。目前 R-134a 等高全球变暖潜势制冷剂的应用使得二氧化碳作为一种自然产生的制冷剂得以复兴。
