This research program will investigate the use of low global warming potential refrigerants in automotive as well as residential applications. Ozone depletion potential (ODP) and global warming potential (GWP) are the two well known indicators of the direct environmental impact of the release of refrigerants. Recently, the European Union has announced a directive that bans refrigerants having a GWP exceeding 150 in mobile air conditioners (MAC). The MAC directive will phase out the use of fluorinated greenhouse gases, such as R-134a (GWP=1410) in all vehicles by 2017. A preference for low GWP refrigerants has led to recent interest in such alternatives as the hydrofluoroolefin (HFO) refrigeration system. The US Environmental Protection Agency has issued final approval for the use of HFO-1234yf (GWP=4) in MAC. The key advantages of this refrigerant include zero ODP, low GWP, and low flammability with similar pressure curves to R-134a. Initial research has identified the applicability of HFOs as a potential global automotive refrigerant alternative. The main focus of this research is to develop a high performance advanced HFO refrigeration system with various cycle modifications. These modifications include using multi-fluid microchannel heat exchangers, staging compression and expansion processes, and coupling the compressor with a stand-alone vertical axis wind turbine for independent power usage. This work will be carried out in an existing versatile, state of the art refrigeration research facility at the University of Windsor. The intent of the research program is to establish design and control strategies for next-generation prototype refrigeration systems through the analysis of the experimental and numerical data obtained from this work. The technological developments proposed in this research are essential to meeting our stringent Canadian standards for environmental sustainability, enhanced vehicle performance, and customer satisfaction. Based on the recent review of literature, this research will be the first of its kind in Canada. The proposed research project offers training of highly qualified personnel, which will benefit the Canadian HVAC, environmental, energy and transportation industries greatly.

该研究计划将调查在汽车和住宅应用中使用低全球变暖潜在的制冷剂。臭氧耗竭潜力（ODP）和全球变暖势（GWP）是释放制冷剂的直接环境影响的两个众所周知的指标。最近，欧盟宣布了一项指令，该指令禁止在移动空调（MAC）中使用GWP超过150的制冷剂。 MAC指令将逐步使用氟化温室气体，例如到2017年所有车辆中的R-134A（GWP = 1410）。对低GWP制冷剂的偏爱已引起人们最近对诸如Hydrofluoroolerefin（HFO）回火系统等替代品的兴趣。美国环境保护局已发布最终批准，用于在Mac中使用HFO-1234YF（GWP = 4）。该制冷剂的关键优势包括零ODP，低GWP和低易燃性，其压力曲线与R-134A相似。最初的研究已将HFO的适用性确定为潜在的全球汽车制冷剂替代方案。 这项研究的主要重点是开发具有各种周期修改的高性能高级HFO制冷系统。这些修改包括使用多流体微通道热交换器，分期压缩和膨胀过程，以及将压缩机与独立的垂直轴风力涡轮机耦合以进行独立的功率使用。这项工作将在温莎大学现有的多才多艺制冷研究机构中进行。研究计划的目的是通过分析从这项工作中获得的实验和数值数据来建立下一代原型制冷系统的设计和控制策略。这项研究提出的技术发展对于达到我们严格的加拿大环境可持续性，增强车辆性能和客户满意度至关重要。根据最近对文献的评论，这项研究将是加拿大同类研究中的第一项。拟议的研究项目提供了高素质人员的培训，这将使加拿大HVAC，环境，能源和运输行业受益匪浅。
