The consumption of conventional fossil fuels and halogen-based refrigerants in refrigeration, air conditioning and heat pump systems have initiated the research interest on developing alternative energy resources and environment friendly working fluids for refrigeration, air conditioning, heat pumps and heat pipes applications. The halogen-based refrigerants have significant global warming potential, which are restricted by Paris protocol 2016. Consequently, it is essential to identify a suitable environment friendly refrigerant for replacing the existing halogen-based refrigerants. This special issue is focusing on “Energy and Environment” in Proceedings of Mechanical Engineering Part-E Journal of Processes Mechanical Engineering is dedicated to the research and developments in the field of environment friendly refrigerants for refrigeration, air conditioning, heat pump and heat pipe applications. This special issue contains the selected research papers presented in International Conference on Energy and Environment 2019 and International Conference on Environment friendly refrigerants 2020 organized by Department of Mechanical Engineering, Hindusthan College of Engineering and Technology, Coimbatore.

前言

传统化石燃料和卤素制冷剂在制冷、空调和热泵系统中的消耗引发了对开发用于制冷、空调、热泵和热管应用的替代能源和环境友好工作流体的研究兴趣。卤素基制冷剂具有显着的全球变暖潜力，这受到 2016 年巴黎议定书的限制。因此，必须确定合适的环保制冷剂来替代现有的卤素基制冷剂。本期特刊关注Proceedings of Mechanical Engineering Part-E Journal of Processes Mechanical Engineering 中的“能源与环境”致力于制冷、空调、热泵和热管应用的环保制冷剂领域的研究和开发。本期特刊包含在哥印拜陀印度斯坦工程技术学院机械工程系组织的 2019 年国际能源与环境会议和 2020 年环保制冷剂国际会议上发表的精选研究论文。
