The EU Regulation No 517/2014 is going to phase-out most of the refrigerants commonly used in refrigeration and air conditioning systems (R134a, R404A and R410A) because of their extended use and their high GWP values. There are very different options to replace them; however, no refrigerant has yet imposed. In this paper we review and analyze the different mixtures proposed by the AHRI as alternative refrigerants to those employed currently. These mixtures are composed by HFC refrigerants: R32, R125, R152a and R134a; and HFO refrigerants: R1234yf and R1234ze(E). It is concluded, from the theoretical analysis, that most of the new HFO/HFC mixtures perform under the HFC analyzed (although some experimental studies show the contrary) and, in most cases, do not meet the GWP restrictions approved by the European normative. Furthermore, some of the mixtures proposed would have problems due to their flammability. 相似文献

The structure of Swedish research finance was radically changed in 2001, and the present goals of research policy are that Sweden is to be a leading research nation, where research with a high scientific quality is conducted. However, the process of internationalizing Swedish building research leads to an issue of how international standards for scientific quality are applied and how Swedish researcher participation in industry initiatives and European framework programmes is supported. This issue is discussed against a background of a national system where research funding is indirectly and strongly linked to university teaching, which also means that research institutes are comparatively unimportant. International expansion of large firms in the construction industry has led to an increasing engagement with university research. However, the current process intended to guarantee high scientific quality in projects with national funding is inflexible and not fully compatible with what is required for industry and European research cooperation. 相似文献
