Yaroslavl AO Kholodmash: Refrigeration hermetic compressors on R600a

Development of refrigeration equipment is now under the influence of three interrelated factors defined by ecological problems: requirements of Montreal Protocol about cessation of consumption of substances destroying ozone layer, requirements of Kyoto Protocol to the "UN Framework Convention on Climate Change" about regulation of greenhouse gas emission, traditional requirement to increase energy efficiency of all kinds of refrigeration equipment. Use of isobutane (R600a) seems to be a perspective direction for ensuring full ecological safety of refrigeration equipment, first of all, domestic and commercial equipment with small refrigerant charges.
