Number: pap. n. E207

Author(s) : ZGLICZYNSKI M., SEDLIAK J.

Summary

Embraco for many years is present as a one of the more active companies in promoting hermetic compressors for use with alternative refrigerants worldwide. Apart of isobutane in household type of appliances, significant progress was done in propane implementation into light commercial plug-in systems as R404A natural alternative. Recent F-Gas EU regulation is considering ban of high GWP refrigerants in next few years in many types of commercial applications and will considerably limit the available quantities on the market. Apart of hydrocarbons many alternative refrigerants were offered by chemical industry. Embraco performed a number of activities to assess their capacity to replace high GWP refrigerants presently in use. Main difficulty was found when trying to replace R404A. This paper will summarize present state of art in alternatives testing like R407A, R407F, R448A, R449A and others. Focus will be given to reliability aspects rather than to cooling capacity and efficiency.
