Global Climate Change In December, international negotia- tions in Kyoto, Japan will address the climate change issue. In 1992 the devel- oped nations pledged to return their emission levels of greenhouse gases t

46、o 1990 values by the Year 2000. This goal will only be achieved by two or three nations. The US. will be about 12% above its targeted value. According to Wolf, an agreement in the form of a pro- tocol or other legal instrument can be expected in Kyoto later this year. Among other comments, Wolf said

47、 that when HCFC-22 is phased out in the next century, substitute refrigerants will be ready. Equipment for two alternatives is now being developed. In other comments, he said part of the solution to the climate change issue 20 ASHRAE Journal hinges on reducing energy consumption through improved ene

Although flammable refrig- erants are used in refrigerators in some parts of Europe, the typical refrigerator in the U.S. is significantly different from those in other parts of the world.
