LOW-CHARGE AMMONIA TECHNOLOGY IN NORTH AMERICA,CHINA, JAPAN AND EUROPE

摘要

Ammonia has been widely used as the refrigerant of choice in industrial refrigeration for more than a century;rnhowever, the technology used has not undergone any major changes during that time. With growing pressurernto improve safety and increase energy efficiency, low charge ammonia systems in particular have beenrngaining popularity. While the concept of low charge is not new, it represents the leading disruptor in therntraditional industrial refrigeration market. This new technology is also leading to ammonia being consideredrnfor applications where it has traditionally not been used, such as HVAC and food retail.rnThis paper outlines the market, technology and policy trends for the low charge ammonia technology inrnEurope, North America, Japan and China, drawing conclusions from a global study on low charge ammonia.rnIt will also propose a definition for what constitutes a “low charge” system, and an overview of case studies,rnindicating potential new markets for ammonia.
