RESEARCH ON CO_2 REFRIGERATION SYSTEM

摘要

In this paper, the main characters of CO_2 as a cooling medium and its form of refrigeration system are introduced. The technology of CO_2 refrigeration system and its experimental conclusions are then discussed. Through many data points of results and analysis, it shows that CO_2 refrigeration system has very high running efficiency and safety and environmentally friendly effect in a suitable temperature range of -55 ℃ to 5℃. CO_2 will be one of the most promising refrigerants in the near future because of its environmental protection and energy saving effect
