摘要
由于氟利昂制冷剂已被淘汰,R32、丙烷(R290)和R600a等碳氢化合物制冷剂得到迅速发展,但也面临着安全隐患——可燃烧。这就意味着可燃制冷剂空调器性能试验室需要进行模拟泄露实验来提高安全性。根据一个可测试3HP可燃制冷剂空调器性能试验室,说明模拟泄露实验的方法,并介绍进行模拟泄露实验的基本要求;同时,根据模拟泄露实验的方法和基本要求,运用Fluent模拟来对比分析吸风罩在模拟泄露实验中的作用。该实验能够模拟可燃制冷剂泄漏的实际环境,能对泄露制冷剂在性能试验室的浓度进行测量,最终,确定了吸风罩对减少局部浓度过高现象有明显的作用,也为可燃制冷剂空调器性能试验室提供了新的安全措施。
Due to the elimination o f Freon, the Hydrocarbons refrigerants, such as R32, R290 and R600 a , get a rapid development, but has the flammable nature. So, the flammable refrigerant a ir conditioners testing laboratory need to do leaking simulation experiment to improve its security. Based on a testing laboratory which can test 3 HP flammable refrigerant a ir conditioners, the way and the basic requirements of simulating leaking experiment was explained. A t the same time, according to them, Fluent software is applied to prove the importance o f Suction hood in simulating leaking experiment. The leaking experiment could simulate actual operation environment, it could measure concentration of leakage refrigerants in the testing laboratory. Finally , it determined that suction hood had obvious effect to reduce the high concentration on partial space. It could also provide the testing laboratory a new safety measurement.
