随着人们环保意识的增强,通过减少有害物排放来进行环境保护已经不足为奇,虽然这种方式是一个缓慢又长期的过程,但它在暖通空调行业的施行,已经产生了深远影响。制冷剂是空调和制冷系统的基本组成部分,但由于制冷剂可能会对臭氧层产生破坏作用或导致温室效应,因此有些制冷剂已经被减少使用甚至被完全禁止。 With the enhancement of people’s environmental awareness, it is not surprising that environmental protection through the reduction of harmful emissions is not uncommon. Although this approach is a slow and long-term process, it has had a profound impact on the HVAC industry. Refrigerants are an essential part of air conditioning and refrigeration systems, but some refrigerants have been reduced or even completely banned because they can have a damaging effect on the ozone layer or cause a greenhouse effect.
