发展中国家,如印度和中国应该最先接受对臭氧层没有危害的制冷剂 HFC134a 的大量供给。如果发展中国家不能优先得到供给,那么他们就有被迫依赖 CFCs 的危险性,这样,就会对臭氧层造成进一步的危害。这个建议由供暖、通风、承包商协会(HVCA)提出,该协会代表了那些对超级市场、冷藏库、及四库所使用的制冷系统进行设计、安装、维修的公 Developing countries such as India and China should be the first to accept a large supply of refrigerant HFC134a, which is not harmful to the ozone layer. If developing countries are not given priority in providing supplies, they are at risk of being forced to rely on CFCs, thus further damaging the ozone layer.
