随着人们对大气中臭氧和地球有限资源的日益关注，制冷剂正变得越来越受管制，并被鼓励进行适当回收。回收服务公司回收制冷剂已有30多年的经验可能会增加该行业的技术知识。必须解决许多安全问题，才能正确地行使这一可行的选择。单位:I-PCITION:研讨会，ASHRAE交易，1988年，第94卷，pt。2、渥太华

With increasing concern about ozone in the atmosphere and the earth's limited resources, refrigerants are becoming more regulated and encouraged to be properly recycled. The experiences of a recovery services company that has recycled refrigerants for over 30 years may add to technical knowledge of the industry. Many safety issues must be addressed so that this viable option can be exercised properly.Units: I-P
