商用中央空调未经处理的循环水不能直接向外排放，必须另行安置水处理设备经处理后方可排放。而经过最新开发的技术处理后的循环水其水质达到国家环保要求的排放标准，可直接向外排放，这样既可为业主节约费用，又保护生态环境。
The untreated circulating water of the commercial central air conditioner cannot be discharged directly. The water treatment equipment must be installed separately for treatment before discharging. The water quality of the newly developed circulating water can meet the discharge standard of national environmental protection requirements and can be discharged directly to the outside, which can not only save the cost for the owner, but also protect the ecological environment.
