制冷、制热管路的安装注意以下几个方面：
Pay attention to the following aspects for the installation of refrigeration and heating pipelines:
①室外机要先固定好之后，才能连接制冷、制热管路。
① The outdoor unit shall be fixed before connecting the refrigeration and heating pipelines.
②安装制冷剂连接管前必须先确认室外机高低压阀完全关闭到位。
② Before installing the refrigerant connecting pipe, it must be confirmed that the high and low pressure valves of the outdoor unit are fully closed in place.
③安装制冷剂连接管时要避免使水分或其他杂物等进入连接管。
③ When installing the refrigerant connecting pipe, avoid moisture or other sundries entering the connecting pipe.
④制冷、制热管路的连接要严密，检査时除了用肥皂水检漏外，还要仔细观察连接处是否有油渍。如果有则说明该处有渗漏，应重新给予坚固处理。假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵分体空调器的管路宜短不宜过长，过长的管路影响制冷制热效果。铜管的弯处不可有弯瘪，以保证制冷制热畅通无阻。
④ The connection of refrigeration and heating pipelines shall be tight. During inspection, in addition to detecting leakage with soapy water, carefully observe whether there are oil stains at the connection. If yes, it indicates that there is leakage at this place, and it shall be hardened again. The pipeline of split air conditioner should be short rather than too long, which will affect the refrigeration and heating effect. The bend of the copper pipe shall not be bent to ensure smooth refrigeration and heating.
