近年来,我国各地掀起了一股空调器热,其中壁挂式空调的生产和销售宣传似乎一浪高过一浪。其实,分体壁挂式空调在日本已被列入淘汰产品之列。分体壁挂式空调较之早期的窗式空调器,将压缩机移到了室外,室内噪音大为降低。但因室外压缩机与室内主机的连接管过长,加之管口的连接螺丝密封性难以保证,氟里昂慢泄漏现象时有发生,成为分体壁挂式空调的致命点。用户买此类空调若干年后,几乎每年都要加一次氟里昂,这样氟里昂不断泄漏造成周围环境污染,也增 In recent years, there has been an explosion of air conditioners throughout China, in which the production and sales promotion of wall-mounted air conditioners seems to be higher than a wave. In fact, split wall air conditioners have been included in the list of eliminated products in Japan. Split wall-mounted air conditioners have moved the compressors to the outdoors compared with earlier window-type air conditioners, and the noise in the rooms has been greatly reduced. However, due to the long connection pipe between the outdoor compressor and the indoor main unit, and the tightness of the connection screw of the nozzle, it is difficult to guarantee the slow leak phenomenon of the Freon, which becomes a fatal point of the split wall-mounted air conditioner. Some years after the user bought such air-conditioners, Freon was added almost every year, so Freon kept leaking and causing pollution to the surrounding environment.
