高效换热器不但可以减少空调器的重量,缩小其尺寸,而且可使空调器的噪声得到明显下降。空调器的噪声来自制冷压缩机和风机,随着压缩机制造水平的不断提高,其发出的噪声越来越低。国外七十年代中期的一些低噪声房间空调器,经我们测试,其高冷挡噪声与高风挡噪声相等,这说明压缩机工作时发出的噪声并不影响空调器整机的噪声。七十年代后期,分体式空调器的出现,使房间空调器的噪声得到更进一步的下降。压缩机放在室内的落地式空调器噪声只有45分贝左右,如日本松下电气公司的1、1.5、2马力落地式室内机组至于挂墙式、吊顶式室内机组出于安装方便及超薄型造
The efficient heat exchanger not only reduces the weight of the air conditioner, reduces its size, but also allows the air conditioner noise to be significantly reduced. The noise of the air conditioner comes from the refrigeration compressor and the fan. With the continuous improvement of the compressor manufacturing level, the noise emitted by the compressor is getting lower and lower. Some of the low-noise room air conditioners in the mid-1970s abroad were tested by us. Their high cold-blocking noise and high wind-block noise are equal, which means that the noise emitted by the compressor during operation does not affect the noise of the whole air conditioner. In the late 1970s, the emergence of split-type air conditioners further reduced the noise of the room air conditioners. The noise of the floor-standing air conditioner with the compressor placed in the room is only about 45 decibels. For example, the 1, 1.5, and 2 horsepower floor-standing indoor units of Panasonic Electric Co., Ltd. As for the wall-mounted and ceiling-mounted indoor units, the installation is easy and ultra-thin
