2014年10月,我从弗吉尼亚州北部的一家流行的安装人员买了一款Triane XV18户外单位模型#4TWV8036。该单位是取代位于我的主卧室墙壁之外的Ruud单级11 Seer单元。安装程序让我相信这个新的变速单元输出的分贝水平将远低于我们习惯的。TRANE广告本机以72分贝(47度环境温度)运行。一旦冬天击中,我们在热火上摇晃着,我就知道了一个错误,我正在乘车。长话短说,该装置在90岁的分级下运行,变速压缩机呈现出灼热的噪音,不会让我在晚上睡觉。安装人员同意分贝测试该装置并找到了相同的结果。将绝缘毯放置在压缩机上以使噪声减5分贝。安装者和特拉内的代表来到我家告诉我我的设备根据规格运行。我被告知,其他客户在XV18噪声输出中具有类似的问题,并且特拉内正在推出可能有所帮助的软件“补丁”。 It did not. The installer also offered to change my unit's compressor settings to decrease noise output, but I told the installer that I paid to have the unit run at maximum efficiency. At this point, many emails had gone back and forth between me, the installer, and the Trane rep over the course of 5 months. Since the high speed compressor was the real issue, I even asked to have my XV traded out for a two stage XL. However, Trane would refuse to reimburse me the difference between the two units. So, I was stuck with a noisy, variable speed unit. Finally, the installer agreed to move the unit to a farther point away from our bedroom at no additional cost. We are now in the AC season, and I must say that the unit is true to form during the summer months. Noise levels are as advertised when the unit is in AC mode. In conclusion, my advice to-date is to avoid placing the XV18 anywhere close to living space that requires low levels of noise. This unit offers high levels of noise output at high pitch when in heat mode at 50% or more compressor speed.
