The table shows the median years of life expectancy of various HVACR (heating, ventilation, air conditioning, and refrigeration) equipment. The data can be used by HVAC professionals to estimate the lifespan of the equipment they are installing, repairing, or replacing.
表中提供的数据基于每种设备类型的平均预期寿命年数。这意味着该类型设备的一半预计使用寿命较长，而另一半预计使用寿命短于中值。因此，这些值应用作粗略指导，而不是作为设备使用寿命的精确估计。
还需要注意的是，HVACR 设备的使用寿命可能受到多种因素的影响，包括安装质量、维护频率和使用强度。此外，某些设备可能需要更频繁的维护，以确保最佳性能和使用寿命。
