本文基于1985年在阿拉巴马州开始的热泵压缩机寿命研究。热泵维护合同项目的数据已经存在了近20年，提供了七家主要制造商近18000台热泵在前10年运行的信息。主要研究结果如下:1。总的来说，数据库中59%的热泵在10年后仍在使用其原厂安装的压缩机。 2.原厂安装的压缩机的使用寿命超过10年，但无法准确确定，因为无法获得超过使用年限的维护信息。数据外推表明，所有原装压缩机的平均寿命约为13.5年。3.第一台更换压缩机（第二台压缩机）的使用寿命至少为8.9年，可能更长。4.在根据早期研究确定的整个热泵系统的20年中位使用寿命期间，热泵的平均所有者最多只能更换一次压缩机。 5.最近安装的热泵显示，压缩机故障率明显低于此处给出的平均值。引文:研讨会，ASHRAE交易，1987年，第93卷，pt。1，纽约州纽约市

This paper is based on a study of heat pump compressor life initiated in 1985 in Alabama. Data from a heat pump maintenance contract program that has been in existence for nearly two decades provided information on up to the first 10 years of operation of nearly 18,000 heat pumps from seven major manufacturers. Major findings include the following:1. Overall, 59% of all heat pumps in the data base were still operating on their original factory-installed compressors after 10 years.2. Service life of original factory-installed compressors was beyond 10 years but could not be determined precisely because maintenance information was not available beyond age. Extrapolation of the data indicates a median life of approximately 13.5 years for all original compressors as a group.3. Service life of first replacement compressors (second compressors) was at least 8.9 years, and probably longer.4. Over the 20-year median service life of total heat pump systems determined from an earlier study, the average heat pump owner can expect to replace the compressor no more than once.5. Recently installed heat pumps demonstrate markedly lower compressor failure rates than the averages presented here.
