本文基于对伊利诺伊州北部安装的热泵使用寿命和压缩机寿命的研究。为了收集有关热泵寿命和维修特征的信息，对热泵所有者进行了调查。调查共包括684台热泵。此处给出了系统总寿命和压缩机更换结果。本研究的主要发现包括以下几点:1。伊利诺伊州北部的热泵使用寿命中值在15到16年之间；2.经过十年的使用，调查中69%的热泵仍在使用原压缩机；3.在已安装热泵的所有受调查家庭中，96%仍在使用热泵。 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 service life and compressor longevity for installations in northern Illinois. Heat pump owners were surveyed for the purpose of collecting information on heat pump life and repair characteristics. A total of 684 heat pumps were included in the survey. Total system life and compressor replacement results are presented here. Major findings of the study include the following:1. The median heat pump service life in northern Illinois is between 15 and 16 years;2. After ten years of use, 69% of all heat pumps in the survey are still using the original compressor;3. Of all households surveyed where a heat pump had been installed, 96% were still using heat pumps.
