之前对收集的灰尘、烟草烟雾/焦油和厨房活动中产生的颗粒物对热泵性能系数（COP）的累积影响进行的分析表明，翅片管盘管的颗粒物保留效率在40%到78%之间。这种保留已通过实验验证，并可在热泵或空调的使用寿命内导致显著的热交换劣化。这意味着通过使用高效空气净化器（HEAC）可以显著节约运营成本，高效空气净化器可以保留90±5%的住宅颗粒物，以防止此类劣化。我们扩大了分析和补充实验工作，以量化由于避免清洁成本和维持高运行COP而节省的运行成本。 现场调查表明，用户很少清洁盘管，因此，通过使用高效空气滤清器，可以从保持盘管清洁的计划中受益。我们的结果表明，在考虑的气候arld粉尘负荷条件范围内，这将节省平均运营成本的10%至25%（假设使用寿命为15年），或在运营第15年期间节省25%至55%。效率较低的空气滤清器或过滤器，例如仅保留20%的微粒，在其他条件相同的情况下，只能实现上述节省量的1/8左右。这些好处的巨大程度表明，当空调和热泵配备适当的空气净化器时，应制定方法，将其季节性能源性能的优点归功于它们。 包括2004年增加的附录。单位:双引文:研讨会，ASHRAE交易，1987年，第93卷，第。1，纽约州纽约市

Previous analyses of the cumulative influence of collected dust, tobacco smoke/tars and particulates generated in kitchen activities on the coefficient of performance (COP) of heat pumps indicated that the particulate-retention efficiency of finned tube coils ranges from 40 to 78%. This retention was experimentally verified, and can lead to significant heat exchange deterioration over the useful service life of a heat pump or air conditioner. This means that significant operating cost savings can be achieved by the use  of high efficiency air cleaners (HEAC) which retain 90 ± 5% of residential particulates to prevent such deterioration.We expanded the analyses and complementary experimental work to quantify the operating cost savings due to avoidance of cleaning costs and maintenance of high operating COP. Field surveys show that users seldom have their coils cleaned and, therefore, could benefit from a program to maintain coil cleanliness via application of efficient air cleaners. Our results show that this would save from 10 to 25% of averaged operating costs (for each of the assumed 15 years of service life), or from 25 to 55% during the 15th year of operation, for the range of considered climatic arld dust-loading conditions. Lower efficiency air cleaners or filters, retaining e.g. only 20% of the particulates, would only realize about 1/8 of the above savings under otherwise equal conditions. The magnitude of these benefits suggests that means should be developed to credit the seasonal energy performance figures of merit of air conditioners and heat pumps when they are equipped with appropriate air cleaners.Includes appendix added in 2004.Units: Dual
