本研究的目的是确定使用循环控制器是否会提高住宅空调或热泵的效率。循环试验是在三种配置的热泵上对毛细管进行的:制造时，通过操作液体管线中的阀门对其进行修改以模拟无排放膨胀阀装置，以及通过消除蓄能器对其进行修改以模拟空调。研究发现，液体管路阀的安装和蓄能器的拆卸这两项改进将循环性能大大提高到大致相同的水平；然而，一些周期性损失仍然存在。得出的结论是，任何导致循环运行时间缩短的控制策略都会降低所有测试设计的循环效率。部分基于其他人的工作，进一步得出结论，对于在空调空间内安装室内空气处理器和盘管的机组，风扇延迟是一种不可取的控制策略。 单位:双引文:研讨会，ASHRAE交易，1986年，第92卷，pt。1B，旧金山

The object of this study was to determine if the use of a cycling controller would improve the efficiency of a residential air conditioner or heat pump. Cyclic tests were capillary tube performed on a heat pump in three configurations: as manufactured, as modified to simulate a non-bleed expansion valve unit by operation of a valve in the liquid line, and as modified to simulate an air conditioner by elimination of the accumulator. The two modifications, the liquid line valve installation and accumulator removal, were found to greatly improve the cyclic performance to about equal levels; however, some cyclic losses remained. It was concluded that any control strategy that resulted in shortened on-cycle run times would reduce cyclic efficiency for all designs tested. It was further concluded, based in part on the work of others, that fan delay is an undesirable control strategy for units that have the indoor air handler and coil installed within the conditioned space.Units: Dual
