提出了一种适用于变速热泵和空调的最佳舒适度控制概念。控制目标是在满足舒适条件的同时，最大限度地提高系统性能（COP）。采用多维搜索技术，在给定的环境条件下，找到最佳压缩机转速、室内空气流量和蒸发器过热度。该算法的初步测试已通过模拟环境条件下住宅中变速热泵的闭环控制完成。为了说明该控制概念的性能和操作，给出了选定环境条件下的结果。 结果表明，满足舒适条件的压缩机转速和室内空气流量的组合是无限的，但只有一个组合会产生最大COP。最佳舒适性控制策略能够在控制参数的六次更新内找到所需的工作点。由此产生的COP比室内空气流量与压缩机转速成比例的传统控制策略的COP高7%。相应的输入节能为15%。最佳舒适性控制策略已经在一系列潜在和敏感的负载条件下进行了测试。每种情况下的COP改善与本文给出的结果相当。 最后，对实施问题进行了讨论。单位:双引文:研讨会，ASHRAE交易，1988年，第94卷，pt。2、渥太华

An optimal comfort control concept for variable-speed heat pumps and air conditioners is presented. The control objective is to maximize system performance (COP) while simultaneously satisfying comfort conditions. A multi-dimensional search technique is used to find the optimum compressor speed, indoor airflow rate, and evaporator superheat for given ambient conditions. Preliminary testing of the algorithm has been accomplished by simulating the closed-loop control of a variable-speed heat pump in a house subject to ambient conditions. To illustrate the performance and operation of this control concept, results are presented for a selected ambient condition. The results show that there are an infinite combination of compressor speeds and indoor airflow rates that satisfy the comfort condition, but only one results in the maximum COP. The optimal comfort control strategy is able to locate the desired operating point within six updates of the control parameters. The resulting COP is 7% higher than the COP for a conventional control strategy in which the indoor airflow rate is proportional to the compressor speed. The corresponding input energy savings is 15%. The optimal comfort control strategy has been tested over a range of latent and sensible load conditions. The COP improvement in each case is comparable to the results presented here. Finally, a discussion of implementation issues is given.Units: Dual
