建筑供暖电气化是实现碳中和目标的有效途径。作为一种清洁和可持续的电气化供暖技术,空气源热泵被广泛应用于缺乏集中供暖的地区。然而,现有末端形式存在难以同时实现间歇性和舒适性,且作为主要构件尚未较好地与空气源热泵匹配等问题。因此,本研究提出了一种与空气源热泵结合的新型辐射可调节供暖末端,以实现电气化节能减碳、间歇性和更好的热舒适性。针对辐射供暖末端目前存在三个主要问题,分别是峰值供热量受限、可调节性受限以及难以与空气源热泵结合,本文通过改进末端结构设计(改进A~E)提供了有效解决方案。研究结果表明,新末端能够将峰值供热量提升23.6%,并为使用者提供从10.1%到30.9%的可调辐射比。在此基础上,巧妙地借助平板热管减少了原有直膨式辐射供暖末端的制冷剂管路长度,进而改善了供暖末端的稳定性(利于回油)、间歇性(降低热惯性)和安全性(降低制冷剂泄漏风险)。此外,本文基于新末端提出了一种新的分阶段运行策略,可进一步提升末端的可调节性。本研究可以为电气化供暖助力建筑低碳提供一定参考。

分析了变频驱动并联水泵变压变流量运行优化调度问题的常用建模方法,并比较了各种方法的优劣。 常用的方法是以水泵轴功率作为目标函数,以供水指标和高效区为约束条件。另一种方法是以满足扬程指标时 的实际流量与所需流量之差的二次方作为目标函数,以水泵的高效区作为约束条件。提出了一种新的建模方法, 模型物理意义与实际工况严格相符,具有较高的精度,满足了工程中对水泵切换频率尽量小的要求。仿真结果 表明该方法是有效的。
INTERACTIONS BETWEEN ABOVE AND BELOW GROUND PLANT STRUCTURES: MECHANISMS AND ECOSYSTEM SERVICES
《农业科学与工程前沿(英文)》 2022年 第9卷 第2期 页码 197-213 doi: 10.15302/J-FASE-2021433
Interactions between above and below ground parts of plants can be considered under the (overlapping) categories of energy, material and information. Solar energy powers photosynthesis and transpiration by above ground structures, and drives most water uptake through roots and supplies energy as organic matter to below ground parts, including diazotrophic symbionts and mycorrhizas. Material transfer occurs as water and dissolved soil-derived elements transport up the xylem, and a small fraction of water moving up the xylem with dissolved organic carbon and other solutes down the phloem. The cytosolic nature of sieve tubes accounts for at least some of the cycling of K, Mg and P down the phloem. NO3– assimilation of above ground parts requires organic N transport down phloem with, in some cases, organic anions related to shoot acid-base regulation. Long-distance information transfer is related development, biotic and abiotic damage, and above and below ground resource excess and limitation. Information transfer can involve hydraulic, electrical and chemical signaling, with their varying speeds of transmission and information content. Interaction of above and below ground plant parts is an important component of the ecosystem service of storing atmospheric CO2 as organic C in soil, a process that has decreased since the origin of agriculture.
