空气源热泵已广泛应用于华北等地区的集中供暖,但目前鲜有关于其调节方式的研究。为了提升空气源热泵的节能效果,本文建立空气源热泵集中供暖系统的数学模型,该模型考虑结除霜损失和启停损失,基于该模型提出3种适合于空气源热泵的调节方式,应用该模型对北京等7个城市的集中供暖系统进行研究。结果表明,结除霜损失修正和启停损失修正均对机组的耗电量及季节性能系数(SCOP)产生重要影响:结除霜损失修正使机组的耗电量增大3.85%~17.41%,SCOP降低3.72%~14.83%,启停损失修正的影响会随着供暖面积的增大逐渐降低;采用不同调节方式时,机组的耗电量变化不大,水泵节能80.97%~86.46%,系统节能8.47%~11.87%。

Core-mantle friction induced by the precession of the Moon's spin axis is a strong heat source in the deep lunar mantle during the early phase of a satellite's evolution, but its influence on the long-term thermal evolution still remains poorly explored. Using a one-dimensional thermal evolution model, we show that core-mantle friction can sustain global-scale partial melting in the upper lunar mantle until ～3.1 Ga, thus accounting for the intense volcanic activity on the Moon before ～3.0 Ga. Besides, core-mantle friction tends to suppress the secular cooling of the lunar core and is unlikely to be an energy source for the long-lived lunar core dynamo. Our model also favours the transition of the Cassini state before the end of the lunar magma ocean phase(～4.2 Ga), which implies a decreasing lunar obliquity over time after the solidification of the lunar magma ocean. Such a trend of lunar obliquity evolution may allow volcanically released water to be buried in the lunar regolith of the polar regions. As a consequence, local water ice could be more abundant than previously thought when considering only its accumulation caused by solar wind and comet spreading.

DURING our discussion at workshops for writing“What Does ChatGPT Say:The DAO from Algorithmic Intelligence to Linguistic Intelligence”[1],we had expected the next milestone for Artificial Intelligence(AI)would be in the direction of Imaginative Intelligence(II),i.e.,something similar to automatic wordsto-videos generation or intelligent digital movies/theater technology that could be used for conducting new“Artificiofactual Experiments”[2]to replace conventional“Counterfactual Experiments”in scientific research and technical development for both natural and social studies[2]-[6].Now we have OpenAI’s Sora,so soon,but this is not the final,actually far away,and it is just the beginning.
