Background: Meng Li Trier each year because it 4-5 on the famous winter.

背景：蒙利特利尔因为它每年4到5个月的冬季而闻名。

In the winter solstice this day, regarding was located Northern Hemisphere's Taiwan, by now the solar just perpendicular incidence (was called the winter solstice line) in the the tropic of capricorn on, caused Taiwan to be in the winter the season, therefore caused Northern Hemisphere's daytime to be shortest, the dark night was longest.

在冬至这一天，对于位于北半球的台湾，这时太阳刚好直射在南回归线上，使得台湾处于冬季的季节，因此使得北半球的白天最短，黑夜最长。

In the northern high latitudes the tropopause height is maximum during summer and winter.

在南半球的高纬地区和北半球的热带地区是冬高夏低；而在北半球的高纬地区在冬季和夏季有两个锋值存在。

This thesis analyzes the types and art trait of solar-assisted heat pump water heater, the development trend of direct expansion solar-assisted heat pump water heater, makes a summary of these research results from six aspects. On the basis of these works and from the point of view of receiving optimum solar radiation , the thesis develops a novel design model of direct expansion solar-assisted heat pump water heater with a truncated cone collector/evaporator, theoretically analyzes the heat that the system can absorb, compares its ability with other two types of cylinder and flat plate ones, and calculates COP and EER with computer aids. The results show that a truncated cone direct expansion solar-assisted heat pump water heater can absorb not only more solar energy but heat energy in air. It takes on favorable thermal performance. Under the average day in February which is of the worst weather throughout the year in Kunming, the COP is about 4. 2, EER is about 2.9 . The heat absorbed by the system are more than those of the other systems. The system is very great in terms of saving

本文分析研究了太阳能热泵热水系统的分类及技术特点，直膨式太阳能热泵技术国内外发展趋势，从六个方面对直膨式太阳能热泵热水系统的研究进行了归纳总结；在此基础之上，从太阳辐射的最佳接收考虑，提出了集热器／蒸发器为圆台侧面的圆台型直膨式太阳能热泵热水器的设计模型，理论上分析了这种热水系统所接收的太阳辐射和得热量，并与圆柱型、平板型的直膨式太阳能热泵热水系统进行对比分析，通过计算机辅助模拟计算出：系统不但可以有效地吸收太阳能，还能有效地吸收空气中的热量，具有良好的热性能；在昆明，以2月为代表的冬季，其太阳辐照较低，系统的制热系数COP值也能达到4.2，效能比EER值为2.9；系统的得热量高出圆柱型、平板型的直膨式太阳能热泵热水系统，节能效果明显。

This served in lieu of a watch or clock to the poor women of the quarter who said,"It is two o'clock; there he is returning to the Tuileries."
