4、stility varies with the season of the year and with the geographical locality. This suggests that the arguments for air conditioning might be based solely on climatic considerations, but although these may be valid in tropical and subtropical areas, they are not for temperate climates with industria

5、lized social structures and rising standards of living. 人类生活在一个并不舒适的环境，但是这种不舒适的程度因季节的变化和地理位置的不同而不同。 空调设计似乎仅仅考虑气候因素就够了，虽然这在热带和亚热带区域是可行的，但它们并不适合生活标准不断提高和工业化社会结构下的温带气候。 1-6制冷空调专业英语Unit One Briefly，air conditioning is necessary for the following reasons. Heat gains from sunlight and electric lighting, i

6、n particular, may cause unpleasantly high temperatures in rooms, unless windows are opened .If windows are opened, then even moderate wind speeds cause excessive draughts, becoming worse on the upper floors of tall buildings. 简而言之，空调为下列情况所必需。太阳光，尤其是电灯照明的热量，会使房间内的气温很高，令人不舒服，这时就需要打开窗户；而如果窗户被打开，那么即使是中等

7、程度的风速也能导致通风过度，较高楼层上的房间情况会更糟。 Lesson 2Text:1-7制冷空调专业英语Unit One Further, if windows are opened, noise and dirt enter and are objectionable，becoming worse on the lower floors of buildings, particularly in urban districts and industrial areas .In any case, the relief provided by natural airflow through

8、open windows is only effective for a depth of about 6 meters inward from the glazing. 进一步说，如果窗户打开，噪声和灰尘就会进入，令人讨厌，尤其是市区和工业区建筑物的最低层情况会变得更糟糕。通过开窗获得自然气流去缓和这种情况，仅限于从玻璃窗向内6米的范围之内。 Lesson 2Text:1-8制冷空调专业英语Unit One It follows that the inner areas of deep buildings will not really benefit at all from opened

9、windows. Coupled with the need for high intensity continuous electric lighting in these core areas, the lack of adequate ventilation means a good deal of discomfort for the occupants. 1 Mechanical ventilation without refrigeration is only a partial solution. 由此得出，事实上开窗对纵深的建筑物内部的区域根本无效。加上这些中心区域要有高强度长

10、时间的照明，缺少足够的通风会使居住者感到非常不适。不带制冷的机械通风仅仅只能解决一部分问题。 Lesson 2Text:1-9制冷空调专业英语Unit One It is true that it provides a controlled and uniform means of air distribution, in place of the unsatisfactory results obtained with opened windows (the vagaries of wind, again particularly with tall buildings, produce d

12、o augment the mechanical ventilation.2 机械的通风确实能提供一个可控制、均匀的空气分配，弥补了开窗通风的缺点（自然风难以预测，通风断断续续，尤其是高层建筑），而只有在冬季这样的室内温度才是适宜的。因为大部分春季和秋季，还有夏季，室内温度比室外温度高出好几摄氏度，为了弥补机械通风的不足，就需要打开窗户。Lesson 2Text:1-10制冷空调专业英语Unit One The design specification for a comfort conditioning system is intended to be the framework for p

13、roviding a comfortable environment for human beings throughout the year, in the presence of sensible heat gains in summer and sensible heat losses in winter. Dehumidification would be achieved in summer but the relative humidity in the conditioned space would be allowed to diminish as winter approac

14、hed. 舒适的调节系统的设计规范是为居住者提供全年的舒适环境，这就要面临夏季人们明显的热量获得和在冬季明显的热量损失的问题。在夏季应实现除湿，而当冬季接近时应允许减少在空调环境中相对的湿度。 Lesson 2Text:1-11制冷空调专业英语Unit One There are two reasons why this is acceptable first, 3 human beings are comfortable within a fairly large range of humidity, from about 60 per cent to about 20 percent an

15、d, secondly the use of single glazing will cause the inner surfaces of windows to stream with condensed moisture if it is attempted to maintain too high a humidity in winter. 理由有两个，第一，人类能在一个湿度相当大的范围内感到舒适，大约从60%到20%；第二，如果想在冬天保持一个较高的室内温度，蒸汽就会在单层的玻璃内表面上冷凝成水。Lesson 2Text:1-12制冷空调专业英语Unit One The essenti

16、al feature of comfort conditioning is that it aims to produce an environment which is comfortable to the majority of the occupants .The ultimate in comfort can never be achieved, but the use of individual automatic control for individual rooms. 舒适条件的基本特征是有目的地产生一个大多数人会感到舒适的环境。绝对的舒适是永远达不到的，但可对单个房间进行单个

18、the need for high intensity continuous electric lighting in these core areas.句中coupled with 意为“加上， 外加”。 例如：Her name was coupled with his. 她的名字与他的连在一起。 a good deal of discomfort for the occupants.其中for用来指一个活动的接受者或受益者,如：prepared lunch for us. 为我们准备午餐1-15制冷空调专业英语Unit OneNotes to the Text 2.For much of

19、the spring and autumn, as well as the summer, the internal room temperature will be several degrees higher than that outside, and it will be necessary to open windows in order to augment the mechanical ventilation.Lesson 2 句中as well as adv =in addition to 除之外还；和；及（强调的是前面的部分），例如：Im learning French as

20、 wall as English.我学英语之外还学法语。 it will be necessary to open windows,本句属于“It+谓语+动词不定式”这种语形。It作形式主语，to open windows动词不定式作真正的主语。动词不定式、动名词短语或从句在句中起主语作用，而这一部分用词较多时，可用it作为形式主语，放在句首代表其后所说的事实上的、真正的主语，而把真正的主语放在后面。如：It is difficult to climb a mountain.爬山是很艰难的。 1-16制冷空调专业英语Unit OneNotes to the Text 3.There are two reasons why this is acceptable firstLess
