物业管理英语第十一讲Heating, Ventilation, Air Conditioning

2006-07-29 10:02

  In many parts of the U.S. and the world, the engineering staff must keep the property heated for a good part of the year. In the winter, this means simply maintaining a comfortable, even temperature. During spring and fall,however, it is desirable to take off the chill without overheating the building - no small task if the heat is manually controlled.

  Hot water heating systems are still used in some properties, but steam systems are more common. While many properties purchase their steam from public utilities, others operate their own boilers. Coal-stoked boilers are dirty. Gas or oil burners are clean, but they require additional employees. Buying steam reduces the number of employees needed to maintain the boilers. So the engineering crew must have the technical knowledge and skill to handle them.

  Maintaining a heating plant may appear to be simple routine work, but,in reality, it requires highly technical knowledge. Burners must be maintained and repaired, thermostats must be kept in good working order, radiators and valves need attention. New types of controls are being developed that will bring heating closer to an automatic operation, but the automated repair and maintenance engineer just does not exist and probably never will.

  Another responsibility of the engineering division is the ventilation and air conditioning system. Regular changes of air are required, and it takes machinery to provide this. The public today demands air conditioning in all first-class properties. A central system provides a central point for maintenance and repair.

  Computer and other electronic devices called energy management system (EMS)

  have been developed to control peak power demand; regulate the heating,ventilating, and air conditioning throughout the building as needed; and control every aspect of energy usage in the operation .

  These systems are all technically very complex and require a knowledgeable and experienced staff to operate and maintain underscores the need for better training and education of the engineering staff.

  Useful Expressions

  take off 拿走,取消

  in reality 实际上,事实上

  close to 接近于,几乎

  Notes

  1. …the engineering staff must keep the property heated for a good part of the year.过去分词heated在句子中作宾语补足语,因为是人物业供暖,有被动的意思,故用过去分词。例如:

  They have made rules to keep the property cleaned.

  for a good part of the year可译为:一年的大部分时间

  good意为“颇,相当的”。例如:

  It will take me a good five hours to write such an article.写这样一篇文章足足要花五个小时。

  2. …it is desirable to take off the chill without overheating the building - no small task if the heat is manually controlled. no small task对前句中的to take off the chill…作进一步解释。意为“这可不是小任务”。No置于名词或形容词之前,意为“一点也不是,绝不是”。例如:

  He is no gentleman.他根本不是个绅士。

  She left her niece no small fortune.她留给侄女一笔庞大的遗产。

  3. coal-stoked boiler燃煤锅炉

  4. New types of controls are being developed that will bring heating closer to an automatic operation…

  此句中含有一个定语从句that will bring heating…,修饰new types of controls,由于修辞的需要,将定语从句后置,可避免头重脚轻。例如:

  New houses will be built that can be used to settle refuges.

  5. but the automated repair and maintenance engineer just does not exist and probably never will.

  and后的并列成份maintenance与前面的repair修饰的是同一个主语engineer, will后省略了谓语动词exist,由于该部分是省略形式,其副词never就放在了助动词will的前面。

  6. control peak power demand控制高峰时期的用电需求

  7. regulate the heating, ventilating, and air conditioning throughout the building as needed…。

  在必要时调节整栋建筑的供暖,通风以及空调的使用。as作连词,引导状语从句,此处省略了主语和系动词。
