英语翻译
4.3.1 Compressor head reduction reduces the pumping effort required by the compressor which is accomplished either by raising chilled water temperature or by lowering condensed water temperature.Reducing condensor waste in,or chilled water out,will save about 1.5 to 2 % compressor motor energy per one deg .F of change.
4.3.2 Using Control Logic for chilled water reset and condenser water reset.
4.3.3 Controlling chiller electric demand through shutdown of selected,non - critical air handlers using chilled water and limiting the opening of suction inlet wanes.
4.3.4 Chiller sequencing and local control is used in plants having multiple chillers.Independent on type or size there is an optimum combination of chillers,pumps and towers for each increment of plant loads.
4.3.5 Methods like reducing chiller energy by rehabilitation,free cooling cycles,chilled water main revisions and spot cooling might be used depending on plant conditions.
4.4 Boiler Controls：
Boiler generates steam or hot water for the consumption for space heating,air handlers,domestic water and various processes.Three main fue1 conservation opportunities could be exploited through proper controls.
4.4.1 Improvement of combustion efficiency.This is done through fuel automizing & mixing with combustion air,Air – Fuel ratio adjustment,control of stack temperature and flue gas composition.
4.4.2 Reduction of losses:External to the Combustion Chambers to achieve this the considerable steps are :Preheating combustion air and feed water with flue gas; Installation of dampers to prevent off-cycle stack loss ; Drawing combustion air from hottest point within the room and putting extra insulation in some specific areas.
4.4.3 Better control of the furnace I Boiler:Burners are retrofitted to achieve better atomization and mixing of air and fuel.This ensures complete combustion,less soot / smoke,less cleaning and better efficiency.Moreover closer control in spaces without wasteful overshooting of desired control point will help in cost control.
4.5 Lighting Levels & Lighting Controls:
Lighting levels can be reduced to an appropriate level consistent with the use of that particular space like 50 foot candles at occupied workstation; 30 foot-candles in work areas and less than 10 foot candles in areas such as hallways and corridors.
Lighting Control is done in various forms like lights on only when and where necessary automatic switching with local overrides,modulating the amount of light provided to an area through use of special type of sensors combined with a computerized building automation system
Other steps like reducing the cooling load and selecting efficient light sources could also be considered.

.3.1压缩机头减少降低了泵的努力所需要完成的压缩机是通过提高冷却水温度或通过降低冷凝水的温度.减少冷凝废物,或冷却水时,将节省约1.5至2 ％的压缩机电机能源每度.楼的变化.4.3.2使用控制逻辑的冷却水和冷凝水重置重置.4.3.3机组电气控制需求通过关闭选定的,非-关键空气处理使用冷却水,并限制开放吸进减弱.4.3.4机组顺序和局部控制中使用的植物有多种冷水.独立的类型或大小有一个最佳组合机组,水泵和水塔每增加植物负载.4.3.5制冷方法,减少能源的康复,自由冷却循环,冷却水的主要修改和现场冷却可用于取决于工厂的条件.
4.4锅炉控制：锅炉产生蒸汽或热水的消费空间暖气,空气处理,生活用水及各种进程.三个主要fue1养护可以利用的机会,通过适当的控制.
4.4.1提高燃烧效率.这是通过燃料automizing与空气混合燃烧,空气-燃料的比例调整,控制堆温度和烟气成分.
4.4.2减少损失：外部燃烧室实现这一目标有相当大的步骤：预热助燃空气和给水与烟气;安装阻尼器,以防止非周期栈损失;绘图燃烧空气从最热的房间内并把额外的绝缘在一些具体领域.
4.4.3更好地控制锅炉炉膛我：燃烧器的改造,以实现更好的雾化和混合的空气和燃料.这将确保完全燃烧,减少烟尘/烟,少的清洁和更好的效率.此外更密切控制过度浪费空间不理想的控制点,将有助于控制成本.
4.5照明水平及照明控制：照明水平可以降低到适当水平符合使用该特定空间像50英尺的蜡烛在被占领的工作站; 30英尺的蜡烛在工作领域和不到10英尺的蜡烛等领域的走廊和走廊.照明控制工作是在各种形式像灯只在必要时自动切换与当地覆写,调制的光量的地区提供了通过使用特殊类型的传感器结合计算机化楼宇自动化系统.
