    手术室装修之洁净室节能的技术
    Energy-saving Technology of Clean Room in Operating Room Decoration
    1.换气次数
    1. Frequency of ventilation
    干净室维持一定的空气流量来坚持清洁度和颗粒数。流量依据每小时的换气次数来确定,同时这也决议了风机尺寸.修建构型和能量耗费。在坚持干净度的前提条件下,空气流速的降低可以降低建造及能耗本钱。换气次数降低20%就可以使风机的尺寸降低50%。空气干净度比浪费能耗更重要,但是新的研讨效果曾经有降低干净本钱的记载了。
    The clean room maintains a certain air flow to maintain cleanliness and particle number. Flow is determined by the number of ventilation per hour, which also determines the size of the fan, construction configuration and energy consumption. On the premise of maintaining cleanliness, the reduction of air velocity can reduce the cost of construction and energy consumption. Reducing the number of ventilation by 20% can reduce the size of the fan by 50%. Air cleanliness is more important than wasting energy, but new research results have been documented to reduce cleanliness costs.
    关于换气次数还没有达成共识。许多准绳都已过时,是树立在老观念上,采用低效的空气过滤器。调查显示,ISO第5级规范的干净室引荐的换气次数变化范围是从250到700以上。
    There is no consensus on the number of breathing cycles. Many of the criteria are out of date and are based on the old idea of using inefficient air filters. According to the survey, the recommended ventilation times for clean rooms in ISO Level 5 specification ranged from 250 to 700.
    2.马达效率
    2. Motor efficiency
    马达耗费了干净室的大局部电能。延续运转的马达每月耗费少量的电力。适外地进步效率.适外地调理尺寸,在创新后,经济效果多半是不错的。效率添加几个百分点,利润就可添加。
    The motor consumes most of the electricity in the clean room. Continuous motors consume a small amount of electricity each month. Suitable for the improvement of efficiency in the field. Suitable for the adjustment of size in the field. After innovation, the economic effect is mostly good. If efficiency is increased by a few percentage points, profits can be added.
    运用无效的马达,不一定会破费太多。率意味着小,在改动马达的尺寸之前先尽量减小负荷。在输入质变化时,应用变速驱动(VSD)可以进步操作效率。
    Using ineffective motors does not necessarily cost too much. Efficiency means small, reducing the load as much as possible before changing the size of the motor. When the input quality changes, the application of variable speed drive (VSD) can improve operation efficiency.
    3.双温度冷冻循环
    3. Dual Temperature Freezing Cycle
    设计人员可以运用并联循环管路,将他们成两个子零碎,这样可以在需求大冷量的时分,冷冻机可以任务在绝对不很苛刻的条件下。用公用冷冻机停止中等温度的循环(例如55oF到65oF),它的运作是针对冷冻水的温度停止优化的,可以满足工厂的大局部需求。另一个较小的冷冻机提供温度较低的循环(例如:39oF到43oF),可以满足负荷中要求苛刻的局部。
    Designers can use parallel circulating pipes to break them into two pieces, so that refrigerators can work under absolutely no harsh conditions when they need large amounts of cold. Stop the medium temperature cycle (e.g. 55oF to 65oF) with a public refrigerator. Its operation is optimized to stop the temperature of chilled water, which can meet most of the plant's needs. Another smaller efficient refrigerator provides a lower temperature cycle (e.g. 39oF to 43oF) to meet the demanding parts of the load.

    这个方案可以迅速添加整个冷冻机机组的效率进步百分之二十五或更多。关于相反容量的冷冻机,低温任务要比高温任务破费小得多。
    This scheme can quickly add 25% or more improvement in the efficiency of the whole refrigeration unit. For refrigerators with opposite capacity, low-temperature tasks cost much less than high-temperature tasks.
    4.自在冷却
    4. Free Cooling
    运用里面的空气停止冷却是经济的,在商业大楼失掉普遍采用。另外一种“自在冷却”方案适用于需求恒定的冷冻水以及风机盘管的零碎,比方干净室。
    It is economical to use the air inside to stop cooling, which is commonly used in commercial buildings. Another "self-cooling" scheme is suitable for chilled water with constant demand and fragments of fan coil units, such as clean rooms.
    自在冷却技术间接应用处在高温或低湿度环境中的冷却塔制造冷冻水,增加或取代冷冻机的运用。依据天气的变化,运用自在冷却零碎可以把冷却零碎的耗能增加到非常之一(从0.5千瓦/冷吨增加到0.05千瓦/冷吨)。
    Free cooling technology indirectly applies cooling towers in high or low humidity environments to produce chilled water, increasing or replacing the use of refrigerators. According to the change of weather, the use of self-cooling fragments can increase the energy consumption of cooling fragments to one tenth (from 0.5 kW/t to 0.05 kW/t).
    间接与工艺负荷停止热交流,可以使自在冷却技术应用里面温度较高的大气,要比用在二级或许三级热交流零碎停止热交流的工夫长出若干个小时。由板式热交流器分隔开来的冷却水和冷凝水之间的温差很接近(比方只要2oF)。当温度和湿度相当低时,冷却塔可以独立运转,无需风机。依据温湿图,很多中央每年有很多的工夫都可以停止自在冷却。
    By indirectly stopping heat exchange with process load, the higher temperature atmosphere in the application of self-cooling technology can take several hours longer than the time spent on stopping heat exchange fragmentally in secondary or tertiary heat exchanges. The temperature difference between the cooling water and the condensate separated by the plate heat exchanger is very close (for example, only 2oF). When the temperature and humidity are quite low, the cooling tower can operate independently without fan. According to the temperature and humidity chart, many central authorities have a lot of time each year to stop self-cooling.
    5.离心式紧缩机
    5. Centrifugal Compressor
    空气紧缩机的改良浪费了少量动力。离心式紧缩机是无油的,比螺杆式紧缩机的效率高很多。但是离心式紧缩机不能空转,这使得他们在负载低的状况下效率很低。无效和经济的方法是离心式和螺杆式紧缩机两者结合运用。选用离心机组满足根本负荷,再用小一些的螺杆式机组满足峰值负荷。紧缩机组应该配有热回收零碎。
    The improvement of the air compressor wastes a small amount of power. Centrifugal compressor is oil-free, much more efficient than screw compressor. But centrifugal compressors can not idle, which makes them inefficient under low load conditions. The ineffective and economical method is the combination of centrifugal and screw compressors. Centrifugal units are selected to meet the basic load, and smaller screw units are used to meet the peak load. Compression units should be equipped with heat recovery scraps.
    另一种方案是整个现场用的离心式紧缩机作爲一个大的紧缩空气安装,外加大的储气罐和衔接管道作爲缓冲器。这样可以保证整个工厂维持一个恒定载荷,加重加载与卸载对设备的损耗,并且降低能量糜费。
    Another option is to install a high-efficiency centrifugal compressor as a large compressed air throughout the site, with an extra enlarged gas storage tank and a connecting pipe as a buffer. This ensures that the whole plant maintains a constant load, increases the loss of equipment caused by loading and unloading, and reduces energy wastage.
