净化实验室的空调通风系统是如何设计的?

来源:http://www.sdrunjing.com/ 日期:2020-02-24 发布人:润静小编
洁净实验室对空调通风系统的选型:用于洁净实验室的空调通风系统有两类,一类是集中式、一类是分散式。前者适用于集群式、多房间、多要求、多功能的洁净实验室,优点是便于管理,远离噪声、降低成本。后者适用于规模较小的洁净实验室或有着单独特性要求的实验室,优点是控制精细、针对性强。
Selection of air conditioning and ventilation system in clean laboratory: there are two types of air conditioning and ventilation system used in clean laboratory, one is centralized, the other is decentralized. The former is suitable for the cluster, multi room, multi requirements, multi-functional clean laboratory, the advantage is easy to manage, far away from noise, reduce costs. The latter is suitable for the smaller scale clean laboratory or the laboratory with separate characteristic requirements, with the advantages of fine control and strong pertinence.
1、选型原则一定要满足净化要求
1. Selection principle must meet purification requirements
在选型实际中,人们往往会根据资金、能耗来选择空调的类型,忽略了选型的根本是为了满足需要,满足净化标准要求。
In the practice of type selection, people often choose the type of air conditioning according to the capital and energy consumption, ignoring that the basic purpose of type selection is to meet the needs and purification standards.
在选型之前,一定要领会净化实验室的用途和实验内容、实验仪器设备、实验对象对空气参数和环境要求的具体事项,然后有的放矢地提出有针对性的净化标准,应该考虑的内容要包括:实验室的面积、楼层高度、实验室的总高度和净化实验室围护后的高度;希望达到的温度、相对湿度、风速、静压、静压差等;实验室内要求的洁净等级、噪声标准、无菌要求等等,综合考虑这些因素后,提出一个适宜的资金要求,从而确定空调通风系统的具体形式和类型。
Before selection, we must understand the purpose and contents of the purification laboratory, the experimental instruments and equipment, and the specific matters of the experimental objects for air parameters and environmental requirements, and then put forward targeted purification standards, which should include: the area of the laboratory, the height of the floor, the total height of the laboratory and the height after the enclosure of the purification laboratory; The expected temperature, relative humidity, wind speed, static pressure, static pressure difference, etc.; the required cleanliness level, noise standard, sterility requirements, etc. in the laboratory, after comprehensive consideration of these factors, a suitable funding requirement is proposed to determine the specific form and type of air conditioning and ventilation system.
2、空调通风系统的选择既要量力而行又要酌情而动
2. The selection of air conditioning and ventilation system should not only be done according to the capacity, but also be made according to the circumstances
洁净实验室之所以洁净,是因为首先使用特殊的工艺阻隔空气与使用空间的自由交流,然后借助于人工的方式把空气处理之后输送到使用空间,当然这里既要输送新风也要输送浊风,所谓浊风就是把使用空间内的空气输送给外界经过处理后使之成为洁净的空气重新输送回使用空间。
The reason why the clean laboratory is clean is that it first uses special technology to block the free communication between the air and the use space, and then delivers the air to the use space by means of manual treatment. Of course, it is necessary to deliver both fresh air and turbid air. The so-called turbid air is to deliver the air in the use space to the outside after treatment to make it clean air again Transport back to use space.
其原理可以用下面的流程图来简示:空气气流→初效空气处理→空调→中效空气处理→风机送风→净化管道→送风口→洁净室→带走尘埃→回风夹道→新风、初效空气处理。
The principle can be illustrated by the following flow chart: air flow → primary air treatment → air conditioning → medium efficiency air treatment → fan air supply → purification pipeline → efficient air supply outlet → clean room → dust removal → return air duct → fresh air and primary air treatment.

用于洁净实验室的空调通风系统主要由空气处理设备、粗高中效过滤器、空气输送设施和局部净化设备组成,这些设备类型各异、作用不同。
The air conditioning and ventilation system used in the clean laboratory is mainly composed of air treatment equipment, coarse and medium efficiency filters, air transmission facilities and local purification equipment, which have different types and functions.
2.1空气处理设备:
2.1 air handling equipment:
空气处理设备一般是由空调器(AHU)、新风机组(MAU)和循环机组(RAU)组成的一整套机组,是空调净化系统常用的空气热湿交换和空气净化处理设备。
Air treatment equipment is generally a complete set of units composed of air conditioner (AHU), fresh air unit (MAU) and circulating unit (RAU). It is a common air heat and humidity exchange and air purification equipment in air conditioning purification system.
适用于具有一定规模的净化实验室,但要求其他过滤器和净化装置的整体配合,投资相对较高。比较小型的实验室空气处理装备是采用分立式的小型设备组成,例如把冷暖空调机作为冷热源,对空气进行温度湿度的简单处理,然后配备风机过滤器单元(FFU)对空气进行洁净处理,是一种比较简易的净化方案。
It is suitable for a certain scale purification laboratory, but requires the overall cooperation of other filters and purification devices, with relatively high investment. Small laboratory air treatment equipment is composed of small vertical equipment. For example, the air conditioner is used as a cold and heat source to simply treat the temperature and humidity of the air, and then equipped with fan filter unit (FFU) to clean the air. It is a simpler purification scheme.
2.2各类空气过滤器:
2.2 various air filters:
按过滤器对空气处理的效率、阻力、容尘量等性能进行分类,可将过滤器划分为粗效、中效、、亚、和超六大类。每种过滤器对尘埃微粒的处理能力不一样,因此它们被应用在各种不的功能段上,如果选用正确、使用合理就能使之发挥作用,否则,就会适得其反。
According to the classification of air treatment efficiency, resistance, dust capacity and other performance of the filter, the filter can be divided into six categories: coarse efficiency, medium efficiency, high efficiency, sub efficiency, high efficiency and super efficiency. Each kind of filter has different ability to deal with dust particles, so they are applied to different functional sections. If they are selected correctly and used reasonably, they will play a role, otherwise, it will be counterproductive.
2.3风机和送风管道:
2.3 fans and air supply pipes:
送风风机一般设在空调机组内,要根据整体管道和空调通风量选择风机,压头较大虽然可以满足克服系统阻力的要求,但会增大能耗和噪声,较好的选择是考虑变频风机,这可能会增大投入但可以使送风量依系统阻力变化自动调节,并且可以做到节能降噪。送风管道要做好保温和降噪,必要时应加增消声装置。
The air supply fan is generally set in the air conditioning unit. The fan shall be selected according to the overall pipeline and air conditioning ventilation volume. The larger pressure head can meet the requirements of overcoming the system resistance, but it will increase the energy consumption and noise. The better choice is to consider the variable frequency fan, which may increase the input, but can make the air supply automatically adjust according to the system resistance change, and can achieve energy conservation and noise reduction. Heat preservation and noise reduction shall be done for the air supply pipeline, and additional silencing devices shall be added if necessary.
2.4局部净化设备:
2.4 local purification equipment:
包括风淋室、自净器、洁净工作台和电子灭菌装置等风淋室是在洁净实验室入口处单独设置一个局部洁净室,当打开风淋室的门进入到风淋室后,经过中效和过滤器过滤的空气气流,其速率会达到≥25m/s的高速,则进入实验室的人员和设备表面附着的尘埃微粒会被吹落净化,是洁净实验室的必备设施。其他局部净化设备要根据不同的净化要求和实验室类型酌情选择。
The air shower room, including the air shower room, self purifier, clean bench and electronic sterilization device, is a local clean room set at the entrance of the clean laboratory. When the door of the air shower room is opened and enters the air shower room, the air flow filtered by the medium efficiency and high efficiency filters will reach a speed of ≥ 25m / s, and the dust particles attached to the surface of the personnel and equipment entering the laboratory will It will be blown down and purified. It is a necessary facility for a clean laboratory. Other local purification equipment shall be selected according to different purification requirements and laboratory types.
