Ventilation and air conditioning engineering is composed of ventilation system and air conditioning system. Laboratory planning sterile laboratory clean laboratory biosafety laboratory construction scheme includes: building layout and decoration, air conditioning, water supply and drainage, gas supply, electrical design, centralized control, security, construction technology, testing, training and other aspects. The air conditioning system of laboratory furniture is the key to the safe operation of clean laboratory and biosafety laboratory.

由于洁净实验室—生物安全实验室内操作对象是危险性的微生物，对人体、动植物或环境具有危害，必须通过采用合理的空气调节系统，保持洁净实验室—生物安全实验室的相对负压环境无论何时都不被破坏，以保证实验室内危险性微生物不能向外部环境中扩散。实验室装修设计的通风系统由排气扇、风道、风道部件、消声器等组成。

Because the operating objects of clean laboratory biosafety laboratory are dangerous microorganisms, which are harmful to human body, animals and plants or the environment, it is necessary to adopt reasonable air conditioning system to keep the relative negative pressure environment between clean laboratory and biosafety laboratory from being damaged at any time, so as to ensure that dangerous microorganisms in the laboratory can not spread to the external environment. The ventilation system of laboratory decoration design is composed of exhaust fan, air duct, air duct components, muffler, etc.

空调系统通过空调冷、热源、空气处理器、空气输送管道、空调等方式输送和分配到室内温度、湿度、气流速度和净空。

The air conditioning system transmits and distributes the indoor temperature, humidity, air velocity and clearance through air conditioning cold, heat source, air processor, air delivery pipeline and air conditioning.

实验室装修设计的通风空调工程由通风系统和空调系统组成。实验室通风系统由送风排风扇、风管部件、消声器等组成。该空调系统由空调冷热源、空气处理器、输气管道输送与分配、室内温度、湿度、气流速度及洁净度的自动控制与调节等部分组成。
