课程名称：HVAC：室内空气质量、过滤器与洁净室基础介绍 课程概述：该课程旨在帮助任何对暖通空调（HVAC）感兴趣的人了解三个重要主题：1. 室内空气质量 2. HVAC与洁净室中的过滤器 3. 洁净室。 主要讲座内容： 1. 室内空气质量简介 2. 污染物来源 3. 空气过滤器简介 4. HEPA和ULPA过滤器 5. 空气过滤器选择、MERV值及典型应用 6. 洁净室简介 7. 洁净室的一些设计方面 室内空气质量（IAQ）指建筑物内外的空气质量，尤其与居住者的健康和舒适度相关。室内污染源释放气体或颗粒是导致室内空气质量问题的主要原因。通风不足会通过未能提供足够的户外空气来稀释室内污染物排放，并未能将室内污染物排出区域，从而增加室内污染物浓度。高温和高湿度水平也会增加某些污染物的浓度。过滤器和维持适当通风及源头控制是控制室内空气质量的策略之一。 家庭暖通空调系统中的过滤器发挥着重要作用，它们过滤尘埃、花粉、宠物皮屑等小颗粒，以保护您和您的家人呼吸的空气。这些颗粒被困在过滤器中，以防止再次被循环回家中。MERV值越高，过滤器的有效性越强。过滤器还对保持系统免受可能造成损害的大颗粒至关重要，因此要确保始终使用正确类型的过滤器，并在其变脏时更换。 洁净室旨在维持极低的颗粒物（如灰尘、空气中生物体或蒸汽化颗粒）水平。 通过学习这些概念，学生在HVAC行业的就业机会将大大增加，也可以自主创业，满足室内空气质量的需求。
The course is designed to help anyone interested in HVAC to learn about the three important topics1.Indoor air quality 2.Filters in HVAC and clean rooms3.Clean rooms Lecture 1:Introduction to indoor air qualityLecture 2:Sources of ContaminantsLecture 3:Introduction to Air FiltersLecture 4:HEPA ,ULPA filtersLecture 5:Air filter selection ,MERV value and typical applicationsLecture 6:Introduction to clean roomsLecture 7:Clean rooms some design aspectsIndoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the area. High temperature and humidity levels can also increase concentrations of some pollutants.Filters and maintaining adequate ventilation along with source control are the strategies of controlling indoor air quality. The HVAC filters used in your home's heating and cooling system have an important job to do. They filter dust, pollen, pet dander, and other small particles out of the air that you and your family breathe. These particles are trapped in the filter to prevent them from being recirculated throughout your home. The higher the MERV rating, the more effective the filter will be.Filters also play an important part in keeping your system free from larger particles that could damage it. Therefore, you want to make sure that you are always using the right type of filter and change it when it is dirty. Here are the different types of filters available for residential HVAC systems.Cleanrooms are designed to maintain extremely low levels of particulates, such as dust, airborne organisms, or vaporised particlesAfter learning these concepts students would be more employable in HVAC Industry or self employed to cater to the needs of indoor air quality
