## 住宅暖通空调设计基础 - Coursera 课程总结 本课程专注于加拿大典型独栋、半独立式及联排低层住宅的暖通空调（HVAC）设计技术。课程内容涵盖了制热、制冷和通风负荷的计算，并为HVAC空气系统设计奠定基础。 课程伊始，将介绍基础建筑构件以及常见的低层住宅类型。随后，详细讲解如何计算建筑地基传导热损失、建筑围护结构（包括：楼板、屋顶、地面、墙体、门、窗及天窗）的传导热损失和太阳得热。课程还将探讨室内人员和设备产生的得热，以及通风和渗透性制冷/制热负荷的计算方法。 通过问答环节，学生将获得一个Excel模板，用于计算案例住宅的负荷以及进行空气系统设计。该模板由拥有加拿大安大略省数百个住宅HVAC设计经验的讲师开发和使用，其中包含了大量的负荷计算公式，供学生独立练习。尽管模板基础是基于安大略省建筑规范及特定的节能和通风要求，并且公式采用英制（IP）单位，但它易于适配全球任何地理位置，课程中也将解释如何进行不同气候区的参数替换。 为满足全球学生的学习需求，课程中的所有计算均同时使用英制（IP）和国际单位制（SI）。课程鼓励学生查找特定住宅所在地的冬季和夏季设计温度、室内设计温度、当地建筑规范、通风规范以及HVAC设备能效要求，并据此进行HVAC系统设计。若特定气候区或地区缺乏建筑规范和天气数据，课程也将提供推荐的最低性能要求数据。 完成本课程后，学员应能理解住宅HVAC系统，进行基础负荷计算，为HVAC设备选型，并设计相应的HVAC系统，以保障居住者的健康与舒适。课程还将推荐最低通风要求，以控制室内空气质量，保障居住者的健康。
This course explores the residential house HVAC design technique for typical detached, semi-detached and townhouse low-rise residential houses in Canada. The course includes both heating, Air Conditioning and ventilation (HVAC) load calculation, and prepares the basic knowledge for the HVAC air system design.The course starts by presenting the basic building elements and common types of low rise residential homes, and explain the method of calculating building foundation conductive heat loss, building envelope (exposed ceiling, roof, floor, wall, door, window and skylights) conductive heat loss and solar heat gain. The course further explores the occupants' heat gain and equipment heat gain, and the method for calculating ventilation and infiltration heating and cooling load.Through the Q & A section, the students will be provided with an excel template for load calculation and air system design of a sample home. The template is developed and used by the instructor who has successfully completed HVAC design for hundreds of residential houses across Ontario Canada. There are lots of load calculation formulas that will be included in the Microsoft Excel template for students to practise load calculation on their own. The air system design portion is also included in the temperate provided to the students in the basic course, but lecturing of the air system design will be left for the intermediate and advanced HVAC design course.Despite the template being developed is based on Ontario building code with specific energy efficiency and ventilation requirements in Ontario, and despite all the formulas being in the imperial (IP) format, this Excel template may be easily adopted for any geographic location across the globe. The parameter substitution for all different climate zones will be explained.This course is offered to students worldwide, so all the calculations will be performed in both unit systems: IP (imperial) and SI (metric). The students will be encouraged to find out the winter and summer design temperature and indoor design temperature for the specific location of the subject house, as well as local building code, ventilation code and HVAC equipment energy efficiency requirements from the specific AHJ (authority having jurisdiction), and design the HVAC systems accordingly. In case the building code and weather date is not available for some climate zones or regions, the course will also provide the students with recommended minimum requirement data.Upon completion of this course, the students are expected to be able to understand house HVAC systems, to perform basic load calculation, to size the HVAC equipment and to design the HVAC system accordingly for occupants' health and comfort living in their residential homes. The minimum ventilation requirement will be recommended to control the indoor air quality for occupants' health.
