课程名称：HVAC基础：制冷循环概述：初学者指南 课程概述： 本课程旨在介绍制冷循环，这是空调和制冷的基础。内容涵盖制冷循环的四个主要组成部分及其功能，讲解制冷循环如何吸收和排放热量，如何产生冷空气以冷却空间，以及实现这一过程所需的压力和温度。 受益人群： 对于没有HVAC经验的初学者，本课程将大有裨益。课程以基本的类比开始，帮助学生理解制冷循环及其主要组成部分的功能，随后探讨压力与温度之间的关系。课程后期还考虑基本的故障排除。 HVAC学徒同样可以从本课程中受益，因为这些知识可以补充他们已在学习的内容，帮助学生学会正确的方法来检查、诊断和理解制冷循环，从而避免养成不良习惯。 经验丰富的HVAC专业人员也可以通过本课程填补知识空白，帮助他们摆脱一些可能阻碍进步的不良习惯和思维方式。虽然本课程不包含高级诊断，但为建立技能提供了坚实的基础。 授课方式： 课程包括讲解和幻灯片演示，辅以视觉辅助材料，旨在保持学生的参与感。同时，也包含实地拍摄的视频，展示如何进行空气温度、制冷剂压力和温度的读数，以及如何计算过热和过冷。 强调重复： 课程设计以浅显的知识切入，逐步深入理解每个细节，通过反复学习加深学生的知识记忆。 每节课后的测验： 每节课都有测验，测验问题的答案可以在课程中找到，以帮助学生在进入下一节课前评估自身理解水平。 课程资料： 本课程提供了R410A压力/温度图和制冷循环原理，总结课程内容并帮助学生在实际应用中作为快速指南。 期末考试： 期末考试的问题旨在揭示学生对课程内容的理解深度。学生需获得70%或以上的分数才能通过课程。考试的答案可以在课程内容内外找到，类似于HVAC专业人员在实际工作中寻求可靠答案的过程。
A Beginner's GuideThis course is designed as an introduction to the refrigeration cycle, which is the basis for air conditioning and refrigeration. It covers the (4) main components of the refrigeration cycle and their purpose. It explains how the refrigeration cycle absorbs and rejects heat, how it makes cold air to cool a space and what pressures and temperatures are required to accomplish this.Who Can Benefit From This Course?Beginners without any HVAC experience will greatly benefit from this course. It starts with a basic analogy to help the student learn what the refrigeration cycle is and what its main components do. It then goes into pressure and temperature relationships. Towards the end of the course, basic troubleshooting is considered.HVAC apprentices will also benefit from this course as this knowledge will compliment what they are already learning. It also helps the student to learn the proper way to check, diagnose and think about the the refrigeration cycle so bad habits are not learned.Experienced HVAC professionals can also benefit from this course to fill in gaps in knowledge and help them unlearn some bad habits and thinking processes that may impede progress. While this course does not include advanced diagnosis, it gives you a solid foundation to build your skills with accurate knowledge.Lectures and Video DemonstrationThe course includes a lecture with slides and visual aids that keep the student engaged. It also includes videos taken in the field to demonstrate how to take air temperature, refrigerant pressure and temperature readings and how to calculate superheat and subcooling.Repetition For EmphasisThe course is design in a way that starts the student off with superficial knowledge. Each course repeats the refrigeration cycle, adding more understanding to details. This repetition sounds down the knowledge into the student.Quiz After Every LessonEvery lesson has a quiz including where the answer can be found in the course so the student can gauge his/ her own understanding before advancing to the next lesson.Course HandoutsIncluded in this course are: R410A Pressure/ Temperature ChartRefrigeration Cycle Principles which summarize the course content into a single quick- guide that the student can use in the field.Final ExamThe final exam questions are worded to reveal the depth of understanding the student as after taking the course. A 70% or more grade allows the student to pass the class. Answers to the exam can be found in or outside course content provided, similar to an HVAC professional seeking an answer in the field from any reliable source available to him/ her.
