objectives

HVAC field in general is more difficult than other mechanical fields such as Fire Fighting or Plumbing, that because:

  1. The main aim of HVAC is achieve comfort for people, or meet the needs of some particular applications, and this depends one a lot of conditions and factors
  2. Deal with several materials and phases. Where there are water, air, and a lot of types of refrigerant
  3. In other fields usually dealing is been with incompressible fluids, but in HVAC there is an air and it is compressible, so here more difficult occurs
  4. Wide range of options are available for each case, unlike other fields such that there are constant requirements have not to be changed
  5. Standards and references that used in this field are a lot comparison with Fire Fighting or Plumbing systems

This course is design course, so participant needs to know and understand a lot of fluid characteristics, whom this course is included

مجال التكييف والتبريد بشكل عام أكثر صعوبة من باقي المجالات الميكانيكية مثل مكافحة الحريق والسمكرة, وذلك بسبب :

  1. الهدف الرئيس من أنظمة التكييف والتبريد هو تحقيق الراحة للناس, أو تلبية احتياجات تطبيقات معينة, وهذا يعتمد على الكثير من الظروف والعوامل
  2. التعمال مع عدة مواد وأطوار, حيث هنالك مياه, هواء, والعديد من أنواع مواد التبريد
  3. في المجالات الأخرى يتم التعمال مع موائع غير قابلة للانضغاط, لكن في أنظمة التكييف والتبريد هنالك هواء, وهو قابل للانضغاط, مما يؤدي إلى مزيد من الصعوبة
  4. لدينا مجال واسع من الخيارات والبدائل لكل حالة, على عكس باقي المجالات حيث تكون هنالك متطلبات ثابتة لا يمكن تغييرها
  5. المعايير والمراجع المستخدمة في هذا المجال كثيرة ومتعددة مقارنة بأنظمة إطفاء الحريق والسمكرة

هذه الدورة هي دورة تصميمية, لذلك فالمشارك يحتاج أن يعرف ويفهم الكثير من خصائص الموائع, والتي تم تضمينها في هذه الدورة
