بسم  الله  الرحمن  الرحيم  
mep,blogger,rules,قواعر  الاشتراك




اولا  احب  اشكر  كل  المهندسين الي بيثقوا في المدونه وبيتعاملوا  معاها  

من فتره بسيطه تم  اضافة  اداه للمراسلات  بحيث  ان اي  مهندس حابب  يراسلني   عن  طريقها  

((  موجوده   دايما اسفل الصفحة باسم اتصل بنا   )) 


يمكن استخدام  الاداه  لطلب  كتاب  او  دعم  فني  او  عرض  تصميم   

حتي  لو   في شغل محتاج مصمم  ليه ممكن   نعمله  

احنا مجموعه من المهندسين ان  شاء  الله نكون  علي قدر  الثقه دي 


لكن  في  الفتره  دي جت  لي  بعض  المراسلات الايميل  المرفق  فيها  به  خطأ فالبتالي   مقدرناش  نرد علي   الطلب  


برجاء  اي  حد محتاج اي  حاجه  يتأكد  من  الايميل  والبيانات   المرفقه  

شكرا   جزيلا

Purpose. 


The purpose of this standard is to provide a practical safe working area for employees relative to the hazards arising from the use of electricity

Scope.

(A) Covered.

 This standard addresses electrical safety-related work practices, safety-related maintenance requirements, and other administrative controls for employee workplaces that are necessary for the practical safeguarding of employees relative to the hazards associated with electrical energy during activities such as the installation, removal, inspection, operation, maintenance, and demolition of electric conductors, electric equipment,signaling and communications conductors and equipment, and raceways. This standard also includes safe work practices for employees performing other work activities that can expose them to electrical hazards as well as safe work practices for the following:

(1) Installation of conductors and equipment that connect to the supply of electricity
(2) Installations used by the electric utility, such as office buildings, warehouses, garages, machine shops, and recreational buildings that are not an integral part of a
generating plant, substation, or control center Informational Note: This standard addresses safety of workers whose job responsibilities involve interaction with energized electrical equipment and systems with potential exposure to electrical hazards. Concepts in this standard are often adapted to other workers whose exposure to electrical hazards is unintentional or not recognized as part of their job responsibilities. The highest risk for injury from electrical hazards for other workers involve unintentional contact with overhead power lines and electric shock from machines, tools, and appliances.

(B) Not Covered.

 This standard does not cover safety-related work practices for the following:
(1) Installations in ships, watercraft other than floating buildings, railway rolling stock, aircraft, or automotive vehicles other than mobile homes and recreational vehicles

(2) Installations of railways for generation, transformation, transmission, or distribution of power used exclusively for operation of rolling stock or installations used exclusively for signaling and communications purposes
(3) Installations of communications equipment under the exclusive control of communications utilities located outdoors or in building spaces used exclusively for such
installations
(4) Installations under the exclusive control of an electric utility where such installations:
a. Consist of service drops or service laterals, and associated metering, or
b. Are located in legally established easements or rights of- way designated by or recognized by public service commissions, utility commissions, or other regulatory agencies having jurisdiction for such installations, or
c. Are on property owned or leased by the electric utility for the purpose of communications, metering, generation, control, transformation, transmission, or distribution of electric energy, or
d. Are located by other written agreements either designated by or recognized by public service commissions, utility commissions, or other regulatory agencies having jurisdiction for such installations. These written agreements shall be limited to installations for the purpose of communications, metering, generation, control, transformation, transmission, or distribution of electric energy where legally established easements or rights-of-way cannot be obtained. These installations shall be limited to federal lands, Native American reservations through the U.S. Department of the Interior Bureau of Indian Affairs, military bases, lands controlled by port authorities and state agencies and departments, and lands owned by railroads

Thermal Environmental Conditions for

Human Occupancy

ANSI/ASHRAE Standard 55-2017 ;Thermal Environmental Conditions for Human Occupancy;comfort ;ASHRAE; comfort

1. PURPOSE

The purpose of this standard is to specify the combinations of indoor thermal environmental factors and personal factors that will produce thermal environmental conditions acceptable to a majority of the occupants within the space


2. SCOPE

2.1 The environmental factors addressed in this standard are temperature, thermal radiation, humidity, and air speed; the personal factors are those of activity and clothing.

2.2 It is intended that all of the criteria in this standard be applied together, as comfort in the indoor environment is complex and responds to the interaction of all of the factors that are addressed herein.2.3 This standard specifies thermal environmental conditions acceptable for healthy adults at atmospheric pressure equivalent to altitudes up to 3000 m (10,000 ft) in indoor spaces designed for human occupancy for periods not less than 15 minutes.

2.4 This standard does not address such nonthermal environmental factors as air quality, acoustics, and illumination or other physical, chemical, or biological space contaminants that may affect comfort or health.2.5 This standard shall not be used to override any safety, health, or critical process requirements

medical gas ; nfpa 99 ; Afnor ; nf 90-116 ; الغازات  الطبيه  ك mep ;HTM 02-01  part A
الغازات الطبيه  من اهم  مجالات  MEP  والي بتكون  موجوده  في  اغلب  المستشفيات  الحديثه  وهي  عباره  عن  محطة  تمد  المستشفي بالغازات  الطبيه  اللازمه  للمرضي  وغرف  العمليات  والتي  تشمل  اكسجين  , الهواء  الطبي , الهواء الجراحي  , وغيرها

اي مشروع  بيتم  تصميم  الغازات  الكبيه  لازم  بيمر  بعدة  خطوات 
اولا  تحدد احتيجات  كل  حيز  من المستشفي للغازات 
ثانيا البدأ في توزيع  مخارج  الغازات  في كل  غرف
ثالثا توزيع AVSU    ومحابس العزل  ولوح الانذار 
رابعا  رسم  شبكة المواسير 
خامسا  تحديد  سعة محطة الامداد 

كل  هذه  الخطوات  يتم  تنفيذها بناء  علي  كود  من الاكواد  المعتبره  مثل  HTM 02-01  part A
 وهو  الكود  الاشهر   وايضا  يوجد  الكود  الالماني   والكود  الفرنسيي  AFnor NF 90-116
وطبعا  NFPA 99
