Air Conditioning System Kya Hota Hai AC In Urdu

What Is Air Conditioner In Hindi




AC ka pura naam Air Conditioner hai jise short term AC kaha jata hai. Air conditioner aik aisa system ya machine hai jo hawa ko aam taur par aik refrigeration cycle ke sath jahan par garam hawa ko khatam kiya jata hai aur usay thandi hawa ke sath aur ziyada num hawa mein tabdeel kiya jata hai. AC ki construction mein heating, ventilation aur air conditioning ka aik mukamal system jise short term mein HVAC bhi kaha jata hai fit hota hai. AC ghar mein ho ya offices mein aur ya phir Car ya dusri Vehicles mein AC ka maqsad yehi hota hai kay garam hawa ko thanda kar diya jaye.

History of Air Conditioner

19th century mein British Scientist aur Inventor Michael Faraday ne discover kiya kay ammonia ko liquid mein badal kar hawa ko thanda kiya ja sakta hai jab liquefied ammonia ko liquid sey bukharat mein badla ja sakta ho. 1842 mein Philippines Physician Dr. John Gorrie ne ice banane ke liye compressor ki technology ko istemal kiya jo wo apne patients ko thandi hawa dene ke liye istemal karta tha. Usnay akhir kaar ye umeed lagai kay ice-making machine ke zariye buildings ka temperature aur puray city ka temperature centralized air conditioning units se thanda kiya ja sakta hai.

Air Conditoning Applications

Air Conditioning Engineers wasee taur par air conditioning applications ko comfort aur process mein taqseem karte hain.

Comfort Applications

Comfort applications ka maqsad indoor environment ko aik jesa rakhna hai bahir ka mahol jesa marzi ho weather condition jesi marzi ho lekin indoor heat loads ko control karna hai.

Process Applications




Process applications ka maqsad insanon ko thandi hawa dena nahi hota balkay industrial ya phir commercial process ko suitable environment mein rakhna hota hai takay industry mein lagi hui machines heat loads ki wajah sey kharab na ho jaye ya phir weather condition ki wajah se koi machine kharab na ho isi comfort range mein conditions ki requirement ko pura karna hota hai lekin comfort applications ki tarah nahin jis mein insaano ko thandi hawa chahiye ye sirf environment ko normal rakhne ke liye use hoti hain.

Process Applications ki misaal darj zail hain:

Hospital operating rooms jahan par hawa ko high level par filter kiya jata hai takay infection ki risk ko kam kiya ja sake aur patient ki dehydration ko limit mein rakhne ke liye humidity ko control kiya jata hai. Agarcha temperatures aksar comfort range mein hote hain kuch specialist procedures jaisa kay open heart surgery ke liye low temperatures 18 °C, 64 °F tak zarorat hoti hai. Aur doosray specialist procedures jesy neonatal mein high temperatures 28 °C, 82 °F tak zarorat hoti hai.

Integrated circuits ko banane ke liye cleanrooms aur pharmaceuticals waghera jahan par bohat ziyada high level par process ko kamyab karne ke liye saaf hawa aur controlled temperature aur humidity ki zaroorat hoti hai.




Laboratory animals ke liye sahuliyat kyon ki bohat saray animals sirf Spring yani Bahaar mein paida hote hain isliye unhe aisy rooms mein rakha jata hai jahan par Spring jesa he mosam hota hai phir wo sara saal dobara paida ho sakte hain.

Aircraft air conditioning agarcha musafiron ko comfort mein rakhne aur aircraft ke equipment ko cool rakhne ke liye istemal hoti hai par aircraft air conditioning aik khaas process bhi paish karti hai jiski wajah sey aircraft ke bahir low pressure rehta hai.

Dusri examples darj zail cheezain shamil hain:

Plants and Farm Growing Areas
Food Cooking and Processing Areas
Data Processing Centers
Nuclear Facilities
Textile Factories
Mines
Industrial Environments

Comfort aur process applications dono mein maqsad sirf temprature ko control karna nahi hota balkay dsure factors jesy humidity hawa ki harkat aur hawa ki quality ko control karna bhi hota hai.

Air Conditioning System Basics and Theories


Refrigeration Cycle


Refrigeration cycle mein aik pump heat ko lower temperature se higher temperature heat sink mein transfer karta hai. Heat qudrati taur par mukhlif simt mein behti hai ye air conditioning sab sey aam type hai. Aik refrigerated air conditioning system bhi bilkul isi tarah kaam karta hai aur heat ko room sey bahir pump out kar deta hai.

Ye cycle universal gas of law ka faida uthata hai.

PV = nRT, where P is pressure, V is volume, R is the universal gas constant, T is temperature, and nis the number of molecules of gas (1 mole = 6.022×1023 molecules).

Sab sey aam refrigeration cycle compressor ko chalane ke liye electric motor istemal karta hai. Automobile mein compressor engine kay crankshaft par lagi hui pulley sey chalta jata hai dono ke sath air circulation ke liye electric motors ko istemal kiya jata hai. Kyon ki evaporation us waqt hoti hai jab heat jazb ho jati hai aur condensation us waqt hoti hai jab heat release ki jati hai. Air conditioners compressor istemal karne ke liye design kiye jate hain. Ye 2 compartments mein pressure dene ke liye aur enclosed system ke nazdeek coolant pump karte hain. Cooling liquid ya refrigerant ko cooled compartment mein pump kiya jata hai jo evaporator coil hoti hai. Low pressure refrigerant ko heat ke sath evaporate karta hai. Dusre compartment mein condenser refrigerant vapour ko compress kiya jata hai aur isay dusry heat coil ke zariye exchange kiya jata hai ye liquid mein condense karta hai jo phir jazab ki gai heat cool space se reject karta hai.

Health Implications

Air conditioning ka hawa ko thanda karne kay ilawa insani sehat par bhi bohat gehra asar hai. Air conditioning ka allergies aur asthma ke mareezon par positive effect ho sakta hai.
