  1. کنترل تطبيقى سيستم‌هاى HVAC مراجع: • Energy simulation of traditional vs. Adaptive thermal comfort for two moderate climate regions J.L.M. Hesen, L. Centnerova • Advanced controller auto-tuning and its application in HVAC systems Qiang Bi, Wen-Jian Cai, Qing-Guo Wang, Chang-Chieh Hang, Eng-Lock Lee, Yong Sun, Ke-Dian Liu, Yong Zhang, Biao Zou • Intelligent Adaptive Control: Intelligent Control of Air Conditioning Systems Jain; Lakhmi C., de Silva; Clarence W.

  2. مقدمه • منظور از HVACچيست؟ • Biotherium چيست؟ • تعريف شرايط راحتى حرارتى • يک سيستم خود تنظيم چيست؟ • منظور از سيستم کنترل تطبيقى هوشمند چيست؟

  3. مطالب مورد بحث • يک سيستم تهويه مطبوع در يک کارخانه توليد نخ مصنوعى • گامى به سوى يک سيستم تهويه مطبوع بينا • يک سيستم تهويه مطبوع در يک clean room

  4. يک سيستم تهويه مطبوع در يک کارخانه توليد نخ مصنوعى با قابليت صرفه‌جويى انرژى Terephthalic acid + Ethylene glycol (Raw material) Polymerization Process Spinning Process Drawing/twisting Process Polyester filament Role of Air conditioning system: • Aging of yarn yet to be drawn • Prevention of yarn from changing physical properties before drawing • Maintaining level of dyeing • Prevention of occurrence of yarn cut and fluff • Purification of room atmosphere [3]

  5. سيستم تهويه مطبوع با کنترل فازى جهت صرفه‌جويى انرژى

  6. قوانين فازى

  7. نتايج

  8. سيستم تهويه مطبوع با قابليت تشخيص موقعيت ساکنان • Distinguish occupants from background in an image using the Fuzzy C-Means algorithm (FCM) • Distinguish each occupant by locating local temperature peaks in the image • Region growing for more accurate segmentation of occupants

  9. يک سيستم کنترل دما و رطوبت فازى با قابليت يادگيرى سيستم کنترل فازى معمول:

  10. Temperature request and humidity request inference • TRV: error of measured and desired temperature together with its deviation • HRV: foreseen error and deviation • Integrated inference If x1 is Ai1, …, x5 is Ai5 then y1 is Bi1, …, y3 is Bi3 x1: last manipulated variable for the cooling valve x2: last manipulated variable for the heating valve X3: last manipulated variable for the humidifying valve X4: temperature request X5: humidity request y1, y2, y3: change in manipulated variable for the cooling. heating and humidifying valve

  15. ب. شرايط راحتى حرارتى “Condition of mind, which expresses satisfaction with the thermal environment.” [1] Criteria’s for thermal comfort (PMV index): • Air temperature • Radiant temperature • Humidity • Air velocity • Personal parameters such as clothing and metabolic rate Criteria’s for thermal discomfort: • Draught • High vertical temperature difference between head and ankles • Too high radiant temperature asymmetry “The optimum operative temperature for comfort is a function of metabolic rate and clothing insulation.” [1] Return to Introduction
