برنامج لإختيار طول وقطر المواسير الشعرية [Capillary Tube Selection]
بسم الله الرحمن الرحيم
 مرحباً بكم فى  هو برنامج تابع لشركـــــــة دانفوس  هذا البرنامج لحساب طول وقطر المواسير الشعرية برنامج لإختيار المواسير الشعرية [Capillary Tube Selection]  شرح مبسط للبرنامج  لضبط الوحدات بالبرنامج حسب النظام الذى تعمل عليه   Introduction لم يتبقى إلا تحميل البرنامجThis software allows the user to calculate a capillary tube throttling device for a refrigeration system based on empirical formulas. The result is a start value for optimization, this start value typically giving a functioning system. In certain cases the best possible choice of capillary diameter and length might deviate remarkably from this calculated result. The capillary sizing is based on the assumption, that - the suction line is connected to the capillary tube in most of its length for internal heat exchange - no or little subcooling appears in continuous operation The refrigerant used is to be chosen from a list. Input values should be representative dimensioning values for the refrigeration system. The input value for - capacity is to be taken for the also to be input operating conditions, in terms of - evaporating temperature - condensing temperature - return gas temperature and- without subcooling for the compressor type used, preferably. The input data are limited per refrigerant according to experience and compressor application areas. Data like these could be according to data sheet performance data at ARI 540, EN 12900 or CECOMAF conditions, or taken from a software selection tool like Danfoss RS™. The list of capillary tube inner diameters does contain typically available sizes from different countries. They will not all be available at one place. A length value for an available diameter size is to be chosen by the user, or guessed, if not listed. The list of refrigerants and capillary tube diameters and the calculation formulas and limits might be altered at updates, based on new experience  System requirements- Min. 200 MHz Pentium® or compatible 32 MB RAM min., 64 MB recommended 15 MB harddisk space Microsoft Windows 95®, 98, ME, XP, NT 4.0, 2000 or newer   هذا وبالله التوفيق والحمد لله رب العالمين لاتنسونى من صالح دعائكم |
