WebLe concept qui sous-tend les condenseurs est le transfert de chaleur. Il s’agit du principe thermodynamique décrivant comment la chaleur se déplace toujours d’un environnement plus chaud vers un environnement plus froid. Trois phases différentes se produisent dans un condenseur. La première phase est appelée désurchauffe.
WebThe way refrigeration works is by moving heat from a place with a low temperature to a place with a higher temperature. This is done by going through a cycle of compression, heating, and expansion, all of which change the form of thermal energy. First, a compressor is used to squeeze the refrigerant, which raises its temperature and pressure. mapleview cibchttp://plus.hoshizakiamerica.com/techtips/Pdf/All/Tips206.pdf krishna art wallpaperWebJan 6, 2014 · Any refrigeration system’s receiver should be able to hold all of the system’s refrigerant charge and still have a 25 percent vapor head for safety.
