Un refrigeratore comprende principalmente compressore, condensatore, dispositivo di espansione ed evaporatore.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Compressore<\/strong> \u00e8 il componente principale dell'unit\u00e0 di refrigerazione, il gas freon utilizzato come refrigerante. Il compressore viene utilizzato per pompare il gas freon attraverso il circuito e comprimere il gas freon ad alta pressione e temperatura. Condizioni del refrigerante all'uscita del compressore: alta pressione e alta temperatura.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Condensatore<\/strong> riduce la temperatura del refrigerante (gas freon) da una temperatura elevata a una bassa temperatura con una pressione desiderata. Il condensatore pu\u00f2 essere raffreddato ad aria o ad acqua. Condizioni del refrigerante all'uscita del condensatore: alta pressione e bassa temperatura.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Dispositivo di espansione<\/strong> \u00e8 chiamata anche valvola a farfalla che riduce la pressione del refrigerante (gas freon) da alta a bassa pressione passando attraverso uno spazio ristretto, riducendo cos\u00ec ulteriormente la temperatura del refrigerante (gas freon). Il dispositivo di strozzatura normalmente utilizzato \u00e8 costituito da tubi capillari, come mostrato nell'immagine. Condizioni del refrigerante all'uscita della valvola a farfalla: bassa pressione e temperatura di registro <strong>Evaporatore<\/strong> \u00e8 il luogo in cui avviene l'effettivo scambio di calore. Il refrigerante dalla valvola a farfalla raggiunge l'evaporatore e raffredda l'acqua. Condizioni del refrigerante all'uscita dell'evaporatore: pressione e temperatura normali.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"554\" height=\"390\" src=\"http:\/\/gwsionline.com\/wp-content\/uploads\/2020\/08\/image.png\" alt=\"\" class=\"wp-image-400\"\/><\/figure>","protected":false},"excerpt":{"rendered":"<p>A Chiller is a machine which is used to reduce the temperature of the medium ( water ) or cooling the water by vapour compression or vapour absorption system.
