\n\tLes refroidisseurs industriels \u00e0 condensation par air sont g\u00e9n\u00e9ralement des machines int\u00e9grales, c'est-\u00e0-dire que l'\u00e9vaporateur, le compresseur et le condenseur sont fabriqu\u00e9s ensemble. Pour un refroidisseur industriel \u00e0 refroidissement par air de puissance l\u00e9g\u00e8rement \u00e9lev\u00e9e, la dissipation de chaleur du ventilateur de refroidissement du condenseur doit \u00eatre prise en compte. Comme la source d'\u00e9change de chaleur du refroidisseur \u00e0 air est l'air et qu'il est \u00e9quip\u00e9 d'un ventilateur sp\u00e9cial, il est appel\u00e9 \"refroidisseur \u00e0 air\". Il est largement utilis\u00e9 dans les secteurs de la m\u00e9decine, de la biologie, de la chimie, du laser, de la m\u00e9tallurgie, de la fabrication d'\u00e9quipements, de la galvanoplastie, de la transformation des mati\u00e8res plastiques et d'autres industries.

\n\tWorking principle of air-cooled industrial chiller: different from the traditional water-cooled chiller, the air-cooled chiller does not need the cooling capacity brought by the cooling tower, so it avoids more investment, and is easy to install and manage. Casters are equipped at the bottom of the chiller, which can be moved to cycle between different working areas. This saves a lot of unnecessary fixed investment, and cold water can be discharged directly by connecting power supply and water pipe. According to the design requirements, the outlet water temperature is generally 2 <\/span>\u2103<\/span>, 0 <\/span>\u2103<\/span>, -5 <\/span>\u2103<\/span> and -15 <\/span>\u2103<\/span>. When the temperature is below zero, the refrigerant needs to be mixed for heat exchange. The commonly used refrigerant is ethylene glycol.<\/span>\n<\/p>\n

\n\tComme le refroidisseur conventionnel, le refroidisseur \u00e0 condensation par air a \u00e9galement un cycle de r\u00e9frig\u00e9ration fixe. Le principe consiste \u00e0 utiliser l'effet Carnot inverse, qui est similaire \u00e0 celui des climatiseurs domestiques actuels, mais la structure du syst\u00e8me de la boucle de r\u00e9frig\u00e9ration est am\u00e9lior\u00e9e, de sorte que le coefficient d'efficacit\u00e9 \u00e9nerg\u00e9tique est souvent tr\u00e8s \u00e9lev\u00e9.<\/span>\n<\/p>\n

\n\tCharacteristics of air-cooled industrial chiller:<\/span>\n<\/p>\n

\n\t1. Toutes les tuyauteries sont isol\u00e9es thermiquement afin d'\u00e9viter la convection locale des tuyauteries de la machine.<\/span>\n<\/p>\n

\n\t2. Cooling temperature range: 5 <\/span>\u2103<\/span> ~ 35 <\/span>\u2103<\/span>.<\/span>\n<\/p>\n

\n\t3. Le r\u00e9gulateur de temp\u00e9rature ind\u00e9pendant est dot\u00e9 d'une protection antigel.<\/span>\n<\/p>\n

\n\t4. R\u00e9servoir d'eau isol\u00e9 en acier inoxydable.<\/span>\n<\/p>\n

\n\t5. Protection de la s\u00e9quence des phases de la ligne de contr\u00f4le et contr\u00f4le des interrupteurs haute et basse tension du syst\u00e8me de r\u00e9frig\u00e9ration.<\/span>\n<\/p>\n

\n\t6. Le condenseur \u00e0 ailettes optiques hydrophiles a un meilleur effet de transfert de chaleur et une dissipation thermique plus rapide.<\/span>\n<\/p>\n

\n\t7. Le compresseur et la pompe sont dot\u00e9s d'une protection contre les surcharges.<\/span>\n<\/p>\n

\n\t8. L'\u00e9vaporateur \u00e0 coquille et \u00e0 tube de grande capacit\u00e9 est adopt\u00e9, ce qui a un bon effet de r\u00e9frig\u00e9ration et peut \u00eatre appliqu\u00e9 \u00e0 l'environnement \u00e0 haute temp\u00e9rature.<\/span>\n<\/p>\n

\n\t9. Le r\u00e9frig\u00e9rant utilis\u00e9 est le R404A, qui a un bon effet de r\u00e9frig\u00e9ration.<\/span>\n<\/p>\n

\n\t10. Le r\u00e9frig\u00e9rant \u00e9cologique R507C est en option.<\/span><\/p>","protected":false},"excerpt":{"rendered":"

Industrial air-cooled chillers are generally integral machines, that is, evaporator, compressor and condenser are made together. For a slightly high-power air-cooled industrial chiller, the heat dissipation of the condenser cooling fan needs to be considered. Since the heat exchange source of air-cooled chiller is air and equipped with special fan, it is called “air-cooled chiller”.
