Dac\u0103 aerul condi\u021bionat porne\u0219te dar nu mai bag\u0103 frig<\/strong> \u0219i:
\n– ieri c\u00e2nd l-ai oprit f\u0103cea rece iar azi doar v\u00e2ntur\u0103 aerul din camer\u0103
\n– ventilatorul cel mare din unitatea de afar\u0103 se \u00eenv\u00e2rte
\n– cele dou\u0103 \u021bevi de freon sunt calde. (cea sub\u021bire ar trebui s\u0103 fie mai rece sau chiar cu ghea\u021b\u0103)
\n\"\"<\/a><\/p>\n

– Este model vechi-clasic – f\u0103r\u0103 inverter. Dac\u0103 e inverter, Urm\u0103torul, v\u0103 rog!<\/strong>
\nNu e panic\u0103. Se rezolv\u0103 u\u0219or. Nu a f\u00e2s\u00e2it tot freonul de ieri p\u00e2n\u0103 azi.
\nNu mai porne\u0219te compresorul.<\/strong> <\/em><\/span>E de la condensatorul de pornire, ca la frigiderul p\u0103rin\u021bilor.
\nO ureche fin\u0103 poate chiar auzi un sunet, un b\u00e2z\u00e2it, ca un motor blocat, urmat de un CLIK! Apoi pauz\u0103, apoi totul se repet\u0103.<\/p>\n

Motorul blocat e compresorul, iar CLIK!-ul e protec\u021bia lui termic\u0103, ce decupleaz\u0103 alimentarea c\u00e2nd compresorul se \u00eencinge. Ca s\u0103 nu se ard\u0103.<\/p>\n

Mic\u0103 introducere teoretic\u0103:<\/strong>
\nCompresorul, fiind destul de puternic, e construit\/bobinat ca un motor trifazat. (ca \u0219i motorul de hidrofor, polizor…) El nu poate porni cu tensiune monofazat\u0103 (de la priz\u0103) \u0219i de aceea, pentru a simula tensiunea trifazat\u0103 (cu cele 3 faze decalate la 120\u00b0), se introduce un condensator \u00een serie cu una dintre \u00eenf\u0103\u0219ur\u0103ri, care introduce un defazaj \u0219i apare c\u00e2mpul magnetic rotativ \u0219i motorul \u00eencepe s\u0103 se \u00eenv\u00e2rt\u0103\u00a0 \ud83d\ude09 .
\nF\u0103r\u0103 acest condensator nu exist\u0103 defazaj \u00eentre \u00eenf\u0103\u0219ur\u0103ri\/c\u00e2mp magnetic \u0219i motorul nu se \u00eenv\u00e2rte, doar se \u00eencinge p\u00e2n\u0103 se arde\u00a0\ud83d\ude2f .
\nS\u0103 nu mai vorbim de faptul c\u0103 motorul de compresor de instala\u021bie frigorific\u0103 porne\u0219te cu sarcina maxim\u0103 pe el, deci trebuie s\u0103 trag\u0103 tare.
\nAici intervine avantajul tehnologiei inverter… dar asta \u00eentr-un alt episod.<\/p>\n

Deci, condensatorul.<\/strong>
\n1. Desf\u0103cut carcasa unit\u0103\u021bii exterioare (multe \u0219uruburi)

Spray-ul pentru viespi este acolo pentru… viespi\u00a0 \ud83d\ude42
\n2. Inspectat condensatorul pentru a vedea valoarea

S\u0103 vezi surpriz\u0103! E un condensator dublu (dou\u0103 condensatoare \u00een aceea\u0219i carcas\u0103), unu pentru compresor, de 35\u03bcF \u0219i unu pentru ventilator, de 1,5\u03bcF. Sigur, dac\u0103 cel pentru compresor e compromis, \u00eenseamn\u0103 c\u0103 \u0219i cel pentru ventilator este. Dar de ce totu\u0219i ventilatorul se \u00eenv\u00e2rte?! Pentru c\u0103 are sarcin\u0103 foarte mic\u0103 \u0219i o sc\u0103dere a valorii condensatorului nu \u00eel afecteaz\u0103 a\u0219a tare. Trebuie doar s\u0103 \u00eenving\u0103 rezisten\u021ba aerului. U\u0219or.
\nDar care e treaba cu SLAD OIL\u00a0 \ud83d\ude00 \ud83d\ude00 ?!<\/p>\n

Am g\u0103sit \u0219i o schem\u0103 electric\u0103
\n\"\"<\/a>
\nSe vede \u0219i aici cum cele dou\u0103 motoare sunt trifazate.<\/p>\n

3. Noul condensator.
\nAm c\u0103utat condensator nou, la fel, dar nu am g\u0103sit \u00een marile magazine. Pentru on-line trebuia s\u0103 transpir o s\u0103pt\u0103m\u00e2n\u0103.
\nAm luat unul normal (nu dublu) de\u00a035\u03bcF, de la Leroy Merlin, 20 de lei.
\n\"\"<\/a><\/p>\n

Acesta are un cablu \u0219i i-am pus papuci pentru montarea \u00een circuit f\u0103r\u0103 modific\u0103ri.
\n\"\"<\/a><\/p>\n

Spa\u021biul e foarte generos \u0219i se monteaz\u0103 f\u0103r\u0103 probleme.
\n\"\"<\/a><\/p>\n

Pentru probe…
