Olen ymmärtänyt että kaikki ILP:it toimivat suurin piirtein noin. Teksti sinänsä ei kerro että millaiset ne raja-arvot ovat ja mistä suunnasta niitä lähestytään.
Tuo kuva näyttää minusta siltä että on kyllä sulattanut, mutta se on jäänyt kesken. Ilmeisesti tässäkin on aikakatkaisu tietyn sulatusajan jälkeen, vaikka tarvittavaa loppulämpöä ei saavuteta. Ei taida olla ainoa kone jossa sulatusenergia ei riitä pienimmällä ylläpidolla pakkaskeliin.
Onko tuo pistotulppaliitännällä?

Will NOT defrostSamaa ihmetelly omasta vanhasta on/off koneesta, kun teki aamulla 32 asteista ilmaa vaikka ulkona -15.
Onkohan tuota tutkittu mitenkään, että paljonko coppiin vaikuttaa imuilman lämpötila? Onko coppi parempi autotallin kuin asuinhuoneen imuilmasta. Siirtyykö lämmin tehokkaammin viileämpään ilmaan? En tiedä, kunhan pohdin. Eräs vanha kylmäalan ammattilainen sanoi mulle auton ilmastoinnin täytön yhteydessä kerran, että moni huudattaa täysillä auton ilmastointia, kun pienemmällä puhalluksella ilma ehtisi paremmin jäähtyä ja tulisi kylmempää ilmaa suuttimista. Pitäneekö paikkansa?
Tietenkin on. Teoreettinen maksimi riippuu lähinnä lämpötilaerosta eli karkeasti -18 C ulkoilmasta on vain 26 astetta +8 C talliin. Vastaa siis suunnilleen -6 C 20 C sisälämmöllä.
