Supapa de expansiune DPFAA1.0<\/span><\/h2>\n

Descriere<\/strong> Supap\u0103 de expansiune DPF1.0<\/a> este un supap\u0103 cu sec\u021biune de trecere restr\u00e2ns\u0103, destinat\u0103 pentru throttling \u0219i reglarea fluxului de agent frigorific c\u0103tre evaporator \u00een func\u021bie de sarcina termic\u0103. <\/span><\/p>\n

Pentru controlul ERV este necesar un controler, precum \u0219i o surs\u0103 de alimentare pentru motorul pas cu pas al ventilului. Semnalele de intrare ale controlerului sunt citiri ale senzorilor de presiune \u0219i temperatur\u0103 instala\u021bi pe conducta de aspiration. <\/span><\/p>\n

Presiunea de evaporare m\u0103surat\u0103 de senzor corespunde temperaturii de evaporare. Semnalele de temperatur\u0103 indic\u0103 temperatura de super-\u00eenc\u0103lzire a agentului frigorific la ie\u0219irea din evaporator. <\/span><\/p>\n

Controlerul EEV determin\u0103 valoarea de super-\u00eenc\u0103lzire ca diferen\u021ba dintre temperatura de super-\u00eenc\u0103lzire \u0219i temperatura de evaporare. Pentru func\u021bionare corect\u0103 \u0219i sigur\u0103, valoarea super-\u00eenc\u0103lzirii trebuie s\u0103 fie \u00eentre 7\u201310 \u00b0C. <\/span><\/p>\n

Controlerul compar\u0103 valoarea actual\u0103 a super-\u00eenc\u0103lzirii cu valoarea setat\u0103 \u0219i trimite semnalul de control corespunz\u0103tor: pentru deschiderea supapei pentru reducerea super-\u00eenc\u0103lzirii. Supapa de expansiune DPFAA1.0 regleaz\u0103 puterea termic\u0103 de la 2.1 la 4.6 kW (de\u0103inde de agentul frigorific.

Supapa de expansiune DPFAA1.0<\/strong> regleaz\u0103 automat debitul agentului frigorific \u0219i asigur\u0103 func\u021bionarea sistemului \u00een condi\u021bii optime pentru r\u0103cire rapid\u0103 sau \u00eenc\u0103lzire, control precis al temperaturii \u0219i economie de energie. De asemenea, Supapa de expansiune DPFAA1.0<\/strong> poate fi folosit\u0103, de exemplu, pentru controlul presiunii \u00een linia de aspira\u021bie.
