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. 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. 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. 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 <strong>DPFAA2.4<\/strong> regulates the thermal power from 13.0 to 28.8 kW (depending on the refrigerant). <strong>For consultations, contact +37369104125.<\/strong> <strong>Expansion valve DPFAA2.4 <\/strong>is intended for use in systems <a href=\"https:\/\/altal.ro\/en\/heat-pump-altal\/\">reversible heat pumps<\/a>. Expansion valve <strong>DPFAA2.4<\/strong>\u00a0automatically regulates the refrigerant flow and ensures the system operates in optimal conditions for rapid cooling or heating, precise temperature control and energy saving.
