La v\u00e0lvula inversora de 4 vies \u00e9s un component cr\u00edtic del circuit de refrigerant: redirigeix el flux de refrigerant a trav\u00e9s del sistema, permetent que la bomba de calor canvi\u00ef entre els modes de calefacci\u00f3 i refrigeraci\u00f3. Una v\u00e0lvula defectuosa o avariada impedir\u00e0 que la unitat canvi\u00ef de mode o mantingui la temperatura correcta de l'aigua de la piscina.<\/p>\n<h3>Com funciona<\/h3>\n<p>A l'interior de la v\u00e0lvula, un carret lliscant accionat per solenoide connecta quatre ports de refrigerant en dues configuracions diferents. En mode calefacci\u00f3, la v\u00e0lvula dirigeix el refrigerant calent cap a l'intercanviador de calor d'aigua; en canviar d'estat s'inverteix el cicle per al refredament o per a un funcionament eficient de desgla\u00e7. El solenoide s'activa mitjan\u00e7ant un senyal de la placa de control de la bomba de calor, fet que converteix la v\u00e0lvula en un element central per a un funcionament fiable durant tot l'any del PM40 MD5.<\/p>\n<h3>Compatibilitat<\/h3>\n<p>Aquesta v\u00e0lvula est\u00e0 dissenyada exclusivament per a la Bomba de Calor AstralPool PM40 MD5, identificada amb l'SKU principal WH000422. Verifica sempre el model i el n\u00famero de s\u00e8rie de la teva unitat amb el diagrama de despiece oficial de Fluidra (posici\u00f3 30) abans de fer la comanda. No es confirma que aquesta v\u00e0lvula sigui compatible amb cap altre model de bomba de calor AstralPool.<\/p>\n<h3>Per qu\u00e8 l'autenticitat importa<\/h3>\n<p>Utilitzar una v\u00e0lvula de recanvi original AstralPool garanteix la mida correcta dels ports, la compatibilitat del refrigerant i l'especificaci\u00f3 adequada del solenoide per al circuit de refrigeraci\u00f3 del PM40 MD5. Les alternatives no originals poden provocar fuites de refrigerant, desequilibris de pressi\u00f3 o avaries a la placa de control que comprometen tant l'efici\u00e8ncia com la garantia. Substituir-la per la pe\u00e7a original mant\u00e9 la bomba de calor funcionant d'acord amb les seves especificacions nominals.<\/p>","protected":false},"excerpt":{"rendered":"<p>AstralPool &#8211; 4-Way Reversing Valve for Heat Pump PM40 MD5 This is the genuine AstralPool OEM 4-way reversing valve (position 30 in the official Fluidra exploded view) designed specifically for the AstralPool Heat Pump PM40 MD5 (WH000422).
