Description
Avente per titolo: “Dispositivo di attivazione della resistenza PTC presente nella vaschetta raccogli condensa” in seguito denominato “DRP” Entitled: "Device for activating the PTC resistance in the condensate collection tray" hereinafter referred to as "DRP"
STATO DELL’ARTE: STATE OF THE ART:
Gli impianti frigoriferi hanno la necessità di raccogliere e smaltire acqua ottenuta durante i normale funzionamento, solitamente l’acqua viene raccolta in una bacinella o vaschetta e successivamente viene espulsa dal impianto. Uno dei sistemi adottati per eliminare l’acqua raccolta è quello di riscaldarla con una resistenza elettrica in modo da ottenerne l’evaporazione. Il sistema è sicuramente pratico, in quanto non necessità di allacciamenti alla rete di scarico, ma richiede un consumo continuo di energia elettrica anche dopo che l’acqua presente nella vaschetta è completamente evaporata. Le resistenze elettriche utilizzate a tale scopo sono definite resistenze PTC, la loro resistenza varia al variare della temperatura, la potenza assorbita ha il suo massimo quando la resistenza è completamente immersa ne liquido e il suo minimo quando è completamente fuori dal liquido. È chiaro che una volta evaporata l’acqua presente nella vaschetta, la resistenza PTC continuerà ad assorbire energia anche se in quantità minore, fino al successivo riempimento della vaschetta. La condizione ideale si ottiene se al termine dell’evaporazione la resistenza viene staccata dalla rete elettrica il dispositivo deve quindi essere in grado di percepire il passaggio da una condizione di massimo consumo elettrico ad una di minimo consumo elettrico e interrompere l’assorbimento elettrico della resistenza PTC. Refrigeration systems need to collect and dispose of water obtained during normal operation, usually the water is collected in a basin or tray and is subsequently expelled from the system. One of the systems adopted to eliminate the collected water is to heat it with an electric resistance in order to obtain evaporation. The system is certainly practical, as it does not need to be connected to the drainage network, but requires a continuous consumption of electricity even after the water in the tray has completely evaporated. The electrical resistances used for this purpose are defined as PTC resistors, their resistance varies with temperature variations, the absorbed power has its maximum when the resistance is completely immersed in the liquid and its minimum when it is completely out of the liquid. It is clear that once the water in the tray has evaporated, the PTC resistance will continue to absorb energy, albeit to a lesser extent, until the tray is subsequently filled. The ideal condition is obtained if, at the end of evaporation, the resistance is disconnected from the electrical network, the device must therefore be able to perceive the passage from a condition of maximum electrical consumption to one of minimum electrical consumption and interrupt the electrical absorption of the resistance. PTC.

DISPOSITIVO DI ATTIVAZIONE DELLA RESISTENZA PTC “DRP” (8) Rilevazione della condizione di minimo assorbimento: Tale condizione si presenta quando il consenso alimentazione resistenza PTC (4) è attivo e la tensione ai capi del rilevatore (5) dopo essere stata amplificata (6) risulta essere minore del limite stabilito con il comparatore (7). DEVICE FOR ACTIVATING THE PTC RESISTANCE "DRP" (8) Detection of the condition of minimum absorption: This condition occurs when the PTC resistor power consent (4) is active and the voltage across the detector (5) after being amplified (6 ) turns out to be less than the limit established with the comparator (7).
ESEMPLIFICAZIONE CASO TIPICO: TYPICAL CASE EXEMPLIFICATION:
A titolo esemplificativo ma non esclusivo si riporta di seguito un utilizzo del dispositivo di attivazione della resistenza PTC “DRP”. Al dispositivo “DRP” viene collegata la resistenza PTC, collocata nella bacinella raccogli condensa, il segnale di sbrinamento attivo e Talimentazione elettrica. Al termine dell’attività di sbrinamento, viene mantenuto attivo il consenso alimentazione alla resistenza PTC. II consenso perdura fino al rilevamento della condizione di minimo assorbimento, questa condizione coincide con l’evaporazione del liquido raccolto nella bacinella. By way of example but not exclusively, the following is a use of the PTC resistor activation device "DRP". The PTC resistor, located in the condensate drain pan, the active defrost signal and the power supply are connected to the “DRP” device. At the end of the defrosting activity, the power supply consent to the PTC resistance is kept active. The consent lasts until the minimum absorption condition is detected, this condition coincides with the evaporation of the liquid collected in the basin.
