Then, the control is repeated until “Nal” or “Na2” reaches the cumulative operation number “Nt” (steps S4 to S6), and “Nal” or “Na2” becomes the cumulative operation number “Nt”. When it is reached, the necessity of maintenance is announced (Step S 11), and the accumulated operation count “Nt” is reset (Step S 12) and the process returns to prepare for the next operation.
  • step S2 the control when it is determined that the manual operation is performed in step S2 is the value of the operation number "Nbl" or "Nb2" in step S7.
  • the operation interval for automatic operation i.e., the interval for maintenance notification
  • the interval for maintenance notification for manual operation is set to be the same
  • the number of operations “Nb 1” or the number of operations “Na2” during automatic operation and the number of operations “Nb2” during manual operation are set to be “Nal> Nbl” and “Na2> Nb2”. This is because the cleaning operation is regularly performed every time the maintenance operation is notified in the automatic operation, so the amount of dust per cleaning operation is small.
  • the maintenance operation is not always performed. This is because the cleaning operation is not performed, so the amount of garbage per cleaning operation is considered to be larger than in the automatic operation.
  • the amount of dust accumulated in the dust box 20 is determined, and when the amount reaches a preset maintenance reference amount, the maintenance is performed. In addition to outputting a tenance signal and receiving this maintenance signal, the maintenance of the dust box 20 is notified and the operator performs maintenance. Maintenance of the dust box 20 without making inappropriate judgments due to the frequency of cleaning the filter, unlike the configuration in which the dust box maintenance is informed based on the estimated amount of dust accumulated in the accumulated time. As a result, the air conditioning operation is stopped due to unnecessary maintenance, resulting in a decrease in the comfort of indoor air conditioning or excessive accumulation of dust in the dust box 20.

Abstract

L'invention concerne un appareil de conditionnement d'air permettant de déterminer de manière plus précise et pratique la quantité de poussière collectée dans une boîte à poussière et de notifier le moment approprié pour nettoyer la boîte à poussière. Ledit appareil de conditionnement d'air comprend des moyens de détermination pour déterminer la quantité de poussière collectée dans la boîte à poussière (20) et émettre un signal de nettoyage lorsque la quantité de poussière atteint une quantité seuil prédéterminée pour effectuer un nettoyage, et des moyens de notification pour notifier la nécessité de nettoyer la boîte à poussière (20) à la réception d'un signal de nettoyage provenant des moyens de détermination. Du fait que la construction précitée détermine la quantité de poussière collectée dans la boîte à poussière (20) et fournit une notification de nettoyage en fonction de la détermination, une détermination inappropriée, telle que celle pouvant se produire lorsqu'elle est basée sur la fréquence de nettoyage d'un filtre (13) et sur la quantité de poussière collectée dans le filtre (13) estimée en fonction du temps accumulé pour une opération de conditionnement d'air, ne se produit pas. Dans le dispositif de conditionnement d'air de l'invention, une notification de nettoyage de la boîte à poussière (20) et le nettoyage basé sur cette notification peuvent s'effectuer à un moment plus approprié.
