As discussed herein, a first aspect of the present invention provides a method of providing improved efficiency in heating/cooling. The method can include operating an HVAC system that includes first and second heat pump compressors working together with corresponding heat pump expansion valves and heat pump heat exchangers. The method can include collecting HVAC fluid information concerning actual conditions of an HVAC fluid flowing in the HVAC system via sensors positioned in various places throughout the HVAC system. The method can include transmitting an update that includes HVAC fluid information. The method can include receiving control instructions at a heat pump controller. The method can include implementing the control instructions with the heat pump controller. Steps of the method can be repeated periodically during operation of the HVAC system.

L'invention concerne, selon un premier aspect, un procédé améliorant l'efficacité du chaufffage/conditionnement d'air, qui peut consister à exploiter un système de chauffage, ventilation, conditionnement d'air (CVC) doté de premier et second compresseurs de pompe à chaleur agissant ensemble, avec des détendeurs et des échangeurs thermiques de pompe à chaleur correspondants. Le procédé peut consister à collecter une information de fluide CVC sur les conditions effectives d'un fluide CVC s'écoulant dans le système CVC via des capteurs placés en divers points du système. Le procédé peut consister à transmettre une mise à jour qui contient une information de fluide CVC et aussi à recevoir des instructions de commande au niveau d'un contrôleur de pompe à chaleur. Enfin, il peut consister à mettre en oeuvre les instructions de commande par le biais de ce contrôleur. On peut répéter les étapes du procédés de façon périodique durant l'exploitation du système.
