Definitions

  • the present invention provides an air-conditioning system
  • the air-conditioning system includes: Main working branch, reserve branch, indoor heat exchanger and control unit; the main working branch and reserve branch are arranged in parallel, and the outlets of the main working branch and reserve branch are connected to the indoor heat exchanger
  • the reserve branch includes: a control valve and a detachable liquid storage tank, the liquid storage tank is used to contain high-pressure liquid gas, and the control valve is used to connect the liquid storage tank with the indoor heat exchanger or disconnected; the control unit is used to trigger the control valve of the reserve branch to connect the liquid storage tank with the indoor heat exchanger when the electricity consumption peak is currently in use, so that the liquid storage tank is The indoor heat exchanger provides high pressure liquid gas for refrigeration.
  • the number of reserve branches 30 can be set according to actual conditions. For example, when the area refrigerated by the air-conditioning system is relatively large, a relatively large number of reserve branches 30 can be provided; when the area refrigerated by the air-conditioning system is relatively small, a relatively small number of reserve branches 30 can be provided. . For another example, in areas with relatively high temperature, there is a stronger demand for cooling, and a relatively large number of reserve branches 30 can be provided; in other areas, a relatively small number of reserve branches 30 can be provided.
  • the air conditioning system also includes a mounting seat 32, which is used to install the liquid storage tank 31 to the installation position, and the installation position of the liquid storage tank 31 can be set according to actual needs.
  • the installation position of the liquid storage tank 31 is not specifically limited here.
  • the mounting base 32 may have a docking port, the liquid storage tank 31 has a docking end, and the docking end is pluggably inserted into the docking port.
  • the mounting seat 32 may specifically include a mounting substrate, and one side of the mounting substrate is used to be fixed at the mounting position.
  • the pressure sensor of the liquid storage tank 31-3 of the leftmost reserve branch 30 is located in real time or every interval Detect the actual pressure value of the liquid storage tank 31-3 within a preset time period, and when the control unit 70 determines that the actual pressure value of the liquid storage tank 31-3 drops to the lower pressure limit value according to the detection result of the pressure sensor, it indicates that the storage tank 31-3 is After the high-pressure liquid gas in the liquid tank 31-3 is released, the control unit 70 triggers the closing of the first electric cut-off valve 33-3 of the reserve branch 30, and the high-pressure liquid gas in each reserve branch 30 is released.

Abstract

La présente invention se rapporte au domaine technique des systèmes de conditionnement d'air et concerne spécifiquement un système de conditionnement d'air, et vise à résoudre le problème de l'utilisation d'un système de conditionnement d'air existant qui est limitée en raison d'une grande consommation d'énergie pendant le fonctionnement normal du système de conditionnement d'air. Le système de conditionnement d'air de la présente invention comprend : une branche de travail principale, une branche de réserve, un échangeur de chaleur intérieur et une unité de commande ; la branche de travail principale et la branche de réserve sont agencées en parallèle, et des sorties de la branche de travail principale et de la branche de réserve sont reliées à l'échangeur de chaleur intérieur ; la branche de réserve comprend une soupape de commande et un réservoir de stockage de liquide agencé de manière détachable, le réservoir de stockage de liquide étant utilisé pour contenir du gaz liquide à haute pression, et la soupape de commande étant utilisée pour relier ou désaccoupler le réservoir de stockage de liquide et l'échangeur de chaleur intérieur ; l'unité de commande est utilisée pour déclencher la soupape de commande de la branche de réserve afin de relier le réservoir de stockage de liquide et l'échangeur de chaleur intérieur lorsqu'on se trouve actuellement dans une période de pointe de consommation d'énergie, de telle sorte que le réservoir de stockage de liquide fournit du gaz liquide à haute pression pour l'échangeur de chaleur intérieur afin de mettre en œuvre la réfrigération.
