Variable frequency air conditioner indoor unit, variable frequency air conditioner outdoor unit, variable frequency air conditioner system and outdoor unit parameter remote upgrading method

Abstract

The invention relates to an air conditioner outdoor unit parameter upgrading technology, and discloses a variable-frequency air conditioner indoor unit, a variable-frequency air conditioner outdoor unit, a variable-frequency air conditioner indoor unit system and a variable-frequency air conditioner outdoor unit parameter remote upgrading method. Existing hardware and existing communication speedare utilized, variable-frequency air conditioner outdoor unit parameter remote upgrading is achieved by modifying software, and therefore the problems existing when maintenance personnel detach the outdoor unit from home to replace a mainboard or refresh the software are solved. According to the method, the outdoor unit control parameters are separated from the outdoor unit control program, and when the outdoor unit runs, the control program calls the required control parameters from the data flash. An upgrading instruction is added in a communication protocol of an indoor unit and an outdoorunit, when parameters of the outdoor unit need to be upgraded, a server firstly upgrades the indoor unit through WiFi to enable indoor unit software to contain new control parameters of the outdoor unit, and then the indoor unit sends the new control parameters of the outdoor unit to the outdoor unit through the communication protocol. The method is suitable for remotely upgrading the air conditioner outdoor unit of the user in various environments.

Description

technical field [0001] The invention relates to a technology for upgrading the parameters of an external unit of an air conditioner, in particular to a method for remotely upgrading the parameters of an inverter air conditioner, an internal unit, an external unit, a system and an external unit. Background technique [0002] When the outdoor unit of the inverter air conditioner leaves the factory, various control parameters of the air conditioner will be uniformly set, for example: [0003] 1) Frequency hopping points set to avoid certain resonance frequency points during compressor operation; [0004] 2) The exhaust temperature protection value set to prevent the compressor exhaust temperature from being too high; [0005] 3) The current protection value set to prevent the abnormal current of the outdoor unit, etc. [0006] The above parameters are measured under laboratory conditions and are valid for most users. However, depending on the installation and usage environme...
