High-pressure sensor fault handling method and device

Abstract

The invention provides a high-pressure sensor fault handling method and device and relates to the technical field of air conditioners. The method and device are characterized in that outdoor ambient temperatures of a first temperature adjusting module under normal running, first measured high pressures and incoming tube and outgoing tube temperatures of a condenser are acquired, first and second proportional coefficients are calculated based on the multiple groups of outdoor ambient temperatures, first measured high pressures, and incoming tube and outgoing tube temperatures of the condenser,virtual high pressures are calculated based on the first and second proportional coefficients, a preset formula and current incoming tube and outgoing tube temperatures if a high-pressure sensor fails, the virtual high pressures are used to replace the first measured high pressures so that breakdown of a temperature adjusting system is never caused at the premise of maintaining the first temperature adjusting module to normally run; therefore, the stability of the temperature adjusting system is improved, and customer experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a high-voltage sensor fault handling method and device. Background technique [0002] With the continuous development of society and the continuous innovation of science and technology, more and more building management systems adopt a unified temperature adjustment method to achieve the purpose of convenient management and energy saving. Existing temperature adjustment systems mainly include modular multi-connectors or air / water-cooled modular machines, etc. Modular multi-connected or air / water-cooled modular machines can form a huge network to act as air conditioners for large buildings and achieve temperature for large buildings. Adjustment function. [0003] Although the existing multi-line or air / water-cooled module units have the characteristics of energy saving and mutual backup, in the current control mode, once the high-voltage sensor of any module fails, a fau...

Problems solved by technology

[0003] Although the existing multi-line or air / water-cooled module units have the characteristics of energy saving and mutual backup, in the current control mode, once the high-voltage sensor of any module fails, a fault code will be prompted, causing the entire network to fail. All other units in the building are shut down and can only wait for maintenance personnel to come to repair, which will cause the temperature regulation system in the building to be in a state of paralysis in a short period of time, reducing the experience of customers
