Heat exchange unit troubleshooting method and system

Abstract

The invention discloses a heat exchange unit troubleshooting method and system. The heat exchange unit troubleshooting method comprises the following steps that the trouble type of a heat exchange unit is judged by a master controller; relevant parameters corresponding to the trouble type are selected and exported by the master controller from operation parameters which are obtained by a detection device; and a failed part of the heat exchange unit is judged according to the relevant parameters and troubleshooting is conducted. When a trouble happens to the heat exchange unit, the trouble type of the heat exchange unit is firstly judged by the master controller; then the relevant parameters corresponding to the trouble type are selected from the operation parameters by the master controller; and finally a state of the relevant parameters is examined and the relevant parameters are analyzed, so that the failed part of the heat exchange unit is determined, a corresponding solution to the discovered trouble is found, and troubleshooting is achieved. According to the heat exchange unit troubleshooting method, the trouble can be found rapidly and efficiently according to the relevant parameters corresponding to the trouble type, so that the troubleshooting time is shortened and the maintenance efficiency is improved.

Description

Technical field [0001] The invention relates to the field of troubleshooting for heat exchange units, and in particular to a method and system for troubleshooting for heat exchange units. Background technique [0002] Heat exchange units (such as air conditioning units or heat pump units) have the advantages of high degree of automation and good energy saving, and are widely used in residences, institutions, hospitals, schools and other occasions. With the development of society and the advancement of science and technology, the structure of heat exchange units has become more and more complex, and the possibility of failures has greatly increased. When the traditional heat exchange unit fails, the main controller of the heat exchange unit will report the failure. The maintenance personnel need to find or detect the root cause of the failure of the heat exchange unit according to the failure reported by the main controller. However, there may be many factors causing the failure. ...

AI Technical Summary

Problems solved by technology

When the traditional heat exchange unit fails, the main controller of the heat exchange unit will report the failure, and the maintenance personnel need to find or detect the root cause of the failure of the heat exchange unit in turn according to the failure reported by the main controller, but there may be many factors causing the failure This one-by-one inspection not only increases the inspection time and reduces the maintenance efficiency, but also easily misses the inspection, and cannot completely eradicate the fault.
