Abnormal state detecting apparatus of multi-type air conditioner and method thereof

Abstract

The invention discloses an abnormal state detection device and method for a compound air conditioner. The method includes: a user selects a test run, and then detects a plurality of indoor temperatures of an indoor area where a plurality of indoor units are installed and a plurality of outdoor temperatures of an outdoor area where a plurality of outdoor units are installed; The average indoor temperature and the average outdoor temperature of multiple detected outdoor temperatures, select a corresponding test operation mode in multiple preset test operation modes; test and run the duplex air conditioner according to the selected test operation mode, and collect and display the test The data of the running state of the running air conditioner; and comparing the collected data with the preset reference data, and judging the abnormal state of the air conditioner based on the comparison result.

Description

technical field [0001] The invention relates to a compound air conditioner, and in particular to an abnormal state detection device and method for the compound air conditioner. Background technique [0002] Generally, an air conditioner is a device used to control temperature, humidity, airflow, and cleanliness of indoor air to achieve a comfortable indoor environment. According to the structure of the unit, air conditioners are roughly divided into one-piece air conditioners, that is, indoor units and outdoor units are installed in one cabinet; and split-type air conditioners, that is, the compressor and condenser are built as an outdoor unit, and the evaporator is built as indoor unit. [0003] The split type air conditioner includes a cooling / heating air conditioner that selectively performs a cooling operation and a heating operation of the air conditioner by switching a flow path of refrigerant using a flow path switching valve. [0004] Recently, a multi-type air con...

Problems solved by technology

[0016] However, when installing multiple indoor units and multiple outdoor units of a multi-type air conditioner, installation failures such as defective pipe connections, wrong connections of communication lines, etc., or mechanical damage may occur

[0017] That is, in the traditional multi-type air conditioner, due to the complex structure of the air conditioner, it is impossible to accurately detect abnormal conditions, such as unqualified installation or mechanical damage of the air conditioner, thereby reducing the function of the air conditioner or causing mechanical damage to the air conditioner
