System and method for detecting multi-split air conditioner

Abstract

The invention provides a system and a method for detection a multi-split air conditioner. The multi-split air conditioner detection system comprises: first medium tube thermal bulbs (31), which are arranged on evaporator elbows (13) of a first air-conditioner indoor unit (11) and is used for sensing temperatures of the first medium tube at the evaporator elbows (13) of the first air-conditioner indoor unit (11); and a processor (33), which is used for obtaining the first medium tube temperatures when the first air-conditioner indoor unit (11) is in a working state, comparing the obtained first medium tube temperatures with a first preset temperature, and determining whether there is a fault at the first air-conditioner indoor unit (11) according to the comparison result. According to the invention, troubleshooting can be carried out on a multi-split air conditioner by utilizing a convenient way, so that there is no need to consume lots of manpower and material resources; therefore, a resource wasting problem caused by consumption of lots of manpower and material resources and time during troubleshooting on a multi-split air conditioning system in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of test and measurement, in particular to a multi-connected air conditioner detection system and method. Background technique [0002] The multi-connected air-conditioning (heat pump) system (referred to as: multi-connected) was born in 1982. Although it only has a development history of more than 20 years, it has independent control of indoor units, flexible use, good scalability, beautiful appearance, and small installation space. It has outstanding advantages such as no special machine room, and has become one of the most active forms of central air-conditioning systems. [0003] Since entering the 21st century, my country has become a big country in the production and application of multi-line products. The production scale, production and sales of multi-line machines have been advancing by leaps and bounds, and the quality of its products has also improved year after year. As a kind of multi-connection products,...
