Problems solved by technology

However, in the fixed-frequency external unit, since the tube temperature sensing package is in a suspended state and is not connected to the controller in the external unit, it is impossible to detect whether the tube temperature sensing package has come out of the casing, and it is also impossible to judge the tube temperature sensor. Is the thermostat working properly?

Embodiments of the present invention provide a detection device, a method and a test tool for detecting the abnormal operation of the tube temperature sensing package in the air-conditioning equipment. The detection device includes: an environmental temperature sensing package; a first detection module, connected to the environmental temperature sensing package, for obtaining the first resistance signal of the environmental temperature sensing package; a second detection module, for obtaining the pipe temperature in the air conditioner The second resistance signal of the temperature-sensing package; the control module is connected with the first detection circuit and the second detection circuit respectively, and is used to determine the temperature of the environment according to the first resistance signal, and determine the temperature of the tube temperature temperature-sensing package according to the second resistance signal temperature, and judge whether the temperature of the tube temperature sensing temperature package conforms to the preset rules according to the temperature of the environment; the output module is connected with the control module, and is used to output when the control module determines that the temperature of the tube temperature sensing temperature package does not meet the preset rules The first prompt information, the first prompt information is used to prompt that the tube temperature sensor temperature bulb is working abnormally.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a detection device, method and test tooling. Background technique [0002] Refrigerants are used in refrigeration and air-conditioning systems to transfer heat energy and produce refrigeration effects. In recent years, air-conditioning refrigerants have been gradually switched to R410a and R32 refrigerants. Compared with R410a refrigerant, R32 refrigerant system has better thermal performance, and its cooling capacity and energy efficiency are greatly improved compared with R410A system, while its heating capacity and energy efficiency are comparable to R410 system. [0003] In terms of structure, the R32 refrigerant external unit uses a tube temperature sensor instead of a high and low pressure switch, and the tube temperature sensor is connected to the pipeline through a sleeve. In the actual production process, the tube temperature sensor may fall out of the casing due t...
