Problems solved by technology
However, this method can usually only judge whether the connection port of the temperature sensor is open or short circuited, and it cannot be judged if the detected value of the temperature sensor and the actual temperature value have a large deviation but have not yet reached the short circuit or open circuit.
In the case of such a large deviation, the temperature sensor is actually invalid, because this situation is likely to cause abnormal control of the heat pump system

The invention relates to a temperature sensor failure judgment device and method of a heat pump system, and the heat pump system. The device comprises a first temperature sensor and a processor connected with the first temperature sensor. The first temperature sensor is used for detecting the environment temperature of an object detected by a to-be-judged temperature sensor. The processor is suitable for connection with the to-be-judged temperature sensor and used for acquiring the temperature of the object detected by the to-be-judged temperature sensor and the environment temperature when the heat pump system stops, and judging whether the to-be-judged temperature sensor fails according to the temperature of the object and the environment temperature. According to the invention, a condition can be detected that the difference between a detection value and an actual temperature value is quite big but the short circuit or the disconnection does not occur, i.e., whether the to-be-judgedtemperature sensor fails truly is effectively judged, so the control abnormity of the heat pump system is avoided.
Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to a heat pump system temperature sensor failure judgment device, a heat pump system temperature sensor failure judgment method and a heat pump system. Background technique [0002] In the field of heat pump technology, it is necessary to detect the temperature of each part of the heat pump system, and then rely on the detection results for system control. Therefore, an accurate judgment must be made on the working status of the temperature sensor, and the control system must know whether the detection result of the temperature sensor is Reliable, whether the sensor fails. [0003] The traditional judgment method is to detect whether the terminal voltage or current of the temperature sensor is within the specified working range, so as to determine whether the temperature sensor is damaged or invalid. However, this method can usually only determine whether the connection port of ...
