Abstract

The embodiment of the invention discloses a detection method for a PTC heater of an air conditioner and a detection device thereof. The detection method comprises the steps that the heating model of the PTC heater is pre-established, and the heating model includes at least one normal working range of the PTC heater; whether the acquired power of the PTC heater exceeds at least one normal working range is detected in real time; and an alarm instruction is transmitted to trigger alarm if the judgment result is yes. According to the detection method for the PTC heater of the air conditioner and the detection device thereof, the heating model of the PTC heater is preset, the power of the PTC heater of the air conditioner is detected in real time according to the heating model, and alarm is timely performed when the power exceeds the normal working range so that abnormality detection and alarm of the PTC heater can be realized, detection and alarm of all types of abnormality of the PTC heater can be realized, users can timely take effective processing measures according to the alarm to eliminate possible fire and other accidents, and safety monitoring and protection of the air conditioner and the PTC heater thereof can be realized.

Description

technical field [0001] Embodiments of the present invention relate to air-conditioning technology, and in particular to a detection method and device for a PTC heater of an air-conditioner. Background technique [0002] An auxiliary heat source device is usually configured in an air conditioner, and the ideal and common auxiliary heat source device is an auxiliary heater. The auxiliary heater in the air conditioner is used to preheat the water medium, thereby improving the heating effect and working effect of the air conditioner during and before operation. [0003] Most of the existing auxiliary heaters are heaters using conventional resistive heating elements, and some auxiliary heaters are PTC heaters designed using the constant temperature heating characteristics of positive temperature coefficient (PTC) thermistors. The air conditioner is equipped with a fault detection and protection circuit, which is used to detect the fault of the auxiliary heater through temperatur...
