  "textContent": "Provided is an air-conditioning control device that controls an air-conditioning device including: a heat exchanger that exchanges heat between a refrigerant discharged from a compressor and a heating medium; and an opening and closing portion that opens and closes a refrigerant passage between the compressor and the heat exchanger according to a command. The air-conditioning control device is provided with: a pressure acquisition unit that acquires a detection value from a pressure sensor that detects the pressure of a refrigerant flowing through the heat exchanger; a temperature acquisition unit that acquires a detection value from a temperature sensor that detects the temperature of a heating medium flowing through the heat exchanger; and a determination unit that, in the case where a command is issued to cause a refrigerant to flow through the opening and closing portion in a state where the refrigerant is not flowing through the opening and closing portion, determines whether or not the opening and closing portion is normally opened to cause the refrigerant to flow through the heat exchanger, by using the pressure of the refrigerant detected by the pressure sensor and the temperature of the heating medium detected by the temperature sensor.",
