PROBLEM TO BE SOLVED: To provide a hybrid air conditioning control device that can efficiently operate an air conditioner having air-cooled and water-cooled heat exchangers and cause it to function as an air conditioner even when either heat exchanger fails. SOLUTION: The device is for controlling a hybrid air conditioner 1 having a first path 4B with an air-cooled heat exchanger 5 for heat exchange via gas with a heat exchange medium circulated in a passage 4 for circulating the heat exchange medium to and from air conditioning equipment 11, a second path 4A with a water-cooled heat exchanger 20 for heat exchange via cooling water with the heat exchange medium circulated in the passage, switch means 22 to 25 for switching the path in which the heat exchange medium flows to the first path or second path, and a cooling water path 30 for circulating the cooling water to the water-cooled heat exchanger 20. The switch means are controlled to switch the path in which the heat exchange medium flows to the first path 4B if temperature information from temperature detection means 32 and 33 for detecting the temperature of the cooling water exceeds at least an upper limit temperature or upper limit temperature range, and to switch the path in which the heat exchange medium flows to the second path 4A if the detected temperature information falls below a lower limit temperature or lower limit temperature range.
