The purpose of the present disclosure is to provide a heating control device, a heating cycle device, and a vehicle air-conditioning device provided with the heating cycle device, whereby it is possible to achieve a target temperature in advance and to perform control such that temperature fluctuations with respect to the target temperature are small. This heating control device (6) controls a transistor (5) that supplies power to a heater (4) that heats a cooling liquid by means of a switching operation, the heating control device adjusting the amount of heating of the heater on the basis of a heating amount control curve having a reduction unit in which the amount of heating decreases as the temperature of the cooling liquid increases. The reduction portion has a first reduction portion and a second reduction portion, the first reduction portion and the second reduction portion each have a negative slope, and the first reduction portion and the second reduction portion have an equal heating amount at a target temperature, the first reduction portion having a first region and a second region, the slope at an arbitrary temperature in the second region is larger than the slope at an arbitrary temperature in the first region by a negative slope.
本公开的目的在于提供一种能够进行提前达到目标温度且相对于目标温度的温度变动小的控制的制热控制装置、制热循环装置以及具备该制热循环装置的车辆用空调装置。本公开的制热控制装置6对通过开关动作向加热冷却液的加热器4供电的晶体管5进行控制,其中,制热控制装置根据加热量控制曲线来调整加热器的加热量,加热量控制曲线具有随着冷却液的温度上升而加热量减少的减少部,减少部具有第一减少部和第二减少部,第一减少部和第二减少部均具有负的斜率,且第一减少部和第二减少部在目标温度处具有相等的加热量,第一减少部具有第一区域和第二区域,第二区域内的任意的温度处的斜率与第一区域内的任意的温度处的斜率相比负的斜率大。
