The purpose of the present disclosure is to provide a heating control device and control program, a fluid heating unit, a heating cycle device, and a vehicle air-conditioning device provided with a heating cycle device, whereby it is possible to appropriately ascertain that the amount of heat medium supplied is less than a prescribed flow rate. This heating control device (6) stores a temperature rise map indicating the relationship between the flow rate of the coolant and the rate of temperature rise of the coolant on the downstream side of a heater (4) when the amount of heating by the heater (4) is a prescribed amount. In the heating initial mode, the temperature increase rate of the cooling liquid is calculated on the basis of the temperature of the cooling liquid detected by the first temperature detection device (51), and the temperature increase rate of the cooling liquid is calculated on the basis of the temperature of the cooling liquid detected by the second temperature detection device (51). An estimated flow rate of the cooling liquid corresponding to the calculated temperature rise rate is derived on the basis of the temperature rise map.
本公开的目的在于提供一种能够适当地掌握热介质的供给量比规定的流量少的情况的制热控制装置以及控制程序、流体加热单元、制热循环装置以及具备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存储有表示加热器4的加热量为规定量时加热器下游侧的冷却液的温度上升速度与冷却液的流量之间的关系的升温映射,且具有在从向加热器的通电开始时到冷却液温度达到规定温度时为止的期间内执行的制热初始模式,在制热初始模式下,基于第一温度检测装置51检测的冷却液的温度来算出冷却液的温度上升速度,基于升温映射来导出与算出的温度上升速度对应的冷却液的推定流量。
