Document Type and Number:
WIPO Patent Application WO/2022/230758
Kind Code:
A1
Abstract:
[Problem] The purpose of the present disclosure is to provide a heating control device capable of performing control with small fluctuations in temperature with respect to the target temperature and such that a target temperature is rapidly reached, and also to provide a heating cycle device and a vehicle air conditioner equipped therewith. [Solution] A heating control device 6 according to the present disclosure controls a transistor 5 that supplies power by switching operation to a heater 4 that heats a coolant, the heating control device adjusting the heating amount of the heater on the basis of a heating amount control profile that has a decreasing portion in which the heating amount decreases as the coolant temperature rises, the decreasing portion having a first decreasing portion and a second decreasing portion each having a negative slope, the first decreasing portion and the second decreasing portion having the same heating amount at the target temperature, the first decreasing portion having a first region and a second region, and the slope at any temperature within the second region being negative with respect to the slope at any temperature within the first region.
