The invention provides a waste heat utilization control method and device and a waste heat utilization system. The method is applied to a controller in the waste heat utilization system, the waste heat utilization system further comprises a heating loop, the heating loop is provided with a heat exchanger, a warm air radiator and a water pump, and the method comprises the steps of: detecting whether first heating equipment is in a heating mode or not; if the first heat supply equipment is in the heat supply mode, further detecting whether the power of the fuel cell is greater than the set poweror not; if the power of the fuel cell is greater than the set power, determining whether a waste heat utilization starting condition is met or not according to the temperature of the passenger compartment and a preset first temperature; and if the waste heat utilization starting condition is met, controlling the warm air radiator to dissipate heat in the heating loop to the passenger compartment.According to the waste heat utilization control method provided by the invention, the heat generated by the fuel cell can be used for the passenger compartment, so that the economy of the fuel cell vehicle is improved, and the fuel consumption is reduced.

    本申请提供了一种余热利用控制方法、装置及余热利用系统,其中,方法应用于余热利用系统中的控制器,余热利用系统还包括供暖回路,供暖回路设置有换热器、暖风散热器和水泵,方法包括:检测第一供热设备是否处于供热模式;若第一供热设备处于供热模式时,则进一步检测燃料电池的功率是否大于设定功率;若燃料电池的功率大于设定功率,则根据乘客舱的温度和预设的第一温度确定是否满足余热利用开启条件;若满足余热利用开启条件,则控制暖风散热器将供暖回路中的热量散至乘客舱。本申请提供的余热利用控制方法可将燃料电池产生的热量用于乘客舱,这使得燃料电池汽车的经济性得以提高,燃料消耗得以降低。
