FUEL CELL VEHICLE AIR-CONDITIONING APPARATUS AND CONTROL METHOD THEREOF

摘要

A fuel cell vehicle air-conditioning apparatus includes: a cooling system that adjusts a temperature of a fuel cell; a waste heat collection unit that collects at least a part of waste heat from the fuel cell and uses the collected waste heat to heat a cabin interior of the fuel cell vehicle; and a heat creation unit that creates heat for heating the fuel cell vehicle. The fuel cell vehicle air-conditioning apparatus calculates a fuel consumption amount required for the fuel cell to generate a total power generation amount, which is a sum of a heating power generation amount and a travel power generation amount, calculates an optimum temperature, which is a temperature of the fuel cell at which the fuel consumption amount reaches a minimum, and controls the cooling system such that the temperature of the fuel cell reaches the optimum temperature.

1. A fuel cell vehicle air-conditioning apparatus comprising:
a fuel cell that generates power by an electrochemical reaction between an oxidant gas and a fuel gas; a cooling system that adjusts a temperature of the fuel cell; a waste heat collection unit that collects at least a part of waste heat from the fuel cell via the cooling system and uses the collected waste heat to heat a cabin interior of the fuel cell vehicle; a heat creation unit that creates heat for heating the fuel cell vehicle; and a control apparatus including:
a stored heat amount calculation unit configured to calculate an amount of stored heat in the fuel cell;a reference time required heating heat amount calculation unit configured to calculate a required heating heat amount that is an amount of heat required to perform required heating for a predetermined reference time;a heating power generation amount calculation unit configured to calculate a heating power generation amount that is an amount of power generation by the fuel cell required for the heating to be performed by the heat creation unit, on the basis of the required heating heat amount and the amount of stored heat in the fuel cell;a travel power generation amount calculation unit configured to calculate a travel power generation amount that is an amount of power generation by the fuel cell required for the fuel cell vehicle to travel;an optimum temperature calculation unit configured to calculate a fuel consumption amount required for the fuel cell to generate a total power generation amount that is a sum of the heating power generation amount and the travel power generation amount, and calculate an optimum temperature that is a temperature of the fuel cell at which the fuel consumption amount reaches a minimum; anda control unit configured to control the cooling system such that the temperature of the fuel cell reaches the optimum temperature.
