Air conditioning system

Abstract

Provided is an air conditioning system that conditions the air inside the passenger compartment of an automobile mounted with a secondary battery or fuel cell that drives the wheels via a motor. Said air conditioning system comprises a catalytic heater, an air-conditioning duct, and an air-conditioning fan. The catalytic heater produces heat by supplying an oxidizing gas and a fuel to a catalyst. The air-conditioning duct is connected to an air intake and a vent, the air-conditioning fan is provided inside the air-conditioning duct, and air is circulated inside the passenger compartment. The provided air conditioning system uses the heat produced by the catalytic heater to condition the air inside the air-conditioning duct, thereby conditioning the air inside the passenger compartment. In automobiles mounted with a secondary battery or fuel cell that drives the wheels via a motor, such as electric automobiles, hybrid vehicles, and fuel cell automobiles, the provided air-conditioning system reduces the use of the power from the secondary battery or the like for heating, thereby preventing the driving range or life from decreasing and allowing efficient conditioning of air.

Description

technical field [0001] The present invention relates to an air-conditioning system for a vehicle that uses a secondary battery or a fuel cell to drive wheels with a motor, such as an electric vehicle, a hybrid (gasoline engine + electric) vehicle, or a fuel cell vehicle. Background technique [0002] Previously, electric vehicles or hybrid vehicles, fuel cell vehicles, etc., used electric heaters for heating, for example, using PTC (ceramic electric heating) heaters to warm circulating water, or using PTC heaters to directly warm air way (refer to Patent Document 1). [0003] However, since these cars have less waste heat from the engine than gasoline cars, in the case of electric cars, for example, when air conditioning is performed, the heater consumes electricity charged in the secondary battery. Furthermore, heat transfer heaters such as PTC heaters consume large amounts of power. [0004] In this way, since electric power of the secondary battery and the like is trans...

AI Technical Summary

Problems solved by technology

It also accelerates the consumption of fuel in the fuel cell

[0005] In addition, a heating system using a heat pump method was also considered, but if the outside air temperature is low, the efficiency will drop significantly

Also, since heat is drawn from the outside air for heating, if the outside air temperature is too low, there will be a problem of freezing of the heat exchanger

In particular, in cold regions where heaters are required, the efficiency of heat pump heaters drops significantly
