Pure electric vehicle air conditioning system using fuel heater and temperature adjustment method

Abstract

The invention discloses a pure electric vehicle air conditioning system using a fuel heater and a temperature adjustment method, which belong to the field of the pure electric vehicle air conditioning systems. The technical scheme of the air conditioning system is that: the air conditioning system comprises an air conditioning body and the fuel heater connected with the air conditioning body, wherein an air outlet of the air conditioning body is provided with a temperature sensor; the temperature sensor and the fuel heater are connected with an ECU; the air conditioning body is connected with a fan through an electric valve; and the electric valve and the fan are connected with the ECU. The embodiment of the invention controls the switching of the fuel heater between a first gear and a second gear or controls the opening of the electric valve by the ECU of a control system so as to accurately adjust the temperature of warm air blown out of the air conditioning body and adjust the temperature in a cabin to a set value in real time to make constancy of the temperature in the cabin, thereby improving the comfort of passengers in a pure electric vehicle, and simultaneously reducing unnecessary fuel consumption, saving fuels and reducing the using cost of the pure electric cost by the accurate temperature adjustment.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicle air conditioning systems, in particular to a pure electric vehicle air conditioning system using a fuel heater and a temperature adjustment method. Background technique [0002] Traditional fuel heaters are installed on gasoline / diesel vehicles. In the cold winter, when the driver needs to use the vehicle, the engine system is warmed up in advance, the temperature in the cabin is increased, and the window is defrosted and defogged. , so there are only two fire adjustment gears. When the fuel heater is used in a pure electric vehicle, its function has changed. It is to continuously provide air-conditioned warm air to the cabin during the driving process of the vehicle. Therefore, the temperature of the warm air must adapt to the needs of the human body in the cabin and cannot exceed The high is too low, but the fuel heater only has two fire adjustment gears, and it is impossible to a...

Problems solved by technology

When the fuel heater is used in a pure electric vehicle, its function has changed. It is to continuously provide air-conditioned warm air to the cabin during the driving process of the vehicle. Therefore, the temperature of the warm air must adapt to the needs of the human body in the cabin and cannot exceed High is too low, but the fuel heater only has two fire adjustment gears, so it is impossible to achieve precise temperature control

[0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: when the fuel heater is used in the air-conditioning system of a pure electric vehicle, it cannot provide warm air with a suitable and constant temperature to the cabin
