Description

Solar car air conditioner

the

technical field

The invention relates to a solar car air conditioner, in particular to the combination of solar energy, car and air conditioner.

Background technique

Automobile air conditioners are refrigeration devices installed in automobiles, which are used to provide cold air in hot weather and bring comfort to people in the car. The solar car air conditioner converts sunlight into electrical energy through the photoelectric conversion effect, which is first stored in the battery, and then the battery drives the air conditioner compressor to achieve cooling. Solar car air conditioners have the advantages of saving traditional energy and protecting the atmospheric environment. Although the cooling effect of the existing automobile air conditioner is ideal, its compressor power comes from the automobile engine, so the power performance of the engine must be reduced when the air conditioning system works. Since the speed of the compressor changes with the speed of the vehicle, the air conditioner stops cooling when the car stops.

Contents of the invention

The purpose of the present invention is to alleviate the shortage of current traditional energy sources, reduce the pollution to the atmospheric environment, and provide a new type of solar car that utilizes solar energy to drive the car and the vehicle-mounted air conditioner.

In order to achieve the above invention, the present invention adopts the following technical solutions: the present invention consists of a solar photovoltaic DC power supply system, a traditional refrigeration system, and an ECU control system; the solar photovoltaic DC power supply system consists of a solar panel (10), a voltage sensor (d ), the battery (2); the solar photovoltaic DC power system converts light energy into electrical energy to charge the battery (2) in the form of direct current, and the battery in turn provides electricity for the refrigeration system; the battery (1) and the battery (2) are Connected and controlled by a switch, they are the DC power supply of the refrigeration system when there is insufficient sunlight, and the ECU (11) controls the charge and discharge of the battery (2) and cooperates with the temperature sensor to adjust the temperature in the cab of the car and control parking when the fan is running.

The refrigeration system consists of an evaporator (8), a compressor (5), a condenser (6), an expansion valve (7), and a storage battery (2). The cold end of the refrigeration system is set in the cab. When the air conditioner is running, the forced convection of the evaporator (9) and the cooling fan cools and cools the cab (c) of the car. The refrigerant cools down with the cold air in the condenser (6). For heat exchange, the application of air-cooled radiator can avoid the use of circulating water and reduce the weight of the whole vehicle. The working medium in the evaporator (8) is vaporized into a gas due to heat absorption, and the working medium gas is compressed by the compressor (5) and then flows to the condenser (6), where the heat is transferred to the external flowing air in the condenser. When the car is running, the radiator faces the wind to increase the flow of air to enhance heat exchange.

The main feature of the present invention is the effective combination and separation of the motor driving the motor and the motor driving the compressor. When the sun is sufficient, the solar panel (10) converts solar energy into electric energy to charge the battery (2), and the battery (2) directly provides the power source for the air conditioning system, and the voltage detector in the battery (2) The voltage is detected, and the detected value is transmitted to the ECU. When it is fully charged, the automatic control switch (B) will be disconnected, and the charging of the battery (2) will be stopped, and the battery (1) will be charged instead. The storage battery (1) directly provides the power source for the vehicle. When parking, the solar panel directly provides power for the cooling fan to enhance the air flow in the cab and avoid the phenomenon that the temperature in the cab rises sharply after parking. When the sunlight is insufficient, the automatic control switch (B) is always closed, and the storage battery (2) can directly supply high-voltage alternating current through the storage battery (1) to supplement electric energy.

The beneficial effect of the present invention is that the solar battery panel (10) can be flexibly placed on the roof and other places that do not affect the running of the car, and is connected to the battery (2) through a wire connector, and the battery (2) can be connected to the battery (1) The external AC power supply is connected, so that the present invention can adapt to changeable meteorological environments, and the applicability is greatly increased. Of course, solar cell films can also be pasted on the windows to increase the sunlight area and absorb more solar energy. The invention does not need traditional energy to provide power, and has no pollution to the environment, so it will be loved by consumers in the future.
