A car ventilation and refrigeration system based on flexible photovoltaic sunshade

Abstract

The invention provides an automobile ventilation and refrigeration system based on a flexible photovoltaic sunshade curtain, and relates to ventilation and refrigeration of automobiles. The automobile ventilation and refrigeration system comprises an energy converting unit, a circuit protection unit, an energy storage unit, a monitoring system, a system management unit and an execution unit, wherein all the units comprise parts or modules as follows: the energy converting unit is provided with a flexible colored semitransparent organic polymer solar battery; the circuit protection unit is provided with a voltage stabilizing circuit, a rectifying circuit and an inverter circuit; the energy storage unit is a vehicle-mounted lead storage battery; the monitoring system is provided with an air quality detector, a temperature sensor and a battery power detector; the system management unit is provided with a charging and discharging control module and an execution control module; and the execution unit is provided with a vehicle-mounted air conditioner and a fan. The energy converting unit is arranged behind a windshield, and the circuit protection unit, the energy storage unit, the monitoring system, the system management unit and the execution unit are arranged in a control booth. The automobile ventilation and refrigeration system disclosed by the invention is simple to operate and convenient to store; the problems that temperature in the compartment of the automobile is too high and air quality is poor when the automobile is in a parking state in summer are solved, and potential risks caused by too high temperature in the compartment and poor air quality are eliminated, so that the automobile ventilation and refrigeration system is beneficial to health of human; and besides, the automobile ventilation and refrigeration system is energy-saving and environmentally-friendly, and meets the age demand for sustainable development.

Description

technical field [0001] The invention relates to automobile ventilation and refrigeration, in particular to an automobile ventilation and refrigeration system based on a flexible photovoltaic sunshade. Background technique [0002] In summer, when the car is parked in the open air, due to the narrow space and airtightness of the compartment, and the body is made of metal, under strong sunlight, especially when the strong light shines directly on the compartment from the windshield, the temperature inside the compartment can easily reach over 60°C . When the car owner returns to the car, there will be obvious discomfort; moreover, the temperature of the seat surface in the car is also very high. In addition, industrial products such as seats and seat covers, consoles and floor mats in the compartment may release harmful chemicals such as formaldehyde and acetaldehyde at high temperatures, which will have a direct impact on the health of car owners. The usual way for car owne...

Problems solved by technology

[0003] The Chinese invention patent with the patent application number 201610174984.4 "A vehicle ventilation and cooling system and method using solar energy" provides an idea to solve the above problems, but the invention only proposes a few general functional modules without specific implementation In particular, the technical features of the energy conversion module are not described; the Chinese utility model patent "A Solar Vehicle Windshield Sunshade Control System" with the patent application number of 201520123727.9 discloses that the windshield sunshade has a complicated structure due to the addition of a motor , it uses the folding of the sunshade to control whether the charging and discharging are not efficient enough and there are loopholes. If the battery is fully charged, once the sunshade is folded, the sunlight will still directly enter the windshield, causing the cabin temperature to rise.
