Air conditioning device in car carriage

Abstract

An air conditioning device in a car carriage comprises a hollow pipe I, a hollow pipe II, a small-sized wind power generator and a storage battery pack; one end of the hollow pipe I is arranged at the front end of a car body and is of an air inlet end while the other end is arranged at the rear end of the car body and is of an air outlet end; one end of the hollow pipe II is communicated with the middle section of the hollow pipe II while the other end is arranged in a driving cab; a shunting valve is arranged at the crossing port of the hollow pipe I and the hollow pipe II; the air inlet end of the hollow pipe I is a flared opening and is communicated with the outside; the air outlet end of the hollow pipe II is provided with the small-sized wind power generator; the small-sized wind power generator is connected with the storage battery pack. The air conditioning device in the car carriage can avoid the air door problem of the existing natural ventilating device, the air pressure at the front peripheral part of the car body is reduced while the air pressure at the rear peripheral part of the car body is increased, and the air flow resistance of a car is reduced; meanwhile, the power generator and the power storing device are mounted, so the pressure difference between the front peripheral part and the rear peripheral part of the car is utilized for generating and storing power to be used for other purposes of the car.

Description

technical field [0001] The invention relates to the field of fluid dynamics, in particular to an air conditioning device inside an automobile compartment. Background technique [0002] The environment inside the car belongs to the mobile indoor microenvironment. The air environment inside the car is polluted by harmful substances from inside and outside the car. When the CO2 exceeds 1.5%-2.0%, people's breathing becomes rapid. Mild headache, disruption of electrolyte balance in the body. CO 2 When the content is 2.0-3.0%, the headache is exacerbated, dyspnea, and unresponsive. When it exceeds 5%, there is a risk of coma and death. CO in my country's indoor air quality standards 2 The limit is 0.10%. A person who works while sitting can exhale 18L / hCO 2 , the internal volume of the car is usually 3m 3 . [0003] The basic content of air conditioning is to adjust air temperature and humidity, organize reasonable air distribution, and improve air cleanliness to make the...

Problems solved by technology

However, after this kind of ventilation device has been used for a period of time, the damper of the air inlet at the front end is likely to be not closed tightly, which will cause air leakage in the winter compartment.
