Air-conditioning in the bodies and the impact of construction of the bodies on the safety of the car

The air conditioning system, used to comfortable cars and coaches, used for heating, ventilation and control humidity in the body. Fan pumps air through the outdoor air and the recluse of the body through a recluse in a cooler, from which it then goes through the hatches into the body. The number of incoming outside air control valve. In the cooler air absorbs heat from the cooling fluid (eg, Freon-12) during its transition to a vapor state. Pairs of coolant from the coolant pass to the compressor, where they are compressed. From the compressor, compressed and heated by a pair fed to the radiator, where they are cooled counter flow of air into a liquid, which flows into the receiver. From the receiver again enters the liquid refrigerant, having passed the filter. Automatic control system by-pass valve, bypass of the vapor, bypassing the radiator, which reduces the cooling capacity of the installation. The system has two thermostatic switch: one of them, depending on air temperature in the cooling control valve, the other - off the drive compressor with air cooler overcooling. Design development bodies, to improve the safety of the vehicles include a range of active measures to prevent accidents, and passive, protecting from injury occupant vehicle crashed. By active measures (active safety) are: excellent review and visibility from the driver's seat in all directions, a large area of ??the windshield wiper cleaning, wind protection, rear and side windows from freezing, lack of glare from the polished surfaces of the car, bright signals and stop- signals, comfortable seating position that enables him long work without fatigue, decrease brake pedal and the introduction of automated driving. To passive activities (passive safety) concern: safety belts (seat belts), shatterproof glass and wrought wheels, instrument panels with high-energy handling capability and recessed devices, buttons and other details, designs that provide the opportunity to enter a person from a wrecked car, high strength passenger compartment, to warrant a slight deformation in case of accidents; bumpers with rubber blocks that absorb shocks during collisions; Upholstery fireproof materials.
