In this ppt , we will discuss about
1- Duct for Air conditioning system
2-Cooling system of transverse and rear engine vehicles
are explained very clearly with pictures.
3. In Olden Days,air- conditioning is used as luxurious and
comfort purpose, but now-a-day, it has been common and
a necessity in extreme climatic conditions, such as extreme
cold and hot in western countries.Window air conditioners
are preferred for office rooms while large centralized units
are installed for conditioning the auditorium, hospitals etc.
INTRODUCTION
4. Air conditioning ducts
The purpose of air conditioning ductwork is to deliver air from the
fan to the diffusers which distribute the air to the room.
HVAC [Heating, ventilation, and air conditioning] system is very
essential accessory and keeps cool inside the vehicle.
7. Materials used for Ducts
Sheet metal (by gauge)
• Galvanized
• Iron
• Aluminum
Flexible
• Insulated
• Tube (socks)
8. Types of Mechanical Ventilation System
1. Ducted Ventilation System
2. Ductless Ventilation System
9. Disadvantages - Ducted Ventilation System
•Increased Installation & maintenance Cost.
•Higher Operating cost as entire area is ventilated
instead of focused area.
•Less ability to control the smoke.
•Aesthetically less pleasing.
12. Cooling of Transverse engine and Rear Engine
•For both Transverse Engines and Rear engines same
type of cooling systems are used.
•Every IC engine requires cooling and lubrication
systems
13. HOW THE COOLING SYSTEM OF YOUR CAR
WORKS ?
• Engine is the only component in your car that can change the
chemical energy to the form of mechanical energy.
• But the 70%of the chemical energy turns into heat energy than the
mechanical energy.
• To avoid the heat and also to prevent from heat cooling systems are
introduced.
• Cooling system of a car can lowers the temperature of the engine , to
protect from damage other parts in our vehicle.
14. Components of cooling system
The cooling system of your car can consist of several different subsystems to
work. Such as:
• Coolant (Antifreeze)
• Cooling fan
• Cooling reservoir
• Heater core
• Hoses
• Thermostat
• Water pump
• Radiator
