AIR COOLING SYSTEM
In this type of cooling system, the heat, which is conducted to the outer parts of the engine, is radiated and
conducted away by the stream of air, which is obtained from the atmosphere. In order to have efficient
cooling by means of air, providing fins around the cylinder and cylinder head increases the contact area.
The fins are metallic ridges, which are formed during the casting of the cylinder and cylinder head
The amount of heat carried off by the air-cooling depends upon the following factors
Air conditioning systems control the temperature, humidity, air movement and air cleanliness inside a building, in order to provide occupants a comfortable environment with good indoor air quality.
In general, air conditioning system can be categorized into room coolers and centralized systems.
Room coolers, such as window and split-type air-conditioners are most commonly adopted in residential buildings. The whole refrigerant cycle is completed within the room cooler machine. The figure below shows the interior structure of a window-type room cooler.
