Capacitor Research Paper

The word system has become very popular nowadays. It is not only applicable in engineering but also in science, economics, and sociology. A system is defined as a combination of components that act together to perform a certain objective. It is also can be understood as a conceptually isolated part of the universe that is of interest to us. All existing systems change with time and when the rates of change are significant, the systems are referred to as dynamic system. The isolation of the system from the environment is purely conceptual. Every system interacts with its environment through two groups of variables which are input and output. Input is the variables in the first group originate outside the system and are not directly dependent

It consists of two terminals in which the starting the running terminal of the compressor is connected. As the current enter the capacitor from the second line of the source, the store energy will be released into the starting terminal and activates the starting winding. Every capacitor has different capacity depending on the electric motor where it is being used with. There are two types of capacitor namely mono capacitor and dual capacitor. Fan capacitor, running capacitor and starting capacitor are mono capacitor because they have two terminals for starting and running. Each of these capacitor has their own function, for example, fan capacitor is used to help activating the electric motor that drives the blower condenser and evaporator. Dual capacitor is a combination of fan and run capacitor that drives both compressor and fan motor which are commonly used in window air conditioning unit. It has three groups of terminals, one for auxiliary terminal of the fan motor indicated with the word “fan” and the other is for the starting terminal of the compressor marking with “herm”. The center terminal function as the running terminal of the compressor and common terminal of the fan motor. It is commonly used is serving both compressor and fan motor at the same

The heat transfer between the particles of the solid materials causing each particle to heat up in turn. Heat convection is the heat transfer means by which the molecules or atoms of a liquid or gas move in a circular motion and carrying heat. Radiation is the heat transfer means by which waves located in the infrared potion of the spectrum transfer heat with or without a medium. In our project, we know that heat transfer take place in the evaporator and the condenser of air conditioner. In the evaporator, a fan blows the warm air which is to be cooled across the evaporator coil, causing the liquid part of the refrigerant to evaporate, heat in the warm air is then carried away by the cold refrigerant and thus lowering its temperature. In this case, the heat transfer is in convection method which occur between the hot warm air and the coil of evaporator where liquid refrigerant flowing through it.
Besides that, heat convection also occur in the condenser of air conditioner. In a condenser, hot and compressed refrigerant vapor is cooled by the air flowing across the condenser coil. Similarly, heat convection take place between the cool air and the coil of condenser where vapor refrigerant flowing through it. In addition, heat conduction occur in the condenser when it rejects heat to the environment using the air conditioner cover as a medium of transferring
