Air Conditioning System............... brrrrrr its cold :9

have you ever thought how do you ever get the cold feeling from ac's well i have your answer right here please continue reading :D

lets learning the meaning of the word we always use at home "ac" and that is Air conditioning (often referred to as aircon, AC or A/C) is the process of altering the properties of air (primarily temperature and humidity) to more favorable conditions. More generally, air conditioning can refer to any form of technological cooling, heating, ventilation, or disinfection that modifies the condition of air + its a major important unresistant device we, especially in Oman, in summer.

whats the parts of this small magic box ? well there quite a few, and there:-

• Evaporator - Receives the liquid refrigerant

• Condenser - Facilitates heat transfer

• Expansion valve - regulates refrigerant flow into the evaporator

• Compressor - A pump that pressurizes refrigerant

Now lets how does this process happen, shall we ?

The cold side of an air conditioner contains the evaporator and a fan that blows air over the chilled coils and into the room. The hot side contains the compressor, condenser and another fan to vent hot air coming off the compressed refrigerant to the outdoors. In between the two sets of coils, there's an expansion valve. It regulates the amount of compressed liquid refrigerant moving into the evaporator. Once in the evaporator, the refrigerant experiences a pressure drop, expands and changes back into a gas. The compressor is actually a large electric pump that pressurizes the refrigerant gas as part of the process of turning it back into a liquid. There are some additional sensors, timers and valves, but the evaporator, compressor, condenser and expansion valve are the main components of an air conditioner. 

^^ interesting isn't it ?i hope this review helped you clear some doubtsoh this is sudden but if you ever have a question you want to know the answer please tell me ill be glad to help 

Identify the main parts of control heating system

     1- Boiler:- heats water in a closed-water system

     2- Cylinder: - it’s a huge tank that carries the water supply.

     3- Pumps: - circulates the water in the closed system, it      also reduces the cooling down of the hot water.

     4- Radiator: - wall-mounted panels through which the    heated water passes in order to release heat into rooms.

Recognize the role of ICT in this system.

The role of ICT in this system use of varies devices started from the sensors. The sensors picks up and senses the analog signals in the water, and here comes the use of the next devise which is ADC analog digital converter were the analog signals are being converted to digits so that a computer can pick up these digital codes and sees the requirement of the user, is it the temperature he asks or not? Than it changes the require changes and is sent to the DAN were the digits sent are being converted to analog signals and received by the accumulator which then gives orders to the system.

   

Control system......... is a lifesaving system

Control system has a huge role in the current time were living and in future too, but before going to details we should understand the meaning of "control system" which means A control system is a device, or set of devices, that manages, commands, directs or regulates the behavior of other device or system. Industrial control systems are used in industrial production for controlling an equipment or a machine.

Control system is used everywhere around us like in AC’s, robots and in many second industry factories, commonly in car manufacturing, which is going to be our highlight for today’s topic.

The hardware’s of controlling system of car manufacturing are:

The arms

The joints

The stepper motor

The end effector

The software:

The special controlling software in the microprocessor or computer that involves all the duties of the system.

There are lots of end effectors in this “control system” world but the most common ones with the robots involved in the car manufacturing industries are:

1  1- Impactive – jaws or claws which physically grasp by direct impact upon the object.

    2- Ingressive – pins, needles or hackles which physically penetrate the surface of the object (used in textile, carbon and glass fibre handling).

3  3- Astrictive – suction forces applied to the objects surface (whether by vacuum, magneto- or electro-adhesion).

    4- Contigutive – requiring direct contact for adhesion to take place (such as glue, surface tension or freezing).

These are individual and each end effector used by robots in this car manufacturing with explanation of its functions.
