The Working Principle of Air Conditioner (AC)

Broadly speaking, the working principle of the air conditioners is as follows:

1. The air in the room is sucked by a centrifugal fan is in contact with the air and the evaporator coil pipe containing refrigerant fluid. In this case the refrigerant absorbs heat to cool the air so that the air and the refrigerant evaporates and steam is collected in a container.

2. The vapor pressure coming from the evaporator is circulated to the condenser, during the compression process progresses, the temperature and pressure of refrigerant vapor to rise and pressed into the condenser.

3. To reduce the pressure of high-pressure liquid refrigerant expansion valve is used to regulate the flow rate of refrigerant into the evaporator.

4. At the time of the air out of the air condensing into heat. Steam delivers heat to the refrigerant in the cooling air condensing into dew on the capillary tube. In removing the heat on condensing, aided by a fan propeller.

5. In the cold air circulation in the room constantly, hence the need for the thermostat to regulate the temperature in the room or liking.

6. The air in the room to be colder than outdoors because indoor air is sucked by a centrifugal contained in the evaporator and then going on the air in contact with the pipe / Coill evaporator in which there are gas refrigerant (Freon). Here the heat transfer so that the indoor air temperature is relatively cool than before.

7. The outdoor temperature is hotter than indoors, because indoor air is sucked by a centrifugal fan and in contact with the evaporator, and assisted with other air conditioning components, then the indoor air expelled by the fan air condenser. In this case the outdoor air can be inhaled by the centrifugal fan and the entry of air through the grille found on the AC.

8. The current high-temperature refrigerant gas is compressed at the end of the condensor easily liquefied by cooling air to the water system or steam cooled refrigerant absorbs heat in the condenser cooling air that condenses and becomes liquid outside the pipe evaporator.

9. Because the water or the air conditioner absorbs heat from the refrigerant, the water or the air becomes hot at the time out of the condenser. Vapor refrigerant that has become liquid, then poured into the pipe evaporator through the expansion valve.

This event will be repeated as above.

How does the air conditioning system so as to provide a cooling effect in your room? AC alias alias Pengkondision Air Conditioner Air is a set of tools that is able to condition the room that we wanted, mainly conditioned room becomes a lower temperature than the temperature of the surrounding environment. The set of tools including a compressor, a condenser, orifice tube, evaporator, expansion valve and evaporator with the following explanation:

Compressor :

The compressor is the power unit of an air-conditioning system. When the AC is run,  ompresormengubah working fluid / refrigent form of low-pressure gas into high yangbertekanan gas. High-pressure gas is then forwarded to the kondensor.

Kondensor: The condenser is a tool used to change / cool down high yangbertekanan gas turns into a liquid high pressure. Fluid then flows to orificetube.

Orifice Tube:where high-pressure fluid lowered the pressure and temperature into a liquid dinginbertekanan low. In some systems, in addition to installing an orifice tube, expansion valve is installed too.

Katup expansion: expansion valve, an important component of the system. It is designed to controlling the flow of  cooling fluid through the valve orifice that converts the liquid into vapor form when zatpendingin leaving expansion valve and entering the evaporator / cooling.

Evaporator / cooling: refrigent absorbs heat in the room through the cooling coils and fan evaporator blow cold air into the room. Refrigent in the evaporator began to change back into low-pressure steam, but still contain a small amount of liquid. Then refrigent  mixture into the accumulator / dryer. It It also can act as the mouth / second orifice for fluid liquid turns into a pure low-pressure steam, before going through the compressor to obtain pressure and circulating in the system again. Typically, silicon evaporator assemblying which serves to absorb moisture from refrigent.So that, how the air conditioning system can be described as follows.

The existing compressor in the cooling system is used as a tool for working memampatkanfluida (refrigent), so refrigent that goes into the compressor flows into condenser then compressed in this condenser section kondenser.In compressed refrigent will change the phase of refrigent refrigent vapor phase into a liquid phase, then refrigent issued a heat of vaporization heat is contained in refrigent. The amount of heat given off by the condenser is the sum of the energy required compressor and heat energy is taken evaparator of the substance to be cooled.

On the refrigent pressure condenser located in the condenser pipes are relatively much higher than the pressure that is on cheek refrigent refrigent evaporator.Setelah pipe through the condenser and releases heat of vaporization of the liquid phase to vapor phase then refrigent passed through the expansion valve, the expansion valve is refrigent pressure is reduced so that refrigent changing conditions of the liquid phase to vapor phase then dialirkanke evaporator, in this evaporator refrigent will change the situation from liquid phase to vapor phase, the phase change is caused due to the pressure created sedemikianrupa refrigent so refrigent after passing through the expansion valve and evaporator pressure becomes very turun.That was practically can be done with the existing pipe diameter relatively larger dievaporator when compared with that of the pipe diameter kondenser.Dengan refrigent the changing conditions of the liquid phase to vapor phase then to change from liquid phase to vapor phase refrigent then this process requires evaporation energy is energy, in this case the energy is the energy that is being used in substance to be cooled.

With energy taken taken in the substance to be cooled, the enthalpy [*] substance to be cooled will be dropped, with the decrease in enthalpy then the temperature of the substance to be cooled will be dropped. This process will change constantly until a cooling in accordance with keinginan.With the electric cooling machine is then to cool or reduce the temperature of a substance can be easily dilakukan.Perlu note: The key element of the air conditioner is refrigerant, which generally is a fluorocarbon [* *], that flows in the system, it becomes liquid and release heat when pumped (pressurized), danmenjadi gas and absorbs heat when the pressure is reduced. Mechanism of changing refrigerantmenjadi liquids and gases by giving or reducing the pressure divided becoming two areas: an air filter, fan and cooling coil (cooling coils) which is in sisiruangan and a compressor (pump), condenser coil (coil heat exchanger), and kipaspada luar.Udara window heat from the room through the filter, leading to a cooling coil containing cold refrigerant fluid, so that the air becomes cold, then through the grille / grille back into the room. In the compressor, refrigerant gas from the cooling coil and heated by means of compressing. In the condenser coil, refrigerant releases heat and becomes a liquid, which is circulated back to the cooling coil. A thermostat [***] controls the compressor motor to adjust the room temperature.
