We use air-conditioner to beat the heat in hot weather. Temperature around the globe is on the rise and everyone feels the need to have air-conditioners in homes, cars, schools, offices, theaters, shopping malls, etc. Most cities are becoming temperate regions due to many reasons. Sun’s radiation and electrical appliances at homes/offices are the chief sources for getting heat and that cause discomfort to individuals. We use air conditioners for better health, to increase work efficiency and to get clean air. In this article, we will discuss how an air conditioner works to give you comfortable temperature levels at your home.
Air-conditioners have two or more units to bring your room temperature down. Most air-conditioners have an inside unit and an outside unit. The inside unit is technically known as evaporator and is placed inside the house. The outside unit is technically known as condensing unit and usually placed outside home and it consists a condenser coil, compressor coils and a fan.
By looking at these parts one may think the background mechanism is complex but, it is fairly simple. The main principle behind cooling your room depends on cycle of conversion of the refrigerant that is, gas into liquid and vice versa (expansion and contraction of the gas). During the process, it removes the heat and lowers the room temperature by bringing it to comfortable level.
Cooling mechanism starts in compressor (outdoor unit). In this unit refrigerants (gases like iso-butane and propane) circulate in coils as a cool gas under low pressure. The compressor raises temperature to convert this cool gas into hotter and it becomes a high pressured gas. The condenser unit helps dissipate the heat from refrigerant/gas. When high pressured hot gas enters into the condenser coil, it removes the heat from the gas and thus it converts gas in to liquid. The fan provided in the outside unit assists condenser to pull the heat from refrigerant to help it get converted into liquid.
Now, the liquified gas enters into indoor unit or evaporator. When liquified gas gets circulated in the evaporator’s coil, it absorbs, the heat and moisture from the room and provides cooling effect. The liquified gas once absorbs the heat in the house, it becomes a cool low-pressure gas and enters into the compressor again to begin the cycle. The process continues as a cycle and gives a comfortable room temperature.
Another system attached to the evaporator unit is the drainage device. When evaporator absorbs heat and moisture from the house, it produces water as a by-product, which is removed from this drainage system.
All these units need to work appropriately to provide comfortable level of temperature in your room.
