Air conditioner and Refrigerators

Air conditioning and Refrigerator

An air conditioner is used for air conditioning that means decreasing heat and humidity in a certain area or a vehicle. It gives us much more comfortable environment air conditioner gives us cooling by refrigeration cycle, air conditioner distribute conditioned air to a specified areaand give comfortable environment

Air conditioning is the process of conditioning air, removing humidity, improves air movements, cleaning and ventilation. This system is referred as heating ventilation and air conditioning (HVAC).

Refrigerator is another house hold machine which uses electrical/mechanical/chemical way cool an insulated small area. It transfers heat from the insulated area to outside the room. This process keeps the insulated area cool and we can use refrigerator to store food.

Lower temperature inside the fridge helps to keep food items for long time without spoil. Lower temperature helps to decrease reproduction rate of bacteria.

How an air conditioner works

We are familiar with 2 cooling devices one is AC and another is refrigerator both devices have same mechanism for cooling. Refrigerator cools a certain area which is insulated but air conditioner used to cool a large area. Both use chemicals to transfer heat from the house to outside air.

An Ac contains mainly three parts

1. Compressor

2. Condenser

3. Evaporator

Commonly Evaporator is located inside the room and compressor and condenser outside the air portion.

Air conditioning mechanism transfers gas to liquid and wise versa that’s helps it to remove heat air inside the house to outside. Working fluid in the compressor arrives as a low pressure gas and compressor make this low pressure gas to high pressure gas by compressing. This process produce large amount of heat. We can see a fan is attached with ac is to remove this temperature.

This high pressure gas enters into condenser and converts this high pressure gas into cool liquid. This liquid then passes though Evaporator into the room makes it cool. Heat air from room absorbs this cool liquid gas. After combining with high temperature room air condensed liquid gas converts into cool air.

Evaporator has fins which are mainly used to transfer this condensed liquid air to all over the room. Evaporator also has fans which works together to complete the tasks.

This evaporated gas finally come back to compressor and the cycle start all over

How a refrigerator works

In the case of refrigerator this process all takes place inside the fridge. Similar to air conditioner refrigerator have compressor, condenser and evaporator. Compressor changes air into high pressure gas and pass to condenser which cools the gas and changes to liquid gas then pass to evaporator which then evaporate the liquid gas to refrigerator and cools it. This air finally comes back to compressor and the cycle continues.

Uses of Air conditioner

Most common commercial use of air conditioner for conditioning commercial, room, indoor, industrial spaces, institutional buildings low space residential buildings. Etc

Other uses of air conditioner is also important

1.  in laboratories to find precise measurements in different temperature.

2. To study effect of temperature in living organisms

3. Textile and other manufacturing industries depend up on moisturized and conditioned air.

4. Steel manufacturing industry need dry air

5. Pharmaceutical industry need refrigerator to keep medicines and bacteria.

6. Photographic industry need air conditioning.

7. Farm animals and some zoo animals need conditioned air
