What Home Owners must know about the inside of Refrigeration and Air System


We all enjoy the serenity of chilling atmosphere in our bedrooms when it’s hot scorching heat outside. But, while we all enjoy this magic of thermal comfort, not all of us are aware of the mechanism that feels such a blessing. This article will enlighten you about the inside of the cooling effect, whether it’s your Refrigerator or Air Conditioner.

The Inside of a Cooling System




Starting with, the common myth about the Air Conditioners is that, they cool the air inside the room. This isn’t correct. In reality, the Air Conditioner absorbs the heat content from the room, leaving a cool soothing temperature inside. Now let’s get into the details.

When a liquid evaporates, it causes a cooling effect. This is the basis of the mechanism of cooling the air. To utilize this phenomenon, the company uses a refrigerant that evaporates at low temperatures. This refrigerant travels the conditioning system, whether it’s an Air Conditioner or a Refrigerator, to absorb the heat content from the air and transferring it outdoor.

Steps Involved in Cooling the System

Following are the steps involved in the cycle of cooling of air.

  1. Cold refrigerant flows through the evaporator coil. The fan carrying hot air blows over the coil. The refrigerant absorbs the heat content of the air, leaving a cool air behind which is blown into the room. After absorbing the heat, the refrigerant turns into a low pressure gas.
  2. The hot refrigerant travels to the compressor where its pressure is increased along with its temperature.
  3. The hot, high pressure refrigerant then moves to the condenser where it releases absorbed heat and turns back into liquid.
  4. The liquid refrigerant goes back to the expansion valve. From there, it goes on to repeat the cycle.

The most important part of the Air Conditioning unit, the condenser, is usually cooled by two methods; one or the other. If it’s for home application, the condenser is usually air-cooled. Such condensers are cooled by the surrounding air. On the other hand, large Air Conditioning units for commercial usage, require a cooling tanks to provide water for cooling the condenser.
