A Refrigerator has been the most useful and essential appliance for the household. We cannot even store our food without a refrigerator at our home. To operate and use a refrigerator efficiently, you must know how does a refrigerator works<\/strong>.<\/p>\n\n\n\n\n\n\n\n

<\/span>On Which Principle does a Refrigerator Work?<\/strong><\/span><\/h2>\n\n\n\n

The working principle of a refrigerator is based on vapor compression refrigeration cycle<\/strong>. It involves the removal of heat from the refrigerated space to the surrounding. The refrigeration cycle involves four components to work-<\/p>\n\n\n\n

  1. Compressor<\/strong><\/li>
  2. Condenser<\/strong><\/li>
  3. Expansion valve<\/strong><\/li>
  4. Evaporator<\/strong><\/li><\/ol>\n\n\n\n

    A refrigerator works in the following step-by-step process:<\/p>\n\n\n\n

    Step-1:<\/strong> The working process starts with the compressor. In this cycle, a circulating fluid, called refrigerant<\/a>, enters the compressor in the vapor state. Inside it, the refrigerant gets superheated.<\/p>\n\n\n\n

    Step-2:<\/strong> The superheated vapor travels through the condenser and dissipates the superheat outside the refrigerator. So, the room you keep in the refrigerator gets heated, and when the vapor leaves the condenser, it becomes liquid.<\/p>\n<\/div>\n\n\n\n

    \n

    Step-3:<\/strong> Next, the liquid refrigerant passes through an expansion valve. Here the pressure of the refrigerant decreases.<\/p>\n\n\n\n

    Step-4:<\/strong> Ultimately, it passes through the evaporator, where the cold refrigerant cools the warm air down. For this reason, the refrigerator chamber gets cold.<\/p>\n\n\n\n

    When the refrigerant leaves the evaporator, it gets to the vapor state again, and the vapor then passes through the compressor again and completes the cycle. This is how a refrigerator works. Home appliances like air conditioners also work on the same refrigeration cycle.<\/p>\n\n\n\n

    <\/span>Components of refrigeration cycle – detailed explanation<\/strong><\/span><\/h2>\n\n\n\n

    A refrigerator has two storage compartments – One for items requiring refrigeration and other frozen items. These compartments are surrounded by a series of heat-exchanging pipes. These are hidden in the walls of the refrigerator. At the bottom, the compressor is placed. Read the following details of Parts of the Refrigerator and the Function of each one.<\/p>\n\n\n\n

    <\/span>1. Compressor<\/strong><\/span><\/h3>\n\n\n\n

    A compressor <\/a>is a device that works mechanically to increase the pressure of a gas by reducing its volume. It is very similar to a motor. However, a motor cannot handle multiple phases of a substance together. Whereas, a compressor can handle liquid and gaseous phases together. <\/p>\n\n\n\n

    There are many types of compressors available- rotary, reciprocating, inverter, non-inverter, dual-inverter, etc. Nowadays, inverter compressors are emerging rapidly in the market as they are most efficient in minimizing power consumption.<\/p>\n\n\n\n

    <\/span>2. Condenser<\/strong><\/span><\/h3>\n\n\n\n

    The condenser is an essential component of a refrigerator as it condenses the heated refrigerant into liquid form. Without it, a fridge won’t work. It consists of coiled tubes made of copper with external fins and is located at the backside of the refrigerator. With such a condenser structure, the heat dissipation gets the most efficient.<\/p>\n\n\n\n

    <\/span>3. Expansion\/ Throttle valve<\/strong><\/span><\/h3>\n\n\n\n

    The Expansion valve controls the flow of refrigerant. The main objective of using such a valve is to decrease the pressure of the refrigerant before directing it to the evaporator. This is a small device that is very sensitive to the change in temperature of the refrigerant.<\/p>\n\n\n\n

    <\/span>4. Evaporator<\/strong><\/span><\/h3>\n\n\n\n

    A refrigerator cools because the heat inside the fridge gets transferred to the surroundings. The evaporator works precisely for this cause, and it consists of finned tubes with high thermal conductivity to maximize heat transfer. A fan blows out the heated air outside, and the refrigerant turns into vapor and flows towards the compressor.<\/p>\n\n\n\n
