  • Miten jääkaappi toimii?

    Oletko koskaan pohtinut, miten jääkaappi toimii? Katso video tai lue teksti alla niin tutustut kylmätekniikan perusteet, opit tuntemaan jääkaapin pääkomponentit ja saat tietää, mitä kylmäaineelle tapahtuu, kun se kulkee kylmäjärjestelmän läpi.

  • Mitä jääkaappi tekee?

    Jotta ruoka pysyy tuoreena eikä vaarallista bakteerikantaa pääse syntymään, pitää ympäröivän lämpötilan olla riittävän matala. Jääkaappi siirtää lämpöä sisältä ulos, jonka takia jääkaapin takana olevien metalliputkien lähellä tuntuu selvästi lämpimältä. Tästä opit lisää katsomalla videon.

     

  • What Are a Refrigerator's Main Components?

    1. Compressor

    The compressor is the "heart" of a refrigerator. It circulates the refrigerant throughout the system and adds pressure to the warm part of the circuit, and makes the refrigerant hot. It's similar to when you are pumping air into a bicycle tube - you can sense a heat increase in the pump while you compress the air.

    2. Condensor

    The condenser sits on the back of a refrigerator, and is likely quite dusty. Inside, the refrigerant is cooled down and condenses, meaning it turns from a gas back into a liquid.

    3. Evaporator

    The evaporator is located inside a refrigerator and is the part that makes the items in the refrigerator cold. As the refrigerant turns from a liquid into a gas through evaporation, it cools the area around it, producing the proper environment for storing
    food.

    4. Capillary Tube

    The capillary tube is a thin piece of tubing that serves as an expansion device. The liquid refrigerant is routed through the capillary tube and sprayed into the low-pressure environment of the evaporator.

    5. Thermostat

    The thermostat controls the cooling process by monitoring the temperature and then switching the compressor on and off. When the sensor senses that it's cold enough inside a refrigerator, it turns off the compressor. If it senses too much heat, it switches the compressor on and begins the cooling process again.
