What is Refrigerator Refrigerator? Structure, function and principle of operation

Refrigerator shell is a part that is responsible for preventing snow from forming on the indoor unit, for the refrigerator to operate stably, smoothly and effectively. Invite you to learn what is the refrigerator shellfish? Structure, function and operating principle through the following article!

What is Refrigerator Refrigerator?

Concept

Cold clam (also known as snow relay) is a semiconductor plate placed in the middle of the indoor unit to notify the heating element when the indoor unit is frozen too much.

Structure and function

Cold oysters are composed of:

• Two thin steel foils: Hermetically sealed to prevent electric leakage, water and heat absorption on one side and then discharge through the other surface.
• Two contacts: Always open and closed only when the ambient temperature is negative.

The cold clamshell has the function of ensuring that the thermostat defrosts when the refrigerator is covered by snow to limit the heating of the indoor unit when it is not needed, thereby ensuring a cold temperature for the refrigerator and helping the defrost unit also as the appliances in the cabinet operate most efficiently.

Working principle

When the temperature of the refrigerator turns to a certain negative level or the indoor unit is covered with too much snow, the cold cock will activate to heat the resistor bar to melt this layer of snow, helping the cold air to circulate evenly in the refrigerator. When the snow layer has melted, the cold oysters will automatically turn off.

How to check if cold oysters are still good?

Use a meter

To check if cold oysters are still good with a meter, you need to expose cold oysters to a negative cold temperature below the allowable level specified on the cabinet body. At that time, if the meter reads, it means that the cold oysters are still working well, otherwise, the cold oysters are broken.

Based on the operation of the links in the refrigerator

With this test, you only need to check the components inside the refrigerator such as the defrost system, if they are in good working order, it means your cold clams are still working well, otherwise, it means the refrigerator’s cold clams. already broken!

Some notes when replacing refrigerator shells that consumers need to know

When replacing broken cold oysters, you need to pay attention to the following issues:

• When the refrigerator shows the signs mentioned in the above items, please check and replace immediately if they are damaged to ensure stable operation or contact the service center or repair center. reputation to be tested offline!
• You should not arbitrarily disassemble the components inside the refrigerator to check because if you lack knowledge about the cabinet, you may accidentally affect the operation of other parts in the refrigerator.
• Replacing new cold oysters for the refrigerator is quite simple, but if you are not sure about your skills and knowledge, please contact a technical staff for a replacement!
• As a replacement, you need to choose genuine components, of the same brand as the old cold clam, to ensure stable operation of the cabinet along with the old components.
