Question

Почему в холодильнике холодно? немного

Answer 1

Итак, холодильник устроен таким образом, что он не охлаждает воздух в камере, а забирает из него тепло и отдает его в окружающую среду. Обеспечивается это разницей давления в конденсаторе и испарителе холодильника. Хладагент идет от участка с высоким давлением, где он обращается в жидкость (конденсируется), к участку с низким давлением, где давление хладагента понижается и он превращается в пар (испаряется).

Answer 2

Why is it cold in the refrigerator?

The refrigerator is designed to keep food and beverages cold in order to slow down the growth of bacteria and other microorganisms that can cause food spoilage. The cold temperature helps to preserve the freshness and quality of the stored items.

The cooling process in a refrigerator involves several components working together. Here's a brief overview of how it works:

1. Refrigerant: The refrigerator uses a refrigerant, typically a gas or liquid, that has a low boiling point. This refrigerant circulates through the system and undergoes a phase change from a gas to a liquid and back to a gas.

2. Compressor: The compressor is responsible for compressing the refrigerant gas, which increases its pressure and temperature.

3. Condenser: The hot, high-pressure refrigerant gas then flows into the condenser, where it releases heat to the surrounding environment. This causes the refrigerant to condense into a high-pressure liquid.

4. Expansion Valve: The high-pressure liquid refrigerant then passes through an expansion valve, which reduces its pressure and temperature.

5. Evaporator: The low-pressure liquid refrigerant enters the evaporator, where it evaporates into a gas. This process absorbs heat from the inside of the refrigerator, causing the temperature to decrease.

6. Fan: A fan inside the refrigerator helps to circulate the cold air, ensuring that the entire space is cooled evenly.

By continuously cycling the refrigerant through these stages, the refrigerator maintains a cold temperature inside.

In summary, the refrigerator is cold because of the refrigeration cycle, which involves compressing and expanding a refrigerant to absorb heat from the inside and release it outside the refrigerator. This process helps to keep the stored items cold and prevent spoilage.
