How does a Tower Crane Work

Refrigerator

In this modern age, everyone is busy doing their work so they don’t have enough time to cook a fresh meal so they want to store their food for a long time but here a problem raised if they store their food at room temperature then food will not good for health because it will lose freshness and quality. Refrigeration maintains the temperature below room temperature so it will preserve the freshness, quality, and food safe for long the long time slot. When you want to eat your stored food then takeout food from Refrigeration and enjoy your food that is why refrigeration has become a very important part of any home. It works based on simple scientific principles.

How does a refrigerator work

What is Refrigerator:

Mainly cools food stored inside the refrigerator, it removes heat from the food compartment and leaves it outside.

Structure of Refrigerator:

The refrigerator needs four elements to keep food cool.

·        Evaporator.

·        Compressor.

·        Condenser.

·        Expansion valve.

Structure of Refrigerator

Evaporator:

The evaporator is located on the refrigerator's top.In which the cooling refrigerant cools the food by reducing the heat.

Compressor:

Compressor increases the pressure and temperature of vapors.

Condenser:

The condenser converts the hot vapor into a liquid and is on the back side of the refrigerator.

Expansion valve:

The expansion valve converts hot liquids into cold liquids and vapors.

Operation of Refrigerators:

Let's start with the process that takes place in the food compartment.

Operation of Refrigerators

Refrigerant is basically a cold mixture of vapor and liquid. These cold vapors flow into the pipe system. The refrigerant removes heat from the food compartment due to the difference in temperature.
The refrigerant then heats up and evaporates completely, causing it to dissipate more heat. Vapors from the food compartment flow into the compressor, which compresses it and increases the temperature and vapor pressure.

flow into the compressor

The hot vapor is then transported to the condenser, where the vapor releases its heat into the atmosphere due to the temperature difference between the vapor and its surroundings.As the temperature of the vapor flowing in the pipe decreases it becomes a liquid.This partially cooled, hot liquid then enters the expansion valve.Here it accumulates and hence the pressure in the pipe coming into the expansion valve is high while the pressure in the pipe coming out is low.

As the liquid flows in the expansion valve its pressure suddenly drops and therefore the boiling point of the liquid decreases and it partially evaporates and cools down.As a result of evaporation and liquid, the cold mixture is taken back to the evaporator. Where food gets cold.
