REFRIGERATOR:
The low temperature of the fridge makes the reproduction rate of bacteria work. Due to which the food items deteriorate less.
The refrigerator keeps the temperature slightly higher than the freezing point.
A temperature of 3 to 5 ° C is required to store food.
Information about freeze:
The device which maintains a temperature below freezing point is called freezer. More levels run on the refrigerator vapor-compression refrigeration system.
Domestic refrigerators come in many types of size range. The smallest of which is 4 liters. And comes with a capacity of up to 600 liters or more.
When buying Fridge, it is seen how much capacity it has in liters. The more liters you can store the more food.
In a modern fridge, you can keep your food fresh for long days and due to this, food can be stored in bulk and can be used later.
Because buying food in bulk saves money.
History of refrigerator:
When the refrigerator was not even invented, ice houses were used.
Artificial refrigeration began when Scottish professor William Cullen built a small refrigerating machine in 1755.
He created a vacuum in a container of (Cullen) Diethyl ether with a pump and boil it and absorb heat from the air surrounding it.
With the help of this experiment, he was able to produce small amounts of ice. But at that time there was no practical use of it.
Who invented refrigerator in Hindi
In 1805, American inventor Oliver Evans described the closed vapour-compression refrigeration cycle for ice production.
In 1820, British scientist Michael Faraday liquefied ammonia and other gas with high pressures and low temperatures.
In 1834, Jacob Perkins built the first vapor-compression refrigeration system to run a refrigerator.
This device could run continuously.
In 1842, American physician, John Gorrie created the working prototype but proved to be a failure in the market.
The first commercial ice-making machine was invented in 1854.
How does the refrigerator work.refrigerator working, information about freeze.com
Before understanding how this works, you have to understand the refrigeration cycle.
Currently every refrigerator uses a vapour-compression refrigeration system (VCRS).
It uses refrigerant. And it is used in the air conditioning of buildings and automobiles.
Vapor-compression refrigeration cycle
Liquid refrigerant is circulated as a medium. Which absorbs the heat from the space to be cooled and leaves the heat elsewhere.
VCRS has 4 main components.
compressor
condenser
thermal expansion valve
evaporator
