when was refrigerator invented
Ask: when was refrigerator invented
Answer:
1834. American inventor Jacob Perkins, living in London at the time, built the world’s first working vapor-compression refrigeration system, using ether in a closed cycle. His prototype system worked and was the first step to modern refrigerators, but it didn’t succeed commercially.

Answer:
1834
Step-by-step explanation:
- A refrigerator (fridge) is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature.
- The first cooling systems for food involved ice. Artificial refrigeration began in the mid-1750s, and developed in the early 1800s. In 1834, the first working vapor-compression refrigeration system was built.
when does the cycle repeat on refrigerator?
Ask: when does the cycle repeat on refrigerator?
Answer:
The Vapor – Compression Cycle or otherwise known as Refrigeration Cycle.
The process that takes place inside the refrigerator is the “Refrigeration Cycle”
For us to be able to know better when and on what part of the refrigerator is the cycle repeating, let us first define terms:
- fluid refrigerant – cooling medium or the chemical inside the tubes of the system. Its main property should have a low boiling point, Sensitive to heat absorption, Pressure of evaporation is higher than atmospheric pressure and high evaporation rate.
- compressor – It is the heart of the system as it is keeps the refrigerant flowing.
- condenser coils – the black coils found at the back of the fridge. It cools and condenses the refrigerant.
- evaporator coils – the coils on the inside of the fridge.
- expansion device – devices used to control the refrigerant flow in a refrigeration system. They help to facilitate the change of higher pressure of liquid refrigerant in the condensing unit to lower pressure gas refrigerant in the evaporator.
- refrigeration cycle – Is a continuous cycle of vapor-compression of a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere.
The refrigeration cycle starts as it enters the Compressor.
(To imagine clearly the compressor, it is usually the black cylinder found at the bottom of the refrigerator. If you can’t see it that is the refrigerator component that you usually you hear whenever nearby a refrigerator.)
But since it is a cycle, basically it is just the starting point of the process.
- In the compressor the refrigerant is compressed and heats up. (Temperature is increasing, Pressure increases)
- The refrigerant then goes through the condenser coils where its temperature is being lowered as it passes through the coils with air fins. (air fins help in the cooling down of the fluid as it divides the surface area of the coils into smaller ones making it more efficient to release heat into the air) (Temperature decreases, Pressure decreases)
- The high pressure liquid refrigerant then flows through an expansion valve or capillary tubes to reduce its pressure, and regulate its flow into the evaporator. (In this point the refrigerant is cooler as heat is already released as it passed through the condenser coils, and becomes much cooler as it passes through the expansion valve. At this stage also in the refrigeration cycle, high pressure liquid refrigerant will flow down the liquid line, through a filter-drier that is designed to prevent contaminants from flowing through the system, and on to the metering device.) (Temperature decreases, Pressure decreases)
- In the evaporator, the low pressure liquid refrigerant absorbs heat from the fridge interior, changing to a low pressure gas in the process, and then flows on again to the compressor.
This process will continue throughout the lifespan of the refrigerator, this is also the cycle used in air conditioning systems or anything that requires the removal of heat in a certain space.

heat is absorbed by a refrigerant in a refrigerator when
Ask: heat is absorbed by a refrigerant in a refrigerator when it
Answer:
heat is absorbed by a refrigerant in a refrigerator when its changes from a liquid to a vapor.
Explanation:
The liquid refrigerant in the evaporator absorbs its latent heat of vaporization, and in the process changes from a liquid to a vapor. The gas refrigerant within the condenser rejects its latent heat of vaporization, thus changing from a gas to a liquid.
