          Nowadays, our country or even the whole world is experiencing hot weather,

because of our problem regarding with our ozone layer. We are experiencing “Global

Warming”. So for us to feel comfortable in our daily living, we invented appliances that

can help us. Then, “Refrigeration and Air Conditioning” was invented.

          Studying this kind of field is a great help for us. Most especially, the

“Refrigeration”, it helps us to store food, so that it won’t be spoiled easily, we can still

eat the food after few days if it will be stored inside. As well as the “Air Conditioner”, it

is also a great help for us, because we can feel coolness when we are inside the room

which is air conditioned. Especially, when we are experiencing a very hot weather, most

of us want to stay in a cold place.

          The researchers seek to find the answers of the following questions:

1.    What is Refrigeration and Air Conditioning?

2.    How can Refrigeration and Air Conditioning help us in our daily survival?

3.    What are the advantages of Refrigeration and Air Conditioning?

         

Refrigeration and Air Conditioning

          Refrigeration & Air Conditioning may refer to the general process of altering air

properties such as temperature, humidity, quality & velocity to achieve desired

conditions. It is a process in which work is done more heat from a low temperature to a

high temperature & typically also from one location to another.

Both industrial refrigeration & air conditioning are based on the same

mechanism: The cooling of substance. The refrigeration system made up of a

compressor, evaporator, fan, condenser & expansion device, is the heart of both

systems. Despite this, there are substantial differences between the systems, the

components used, the design methods and the structures they are used in, such as to

merit separate treatment.

          Food conservations involves various procedures, only one of which refrigeration,

which differ according to the duration.

·         Refrigeration if the food to be stores for a short time (0 C/+7 C)

·         Freezing, deep-freezing, freezing drying if the food is to be stored for long periods.

          For deep-freezing, the product must reach -18 C in less than 4 hours, while for

freezing the product can reach -18 C in more than 4 hours. During freeze drying, the

product is dried by the evaporation of its water content. Refrigeration slows down the

proliferation of bacteria in food.

          Air-conditioning use chemicals that easily convert from a gas to a liquid & back

again. This chemical is used to transfer heat from the air inside of a home to the

outside air. The machine has 3 main parts, the compressor, condenser & evaporator.

The compressor & condenser are usually located on the outside air portion of the air

conditioner. The evaporator is located on the inside of the house, sometimes as part of

a furnace.

Refrigeration & Air Conditioning can help us in our daily survival

          The Refrigeration & Air Conditioning is important for us, because in our lives, we

use the refrigerator & air conditioners in our home. We use refrigerator at home to

store our daily food, so we don’t have to keep trying to pressure the food on salt.

Refrigerators have been along for a longer period of time & each time, they’re finding a

better way to make people’s lifestyle easier. We also use air conditioners to give us

comfort & coolness.

Advantages of Refrigeration & Air Conditioning

          Homeowners can choose between evaporative coolers & refrigerated air

conditions. The latter is more commonly used because this device carries clear

advantages. While areas, such as deserts, suffer from dried-out air, other areas benefits

from dried-out air, including areas with humidity. Also, of course, the cooled air carries

its own benefits.

          Refrigeration:

·         The advantages of Refrigeration’s construction division focus on the design, manufacture, installation & commissioning of commercial & industrial refrigeration systems.

·         While our service management group provides & support to customers & their equipment. Both groups work closely together to ensure that appropriate resource are always available to satisfy customer requirements at every stage of their refrigeration equipment’s life cycle.

          Air conditioning:

·         It has its obvious advantages but there are times when it may be needed more than others. An example of this is: Office Buildings. The reasons for this are because:

1.    There are a lot more people in the office then there would be in a house.

2.    There are a lot of machines generating heat as well.

3.    A hot & stuffy office can make employers/employees irritable & less likely to work, so it is important to have a proper air conditioning system installed.

4.    It can be a lot more powerful than a small fan you plug in at the wall

5.    If you have a large open plan office it would be impossible to keep everyone cool with small fans or plug in units. However, having a proper air distribution of cool air which will keep everyone happy.

Conclusion

          The researchers concluded that Refrigeration & Air Conditioning really is

important in our daily living, especially nowadays. Refrigeration & Air Conditioning are

the same mechanism, the cooling of substance. There are a lot of advantages regarding

with this topic. One of which is that a refrigerator slows down the proliferation of

bacteria in food, so, food that are stored in refrigerator are not easily spoiled & air

conditioner is a great help especially in office buildings, because it gives comfort to the

employers/employees & it also lessens irritation among them.
