HOW DOES THE REFRIGERATION CYCLE WORK?

Refrigeration is an important aspect of both domestic and commercial food management. The creation of the first modern fridge in the late 1800's was an ushering of a great era in the food preservation and foodservice world. This has further been advanced by new technology which has seen a current production of more than 1 billion refrigerators around the world.Get more news about Condenser Expansion Machine,you can vist our website!

The one main reasons why refrigerators are used in businesses and at home is to keep food cold. Fridges are important because food stays fresh for longer, thus helping cut down wastage in both homes and businesses. They also help increase profits in businesses by maintaining the quality of food for a longer time and allowing chefs the time and opportunity to create their best foods.

More production of food which is, in normal circumstances, highly perishable has increased the need to have storage mechanisms that prevent wastage and unwanted loss. However, as much as refrigeration is an important part of our lives, one question remains, how does a refrigerator work and how does it maintain such cold temperatures for a long time?

The Refrigeration Cycle Components
A standard refrigerator will have mechanical elements that make it easy for it to achieve and maintain cold temperatures. They are the components that will maintain the refrigeration cycle. These components are highly specialised in order to provide the desired effects.

They include a compressor, condenser, expansion valve/metering or throttling device and an evaporator. Additionally, the fridge has to use a refrigerant, a substance that is used to provide the cooling effect. The refrigerant has to pass through all these components and in each, it is altered to achieve the required temperatures.
Compressor
Its work is to control the flow of the refrigerant by acting as a motor and a pump. This allows it to pressurise the refrigerant and reduce its volume.

There are five types of compressors used in both commercial and domestic refrigerators. They include reciprocating, rotary, screw, centrifugal and scroll. Of the five, the reciprocating compressor is the most commonly used in home and commercial kitchen refrigerators.

Condenser
The condenser works by condensing the refrigerant. The refrigerant entering the condenser is hot and pressurised. The condenser then cools the refrigerant by converting it into a liquid state.

There are three types of condensers.

Air-cooled. you will find this in small refrigerators such as the ones used at home. They are ideal when the refrigerant quantity is small. The air-cooled condenser is also called coil condenser because it comes with aluminium or copper coils at the back of the fridge. The coils increase the surface area for cooling the refrigerant.

Air-cooled condensers are further divided into two. The natural convection condenser which uses the natural flow of air to cool the refrigerant and the forced convection condenser which uses a fan to draw in cold air.
