A fridge is an appliance that is indispensable in every kitchen. There are many models to choose from – with various functions, with freezer or without it etc. Selection is very wide so each customer may find something that will suit him. Most people do not think how does this appliance work – we just put food inside of it. It is worthwhile to know basics of this appliance working.
What conditions should be inside of the refrigerator?
In refrigerator, we store food that most usually should be kept in low temperature and with correct humidity. The appliance should be able to lower temperature inside to 5 degrees, and some of them require even colder environment. If You own a refrigerator with a freezer, then foodstuff that need temperature kept below freezing point, then this is a perfect place to keep them. Freezing is a very efficient method of keeping many types of edibles safe.
Cooling process
Cooling inside of the refrigerator is accomplished by employing proper machines inside. The concept of cooling system is very simple –piping system on the back of the appliance is filled with cooling agent. It is compressed inside of the compressor, and then forced through evaporator on the back – which causes it to heat up. Afterwards, it passes to the inside of the appliance, where pipes are bigger, which causes a sudden pressure drop and therefore temperature reduction. This cold agent drains heat from all the surroundings. It is most usually placed inside of the freezer.
Refrigerator in home
In household refrigerators, most usually a compressor is employed. It is a machine that compresses cooling agent by a pump powered by an electric motor. It forces the agent to move inside of the piping. Compressor-based refrigerator is the most popular, since it is reliable, relatively cheap and maintenance free.
Thermostat – a vital part
Thermostat is an element, which plays a vital role. In case of temperature rise inside of the appliance, it switches on the compressor. When the temperature falls below safe level, it shuts it off. This simple mechanism regulates temperature inside, so the compressor does not have to work all the time therefore reducing energy consumption.
Proper insulation
Refrigerator is an appliance that must be properly insulated. Heat from the outside cannot enter – it would cause the compressor to immediately turn on to reduce temperature and consume more power.
Choosing a refrigerator
Why it is worth knowing how does a refrigerator work? It will be helpful when choosing one to buy. Knowledge of basic principles will allow us to choose a model to fit out needs. A very good solution would be a Kernau brand KBR 17122 built-in refrigerator. It is a construction that guarantee effective cooling of various foodstuffs. It is based on modern, but tried technologies, so it will work failure-free for years. It has a capacity of 250 liters, so it can fit much food inside.
