By understanding the refrigeration cycle so you can better troubleshoot and repair your fridge.[/summary] [summary_image|2955974] == How Does a Refrigerator Work? == A refrigerator works by using the vapor compression refrigeration cycle to remove heat from the interior of the appliance and transfer it to the surrounding environment. By effectively moving heat energy to the outside, the transfer cools the space inside. This process relies on the principles of thermodynamics and the properties of refrigerants to efficiently transfer heat in the system. == Component Diagrams == To help you make the step from the theoretical diagrams you will see to the refrigerator in your home, here are three diagrams of common refrigerator layouts.

You may find other layouts with dual evaporators especially side-by-side units.] == The Main Components of the Refrigeration Cycle == The refrigeration cycle involves four main components: the ''compressor'', the ''condenser'', the ''expansion valve or capillary'', and the ''evaporator'', all of which manipulate the pressure and phase (liquid or gas) of the refrigerant to absorb heat inside the compartment and release it outside the compartment. You can see these components in the diagrams above as they are located in three different refrigerators. They all use the same principles of operation explained below. === Refrigeration Cycle Diagram === [image|2955957|size=medium] === Compression === * The cycle begins with the compressor, which is essentially a pump driven by an electric motor. * The compressor's primary function is to compress the refrigerant gas, increasing its temperature and pressure. === Heat Dissipation === * The hot, high-pressure refrigerant gas exits the compressor and enters the condenser, a series of coils or tubes located at the back or underneath the refrigerator. * The gas releases heat to the surrounding environment (air), as the condenser fan blows air over the condenser tubes. * As the refrigerant gas cools in the condenser, it condenses, releasing more heat, and becoming a warm liquid, still under high pressure. === Expansion === * The high-pressure warm liquid refrigerant flows through a small diameter tube called a capillary tube that restricts the flow of liquid refrigerant. * This capillary causes the refrigerant liquid to lose pressure as it flows through it. * At the end of the capillary where it joins the evaporator, the now lower pressure in the evaporator allows the liquid refrigerant to expand and a small amount turns back into a vapor. * In order to become a vapor this small portion of the liquid absorbs heat from the warm refrigerant liquid, cooling the remaining liquid and becoming a low-temperature mixture of cold low-pressure liquid with a bit of gas. * ***Our diagram shows an expansion valve, the capillary does the same basic thing.*** === Cooling the Interior === * The cold, low-pressure refrigerant liquid and gas mixture flows through the evaporator, a set of coils or tubes located inside the refrigerator or freezer compartment. * The refrigerant liquid in the mixture vaporizes and to do so it absorbs heat from the air in the interior of the refrigerator, causing that air to cool. * The evaporator fan circulates the air inside the fridge, to allow it to pass by the cold evaporator, and cool the interior of the fridge. * This process of cooling the air continues until the desired temperature is reached. When the compressor is shut off, the flow of refrigerant stops, and the cooling stops. === Return to the Compressor === * The refrigerant, now warmed and transformed fully into a low-pressure, cool gas, returns to the compressor, where the cycle begins anew. === Temperature Control === * The refrigerator's temperature is maintained through a feedback control system involving temperature sensors and thermostats. * When the temperature inside the compartments rises above a set point, the thermostat signals the compressor to start the refrigeration cycle. * Once the desired temperature is reached, the thermostat signals the compressor to stop. When the compressor stops the cooling stops. == A Helpful Analogy == You can think of the refrigerant as a sponge for heat. A tightly gripped (i.e. compressed) sponge is plunged into a water-filled basin (the inside of the refrigerator). Releasing the sponge (reducing the pressure/expansion) allows it to absorb water (heat) from the basin. The soaked sponge is removed from the basin and squeezed (compression), causing the water to pour out into the kitchen. Repeat this process many times and you can remove much of the water from the original basin. Another comparison is the human body's cooling mechanism—sweat. Your body uses a phase change (evaporating water) to cool you off. Your body supplies the heat to make that happen which cools you off. When the air is dry evaporation takes place rapidly. and the cooling effect is high. When the air is humid, the sweat doesn't evaporate as well and you feel hot and sweaty. == More on Refrigerants == Good refrigerants have a low boiling point to be able to absorb heat by boiling even in chilly conditions like the inside of a fridge or freezer. They also have a high critical point, which determines the highest temperature they can exist as a liquid and a gas, and a high latent heat, which means they can absorb (or release) more heat during phase changes (like from a liquid to a gas). Finally, they rely on low viscosity to be able to flow throughout the system with minimal flow loss (except in the capillary tube), so the pressure can be manipulated to facilitate heat transfer and high density (to maximize the amount of energy stored in the compound, to increase its effectiveness further). Refrigerants are chosen for their chemical structures that possess these properties, and others like low toxicity and cost effectiveness. == ''Too Long; Didn't Read'' == A refrigerator works based on the principles of thermodynamics, pumping a refrigerant through a cycle of tubes, which absorbs heat inside the fridge and dissipates it outside.

+
+# Hoe Werkt een Koelkast?
+
+Een koelkast werkt door middel van de dampcompressiekoelcyclus, die warmte uit het interieur van het apparaat verwijdert en naar de omgeving overbrengt. Door warmte effectief naar buiten te verplaatsen, koelt de ruimte binnenin af. Dit proces is gebaseerd op de principes van thermodynamica en de eigenschappen van koelmiddelen om warmte efficiënt over te dragen binnen het systeem.
+
+# Schema's van Koelkastindelingen
+
+Om de overgang van theoretische diagrammen naar de koelkast in jouw huis makkelijker te maken, vind je hier drie schema’s van gangbare koelkastindelingen. Klik op elk diagram om een vergrote weergave te zien.

+[image|3261737|size=large|caption=De Franse-deur koelkast, veel voorkomend bij luxere modellen; vaak met twee verdampers. Andere indelingen, vooral Side-by-Side modellen, kunnen ook dubbele verdampers hebben.]
+
+# De Belangrijkste Componenten van de Koelcyclus
+
+De koelcyclus bestaat uit vier hoofdcomponenten: de ''compressor'', de ''condensor'', het ''expansieventiel of capillair'' en de ''verdamper''. Elk van deze componenten beïnvloedt de druk en fase (vloeibaar of gasvormig) van het koelmiddel, zodat warmte binnenin wordt geabsorbeerd en naar buiten wordt afgevoerd. In de bovenstaande schema’s kun je deze componenten terugvinden in verschillende typen koelkasten. Ze werken allemaal volgens dezelfde principes die hieronder worden uitgelegd.
+
+# Diagram van de Koelcyclus
+
+!
+
+[image|2955957|size=medium]
+
+# Compressie
+
+* De cyclus begint bij de compressor, een pomp die wordt aangedreven door een elektromotor.
+* De compressor comprimeert het koelmiddelgas, waardoor de temperatuur en druk stijgen.
+
+# Warmteafgifte
+
+* Het hete, hogedrukgas verlaat de compressor en stroomt naar de condensor, een reeks spoelen of buizen aan de achterkant of onderkant van de koelkast.
+* De condensor voert warmte af naar de omgevingslucht, waarbij een ventilator lucht over de condensorbuizen blaast.
+* Terwijl het koelmiddel afkoelt, condenseert het en verandert het in een warme vloeistof onder hoge druk.
+
+# Expansie
+
+* De vloeibare koelmiddelstroom gaat door een capillair buisje dat de doorstroming beperkt.
+* Hierdoor verliest het koelmiddel druk terwijl het door de capillaire buis stroomt.
+* Bij de overgang naar de verdamper zet het koelmiddel gedeeltelijk uit en verdampt deels.
+* Dit verdampingsproces onttrekt warmte aan het resterende vloeibare koelmiddel, waardoor het mengsel van gas en vloeistof koud wordt.
+* ***Onze diagrammen tonen een expansieventiel, maar een capillair buisje werkt op een vergelijkbare manier.***
+
+# Het Koelen van het Interieur
+
+* Het koude, lage-drukmengsel van gas en vloeistof stroomt door de verdamper, een reeks spoelen binnen in de koelkast of vriezer.
+* Het koelmiddel verdampt volledig en absorbeert daarbij warmte uit de lucht in de koelkast, waardoor deze afkoelt.
+* De verdamperventilator circuleert de lucht in de koelkast, zodat deze langs de koude verdamper stroomt en de temperatuur verlaagt.
+* Dit proces gaat door totdat de gewenste temperatuur is bereikt, waarna de compressor wordt uitgeschakeld en het koelproces stopt.
+
+# Terugkeer naar de Compressor
+
+* Het koelmiddel, nu volledig in gasvorm en op lage druk, keert terug naar de compressor, waar de cyclus opnieuw begint.
+
+# Temperatuurregeling
+
+* De temperatuur van de koelkast wordt geregeld door een feedbacksysteem met sensoren en thermostaten.
+* Als de temperatuur boven een bepaalde drempel stijgt, schakelt de thermostaat de compressor in om de koelcyclus te starten.
+* Zodra de gewenste temperatuur is bereikt, schakelt de thermostaat de compressor uit en stopt het koelen.
+
+# Een Handige Analogie
+
+Je kunt het koelmiddel vergelijken met een spons voor warmte. Een samengeknepen (gecomprimeerde) spons wordt ondergedompeld in een waterbak (de binnenkant van de koelkast). Wanneer je de spons loslaat (expansie), neemt deze water (warmte) op uit de bak. Vervolgens knijp je de spons uit (compressie) en laat je het water eruit lopen. Door dit proces steeds te herhalen, kun je veel water uit de bak verwijderen.
+
+Een andere vergelijking is zweten bij mensen. Ons lichaam gebruikt een faseverandering (het verdampen van zweet) om af te koelen. De verdamping onttrekt warmte aan de huid, waardoor je afkoelt. Bij droge lucht verdampt zweet sneller en voelt de verkoeling sterker aan. Bij vochtige lucht verdampt zweet minder goed, waardoor je je warm en klam voelt.
+
+# Meer over Koelmiddelen
+
+Goede koelmiddelen hebben een laag kookpunt, zodat ze warmte kunnen opnemen door te verdampen, zelfs in een koude omgeving zoals een koelkast. Ze hebben ook een hoog kritisch punt (de hoogste temperatuur waarbij ze zowel in vloeibare als gasvormige toestand kunnen bestaan) en een hoge latente warmte (de hoeveelheid warmte die ze kunnen opnemen of afgeven bij een faseverandering). Verder hebben ze een lage viscositeit (om gemakkelijk door het systeem te kunnen stromen) en een hoge dichtheid (om zoveel mogelijk energie op te slaan). Daarnaast moeten ze veilig, kostenefficiënt en milieuvriendelijk zijn.
+
+# ''Te Lang; Niet Gelezen''
+
+Een koelkast werkt volgens de principes van thermodynamica door een koelmiddel door een cyclus van leidingen te pompen. Dit koelmiddel absorbeert warmte binnenin de koelkast en voert die af naar buiten.
