Your wine collection needs to be kept in the ideal humidity and temperature by an efficient wine cellar cooling system. In this article, learn the basic mechanism of a wine cellar cooling unit.
THE CYCLE The compressor is where the cycle of refrigeration starts. There, a cool, low pressure refrigerant from the evaporator is compressed into a hot, high pressure refrigerant. Then this refrigerant is forced into the condenser where it turns to liquid. The refrigerant turns liquid when heat is taken out of it. The condenser removes heat from the refrigerant either by moving air across the coil or through another medium. The liquid refrigerant moves through the cooling system and into the metering device where the pressure is dropped and the refrigerant’s temperature is subsequently dropped. As this low pressure, low temperature liquid moves through the evaporator, it absorbs heat out of the warmer air and the cooler air is returned back to the wine room. In this process, the refrigerant turns from liquid back to a cool, low pressure gas and returns back to the compressor. The cycle goes on.
THE PRIMARY COMPONENTS 1. The compressor-the part responsible for pumping the refrigerant from a low pressure level to a high pressure level. Using a piston driven by a motor, the compressor increases the pressure on the hot refrigerant. There are two parts of the compressor. The first part is the suction valve which sucks the refrigerant from the evaporator. The second part is the discharge valve which maintains the high pressure needed to super heat the refrigerant.
2. Condenser. This component of your wine cellar refrigeration system is a tube, made from copper, where the super heated refrigerant circulates thus allowing the heat to be dissipated into the surrounding air. The condenser is responsible for receiving hot, high pressure refrigerant gas from the compressor and cooling it until it turns to its liquid state.
3. The refrigerant metering device-the refrigerant’s temperature needs to be low in order for it to effectively absorb heat. The refrigerant’s temperature lowers when its pressure is also low. The metering device is responsible for lowering the pressure of the refrigerant as it enters the evaporator, and it makes sure that the refrigerant flows properly throughout the cooling system.
4. Evaporator. This piece is usually made of a coil of copper and aluminum alloy tubing. It is in this component where the actual cooling takes place. The evaporator is a heat exchanger surface that transfers heat from the area to be cooled, inside your refrigerator or inside your wine cellar, into the refrigerant thus removing the heat from the area.
Refrigerant This substance functions similar to how alcohol works on your skin. If you pour alcohol on your skin, you will feel a certain coolness on that area of your skin. This is because as alcohol evaporates, it absorbs the heat on the surface of your skin thus making it cooler. The refrigerant functions similarly. The refrigerant is trapped inside the coils in the cooling system and as it makes its way through them, it evaporates inside the system and absorbs heat to create a cool temperature.
