Manufacturers have started to apply thermoelectric cooling technology in small household appliances in recent years, though the scientific principles of thermoelectric cooling were discovered in the 19th century by a French scientist, Jean Peltier.
He found that if electric current flows through two different connected metal conductors a temperature difference occurs.
Coolers & Filters
The junctions of the metals were heated or cooled depending on the direction of electric current that passed through them.
In the cooling system of thermoelectric wine coolers consists of so-called thermocouples (also known as Peltier modules) are used.
These modules consist of pairs of dissimilar semiconductors between two ceramic plates. If electric current is applied to the modules one end heats up while the other end cools down. The temperature of the cold end of conductor pairs will quickly drop down the ambient temperature provided heat is driven away from the hot side. The generated temperature difference depends on the magnitude of current applied.
In short, thermoelectric cooling modules work as heat pumps driving heat from one surface to the other and generating cold temperature inside the appliance. The heat has to be effectively removed and dissipated for which fans are used in thermoelectric wine coolers.
So, after all this technical explanation let's find out what are the strengths of thermoelectric wine coolers. Are they better than compressor run wine refrigerators?
You know that the compressor in kitchen fridges can be rather noisy especially if it's an older model.
Noise caused by the running fridge compressor might not disturb you and it does not have any harmful effects on the food stored in the unit, but that's not the case if you keep wines in it.
Vibration disturbs the natural sedimentation of solid particles in wines modifying and spoiling the flavor and consistency of it in the long run.
Thermoelectric wine coolers, however operate without compressor and the only moving part that can cause noise is the fan for circulating the cold air within the cooler cabinet and driving out the generated heat. So, if you want a silent, vibration-free electric wine cooler than opt for a thermoelectric one.
Some say that compressor-operated wine coolers are more efficient in generating cool air but if you place and operate a thermoelectric wine cooler according to its manual than you will be satisfied with it.
One thing you have to especially pay attention to is the ambient temperature of the room where you are going to place the cooler. For proper operation and efficient cooling a thermoelectric cooler must not be placed in a room with ambient temperature higher than 77 °F (25 °C) otherwise the appliance won't be able to maintain the set temperature.
Since thermoelectric wine refrigerators don't contain cooling agents like CFC-s, HCFC-s - organic materials that were identified to be responsible for the thinning of ozone layer - they have less harmful impacts on the environment when they are disposed of at the end their life cycle.
Another environmental friendly feature of thermoelectric wine coolers is that they use less electricity during their operation.
Thermoelectric wine bottle coolers are also small, compact appliance so even those who live in tiny apartments can find space for a nice thermoelectric wine fridge. No need to worry about your wines going off during the hot summer.
