What is the difference between Compressor Wine Coolers & Thermoelectric Wine Coolers?

Individuals who are fond of wine and have a keen interest in properly storing the bottles in order to age them, often empty a part of their cellars so they can have the wine bottles stored and aged. It might be sufficient to get your job done if you live in a perfect world, however, it causes trouble for a number of other people and is just not enough. There are ones who face issues like mold, variations of temperature, and different other such things that can become a reason for failure to the aging of the wine bottle in a proper way. At this point, it is now that numerous individuals begin taking a gander at different alternatives they may have available to them, and by and large, one of the best solutions to finding a great alternative is to buy a wine cooler. 


When it comes to the taste and aroma of the wine, lovers of wine exactly know that preserving the wine at the right temperature can help in making a great difference in their beloved beverages. And that is one of the biggest reasons why wine coolers have become widely popular. Not only do people have them for their homes but wine coolers are exchanged as a gift item as well.


With time passing there have been a number of wine coolers introduced. With so many of the wine coolers in the present times, it is pretty confusing for the lovers of wine to which one is suitable for them.


Other than the size of the bottles or the configuration, one of the primary things that people realize when on the lookout for a wine cooler is that there are apparently incalculable various sorts of wine coolers to browse and choose from. A large number of these come outfitted with highlights that can without a doubt prove to be useful, yet by the day's end, the greatest thing to see when looking for a wine cooler is its cooling technique. In most of the cases, you can hope to experience two unique kinds of wine coolers: those that use thermoelectric cooling and those which are based on the compressor.


As one would expect, both of these kinds of techniques of cooling have their own interesting working, benefits, cost, etc. Prior to plunging into which kind of wine cooler is appropriate and suitable for you, be that as it may, how about we pause for a minute to go over how each type functions, what are the advantages, or which one is suitable for your pocket?

What Are Compressor Wine Coolers?

Compressor wine coolers utilize refrigerants, similar to your standard cooler or refrigerator. They can get down to bring down temperatures (if keeping white wine at very cold), can deal with higher encompassing temperatures, and may last for about more than the other wine coolers. In any case, compressor wine coolers or compressor units can be heavier, louder, and stronger.


Compressor wine coolers consist of cooling equipment just as a refrigerator: a compressor, coil of a condenser, and a refrigerant, for example, HFC-134a (Tetrafluoroethane) in addition to an evaporator.


It begins when the compressor cooler starts and the refrigerant is compressed, changing it into a fluid and raising its temperature. The refrigerant at that point travels through the coil of the condenser, where it discharges its quantity of heat into the external air before it arrives at the extension valve. The extension valve is a little opening in the coil of a condenser the refrigerant needs to go through to arrive at the compressor once more. The small width or diameter of the valve makes an imbalance pressure that makes the refrigerant boil over and evaporates as it goes through. The refrigerant then goes through the remainder of the coil of the condenser, which is associated with the wine cooler. The refrigerant pulls the heat out of the internal portion of the wine cooler and afterward gets pulled once more into the compressor so the cycle can come into working once more.

What Are Thermostat Wine Coolers?

Thermoelectric wine coolers are less common than compressor coolers. That’s because they use a unique phenomenon known as the Peltier Effect, named after the 19th-century scientist who discovered it to stay cool. Basically, two different sheets of metal are connected. Then an electric current is passed through the sheets, and something weird happens: one sheet of metal starts getting cold, and the other sheet starts getting hot. This leads to a zero-vibration method of cooling.


In comparison, thermoelectric wine coolers are environmentally safe, since they do not have any material that is hazardous, fueling the cooling process. When an electric charge is sent through two joined pieces of metal creating a heat flux, that is transferred from one side of the device to the other. Making either side hot and cold.

Benefits of Each Type of Wine Cooler?

Be it a compressor wine cooler or a thermostat wine cooler each one has its own pros that an individual can enjoy in order to maximize their experience. Here are some of the advantages of each type that are majorly looked up to while buying the wine cooler.  

Benefits of Compressor Wine Cooler

  • Compressor Wine Coolers Can Get Much Colder Compared to Others

A number of wine coolers including the thermostat coolers do not cool when they are below 50 degrees Fahrenheit. This refers to the fact that you will fail to get your hands on the required serving temperature that is proper and can satisfy you for sparkling wines or champagne. Due to the effect of the Peltier device integrated into the thermostat, it is not suggested in places that get warmer than 80 degrees. This is on the grounds because the Peltier device is not competent of good heat flux and can only lower the temperature up to 20 degrees. The recommended temperature for the storage of the wine in your cooler is about 55 degrees Fahrenheit, therefore, if your house gets comfortable up to 72 degrees Fahrenheit you are good to go without having any troubles. However, once the thermostat starts to rise you might have a hard time while handling the maintenance of the temperature you target for.


On the other hand, if we talk about the compressor wine coolers they have the capacity to reach up to the temperatures in the 30s and as well does not have any problem reaching the coldest temperature possible no matter what time of the year it is.

  • Compressor Wine Coolers Have Less Operational Cost 

The utility bills are everyone’s major concern these days. Therefore, considering the operational cost of the wine coolers is important as well. However, only going with the specification comparison amongst the wine coolers can lead you to miss out on the bigger picture.


Not to forget, first of all, the thermostat wine coolers are constant operational coolers, whereas, the compressor wine coolers possess a cycle technique that keeps the cooler working on and off, as per the necessity required to handle the maintenance of the temperature inside. The continuously drawn power does not only mean higher billings, in fact, the utilization of the equipment on a constant basis as well refers to the fact that the parts of the equipment are likely to break down quickly and might demand the replacement, which becomes an add-on over the pockets.


Besides, the energy proficiency of a thermostat wine cooler is significantly influenced by surrounding temperatures. As depicted above, the thermostat wine cooling limit can be restricted. As the comparison between the room temperature and the wine cooler maximizes, so does the measure of power it needs to use to arrive at that temperature. Compressor units, however, work considerably more effective in the hot climate.

Benefits of Thermostat Wine Cooler

  • Thermostat Coolers Work Without Vibration and in The Silent Mode

Thermostat Coolers Work Without Vibration and in The Silent Mode

The thermostat coolers work with a system that does not have any parts in motion, hence thermostat wine coolers are known best for working silently. In fact, if the thermostat wine cooler is placed in the right way on a leveled, firm surface it won’t disturb you with any nose at all. In case of any obstruction in the fans, you might hear a faint hum kind of noise or in case the wine cooler loses the level. Other than that, the thermostat wine cooler operates without any obstruction no matter whatever the living environment is.


Additionally, the system without any moving parts means that there is almost mill vibration observed while the operation process of the thermostat wins cooler. It is also useful especially if you are the one aging bottle for the long term because the flavor of the wine also stays good as there is no constant shaking in the wine cooler that can disturb the sediments in the bottle. 

  • Thermostat Wine Coolers Are Safe for The Environment

Wine coolers that consist of cooling units using the vapor compression refrigeration rely on the coolant that is based on the chemical in order to function as a heat sink and carry the heat from one place to another place. In the initial days of refrigeration technology, ammonia was used in the refrigerators however the substance was very toxic for humans. After that Freon was introduced, which was chlorofluorocarbon which turned out to affect the atmosphere of Earth by depleting the ozone layer. In this span of time that goes around two decades, technology has advanced exponentially and science has paved its way massively into the manufacturing of refrigerants’ substitutes. Whereas, the ones that are in use currently are less destructive than the former ones. However, these wine coolers are still known for emitting greenhouse gases and are still a reason for global warming.


Moreover, refrigerants are a perilous waste that should be discarded appropriately. Disposing of an old fridge can prompt some serious negative significance for the wellbeing of the local climate as well as the wellbeing of humans if the refrigerant leaks into the water supply or the soil.


Thermostat wine coolers do not have any such harmful emissions or substances within them. The thermostat wine coolers do not have any dangerous components and are environmentally safer than any other device or equipment. When you are thinking of disposing of a thermostat wine cooler you do not have to stress out as they are competent to get recycled without the worry of the risky substances.  

How Does Compressor Wine Coolers Work?

The vast majority are under the feeling that wine coolers work similarly to refrigerators in the old times or just how traditional refrigerators work, and in regards to units that are dependent on a compressor, this is for real. Basically, compressor wine coolers utilize what is known as a vapor pressure cycle to eliminate heat from the bureau, a similar way an air conditioner system reduces heat in a home.


This framework usually contains four fundamental parts: the condenser, the evaporator, the compressor, and the extending valve. The responsibility of a compressor is to compress the gas, while the condenser emanates heat outside into the environment. When the refrigerant hits the extension valve, its pressing factor is decreased, which transforms it into fluid form. At long last, the evaporator assimilates heat from the air, bringing about the cold air that is utilized to appropriately cool your wine.


It might sound confounding and intricate, however, there is a decent possibility that you have in case one more piece of equipment in your home that uses the same type of innovation. Some wine coolers likewise come outfitted with fans, through which the air is circulated and lets the used for the cooling purpose as well. While the technology has remained similar for a long time, makers of more advanced and modern wine coolers have sorted out approaches to reach the excellence of it, prompting more energy-effective items with better functionality.

How Does Thermostat Wine Coolers Work?

The thermostat wine coolers are not only efficient but quiet as well, which makes them ideal for spaces that are small and compact. The thermostat wine coolers are good if you are looking for a wine cooler for short-term use, and protect your wine as well.


A thermostat wine cooler contains a cooling hub consisting of a clay tile that has electrical flow gone through it. As the electrical flow is gone through the cooling hub the outside of the tile will warm up and the opposite side (the side looking into the cooler) will chill off. Normally, a thermoelectric wine cooler will contain little fans inside the unit which help to uniformly disperse the cool temperatures being made by the hub all through the inside of the unit. With thermoelectric wine coolers, a completely unique sort of innovation is used to keep the wines at the correct temperature. These units work dependent on two bits of metal that are combined, with each side being made of various materials. Basically, one side of the joined metal gets hot, while another gets cold as an electric flow is sent through them. The hot side is essentially a heat sink, permitting heat to go through and disperse all alone.


These gadgets are dependent on what is known as the Peltier Effect, and keeping in mind that there are no moving parts included, therefore the fans inside and out are normally used to help increment airflow, just as ventilation.


While getting a thermostat wine cooler you should know that there are some limitations in the wine coolers that are important for the effectiveness of a thermostat wine cooler.

  • The thermostat wine coolers do not work well when they are very hot. The thermostat wine coolers are not capable of producing cold air. In fact, while operating or functioning what it does is remove the heat from the inside of the compartment that is cooler. Therefore, when the temperature is very hot that is over 80 degrees Fahrenheit it will be problematic to remove the heat that can be enough to keep the temperature that is ideal for the wine storage.

  • The thermostat wine coolers do not get cool as much as the compressor wine coolers do. On average, the thermostat wine coolers do not cool below 50 degrees Fahrenheit. However, you might find some of them that can go below as much as 44 degrees Fahrenheit.

  • The thermostat wine coolers are also unable to operate when they are very cold. As there is no means of adding the heat into the wine cooler, therefore, as soon as the temperature of the surrounding drops to 50 degrees Fahrenheit, the interior temperature also drops. This drop in the temperature affects the conditions of storing your wine.

The Cost of a Wine Cooler ?

Cost is one of the significant components while you are shortlisting a suitable wine cooler for you. There are a number of wine coolers available in the market with different price ranges. The wine coolers can cost you between 50 dollars to 8000 dollars.


There are industrial wine coolers that are categorized in the higher end, it creates an environment like a cellar that can keep up to hundreds of wine bottles. Whereas, at the lower end the wine coolers compromise home-use appliances that can put up about six bottles.


Moreover, further there comes more differences between compressor wine coolers and thermostat wine coolers. The built-in and freestanding model as well makes an effect on affordability. 

Cost of A Compressor Wine Cooler ?

The compressor wine coolers are known for utilizing similar traditional refrigeration technology and innovation and are proficient in handling the wine bottles at a consistent temperature.


Units of compressor wine coolers serve exceptionally well with keeping your wine bottles in a secure and safe environment paying little heed to where you live, yet they will in general be somewhat costlier than their thermostat wine coolers.


Compressor wine coolers are available in a wide range, with limits that go from 4 to more than a hundred wine bottles. The most well-known compressor wine coolers for home use have limits somewhere between 8 to 50 bottles and on average, you can hope to spend around 325 dollars for your unit.


In detail, units with a limit of up to 8 bottles once in a while cost more than 200 dollars. Units with limits of up to 50 bottles don't cross the price limit of 500 dollars, however, costs can differ for bigger units. 

Cost of A Thermostat Wine Cooler ?

Thermostat wine coolers accompany their own pros and cons. On the fortunate side, they are less noisy and have a low degree of vibration which does not disturb the sediments of a wine bottle ruining the taste of it. They likewise save more energy and are greener. Thermoelectric wine coolers will in general have the best costs available in the market. Assuming you live in a cool environment zone, such a unit could be ideal for you.


On average, a thermostat wine cooler unit may cost you around 170 dollars and it is very simple to discover deals on-going on the products. An 18 bottle unit, for example, cost under 120 dollars however you will need to agree to a temperature zone. However, 18 bottle dual- zone coolers ordinarily cost under or around 200 dollars, which is still an extraordinary deal.


All things considered, bigger units with a limit between the range of 30 and 40 wine bottles can cost you around 375 dollars. Tracking down a thermostat unit with a limit of more than 36 containers is not common, because of the technology of cooling that performs better on the units which are small.

Bottom Line?

To figure out which wine cooler is suitable for you, you need to see what functions do you want in your wine coolers, the storage you need it for, which as well determines the use of the wine cooler.
