As the leading supplier in climate-controlled wine cabinets with over 30 years of experience in wine storage, we only ever recommend considering wine cabinets equipped with compressor systems, especially given Australia&#;s extreme climate. This applies to both cellaring and serving cabinets.
The main reason for this is that compressors are much more capable and efficient at maintaining stable temperature even when external temperatures fluctuate. This is crucial for your wine because stable temperature is the most important factor in wine storage.
However, both systems are available on the market and there are some exceptions to the rule, so we have laid out below for you the main pros and cons of each system to help you can make an informed choice.
NOTE: We&#;ve had this comparison checked and signed off by a third-party refrigeration engineer to ensure validity of all information outlined.
Wine storage cabinets are generally equipped with compressors (which use vapour compression to achieve desired temperatures) rather than with thermoelectric systems. The latter are more frequently found on &#;wine chillers&#; or &#;coolers&#;.
To achieve cooling, the compressor pumps a refrigerant gas through the refrigeration system, which is composed of many elements including evaporators and condensers. In a good setup, the compressor should be mounted on the body of the wine cabinet and secured by means of rubber shock pads that absorb vibrations. This is to avoid any transmission of vibrations to the wine. Internal fans are used in some cabinets to maintain uniform internal temperatures, while others use external fans to blow heat away from the compressor.
Compressors can be equipped with many different types of refrigerant gases, some of which are more energy-efficient than others, for example R600a which also has zero ozone-depleting properties.
Advantages:
&#; Consistent temperatures and better control of temperature
&#; Easily serviced by any competent refrigeration service engineer
&#; Modular and individual parts means replacement is possible if required
Disadvantages:
&#; Generally more expensive than thermoelectric systems, and are more labour-intensive to manufacture and install
With regard to performance however, there are no major disadvantages with compressor systems as they are a proven technology that has been around for about a hundred years. During this time compressors have continued to improve in terms of performance, quietness and energy-efficiency.
Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials. The device has two sides and when DC (direct current) flows through the device, it brings heat from one side to the other, so that one side gets cooler while the other side gets hotter. It is obviously the cooling side that is important in refrigeration. Fans are generally used to distribute the cool air throughout the cabinet.

&#; Peltier &#; no moving parts, fluid or refrigerants
&#; Cheaper to manufacture, and less labour-intensive to install
Disadvantages:
&#; Limited temperature pull-down capability
&#; Not effective outside its very limited operating ambient temperatures
&#; Generally only around 10-15% as efficient as the ideal refrigerator (Carnot cycle), compared to 40-60% achieved by conventional compression cycle systems (vapour compression)
&#; More costly to run as it is not as efficient as the vapour-compression systems (in terms of coefficient of performance)
Wine storage and preservation is about consistent temperatures and control at all times. Given the inefficiencies of the Peltier system, thermoelectric cooling is generally severely lacking in temperature pull-down capacity versus compressor cooling systems. This is a particularly important issue when you open the door of your wine cabinet to:
&#; load more wine into your cellar;
&#; view or organise your collection; or
&#; pick out bottles to open and drink,
because with a thermoelectric system the cabinet will likely remain out of its set temperature for considerable amounts of time, and this can result in adverse ageing of your wine due to the frequent temperature fluctuations.
All Vintec and Transtherm wine cabinets are equipped with high-quality and quiet compressor systems, which have been thoroughly tested to ensure they function well in Australian and New Zealand climates.
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?
