WHAT IS THE DIFFERENCE BETWEEN THERMOELECTRIC AND COMPRESSOR-BASED WINE REFRIGERATORS?

By October 6, 2020 January 12th, 2021 No Comments

The information below shows a comparison of the 2 different kinds of wine refrigerators. One kind is not necessarily better than the other. Your personal preference, budget, and the needs of your collection will be important factors that help you choose which kind of cooler is best for you.

The best metaphor would be to say if you are in your car with the air conditioner on, it’s cooling like a compressor. If you use the fan without the coolant, that is just the fan. Thermoelectric is quieter, and the compressor pulls down the temperature more efficiently.

DEFINING COMPRESSOR WINE COOLERS AND THERMOELECTRIC WINE COOLERS

Compressor Wine Cooler

This type of wine cooler operates similarly to a standard refrigerator. Air is compressed and then released to reduce the temperature of the interior. This process is known as the “vapor compression cycle”. This process helps to reduce the temperature significantly. The compressor wine cooler contains the refrigeration chambers in which a compressor is used to compress refrigerant molecules electronically. This increases the temperature of the particles. The particles are then released suddenly which in turn decreases the temperature of the air. This cold air is blown through the interior of the cooler using a small fan. Heat is expelled at the back of the unit. This makes it very important to follow all clearance guidelines to ensure the unit functions properly. As soon as the internal temperature begins to rise, the compressor kicks back on and works to cool to the preset temperature. Once the desired temperature has been reached, the compressor will turn off to prevent freezing the contents of the refrigerator.

Placing Your Compressor Wine Cooler
You may place a compressor wine cooler inside your home or office. You must make sure you are following all clearance guidelines to ensure the unit is able to exhaust. You should also ensure that you are placing the unit in a space that can hold its weight when loaded with wine.

Efficiency
The mechanism inside the compressor wine refrigerator allows it to maintain a wide range of temperatures irrespective of the ambient temperature. Compressor technology maintains the temperature quickly by alternating between on and off as needed.

PROS & CONS of a COMPRESSOR WINE COOLER

PROS:

1. Rapidly cools your wine.
2. No influence from the external environment.
3. Wide temperature range.
4. Optimal temperature can be set for both red or white wines independently.
5. Able to cool a large number of wine bottles.

CONS:

1. Compressors naturally emit more sound than a thermoelectric system.
2. Small vibrations may reduce the shelf life of your wine slightly
3. Uses more electricity and does use refrigerants
4. Uses heavier components which decreases its mobility

Thermoelectric Wine Coolers
Thermoelectric wine refrigerators use an electric current to create a temperature differential between the inside of the cooler and the external environment. The system utilizes a metal rod that is electrolyzed. The heated end faces the exterior in order to remove the heat from the interior of the wine cooler. The cooler end faces the interior. Similar to the compressor wine cooler, a small fan distributes the cool air throughout the inside. There is no alternating mechanism and no motors or compressors to create excessive noise or vibrations. These units are generally quiet but there may be a small amount of noise coming from the fan. Due to the temperature differential, freezing does not happen. The equipment will typically cool the inside of the cooler ten to twelve degrees colder than the ambient environment and will maintain this temperature automatically. The design was inspired by the Peltier Effect and is very efficient.

Placing Your Thermoelectric Wine Cooler
Because thermoelectric wine refrigerators are freestanding, you must follow the clearance guidelines and leave sufficient room on all four sides in order for the cooler to exhaust properly. If heat is not allowed to exhaust properly, the cooler will not operate efficiently. Moreover, due to the design of thermoelectric units, they should not be placed in a warm room.

Efficiency
Thermoelectric units are moderately efficient at cooling and dependent on the temperature of the external environment. In order to take advantage of the thermoelectric precise cooling ability, the cooler should be placed in a room with a mild temperature.

PROS & CONS of a THERMOELECTRIC WINE COOLER

PROS:

1. A good alternative for the preservation of wine.
2. Does not consume a lot of electricity.
3. Uses an environmentally friendly mechanism for cooling.
4. Does not use heavy equipment, lighter than compressor coolers, and easier to move.
5. Works best in rooms with a cooler temperature.

CONS:

1. Takes longer to cool the wine.
2. Interior temperature dependent on the external environment.
3. Temperature will remain the same unless the external environment cools or warms.
4. Smaller bottle capacity.
