Consistent Temperature and Humidity Levels

Both cooling systems can maintain consistent temperatures and humidity levels, which are crucial for wine preservation. Two of the most common options are split system wine cooling units and through-the-wall wine cooling units. In this guide, we’ll compare their benefits and drawbacks to help you choose the best cooling unit for your wine cellar

Understanding Wine Cellar Cooling Systems

A wine cellar cooling unit is designed to maintain a consistent temperature between 50°F and 65°F, with humidity levels around 50-70%. Selecting the right cooling system depends on the size of your wine cellar, insulation quality, and installation preferences. These units can be installed in walls, ceilings, and floor spaces, offering flexible installation options.

What is a Split System Wine Cooling Unit?

Definition and Working Mechanism

A split system wine cooling unit consists of two components: an evaporator unit installed inside the wine cellar and a condensing unit placed outside or in a different room. These units are connected through refrigerant lines, making them more energy-efficient and quieter than self-contained alternatives.

Pros of Split System Wine Cooling Units

• Quiet operation – The condenser is located outside the wine cellar, reducing noise inside.
• More efficient cooling – Ideal for larger wine rooms and ensures stable temperature control. Compared to ductless wine cooling systems, split systems offer superior noise reduction and efficiency.
• Flexible installation – Can be adapted to different wine storage layouts.

Cons of Split System Wine Cooling Units

• Higher installation cost – Requires professional installation.
• More maintenance – Regular servicing is needed to ensure efficiency.
• Requires additional space – The condenser must be placed in a well-ventilated area.

Best Use Cases for Split Systems

A split system wine cooling unit is the best cooling unit for a wine cellar that is large, requires precise climate control, and needs a quiet, efficient cooling solution.

What is a Through-the-Wall Wine Cooling Unit?

Definition and Working Mechanism

A through-the-wall wine cooling unit is a self-contained system installed directly through a wine cellar wall, venting warm air into an adjacent room. This type of through wall cooling unit can be placed on an exterior wall for outdoor ventilation or ducted for interior placement, highlighting its flexibility and benefits in wine storage environments. These units can be mounted between the studs of a wall, emphasizing their ease of installation and improved ventilation.

Pros of Through-the-Wall Wine Cooling Units

• Easy installation – Does not require professional expertise. As a result, the installation process is streamlined and does not need a licensed HVAC technician. Self-contained cooling systems are convenient, compact solutions for wine storage that house all necessary components within a single unit, simplifying installation.
• Affordable cooling solution – Costs less than a split system wine cooling unit
• Compact and self-contained – Ideal for small wine rooms or compact wine cellars

Cons of Through-the-Wall Wine Cooling Units

• Noisier operation – Since the entire unit is inside the wine cellar, it generates more noise.
• Limited cooling capacity – Best for smaller wine storage spaces.
• Requires proper ventilation – The room adjacent to the wine cellar must dissipate heat.

Best Use Cases for Through-the-Wall Units

A through-the-wall wine cooling unit is best for small to medium-sized wine cellars, offering a cost-effective, easy-to-install cooling system.
