Wine Cellar Cooling Units Refrigeration Systems Types
Wine Cellar Cooling Units & Refrigeration Systems – Types
Choosing the right type of cooling system is a critical step of any wine cellar construction project. It is vital to get this right before any design work is started.
You should consider the insulation, vapor barrier, wall and ceiling construction as well as the general way the room is sealed as part of the cooling system set-up.
The terms “cooling system” and “refrigeration system” are used interchangeably by most manufacturers. In either case the system must be able to maintain a constant temperature with minimal variance over time.
This is very unlike an HVAC air conditioning system. The equipment is different and the installation and construction methods are different.
How to Decide on the Best Wine Cellar Cooling Units & Systems
For the cooling system itself there are three main types of wine cellar refrigeration systems to choose from. In this article we will be purely discussing the cooling system types. Go here for details on insulation and room construction.
Each type of cooling system has its own unique benefits, pros, and cons. To help you understand the fundamental nature, benefits, and differences between these systems we have described and illustrated them below.
Remember, the objective is to maintain a constant, stable, and ideal environment in your custom wine cellar. Factors to balance in doing this are the location, the constraints, and the size of your wine cellar, along with the initial cost, the running costs and ease of maintenance of the system.
In each of the following types of systems, the size or capacity of the unit is also an important factor. Always have a specialist wine room cooling system technician size the needed system. Do not guess.
The Four Primary Wine Cellar Cooling System Types
- Self-contained through-the-wall Wine Cellar Cooling Units
- Ductless-Split Wine Cellar Refrigeration Systems
- Ducted Split air handler Wine Cellar Climate Control Systems
- Ducted Self-contained Air Handler Wine Cellar Climate Control Systems

Wine Cellar Project Features
These units are the simplest and generally the least expensive to install. They come in one piece, mount on the wall and vent through-the-wall.
When considering a self-contained wine cellar cooling unit, decide the best wall for placement and exhaust.
Many self-contained systems need to mount on an interior wall and exhaust the hot air and fan noise they create into an adjacent room. This room will need to be very well ventilated in order to accommodate the heat vented from the unit.
It is a common mistake with this type of wine cellar cooling unit to vent into a room that is too small or poorly ventilated.
A good rule of thumb is that the adjoining room should be at least the same size as your wine cellar and not typically exceed 80F degrees.
Rooms that are ideal for this heat and noise can be furnace rooms, mechanical rooms, unfinished portions of a basement, and possibly even a garage.
External Venting – Las Vegas Environment
Some self-contained wine cellar cooling units can be installed on an exterior wall. In this scenario, it is vital to be sure that the manufacturer offers a model that will operate effectively and efficiently in temperatures up to the highest possible temperature in your location. Needless to say, Las Vegas will test even the best equipment occasionally hitting temperatures in excess of 111°F
With only a few exceptions, self-contained systems are sealed by the manufacturer and will have to be removed from the wine cellar wall and shipped to the manufacturer for service or repair. This can be a pain and inconvenient at best.
Ductless-Split Wine Cellar Refrigeration Systems
An alternative, albeit more expensive option to consider, Ductless Split Wine Cellar Refrigeration Systems.
These require no venting into an adjoining room as the condenser of the unit, the part of the system that produces heat, can be located somewhere completely different.
The units are connected by a simple line set. A line set is a small copper tubing pair and electrical wiring. Therefore there is no bulky ducting to route and install.
These units can usually be serviced in situ and on-site making maintenance much more efficient and convenient.
These systems can be more expensive than through the wall systems as there is more to them.
However, there are many advantages to them that offset this cost. These include longer life expectancy, elimination of fan noise and heat exhaust to other rooms, straightforward installation, and the ability of the system to be serviced on site.
Ducted-split and Self-contained Air Handler Wine Cellar Climate Control Systems
A completely different type of cooling system is a Wine Cellar Cooling Air Handler.
With this type of system, there is no visible equipment in the wine cellar at all. Just a register and a return just like with the HVAC system in your home. The register pushes cold air into the room and the return takes warmer air to the cooling system.
The cooled air is simply ducted to and from the wine cellar. Therefore, in this type of system, there is ducting but no evaporator in the wine cellar at all.
There are two types of Air Handlers
- Ducted Split Air Handlers
- Ducted Self-contained Air Handlers
Ducted Split Air Handlers
With Split Air Handlers, the evaporator and the condenser are completely separate units.
The two units are intended to be located in different places, the evaporator inside and the condenser outside the building.
These are the quietest of the different types of refrigeration systems. The downside is that ducting has to be installed to and from the wine cellar. Depending upon the location of the wine cellar this may be easy or potentially very difficult.
As with Ductless Split Systems, these are usually very easy to maintain.
They have a longer life expectancy, elimination of fan noise, as well as no heat exhaust to other rooms. In addition, it has straightforward installation and the ability of the system to be serviced on site.
Ducted Self-contained Air Handlers
Self-Contained air handlers (not to be confused with Self-Contained Wine Cellar Cooling Units depicted in the first image) have both the evaporator and the condenser housed in a single unit.
The benefit of these systems is that they can be installed when there is no access to the outside of the building.
The downside is that they need to be installed in a larger well-ventilated room as all the warm air from the cellar will be vented into it.
How do Las Vegas Custom Wine Cellar help you to negotiate these options?
On request one of our experienced wine cellar designers will consult with you to understand your specific preferences and physical constraints. They will take those into account, first performing a heat load calculation to determine the proper BTU’s (sizing) needed for the wine cellar’s location.
Factors such as room size, R-factors, presence of glass, ambient conditions, and location of the wine cellar are all taken into account to provide you a much more specific set of options for the type of systems and the specific models that will best suit your conditions.
