The wine cellar is the place for aging and storing wine in the bottle or wooden cask; the room insulation it’s a key factor to the efficiency of this place. Often people use as wine cellar a basement, a normal closet or storage room, or just not used room; to perform its functions and keep your best wines, a good wine cellar must have specific characteristics.
Main features of a wine cellar
The main features of a perfect cellar are:
- The total absence of light
- A stable temperature below 18 ° C
- Humidity stable between 60 and 80%
The certainty that a wine cellar has a temperature that is at least below 18°C and a humidity between 60 and 80% guarantees the biological and physico-chemical stability essential to properly maintain your wines, enhancing their quality over time. For “stability” we mean that the values of these features should not swing, and should be the most possible disconnected from weather, seasons and the outtdoor climatic situation. To achieve this goal, the wine cellar insulation is a fundamental aspect that should be evaluated before even thinking about the climate.
It is up to the owner make the most correct choices during the construction or renovation phases of the room that will become his wine cellar to ensure that, if he chooses to install an wine cellar conditioner, it can act efficiently and guarantee the best performance; the inclusion of a wine cellar conditioner inside an unsuitable environment (not properly isolated), can’t in itself be enough to ensure the stability of temperature and humidity values. For this reason you can’t only rely on the cellar floor area to choose the air conditioner, but you should always check the local conditions and the isolation of the cellar, based on the values to be achieved.
How to obtain a good insulation of the wine cellar
The energy efficiency of the wine cellar is obtained by reducing to a minimum the heat exchange between the indoor and outdoor environment. To do this you must create a good insulation of the cellar, or isolate all the components that can create heat and homidity exchange with the outside. These elements are: walls, ceiling, floor, doors and windows. Each of these elements must be isolated as much as possible to ensure a stable situation during the whole year for the important factors such as temperature and humidity. If the insulation of the wine cellar is sufficient to ensure these conditions, the conditioner tasks will be to activate only to maintain the ideal conditions for the storage and aging of the wine, optimizing energy efficiency and therefore consumption. If one of the element is not properly isolated (for example the access door is one of the most critical factors for the isolation of a cellar) and the exchange of heat and humidity with the outside will make necessary a mor frequent intervention of the wine cellar conditioner, or it will make necessary to oversize the air conditioner compared to the real area of the cellar; this will reduce the efficiency increasing the operating costs air-conditioner unit. The most suitable insulation materials for walls and ceiling are polystyrene, high-density polistrirene and the panels of glass wool and rock wool. This type of insulation is ideal for those who want to renovate a local and convert it into a place where preserve and refine wines.
