How do you insulate a wine cellar?

When the wine cellar is used, the wine cellar inside and outside the general existence of temperature difference, if the wine cellar is not insulated, heat exchange will make the indoor and outdoor temperature difference tends to zero, which increases the workload of constant temperature and humidity equipment, shortening its life expectancy, and at the same time, the temperature in the wine cellar is difficult to reach the ideal state.

So in order to control the temperature, the wine cellar should be well insulated, which is a very important part of the wine cellar design. If the design of the wine cellar insulation construction is not in place will bring serious consequences and pitfalls.

First, the serious consequences of hidden danger

1, the temperature can not reach the wine storage standards, the wine is at a higher temperature for a long time, so that its fermentation speed, or deterioration.

2, the constant temperature state maintains a short time, making the thermostatic equipment to operate for a long time, which costs electricity and reduces the life of the thermostatic equipment.

3, the temperature is not uniform, the indoor temperature is slightly higher, the wine racks and bottles produce condensation, the wine racks are easy to change shape, the wine label is easy to mildew and fall off

Second, the specific methods of wine cellar insulation

Wine cellar walls and top ground must do insulation treatment, the wall needs to be measured, calculated to get a more accurate value to meet the storage requirements of each space. Commonly used insulation methods are the following three.

1, extruded plastic board insulation

First of all to do in the place of insulation on the keel, and then cut the extruded plastic board into the desired size, stuffed in the middle of the keel, fixed with foam, this extruded plastic board insulation layer cost the lowest, of course, the effect of the insulation layer is general, but for the basement of the cellar in terms of the general is enough;; 2, polyurethane board insulation layer.

2, polyurethane board insulation

In fact, the treatment is the same as the extruded plastic board. Mainly divided into three steps.

First of all, in order to do the insulation layer of the foundation above the keel, generally every 60 centimetres to play a keel, keel fixed, the polyurethane board cut into 60 centimetres wide, and then the polyurethane fixed between the keel. Then fill the gaps with foaming agent. This practice has a better heat preservation effect, so the cost is slightly higher than the extruded plastic board insulation layer.

3、Polyurethane whole foam

By spraying polyurethane cool to the base of the insulation layer to be made to foam, this method can be adjusted according to the requirements of the thickness of the insulation layer, but also can choose the density of the insulation layer. But this kind of insulation layer in the production process is more complex and cumbersome, the production equipment is too large, so although this method of insulation layer effect is very good but for some small wine capacity for the cost of larger, the cost is relatively high.

Third, the advantages of hexahedral insulation technology

1, six-sided thermal insulation technology, to do the wall, top, ground six-in-one thermal insulation construction, thermal insulation five dead ends! Greatly improve the service life of constant temperature and humidity system and wine capacity.

2, winter, when the outdoor cold air through the wall insulation material will be effectively blocked, so as to maintain the temperature of the wine cellar in the winter; summer, the wall insulation material will also prevent solar radiation and external heat into the room, both in the wine cellar to create a warm winter and cool summer comfortable environment.

Fourth, the envelope insulation structure

Moisture-proof layer, insulation layer, reinforced protective layer, moisture-proof layer and decorative layer.

Good insulation of the envelope is very important for the wine cellar. Even if the wine cellar is built in the basement, but due to seasonal differences and heat transfer between different room temperatures, the temperature and humidity of the wine cellar will have relatively large fluctuations.

At the same time, the load on the wine cellar air-conditioning unit increases and energy is wasted. If the design and construction of good thermal insulation of the enclosure structure, the heat transfer through the enclosure structure and the outside world will be greatly reduced, and can be accurately controlled temperature and humidity accuracy.

At the same time, the load of the wine cellar air-conditioning unit is very small, energy consumption is also very small, both to extend the life of the wine cellar air-conditioning unit, but also to save energy.
