Description
- The present invention relates to a refrigerated display counter with an improved insulation system.
- Refrigerated display counters are known on the market and used to display ice cream contained in tubs, and also to display pastry items.
- Such refrigerated display counters are provided with a refrigeration system suitable for refrigerating a refrigerated compartment that contains the products to be displayed.
- The temperature of the refrigerated compartment must be kept within a wide range, which can vary from -20°C to +20°C. In fact, ice cream must be stored at approximately -20°C, pastry items at approximately +4°C and pralines at approximately +20°C.
- The refrigerated compartment is obtained by means of insulation panels that generally consist in sheet metal or plastic walls that define a cavity wherein polyurethane foam is injected with a density of approximately 40 Kg/m3.
- This type of insulation panels is impaired by some drawbacks because of the fact that said panels do not guarantee a good thermal insulation. In view of the above, panels with a thickness of approximately 50-60 mm must be used.
- Therefore, the refrigerated display counters of the prior art have a large volume because of the high thickness of the panels. Such a drawback is especially experienced in the case of small shops, where a very small space is dedicated to the refrigerated display counter because of the small dimensions and of the high rent of the shop.
- Vacuum panels, which are normally defined as "Vacuum Insulation Panels (VIPs)" are known on the market. These panels use the insulation power of vacuum to increase the thermal resistance compared to traditional panels. Vacuum panels are obtained with a tight film that creates a chamber filled with a filler where vacuum is created.
- This type of vacuum panels is generally used in the aeronautics industry or for laboratory applications at cryo-temperatures.
- The vacuum panels are impaired by the fact that they are extremely fragile. In fact, if the film is perforated, the vacuum inside the panel is lost and the panel loses its insulation properties.
- For this reason, vacuum panels are not used for refrigerated display counters. In fact, refrigerated display counters are continuously handled by operators and users, who may damage the vacuum panels and impair the insulation properties of the refrigerated compartment.
