The cold room is a refrigerated room that is built on the chassis of food and pharmaceutical transport vehicles and mobile cold stores all over the world to distribute materials that spoil at ambient temperature and the only way to transport them is to use a refrigerated truck or van. It is a refrigerator room, for the insulation of portable refrigerators and car refrigerators with a refrigerator room and to prevent the transfer of heat from the outside to the inside of the refrigerator room, from sandwich panels with special double-sided sheets pre-painted with polystyrene ps or polyurethane insulation. pu is used, or xps insulation foam double-sided polyvinyl chloride PVC sheet or xps insulation foam sandwich panel covered with aluminum composite sheet can be used. Nowadays, all kinds of trucks with different temperatures and in smaller dimensions can be produced, which due to the progress in smallness and lightness and the variable speed of advanced compressors, it is possible to produce small vans with low consumption and very negative temperatures with insulation. Extruded polystyrene foam (xps foam) which lasts up to 30 years and does not change in insulation properties is the best option.
Technical Suggestions of Refrigerated Room insulation:
The best cold room insulation is xps extruded polystyrene foam
The most resistant insulation against the load and compressive strength of xps foam
It is the cleanest and most hygienic insulation of xps foam.
The lightest insulation in resistance It is high pressure xps foam with easy installation on the refrigerator room on all types of chassis
isolation and impermeability of xps insulation compared to other insulations
no penetration of water vapor and preventing Farak
The production height of xps sheet is up to 6 square meters and smaller dimensions and the possibility of easy cutting. >Thickness more than 10 cm with the use of bonding system
Loadability and compatibility with the lighter chassis, installation work of the refrigerator
Lower thermal load capacity of the compressor due to insulation Efficient extruded polystyrene foam (xps foam)
Exact dimensions of xps foam sheet in production and production error of a few millimeters
Types of insulators used in refrigerated pickups:
The insulation in the refrigerated van is responsible for keeping the cold air inside the van and preventing heat from entering. There are three main types of insulation used in refrigerated vans, including:
Polyurethane foam: Polyurethane foam is the most common type of insulation used in refrigerated vans. It is placed on the walls, roof and floor of the car and creates a seamless insulating barrier. Polyurethane foam is light, strong and has excellent insulating properties.
Polystyrene foam: Polystyrene foam is a lightweight and cost-effective insulation option for refrigerated vans. It consists of tiny grains that expand when exposed to heat. Polystyrene foam is not as good an insulator as polyurethane foam, but it is still considered an economic option.
Insulation of refrigerated vans is done to maintain the temperature inside the vans. These insulated vans are usually used to transport different foods such as: ice cream, dairy, meat, etc. These cars can be of any size and shape. Proper temperature can be maintained with minimum heat loss through proper insulation. The insulation properties of polyurethane foam are much better than other insulation materials, hence it is preferred over other insulation materials. The thickness of the insulation varies depending on the ambient temperature and the internal temperature of the tank that must be maintained. The density of polyurethane foam is about 40 kg/m3. Higher densities are also produced based on customer needs
Polyurethane-based insulations are used in countless areas in the field of transportation. Vehicles of all types and sizes, on land, on water or in the air, move passengers or cargo and need a light and strong insulation. Rigid polyurethane foam is an essential component for refrigerated truck and van bodies and is used by leading manufacturers around the world to ensure thermal efficiency and climate control. Polyurethane foam also has excellent insulation value, which is superior to traditional materials such as cellulose, mineral wool and fiberglass. Polyurethane foam also offers excellent structural improvement, sound reduction and moisture control.
Rigid polyurethane foam insulation contributes greatly to sustainability and eco-design by reducing the energy required to keep refrigerators and freezers cold. . Rigid polyurethane foam is the insulation material that is most widely used all over the world for refrigerators and freezers. The insulation performance of polyurethane foams is a key feature for maintaining low food temperatures during processing, storage and distribution to the consumer. Without polyurethane insulated refrigerators, approximately 50% of the world's food would rot, severely affecting our daily lives and food-related businesses.
