The construction of refrigerated warehouses and premises provides for mandatory thermal insulation in order to reduce the flow of heat from the environment and the loss of cold.

As an insulator, we recommend using the material, since it meets the necessary requirements for thermal conductivity and density, as well as other parameters: chemical inertness with respect to the materials with which it contacts, no smell, frost resistance, fire safety, resistance to penetration of rodents and action of fungi and microorganisms.

An important aspect of the insulation of refrigeration facilities is the absence of the need for an additional waterproofing layer.

Isolation of vegetable storehouses

In the construction of warehouses and vegetable stores the most important task is to maintain a constant optimum temperature. To solve this problem it is necessary to choose the right insulation. From this choice also depends on the further costs of heating and terms of operation of the room.

Stock

In addition to the “standard” set of necessary properties of insulation (low thermal conductivity, durability, ease of installation), an important role is played by the ability of the material not to absorb odors and moisture, as well as to resist such a common problem as rodents. The company has such properties, and it is much cheaper than other popular materials (for example, polyurethane foam).

Insulate the enclosing structures of refrigerators, appliances and pipelines. The enclosing structures of refrigerators include external and internal walls, floors, and roofing. For the Insulation replacement this is really important now.

Walls

Usually the walls are made puff. The outer layer from the warm side of the chamber is plastered and vapor and heat insulation is glued onto it. More progressive is the use of standard unified prefabricated elements (panels), which make it possible to increase the degree of readiness of building elements, to reduce the weight and cost, of walls by 27-40%. The most important achievement of construction equipment is the use of prefabricated refrigerators with sandwich panels.

In the construction of refrigerators, both vertical and horizontal reinforced concrete and expanded clay concrete panels are used. The height of the vertical panel is usually equal to the height of the floor, and its width is chosen taking into account the lifting capacity of construction cranes.

When calculating the insulation design, the heat transfer resistance of the fence is determined from the known characteristics of the layers of the fence and the thickness of the insulation by a predetermined heat transfer coefficient. The initial data are put into account in such a way as to ensure the necessary service life of the refrigerator, which is more dependent on the durability of the insulation structures. The durability of the insulating structures of refrigerators is influenced by climatic conditions and temperature and humidity conditions in refrigerated rooms. For class II refrigerators, the service life is taken from 50 to 100 years (in fact, it is shorter due to thermal insulation failure.).
