Refrigerator door [preferred] Shandong Huayu freezing cold mainly used for food processing and cold storage, it is through artificial refrigeration, indoor maintain a certain low temperature. Cold walls, floors and flat-topped both laying a certain thickness of insulation refrigerator door accessories to reduce the external incoming heat. In order to reduce the absorption of solar radiation, the cold exterior wall surface is generally painted white or light colored. So cold and general industrial and civil construction is different, has its unique structure. Cold storage building to prevent diffusion of water vapor and air penetration. Not only increase the cold outdoor air cooling consumption when the invasion slaughter refrigerator door, but also to the Treasury into the water, moisture condensation caused structural insulated building structures, especially damp freeze damage, so to set the moisture insulation, make cold storage building has a good seal and moisture vapor barrier properties. Ground affected low temperature cold storage, soil moisture is easily frozen. Volume expansion due to the freezing of the soil, ground rupture and cause deformation of the entire building structure, severe cold will not be used. For this purpose cold storage doors, cold storage floor in addition to have effective insulation layer, the lower layer of insulation must be treated to prevent the soil from freezing. Electric refrigerator door electric refrigerator door with a novel and attractive appearance, advanced compact structure, easy Shandong Huayu Machinery refrigerator door operation, durable, rigid, sealing, and does not account for the floor area, open and close flexible and wind, dust, The basic components of the basic working principle of automatic door fire, theft and other characteristics of the electric refrigerator door is substantially the same, with the above structure, coupled with open signal, it can be configured as a simple system of automatic doors. Automatic door system configuration is defined according to the requirements and is equipped with a flat open refrigerator door, automatic door controller peripherals connected auxiliary control devices, such as open source, access control systems, safety devices, centralized control. Must be based on the use of the characteristics of the building. By composition of personnel, building automation system requirements such as reasonable with auxiliary control unit.
