The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. Professional projects include: cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other related businesses. Merchants who hope to have this business please consider the wide scale of warehouse temperature control, the selection and placement of cooling equipment and the description of wind speed field, which are suitable for the cold storage needs of a variety of goods. Equipped with perfect storage temperature active detection, recording and active control equipment.

The construction structure of structural cold storage can be brick concrete structure or steel structure, which can be determined according to their own budget and actual needs. At present, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body unloading platform, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.

Fot.Frequently check and determine whether the working voltage of switching power supply meets the regulations, and the working voltage shall be 220V & plusmn; 10％. When the wholesale of fresh-keeping warehouse equipment is not needed for a long time, the main switching power supply of the freezing warehouse shall be disconnected, and it shall be ensured that the fresh-keeping warehouse equipment will not return to moisture and will not be polluted by other chemical substances such as ash.

Cold storage has good fire and flame resistance. After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.

.2. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room, a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor, and relevant signs shall be set. If the mechanical panel is set in the main room, a button switch shall be added next to each refrigeration compressor.

Installation of refrigeration equipment. The refrigeration system of the cold storage includes evaporator and units outside the cold storage. All equipment shall be installed in accordance with the construction specifications, and corresponding protection measures shall be taken for the installed equipment.

For water-cooled units, the turbidity of cooling water shall be frequently, the cooling water shall be replaced frequently, and whether the running, dripping, leakage and other conditions of the water supply system exist.

The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time, or stops before the storage temperature reaches.

The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. The warehouse has a wide range of temperature control. The selection, layout and wind speed field description of refrigeration equipment are suitable for the refrigeration needs of various goods. Equipped with perfect storage temperature active detection, pay attention to it. If the machine is abnormal, it needs to be checked in time.

Trustworthy.The structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, but the project cost is relatively high.

Frozen and refrigerated storage began to change to shelf and pallet storage to complete the goods according to & ldquo; First in first out & rdquo; It is conducive to improve the quality of commodity storage and reduce loss.

There is a slight sag on the cold insulation board to prevent damage to the cold storage. When standing on the wall,FotCold storage installation works, some soft materials should be laid on the floor of the cold storage tank.

Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction) the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, 4110 polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.

Home page recommendation.The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.

The valve temperature sensing package shall be fastened at the evaporator outlet with a metal clamp for 100mm & mdash; 200mm, tightly wrapped with double-layer insulation.

With the increasing use of cold storage, cold storage board, as an important structure of cold storage, is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore, some small problems may be ignored during installation. According to the following understanding.

Fot.Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level,FotHow much is the installation of cold storage per square meter,FotInstallation price of large cold storage, it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.

Danfoss thermal valve is adopted for the thermal valve of the cold storage with guaranteed quality; Due to the high temperature requirements of the cold storage and the high degree of automation and regulation of the temperature, the temperature system of the cold storage adopts microcomputer full-automatic, does not need special people to operate, and can be remotely controlled. When the temperature exceeds the specified range, it will automatically alarm, which is of great significance to the proper preservation of the cold storage.

Cold storage has good water tightness. Polyurethane rigid foam has low water absorption good permeability to water vapor, foam holes, disconnected and closed porosity of more than 95%. It is a dense microporous foam material, which is more dense than air surface
