Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.
Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room, sorting room, quick freezing room, refrigeration room, channel, etc.
Madison.If the refrigerator has been used for more than months, or the high / low voltage switch often fails, please arrange staff to clean the condenser. If the ultra-thin light box is repaired according to the above instructions for many times, and the refrigerator fault still sounds for a long time, please ask the maintenance personnel of the refrigerator to repair it.
During the early operation of the refrigeration unit, carefully observe the oil return of the compressor and keep it clean. If it is found that the oil level is not clean enough or the oil level drops, replace it with new oil in time, so as to avoid bad compressor and reduce the service life of the compressor.
.The insulation board of the cold storage adopts polyurethane double-sided color steel plate. The main effect of this cold storage insulation board is good sealing performance insulation effect and moisture-proof effect, and the cold storage management personnel can timely and effectively open and close the door when entering and leaving so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door, so as to avoid the loss of refrigeration capacity of the cold storage.
2 - cold storage
When the cold storage is built, the diffusion of water vapor and the infiltration of air shall be prevented. When outdoor air invades, it will not only increase the cold consumption of the cold storage, but also bring moisture into the warehouse. Moisture condensation will damp the heat insulation structure and freeze and damage the cold storage structure. Therefore, it is necessary to set moisture-proof and heat insulation layer, professional cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other products, which have a complete variety, sell well at home and abroad, and have a long service life! Products lead the wire industry. Welcome to inquire, so that the cold storage building has good sealing, moisture-proof and steam isolation performance.
How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.
The startup of the air-cooled refrigerator unit shall depend on whether the rotation direction of the fan is correct. If the forward rotation can be started for operation, the reverse rotation indicates that the power wiring is reversed, and the phase sequence must be replaced before startup.
The products stored in the medical cold storage project must be managed by color code, so as to avoid the problem of purchase errors. In the process of handling, it is also necessary to strictly follow the instructions.
Pursuit of excellence.Cold storage is fireproof, flame retardant and high resistance. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage and other special products, 20-year-old brand, price advantage and guaranteed quality. Polyurethane is a flame retardant self extinguishing material after adding flame retardant. Its softening point can be above 250 degrees Celsius and will only be decomposed at higher temperatures. In addition, the ash formed on the surface of polyurethane will be in its foam, and this ash will help isolate the foam below. It can effectively prevent the spread of fire. Moreover, polyurethane will not produce harmful gas at high temperature.
There are many application scenarios of cold storage, which are different. For a long time, it provides various cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, on-site settlement, honest operation, functions and designs, so what needs to be understood in cold storage design?
Thermal insulation performance of thermal insulation materials for food cold storage the requirement of polyurethane thermal insulation materials for cold storage is thermal insulation performance, and the quality of thermal insulation performance cannot be observed before it is really put into use. It is too late to observe the difference between power consumption. In this large number of experimental tests, strict material selection is carried out in order to achieve this goal: using structural amine ether to reduce thermal conductivity and improve thermal insulation effect; Reduce the water content of various raw materials and formulas as much as possible to avoid deterioration of thermal insulation performance caused by water foaming; Polyether: the product of a large processed factory after strict postprocessing is compared with the polyether of small factory without postprocessing. The foam cell has high uniformity of foam pores and thin wall of foam holes, and its heat preservation performance is obviously better than that of ordinary foam with thick wall and big hole. The use of the tasteless amine catalyst can effectively adjust the balance between foaming and gel reaction, so that the interlayer skin of the sprayed coating is thinner, which is beneficial to the performance of the thermal insulation material of the cold storage. Ordinary polyester polyols are not used.

Where is it.Whether the parameters of refrigeration equipment are consistent. When the cold storage leaves the factory, the temperature and temperature difference parameters of the cold storage shall be customized according to the user's requirements. After understanding the technical parameters of the cold storage, set the parameters on the refrigerator. During use, the air humidity is high and the defrosting interval is long. The common cold storage boards of cold storage include 100mm, 120mm, 150mm, 175mm and 200mm polyurethane thermal insulation boards, color steel tiles, stainless steel plates, salt thick steel plates, embossed aluminum plates, polyurethane spraying, etc. on both sides or single and double sides, more general color steel tiles are produced and processed into hidden grooves, which have light weight, high compressive strength, good fire resistance, corrosion resistance and aging resistance, The cold storage board is simple and convenient to assemble and is a wide range of raw materials selected for the heat insulation and heat preservation of the cold storage. The cost of stainless steel plate and salt plate increases, and it is also easy to deform and damage the appearance.
The inlet and outlet pipe diameters of the liquid storage tank shall be subject to the exhaust and outlet pipe diameters indicated on the unit sample.
Technical assurance measures for the installation of cold storage: during production in the production workshop, the production shall be carried out in strict accordance with the operation rules specified in ISO9002 quality operation, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, or does not stop for a long time or stops before the storage temperature reaches.
Before the acceptance and delivery of the project, it shall be treated. There shall be no obvious scratch on the board surface.
