The floor of the cold storage shall be kept as close as possible during use
Installation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse, the distance between the box bottom and the top of the warehouse must be & amp; amp; gt; 100 mm; The electrical box can be fixed on the building wall or on the angle steel frame.
Heredia.The water-cooled cold storage shall keep the cooling water tower clean and keep the air around the water tower circulating with low temperature, so as to avoid sundries from entering the cooling tower and reduce the heat dissipation efficiency.
Simple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage, so as to cool the refrigerant, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed, large total heat conduction temperature difference and complex system software, so it can only be used in less places, such as brine ice making and cold storage with constant temperature requirements.
.During production in the production workshop, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project not less than 40 & plusmn; 2kg/m3.
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.
Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time, which not only has excellent fire resistance, but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification, with fixed length, total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts 10cm thick cold storage plate, and the raw materials can be sprayed into the brick or concrete warehouse of the cold storage to be built immediately. After shaping, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, etc. Polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance, but the cost is low.
The selection of cold storage is very important for cold storage, because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low, and the air temperature, attention must be paid to the selection of cold storage with better temperature. If the selection of cold storage is not good, the temperature in the cold storage is difficult to, which is easy to cause the deterioration of products in the cold storage or the refrigeration compressor in the cold storage often works, wasting more resources and increasing the cost.
Pressure leak test: the pressure leak test of the fresh-keeping warehouse system is the same as that of the sewage blowing working sample, which is required to be carried out by air compressor. If ammonia compressor is used, the method of segmenting and reducing the pressure difference shall be adopted.
These measures have achieved quite good results. Compared with several cold storages at a customer in Jining, the cold storages using their white materials have significantly lower power consumption than those using other white materials.
knowledge.Polyurethane with good fire resistance and flame retardancy is a kind of refractory and self extinguishing material after adding flame retardant. In case of fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be sealed as a whole after systematic fire prevention treatment to form non combustible products.
Cold storage design steps: selection and preparation of cold storage location. According to the application characteristics, cold storage can be divided into sexual cold storage, retail cold storage and large-scale cold storage. When large-scale cold storage starts to build a planting area with more centralized hand supply, 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, and unqualified products are not allowed to leave the factory.
The three-dimensional automatic cold storage adopts a computer, which can complete the loading, unloading and stacking in the storage, the control of storage temperature and the operation of refrigeration equipment.
retailer.Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required so as to avoid greater damage to the compressor due to untimely warranty.
Degree, suction temperature, motor temperature, crankcase temperature and temperature in front of the valve, observe the frosting of the evaporator and valve, and observe the oil level and color change of the oil mirror. Whether the sound of equipment operation is abnormal.
In fact, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage you should install it from the corner first. Later, according to the height of the cold storage, make a hole in the middle of the insulation board behind the angle iron parts
Heredia.The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.
Various construction materials, such as material certificate, test report and stage acceptance record, shall be carried out simultaneously with the project construction, carefully, timely, accurately and comprehensively reflect the whole process of production and construction, and actively cooperate with the owner in design change and technical negotiation.
During the use of the goods yard medical cold storage project, the distance between the goods and the goods must be cm. At the same time, the distance between the goods and the cold fan should also be 100 cm. No goods can be stored within this range, This is also an important content in the use of medical cold storage engineering.
