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 & plusmn; kg/m.The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.lubbock ,Screw refrigeration unit: screw refrigeration unit can be divided into non single screw refrigeration unit and twin screw refrigeration unit. It is widely used in refrigeration devices such as refrigeration, HVAC and chemical technology. The input power range has been developed to -kw,lubbock Cold storage of professional installation company, and its research and development fields are widely divided, with great potential for performance optimization.Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.Guiglo,In the low temperature environment, especially in the periodic freezing and thawing cycle, the building structure is also vulnerable to. Therefore, the building materials of the cold storage and the structure of each part of the cold storage should have sufficient frost resistance.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.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, 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, 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, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.

Secondly, since the cooling of the compressor is not continuous, the multi work operation at night can be selected if possible. When working at night, the external temperature is low, coupled with the equal role of the cold storage board, reduces the power operation of the compressor and achieves the purpose of energy saving.The function of refrigeration is & amp; amp; ldquo； Low temperature storage & amp; amp; rdquo； Introduction & amp; amp; ldquo； Loop type & amp; amp; ldquo； Cold chain logistics & amp; amp; rdquo；Polyurethane spraying is widely used in large and medium-sized refrigerators. Different well-known brands are produced at different prices, and the product quality is relatively large. However, it is not high-quality or good goods. This is the result of long-term cooperation.Encyclopedic knowledge,General quick-frozen warehouses are mostly cooled by refrigeration mechanisms, and those with very low gasification temperature are used as coolant to evaporate under low pressure and mechanical conditions, so as to achieve the purpose of cooling and reduction.Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and in the production process of cold storage, there will be no condensation in the cold storage of the plant. Condensation inside the cold storage or inside the insulation layer is harmful. Irreversible damage or deformation occurs in the new external insulation, and the external surface temperature of the external wall changes sharply. For example, the insulation and sound insulation effects of polyurethane insulation board are relatively good, which can be used in many industries. As we all know, the cold storage has great requirements for the thermal insulation effect of building materials. If the thermal insulation effect of building materials is not good, the cold storage will consume more energy during operation, and can not guarantee a good refrigeration effect. The performance of polyurethane insulation board meets the construction requirements of cold storage, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next, let's understand the physical properties of polyurethane insulation board.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, and tighten the angle iron parts until there is a hole on the insulation board

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,lubbock Tea cold storage, the air humidity is high and the defrosting interval is long. The common cold storage boards of cold storage include mm, mm, mm, mm and mm 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.Where can I find it?,Installation of cold storage construction of cold storage, fruit preservation cold storage and medical cold storage have stable, reliable and maintenance free performance. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time, and it must not be knocked during cleaning, so as not to damage the ground and affect the service life of the cold storage.Wires should not be in the open air to avoid long-term sun exposure and wind blowing, wire skin aging, long-term cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage without turnover, so as to avoid price difference and the price is % higher than the market price! The price of more than one ton is higher! Short circuit, leakage, etc.During production in the production workshop,lubbock How to install the cold storage unit, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project, not less than & plusmn; kg/m.lubbock ,Wall and floor fixtures shall start at corners. According to the plate layout drawing, transport the two plates at the corner of the required device to the device location. According to the plate beam height and the model of the angle iron for fixing the mushroom head nylon bolt, drill a hole at the corresponding elevation in the middle of the plate width. When drilling, the electric drill should be perpendicular to the plate surface. Put the mushroom head nylon bolt in the hole, tighten the angle iron, and tighten it horizontally, so as to make the nylon bolt on the surface of the warehouse plate slightly concave. When setting up the wall panels, foam data and other soft data should be laid on the floor slots along with the floor of the storehouse, so as to avoid damaging the storehouse. After the two corner panels are neutrally removed from the floor, the plane position of the wallboard and the verticality of the storehouse should be adjusted in time according to the location of the laying line, and check whether the top elevation of the wallboard can be correct. After the position of the wallboard is correct, weld the angle iron on the plate beam and fix the inner and outer corners. When welding the angle iron parts, the angle iron parts of the warehouse plate shall be covered with a shield to avoid the high temperature of the welding ground baking the warehouse plate and welding slag on the warehouse plate during electric arc welding.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, installation of cold storage professional cold storage installation, 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.In the low temperature environment, especially in the periodic freezing and thawing cycle, the building structure is also vulnerable to. Therefore, the building materials of the cold storage and the structure of each part of the cold storage should have sufficient frost resistance.
