In order to ensure the safety of construction and cold storage operation, the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (100mm thick) has a very large span of 3M, and the polyurethane top storage plate (100mm thick) has a span of 5m.
.As a coolant, make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage, so as to achieve the purpose of cooling.
The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal, it needs to be checked in time.
The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material, which has excellent thermal insulation performance, storage and circulation effect and reduces operation energy consumption. Of course, more important is the choice of refrigeration system. For example at present, the refrigeration system of fluorine refrigerant is still the mainstream, but when selecting the type and power of cooling equipment it is necessary to calculate the data for the installation of cold storage, and then make a high-quality choice.
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, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other products which have a complete variety, and have a long service life! Products lead the wire industry. Welcome to inquire sell well at home and abroad, so that the cold storage building has good sealing, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage, high price, service, on-site settlement, honest management! The holes of bolts and lifting bolts shall be sealed with sealant to prevent cold bridge and air leakage.
Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.
Sales Department.The selection of cold storage is very important for cold storage, and the air temperature, humidity and environmental requirements are relatively high. When selecting cold storage, 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.
According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site, whether it is a single-layer or double-layer warehouse, production process, refrigeration, product stacking, temperature, etc. are used to determine the size and location of the cold storage room, bleach, formalin, etc. Specifically, after the fish comes out of the freezer clean the frost layer on the evaporating pipe group and keep the storehouse temperature below 50 degrees Celsius. Then, according to the volume of 50~100 grams per cubic meter volume of the frozen storeroom, the storeroom door is closed tightly with the sprayer, and the blower is started intermittently, so that the vinegar evaporates and flows in the storehouse, which makes the vinegar absorb a lot of fish smell.
The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.
Manufacturing cost.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, 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.
Measure the winding resistance of the compressor and the insulation of the motor.
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, so that no other adhesive materials are needed. When polyurethane is used as a cold storage project, rigid polyurethane foam is formed between the panels of the storehouse panel, and then solidified and pressed to form a multi shape storeboard, because the metal plate can roll out different waveforms, so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance, but also be economical, applicable and environmental friendly. To ensure the smooth progress of our cold storage project, we should not only inquire about the raw materials of the cold storage, but also the types of cold storage. The common cold storage plates mainly include the following types, namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and 0mm galvanized standard floor plate.
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.
The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam, the deterioration of foam performance is also a very important index. When the white material is prepared, the surface of some polyester materials can make the foam have better toughness and impact resistance, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.
