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, and has offices all over the country for long-term cooperation. Different purposes, functions and designs, so what needs to be understood in cold storage design?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, so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door, and the cold storage management personnel can timely and effectively open and close the door when entering and leaving, so as to avoid the loss of refrigeration capacity of the cold storage.Komapa,However, due to high labor intensity and incomplete defrosting, it has limitations.The medical cold storage has been widely used in the industry. For the use of the medical cold storage project,KomapaVegetable cold storage equipment installation, we must combine the performance of the product and store it according to the temperature and humidity required by the product. The automatic temperature box also needs to be used outside the product cold storage. At the same time, the management personnel must be familiar with the operation steps of the medical cold storage project.Shardara,Other aspects: in the design process of food cold storage, ventilation, water and electricity systems. It should meet the requirements of safety, science and environmental protection. When designing and installing the cold storage,KomapaCold storage installation price, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.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, 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 cm thick cold storage plate, cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam, 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.
When opening and drilling is required for the top warehouse plate or wall plate, the internal and external setting out and positioning shall be carried out according to the drawing design requirements, and the opening and drilling shall be carried out after review; The inlet hole,KomapaCold storage production and installation company, liquid inlet hole, return hole, water supply hole and drainage hole shall be opened with a hole opener. Construction treatment shall be carried out in time after opening and drilling, and the orifice shall be closed with foaming material or sealant to prevent air leakage and cold running; The door, vent and delivery port shall be decorated with wrapped edges and fixed with pull rivets, with a spacing of mm and mm outside.Meteorological elements include local average temperature, relative temperature and summer monsoon frequency.Goods are imported and exported frequently and the throughput is large according to the requirements of production and operationEnergy costs,When the cold storage is used for the first time or shut down for a long time, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.The ground insulation of small, medium and large cold storage is different, which is closely related to the purpose, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done, otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, which affects the quality of stored goods. So, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?The drainage at the outlet of the cooling fan, the drainage of the volatile cooler and the road drainage of the refrigerated warehouse storing food or drinks shall not be immediately connected with the sewage and wastewater pipeline system software, but indirect drainage shall be adopted. For the flushing (thawing) water drainage of each layer in the double-layer cold storage, an exhaust valve equipment shall be set in front of the main riser for flushing (thawing) water drainage.
When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.OK or not?,During the installation of long-span top warehouse plate, if the supporting steel beam has been installed in the warehouse, the top warehouse plate and the supporting steel beam shall be fixed with pull rivets during the installation of each warehouse plate, and each top warehouse plate shall be riveted in two rows; If the lifting point type is adopted the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate, and when the exhaust pressure increases so as to ensure that each lifting point can be installed at the same time during the installation of the top silo plate; The lifting point shall ensure that there are at least two points along the width direction of each warehouse plate.The suction pressure of fresh-keeping storehouse remains unchanged the exhaust temperature increases; If the exhaust pressure remains unchanged, when the suction pressure decreases, which should be prevented. Too high exhaust temperature will dilute the oil and even carbonize and coke, which will worsen the compressor conditions of the fresh-keeping warehouse.The foaming technology of polyurethane with strong stability makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is, under the unfavorable local temperature and humidity conditions, it can bear various internal and external combined loads such as wind force, self weight and normal collision, and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.Komapa,When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure especially the heat insulation structure, being damaged by moisture and freezing. Therefore, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.Other aspects: in the design process of food cold storage, it is also necessary to consider the cooperation between the cold storage and on-site fire fighting, ventilation, water and electricity systems. It should meet the requirements of safety, science and environmental protection. When designing and installing the cold storage, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every ℃ increase in the evaporation temperature of the cold storage can save energy by ~ . Therefore, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.
