During the production of cold storage, width and thickness according to the needs of various cold storage projects. Generally, cm thick cold storage plates are selected for high and medium temperature cold storage. The requirements for cold storage engineering plates of low-temperature storage and quick-frozen storage will be higher. Professional cold storage installation, installation, construction, fruit fresh-keeping cold storage and medical cold storage ensure the quality, Guarantee service. Guarantee quality. Your satisfaction is our pursuit! Welcome to inquire. In this case, use cm or cm thick library board. When you budget the cold storage project, you can make a reservation according to the specific conditions of your cold storage temperature. If you don't make a reservation for the cold storage plate,KomitanchiloInstallation of vegetable and fruit cold storage, you should pay attention to the density of the cold storage plate and the thickness of the steel plate when purchasing the cold storage plate. According to regulations, the foaming density of cold storage is per cubic meterCold 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.Komitanchilo,Because our large-scale fresh-keeping warehouse is generally composed of many thermal insulation boards and the gap between each board is the place that needs maintenance. During construction, these gaps will generally be sealed with sealant, but if it is found that there are seal failure departments in the fresh-keeping warehouse during use, its installation quality will directly affect the temperature of cold storage. As an important structure used in the cold storage, the cold storage board should pay attention to the details of its installation, find out the problems that are easy to be ignored,KomitanchiloInstallation price of cold storage, and avoid the wrong installation, which will affect the use of the cold storage or the whole installation process, so as to waste resources and increase the cost.Wakiso,Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate, fuse is blown, thermal relay acts, high voltage switch acts, compressor is locked, line is falsely connected or loose fault phenomenon: it stops in a short time after drying, ambient temperature is too high, condenser is blockedGoods are imported and exported frequently and the throughput is large according to the requirements of production and operationThe construction structure of structural cold storage can be brick concrete structure or steel structure, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body, unloading platform, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.
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.If the warehouse is relatively small and you want to transform a miniature fruit fresh-keeping warehouse you should ensure that the height in the warehouse is at least meters, because the top of the cold storage and the top of the warehouse should reserve a height of at least cm.Generally speaking, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing, firmness and frost resistance.OK or not?,Improper adjustment or blockage of throttle valve, too large or too small refrigerant flow: improper adjustment or blockage of throttle valve will directly affect the refrigerant flow into evaporator. When the throttle valve is opened too large, the evaporation pressure and evaporation temperature also increase, and the decline rate of warehouse temperature will slow down; At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow will also decrease, the refrigeration capacity of the system will also decrease, and the decline rate of warehouse temperature will also slow down.The wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials making the whole structure have the advantages of light weight, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.
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 absorb the heat in the warehouse,KomitanchiloFruit preservation warehouse, so as to achieve the purpose of cooling and reduction.Development Curriculum,The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.How to judge whether the controlled atmosphere storage is bad and the effect is poor? Under the same conditions the required temperature can be reached in minutes, but now it takes minutes. In this way, the refrigeration is obviously slow and the effect is poor, which will directly affect the use cost.The installation of top warehouse plate should be carried out alternately with the installation of wall plate, and the wall plate should leave a gap for withdrawing construction equipment; During the installation of the top warehouse plate, the end steel sheet at the overlap with the wall plate shall be disconnected for mm to prevent the cold bridge from running cold; Two layers of foaming materials shall be evenly and continuously punched on the joint surface between each top warehouse plate. Rivets shall be pulled and fixed at the internal and external lap joints of the steel plate, and the rivet spacing shall be mm; According to the design drawings, if there are supporting beams, columns and supporting steel frames in the warehouse, the setting out and positioning shall be carried out and accurate and clear marks shall be made according to the requirements of the design drawings; Weld or install the support beam, column, support steel frame, etc., and the welded junction shall be moisture-proof and treated according to the drawing requirements.Komitanchilo,The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.Commissioning cold storage. After all parts of the cold storage are installed and connected, the cold storage can be started for cold storage commissioning. According to the needs of customers, the cold storage can reach the predetermined temperature, the cooling speed and the operation of the cold storage are normal, and the cold storage can be delivered for use. The cold storage installation unit shall also provide the cold storage user with training on cold storage use and management knowledge, as well as some after-sales training.What should be considered in building a cold storage? In these aspects, food cold storage is a systematic project of artificial refrigeration to ensure food quality and reduce food decay in a low-temperature environment.
