Compression refrigerator is commonly used. It is mainly composed of compressor, condenser, throttle valve and evaporation pipe. The evaporation pipe is installed in the refrigeration warehouse. When the liquid coolant passes through the evaporation pipe, it directly absorbs the heat in the warehouse and cools down.The cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference, so as to make the cold storage more energy-saving and improve the working efficiency of cold storage.Amsterdam,If necessary, install a filter on the compressor return pipeline to prevent dirt in the system from entering the compressor and remove water in the system.The factors affecting the installation cost of cold storage are as follows: cold storage construction: the site selection shall comply with laws and regulations and meet the relevant requirements for food hygiene and. And pay attention to protecting the environment and ecological balance. In addition it shall be conducive to production, construction and dry ceremony.KinkalaThe physical properties of polyurethane insulation board are relatively good, and service. It has long been specialized in cold storage installation which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, cold storage installation, cold storage construction, fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.The two sets of connectors between the cold storage shall be wedged tightly, and the two sets of connectors shall be fixed at the upper, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.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, 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.

Disadvantages of multi-layer cold storage: the vertical transportation volume of the warehouse is large, the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance, the foundation construction is complex. High cost; When prefabricated components are used, large construction equipment is required and the construction period is long.In use, the fresh-keeping warehouse must be maintained on time and scientifically. No matter how good the equipment is, without scientific use and maintenance,AmsterdamEnergy saving design of cold storage, its service life and effect will be discounted. Therefore, so as to ensure its stable operation.The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor,AmsterdamCold storage unit installation, the cylinder sleeve, ring and other parts are seriously worn, the long-term cold storage installation, installation, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete,AmsterdamInstall a small cold storage, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.Sampling inspection,Because polyurethane sheet has excellent thermal insulation performance, it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage, it should be determined according to the type, quantity frequency, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..The polyurethane insulation board used in the construction of cold storage shall be integral and continuous, and there shall be no joint in the middle. The junction of polyurethane insulation board, top plate and ground shall be made into fillet arc for transition, which can well meet the health needs.

There are many kinds of cold storage. According to the material, it can be divided into color steel plate, stainless steel plate and salted steel. Among them, color steel plate has strong anti rust ability, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is .mm and mm, without color requirements; The thickness of salted steel plate is .mm, without color requirements; The thickness of PE paint baking board is .mm, .mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm, and the thickness of the vertical plate is mm and mm, which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm, which is suitable for the thermal insulation conditions above ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, including standard plate vertical plate width wa = mm, heaven and earth plate width WB = mm, vertical angle plate W = mm, W = mm, WB and W.Market trend,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.The suction pipeline of the compressor and the return pipeline of the cooling fan shall not be smaller than the size indicated in the sample to reduce the internal resistance of the evaporation pipeline.Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment, and do a good job in rain proof, moisture-proof, anti-collision, anti binding and other safety protection.Amsterdam,Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.Large space rate of quick-frozen warehouse: for quick-frozen warehouses of the same size, reasonable design schemes store more goods than unreasonable ones. For the fixed size quick freezing warehouse, how to design it to maximize its space rate is often an important problem considered by our designers. In the design scheme of Lukang medical quick-frozen warehouse, we reasonably designed to expand the original storage capacity of boxes to boxes, which increases the space a lot.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, functions and designs, so what needs to be understood in cold storage design?
