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.Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.Candlestick,Air volume regulation is the key factor to save energy. If we can do this well, the energy-saving effect of the fan can be determined. After effective adjustment, the fan can meet the flow or pressure requirements of production under the stable working conditions, and can save energy to the limit. In the process of implementing fan regulation, it is important to choose what regulation, which can directly affect the energy-saving effect of controlled atmosphere storage.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.Pohang,The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. Professional projects include: cold storage installation installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other related businesses. Merchants who hope to have this business please consider the wide scale of warehouse temperature control, the selection and placement of cooling equipment and the description of wind speed field, which are suitable for the cold storage needs of a variety of goods. Equipped with perfect storage temperature active detection, recording and active control equipment.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, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.Generally speaking, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing, firmness and frost resistance.

Generally, because the temperature conditions are constantly changing,CandlestickDrug preservation warehouse, only by relying on the careful operation of the cold storage management personnel and accurately adjusting the operation of the refrigeration equipment of the cold storage, can the refrigeration system always be in the ideal working state and achieve the effect of energy saving.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,CandlestickPharmaceutical warehouse management system, 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,CandlestickHow much does it cost to install a small cold storage, etc.In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.Safety production,Install the electric control system. The electric control system of the cold storage mainly includes electric controller, electric door, lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.Initial stage of cold storage equipmentWe must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.

Polyurethane with good fire resistance and flame retardancy is a kind of refractory and self extinguishing material after adding flame retardant. In case of fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be sealed as a whole after systematic fire prevention treatment to form non combustible products.How many?,Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.When the actual scheme is determined, sometimes two defrosting schemes are adopted, and sometimes different schemes are combined. For example, the shelving, wall and top smooth pipes of the controlled atmosphere storage can be manually combined with the hot gas method. The frost can be manually swept at ordinary times, so as to thoroughly understand the frost that is not easy to be removed by manual sweeping and the oil accumulation in the pipeline. Cold fan water flushing and hot gas method. Hot air combined with water can be used for defrosting if there is a lot of frost and the controlled atmosphere storage needs to be defrosted frequently.Points of multi-storey cold storage: small, which can save land; When the storage capacity is the same, the surface area of the outer enclosure structure is smaller than that of the single-layer cold storage, so that the cold consumption can be reduced, the dry consumption of food can be reduced, and the machinery and equipment cost and operation and management cost can be reduced accordingly. At the same time, due to the saving of thermal insulation materials, the civil construction cost per unit area is low and the investment cost is small; The multi-storey location can be reasonable, such as the cooling room can be used as the cold storage room, the attic on the top floor can be built into the ice making room,In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank. - Installation of the vertical plate of the cold storage: select the angle first according to the site conditions and locate it (i.e. lock the vertical plate and the floor) to extend to both sides at this angle. Only lock the vertical plate and the vertical plate, and locate it when it meets the vertical angle. Put the beautiful plate in a conspicuous place. When installing it on the side of the evaporator, make the drainage pipe in advance and make U-bend and silica gel outside the storage.The cold storage shall be regularly overhauled and maintained, so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.
