Factors affecting the cost of explosion-proof cold storage: 1. The location of the cold storage. The location of the cold storage determines the land cost of the cold storage and also affects the electricity cost in the later period. 2. Explosion-proof cold storage insulation materials generally use polyurethane cold storage insulation boards, and the thickness is generally two specifications of 120MM and 150MM. The quality of the cold storage insulation boards will affect the energy consumption during the later use of the cold storage. 3. The cost per square meter of cold storage of different sizes is different. The larger the cold storage capacity, the higher the overall cost and the lower the cost per cubic meter. 4. The choice of cold storage refrigeration equipment, the choice of refrigeration equipment will have a great impact on the design cost of cold storage, there is a certain difference between imported brands and domestic brands. 5. Different cold storage compartments will lead to different cold storage costs for the same volume of cold storage. This is because the number of compartments affects the cold storage refrigeration equipment and cold storage insulation boards. 6. The purpose of the cold storage is different. The design plan is different. It needs to be designed according to the purpose. For example, if you store special industrial materials, you should need an explosion-proof storage. If it is a medical cold storage, it should meet the GSP certification standards. After reading the above introduction, you probably also have a general understanding of the composition of the cold storage cost.

Tubular condensers are classified into three types according to their materials: carbon steel tubular condensers, stainless steel tubular condensers, and carbon steel and stainless steel mixed tubular condensers. According to the form, it is divided into tubular condenser, spiral plate heat exchanger, floating head heat exchanger, U-tube heat exchanger. According to the structure, it is divided into single-tube-pass condenser, double-tube-pass condenser and multi-tube-pass condenser. The heat transfer area is 0.5-500 square meters. Can be customized according to user needs. It is suitable for heat exchange equipment for various purposes in the chemical, light industry, metallurgy, pharmaceutical, food, chemical fiber and other industries. It is especially suitable for condensers to replace the original stainless steel condensers, enamel condensers, graphite condensers, etc. Glass condenser. The effect is remarkable after use.

The condenser takes the refrigerant. The refrigerant is compressed by the compressor into high temperature and high pressure gas and enters the condenser. The condenser is air-cooled or water-cooled to cool the refrigerant and liquefy. After the flow valve enters the evaporator to evaporate and cool, it is sucked away by the suction port of the compressor, which is the refrigeration cycle. The car is heated by the heating water tank, and the household air conditioner has electric heating pipes and heat pumps. The heat pump changes the direction of the refrigerant through a four-way reversing valve. The high-pressure and high-temperature refrigerant gas passes through the indoor evaporator to dissipate heat and then passes through the condenser. Heating effect. Condenser, a component of the refrigeration system, is a kind of heat exchanger, which can convert gas or vapor into liquid, and transfer the heat in the tube to the air near the tube in a very fast manner. The working process of the condenser is an exothermic process, so the temperature of the condenser is relatively high. Power plants use many condensers to condense the steam discharged from the turbine. Condensers are used in refrigeration plants to condense refrigerant vapors such as ammonia and freon. In the petrochemical industry, condensers are used to condense hydrocarbons and other chemical vapors. In the distillation process, the device that converts vapor to liquid is also called a condenser. All condensers operate by taking away the heat of gas or steam.

What are the differences between a quick-freezing cold storage and a quick-freezing tunnel? Many people may not particularly understand. "Quick freezing", also known as "quick freezing", refers to the rapid freezing of food through its largest ice crystal formation zone, and the core temperature reaches -18°C. "Quick freezing" generally includes three process methods: quick freezing cold storage, quick freezing tunnel, and quick freezing flat plate. Today, I will analyze the difference between a quick-freezing tunnel and a quick-freezing warehouse. 1. Quick-freezing cold storage Quick-freezing cold storage, also known as quick-freezing storage. Quick-freezing cold storage usually requires relatively large-scale refrigeration equipment. The cooling capacity of the equipment is directly proportional to the amount of quick-freezing of the food and inversely proportional to the time of the quick-freezing. The quick-freezing storage quickly passes the food through its maximum ice crystal formation area, and the center temperature reaches -18℃. freeze. Food will undergo various changes during freezing, such as physical changes (volume, thermal conductivity, specific heat, dry consumption, etc.), chemical changes (protein denaturation, color change, etc.), cell tissue changes, and biological and microbial changes Wait. The characteristic of quick-freezing food is to keep the original nutritional value, color and fragrance of the food to the maximum extent, that is to say, the quick-freezing cold storage guarantees the maximum reversibility of the above-mentioned changes in the food during the freezing process. The quick-frozen food has the following advantages: 1. Avoid the formation of large ice crystals between cells; 2. Reduce the leakage of moisture inside the cell, and less juice loss when thawing; 3. The contact time of concentrated solutes, food tissues, colloids and various components in cell tissues is significantly shortened, and the harm of concentration is reduced to a minimum; 4. Quickly reduce the food to below the temperature of microbial growth activity, which favorably resists the growth of microbes and their biochemical reactions; 5. The food stays in the cold storage for a short time, which is beneficial to improve the utilization rate and continuous production efficiency of refrigeration equipment. 2. Quick-freezing tunnel The principle of quick-freezing tunnels is the same as that of quick-freezing warehouses. The biggest difference is that quick-freezing tunnels can achieve continuous quick-freezing work and improve production efficiency. 1. Flat mesh belt quick-freezing tunnel: suitable for meat, prepared food, aquatic products, dishes, ice cream, etc. It is a basic general-purpose quick-freezing tunnel. Its output is 100kg/h-2000kg/h. 2. Multifunctional vibrating mesh belt quick-freezing tunnel: a dynamic device is added to the general-purpose flat mesh belt quick-freezing tunnel. In addition to the characteristics of a general-purpose flat mesh belt type monomer quick-freezing tunnel, it is also suitable for the freezing of granular food monomers. 3. Tunnel-type pre-cooling and quick-freezing tunnel: creatively combines pre-cooling and quick-freezing into one to save energy. It is especially suitable for high-temperature incoming goods, cooked food and quick-cooling food, etc. 4. Tunnel type multi-layer mesh belt quick-freezing tunnel: suitable for products with small area and long freezing time. 5. Tunnel reciprocating quick-freezing tunnel: suitable for small area, long freezing time and process reprocessing products. 6. Tunnel-type slab-strip quick-freezing tunnel: suitable for quick freezing of aquatic products. The quick-freezing tunnel transports the goods into the tunnel through the conveyor belt. The goods are quickly frozen after passing through the tunnel, and then transported out for the next step. The food is frozen through the quick-freezing tunnel. As long as the goods continuously enter the tunnel and there is continuous heat generation, the refrigeration unit will continue to operate until the goods stop transporting, and the unit will automatically shut down according to the temperature in the tunnel. It not only improves the utilization rate and production efficiency of the equipment, but also saves the electric energy consumed by the frequent start-up of the unit, which plays a role of energy saving. The difference between quick-freezing tunnel and quick-freezing cold storage is introduced here. Xiaodao Refrigeration, as a well-known brand in the cold storage industry, has been focusing on the field of refrigeration. Relying on the professional level and mature technology in the refrigeration field, it has risen rapidly in the industry. Hope to work together with all parties in the industry to contribute to the development of the cold storage industry.

Technical requirements for cleaning, maintenance and safety of surface coolers of air-conditioning units 1. First close the valve for the unit to be cleaned. 2. In order to prevent the coil and inlet and outlet pipes from scaling when the unit is in use, the refrigerant water should be softened. If fouling in the surface cooler will affect the heat transfer efficiency, the coil should be inspected and cleaned regularly. During operation, dust will accumulate between the coil and the fins, which should be cleaned regularly. 3. Shut down the unit to be cleaned, and turn the switch of the corresponding unit number on the power cabinet to the "0" position, and hang the warning sign of "Someone is working, no operation". 4. Remove the water baffle, remove the filter bag and do a good job of protecting the filter cartridge from moisture. 5. Install and connect the water pipe (pay attention to check whether the water pipes, joints, etc. leak. Especially where there are warning signs, it is forbidden to pass and place water pipes around the "no water ingress" sign). 6. Install power supply and lighting (reliable grounding is required). 7. Carry out cleaning (including humidification section and blower section) (please pay attention to whether the water pipes and joints, and the floor are leaking or stagnant in the cleaning process. If necessary, deal with it in time). 8. If cleaning with chemicals, make sure that the chemicals are cleaned to avoid corrosion of the surface cold and heating coil). 9. After confirming that the fins of the cooling and heating coils are unblocked and the relevant personnel have checked and accepted, remove the water pipes, power supply, etc.; install the water baffle and install the filter bag or remove the filter cover after removing the dirt in the unit. 10. Take out the tools and items inside the unit (confirm that there are no items left in the unit), close the unit maintenance door, and clean the site. 11. Turn the transfer switch of the corresponding machine on the power cabinet to the "AUTO" position. And remove the warning sign of "Someone is working, it is prohibited to run". Notify the staff on duty in the central control to start the machine. After the unit is operating normally, open the valve of the unit. 12. The cleaning is over.

The vegetables are just fresh. Many vegetables and fruits and vegetables that cannot be sold in fruit-growing areas will cause a lot of waste. Some are sold at low prices, and some are simply eaten by pigs as food. If these fruits and vegetables are kept in cold storage, they will be taken when the market is good. It can be sold at a good price, and it will help growers increase production and income without wasting. Although there are many cold storage production and processing enterprises, they have not been comprehensively promoted. Many small and medium-sized farmers have not correctly realized the benefits of cold storage because of high cost, difficult operation and difficult management.

A. During the initial operation of the cold storage unit, carefully observe the oil return of the compressor and keep it clean. If you find that the oil level is not clean enough or the oil level drops, refuel or change the oil in time. This can avoid poor lubrication B. Always observe the operation of compressor equipment, check the exhaust temperature, and pay special attention to the operation when the temperature difference changes greatly during the season. If it is abnormal, check it in time and adjust the condensing temperature and liquid supply of the system C. Judging the sound of cold storage equipment. Listen carefully to the operating sound of water pumps, cooling towers, compressors, fans and other equipment. If they are not in compliance with the routine, they should be repaired in time. For the repair parts, please refer to the vibration conditions of the compressor, exhaust pipe and foundation. D. For water-cooled equipment, check the turbidity of the cooling water frequently. It is necessary to frequently replace the cooling water as necessary. And check whether the water supply system is running, leaking, dripping, or leaking. E. Check whether the water pump is working normally. Whether the moldy switch is effective. If the abnormality should be dealt with in time F. Overhaul and maintenance of the refrigeration compressor of the cold storage: Generally, the refrigerating oil and filter drier should be replaced once the cold storage equipment has been operated for 30 years. Change the situation after half a year. It depends on the specific situation.
