Introduction Introduction Refrigerator truck structure: The refrigerated truck is composed of the walking part of the chassis of the special vehicle, the heat insulation and insulation body (usually composed of polyurethane material, glass fiber reinforced plastic, color steel plate, stainless steel, etc.), the refrigeration unit, and the temperature recorder in the compartment, etc. For vehicles with special requirements, Such as meat hook car, can be installed meat hook, waist, aluminum alloy rails, ventilation slots and other optional parts. Refrigerated car body production technology: 1. The “sandwich†plate bonding type of split sheets is assembled. At present, larger refrigerated truck manufacturers in China have adopted this technology. Refrigerator vehicles produced using this technology have higher heat insulation performance. 2. Fragmented injection foam type. 3, the overall skeleton injection foam type. 4, vacuum adsorption paste Refrigerator unit classification: The refrigeration unit is divided into non-independent refrigeration units and independent refrigeration units. Domestic units and imported units. General models use external coolers, and a few mini-refrigerators use built-in coolers. For refrigerators with lower temperature requirements, a built-in cold plate (functionally equivalent to an evaporator) can be used. classification Classified by chassis manufacturer: Dongfeng Refrigerated Truck, Changan Star Refrigerated Truck, Qingling Refrigerated Truck, Jiangling Refrigerated Truck, JAC Refrigerated Truck, Beiqi Futian Refrigerated Truck Classified by chassis load capacity: micro-refrigerators, mini-refrigerators, medium-sized refrigerated trucks, large-scale refrigerated trucks According to the type of compartment: the first stage of the development stage of the bread-type refrigerated truck, van refrigerated truck and semi-trailer refrigerated truck Integral injection of foamed metal skin structure. First-generation refrigerated truck manufacturers use this process. This product has a lot of gold on the body The existence of the material is easy to form a large number of cold bridges; on the other hand, the defects injected into the foam insulation layer are not easy to find, and the inherent quality is not easy to guarantee; moreover, since the foam material is used as both an insulation material and a binder, it is easy to produce. Insufficient bonding and other defects, the insulation effect is not ideal, the heat leakage rate (leading to the second stage thermal coefficient) is high. second stage Integral injection of foamed glass steel structure. It is used in second- and third-generation refrigerator car manufacturers. This kind of product has improved one step on the basis of the first stage product, lighter weight, lower heat loss rate (thermal conductivity), better insulation effect, but there are defects such as poor adhesion, easy-to-debride foaming on the outside of the compartment. The third phase Fully enclosed polyurethane plate bonded glass steel structure. It is used in second- and third-generation refrigerator car manufacturers. This product is light and leaks heat (The thermal conductivity) is low and the insulation effect is good. The unsaturated polyester resin is used as a binder, and a cushion layer is further added. The rigid polyurethane foam for the heat-insulating material has low thermal conductivity and high strength. The plate is bonded with a high-strength, high-seal adhesive to form a unitary body. The only drawback is that the loss after the polyurethane cutting is relatively large, so the material cost is higher. Especially in the current situation of high prices of chemical raw materials, the cost of production of cars is getting higher and higher. Such a structure of refrigerated trucks dominates the domestic and foreign markets, and is also a process used by China's representative refrigerated truck manufacturers. Features Containers for sealed refrigerated trucks need to be tightly sealed to reduce heat exchange with the outside world to keep the temperature inside the refrigerator cooler. Refrigerated retrofitted refrigeration equipment communicates with the container and provides continuous cooling to ensure that the temperature of the container is within the allowable range of the cargo. The goods transported by portable refrigerated trucks are usually items that cannot be stored for a long period of time. Even though there are refrigeration equipment, they need to be delivered to destinations faster. Containers of insulated refrigerated trucks resemble containers, but are made of materials with better heat insulation effect, which reduces heat exchange. Key equipment refrigerator car refrigeration unit Refrigerated vehicle refrigeration unit: Provides an endless stream of "cold" important equipment for refrigerated trucks. It is generally installed at the top of the front of the container and has the appearance of an air conditioner, but it has stronger cooling capacity than the same volume of air conditioners. Refrigeration units are generally divided into two types: stand-alone units and non-independent units. The difference is that the independent units generate power for maintenance by completely using another unit. The non-independent units are fully powered by the engine's engine work to drive the group. Refrigeration work. The choice of refrigerating vehicle refrigeration unit Generally, the refrigeration units with different power refrigeration capacities are selected according to the volume of the refrigerator body and the requirements for the temperature of the transported cargo. Refrigerated Vehicle Positioning Management System The refrigerated transport vehicle positioning management system is an open positioning monitoring platform integrating GPS/temperature detection technology, electronic maps, and wireless transmission technologies. Realize effective tracking and positioning management of refrigerated truck resources, and integrate positioning information with business resources of the company. The refrigerated truck location management system not only provides an efficient and flexible management tool for refrigerated enterprises and field staff, but also creates a new and efficient scientific model for refrigerating enterprises to manage and control the refrigerated vehicle resources. This product is suitable for the collection, transmission, recording and over-limit alarm of temperature data in refrigerated compartments. It is an ideal tool for temperature monitoring of transport carts/goods in the refrigeration industry. [1] In response to this, according to the specific needs of enterprises has developed a "RFID cold chain temperature management system" and "GPS + temperature monitoring cold chain management system." Through the combination of advanced RFID technology, GPS technology, wireless communication technology and temperature sensing technology, temperature changes are recorded in the logistics management and production process management of fresh foods and pharmaceuticals that require proper temperature management to ensure quality. "RFID tags with temperature sensors" or "real-time" through the "terminal with GPS and temperature sensing capabilities combined with wireless communication technology upload" to the company's management platform, detailed, real-time product freshness, quality, Management. It is simple and easy to solve the problem of quality control in the food distribution process. RFID tags mainly have the following advantages: RFID tag data storage is large, can be reused, the use of low cost, easy operation, read and write within 30-100 meters long distance; through RFID tags, can be monitored to a different container Different temperatures of packaging units; RFID tags provide ID code, and can continuously record temperature data, have accurate time records, easy to define the delimitation of duty, trace information on aspects, and can quickly grasp the temperature status of the most important transportation in raw freshness management. And to promote the improvement of freshness management in the circulation process; RFID can also be expanded to establish a cold chain detection center platform that covers the whole cold chain process by enterprises or alliances; automatically notify the door opening and automatic registration in the unloading area; effectively manage truck traffic, Real-time monitoring of incoming and outgoing status; shortening waiting time and improving the efficiency of operations; optimizing truck traffic management, thereby accelerating the logistics process of JIS and JIT; reducing the loss of products, improving the safety of product transportation, and improving corporate profits. The refrigerated transport vehicle location management system will provide an effective and beneficial success paradigm in assisting China's logistics industry to break through the bottleneck of the existing monitoring technology and establish an effective cold chain logistics management method. Market Conditions The domestic refrigeration [2] vehicle market is currently dominated by several old-brand companies, such as CIMC Vehicles (Shandong) Co., Ltd., Zhenjiang Feichi Automobile Group Co., Ltd., and Henan Ice Bear Refrigerator Truck Co., Ltd., etc. These companies account for about 70% of the refrigerated market. However, as the prospects for the development of the industry are more and more optimistic, more and more companies will want to come in and get a share. With the development of market economy and increasingly fierce market competition, some professional sub-producers have gradually demonstrated their advantages in occupying the market with their high level of technology, good product quality, advanced management methods and sales services. Such as Henan Ice Bear, Jinan, Kagel, etc. have become the leader of the refrigeration truck industry in China. Some of the refrigerated truck manufacturers that are concurrently working under the guidance of the development strategy of many varieties and small batches will play a role in supplementing and supplementing the market, and will have a positive impact on the development of the industry. In general, the concentration of production will continue to increase. It can be expected that some key enterprises with production and sales volume of 20%-30% will emerge. The rapid development of professional car-plate plants and refrigeration unit production enterprises has made up for some deficiencies of refrigerated truck factories, and has avoided the current phenomenon of companies seeking small but complete, blindly setting up stalls, repeating projects, and dealing with scattered, chaotic, and poor conditions. Play an active role.

How to choose a refrigerated truck first is the chassis of the car: Tonnage, road conditions, etc. of the cargo, considering the structure and carrying capacity of the chassis, fuel economy, emission standards, etc. Compared with the choice of ordinary truck chassis, refrigerated trucks also need to focus on the stability of the chassis, refrigerated trucks transport goods are usually not long-term preservation of the goods, although there is refrigeration equipment, still need to reach the destination faster. At the same time, refrigerated goods have higher requirements for the transport environment. If there is a failure on the road, the goods will deteriorate and the loss will be very high. The second is the choice of the body: The body of a refrigerated truck is different from an ordinary van, and it needs good sealing performance and heat insulation effect, so as to ensure that the refrigerated cargo is in a stable temperature environment. The design of refrigerated compartments is mainly airtight and heat-preserving. Generally, the structure of refrigerated trucks adopts a three-layer structure. The inner and outer skins are made of composite materials, such as glass steel plates, color steel plates, and aluminum alloys. The inner plate material should be made of different materials for transporting different goods. The most expensive inner material plate should be a stainless steel plate. The middle sandwich is a heat-insulating material, and polyurethane foam is mainly used. On the four sides, the glass plate and the polyurethane foam are bonded together with a high-strength adhesive to form a closed plate. In addition to materials, the thickness of the cargo compartment also determines the effectiveness of the insulation. The thicker the insulation layer of the cargo compartment, the better the insulation effect. However, the space inside the cargo compartment will be reduced, and the load of the cargo will be reduced. Users need to follow their own actual conditions. Need to choose the appropriate thickness. Then there is the choice of refrigeration units: Among the three components of refrigerated trucks, the refrigeration unit is the most important part. Because of the small space in the cargo space, the technical requirements for controlling the temperature are also higher. Among the imported brands with higher market share, the United States Carrier, Da Leng Wang, Japan Mitsubishi, Denso, and South Korea Hua Su, Han Xuebing and other brands. There are also many domestic brands. Well done companies include Jinan CIMC Kagel, Henan Bingxiong, and Henan Xinfei. Say good goods are not cheap, the price of imported refrigerators is also very expensive, like the kind of semi-hanging refrigerated truck imported refrigerators, the new cheapest is also more than 100,000. In contrast, domestic brands have obvious advantages in terms of price. For users who pay attention to prices, domestic brands are also a good choice. The power source of the refrigeration unit can be divided into two types: independent and non-independent units. The independent unit has a separate power source. The diesel engine of the unit itself is used as its power source; the power output of the non-independent unit is based on the chassis of the car. Driven by the engine. From the standpoint of cost, the difference between the price of non-independent chiller units and independent chiller units is more than tens of thousands. If the budget is relatively abundant, and the temperature requirement in the vehicle compartment is relatively low (the required temperature is at least minus 10 degrees below), it is still recommended. It's better to use a standalone style. [4]
Refrigerated trucks and cold storage Many goods are now transported without refrigeration, so people install cold storage on transport vehicles. This is the emergence and development of refrigerated trucks, refrigerated trucks. Frozen refrigerated. At present, many large and medium-sized cities use refrigerated trucks for cargo transportation, but their industry penetration rate is very low. Every year, there are still a large number of food, meat, fruits, vegetables, medicines, alcohol, etc., which are caused by deterioration in the transportation process. Unnecessary losses can better explain the large development market of the cold storage industry. The cold storage industry also has a wide range of ways to expand in this area. The restriction on the storage of traditional cold storage vehicles by refrigerated trucks is a great supplement, greatly optimizing the flexibility of cold storage development and developing new channels and space for the development of the cold storage industry. Therefore, while encouraging the promotion of the construction of cold storage, the government must also vigorously publicize the popularity of refrigerated trucks to make up for unnecessary losses caused by the long-distance turnover of goods.

Only the correct use and operation of a refrigerated truck can guarantee the complete delivery and preservation of the goods. Because refrigerated trucks are used exclusively for temperature-sensitive products, the guarantee of temperature is the key to refrigerated trucks. Improper use or improper operation can result in the goods not being stored or shipped in good condition. Preventive maintenance is inseparable from the maintenance and maintenance of vehicles and chillers during our normal use. Only when the equipment is properly maintained and maintained on time, the normal use of the equipment can be guaranteed and the service life of the equipment can be extended. Usually, the chassis engine is maintained and maintained according to the mileage, while the refrigeration unit is designed to maintain and maintain according to the engine operating hours. The usual refrigeration unit is 500-700 hours for maintenance and maintenance. It needs to replace the oil filter, fuel filter, and air filter; and pay attention to check the tightness of the belt, whether the cooling system leaks, etc.; However, the current individual refrigeration units (such as In order to meet the needs of environmental protection, minimizing the damage to the environment and reducing the emission of harmful substances, the United States has used synthetic or semi-synthetic motor oil as an alternative to ordinary motor oil, thereby prolonging the maintenance time of the engine. It is usually done in 2000 hours. maintenance. As a result, the waste of used motor oil is reduced. In addition, scientific experiments show that by using this high-end engine oil, not only the wear of the engine is reduced, but also the fuel consumption of the engine can be reduced. Therefore, scientific maintenance and maintenance can not only ensure the integrity of equipment, but also reduce operating costs. Appropriate packaging for non-ventilated containers for refrigerated goods and side-ventilated packaging for fresh produce. The box must be compressive. Because the frozen goods do not allow the wind to blow from the surface, because the wind blows over the surface of the frozen goods, the moisture in the goods will be lost and the quality of the goods will decline. This year, our country's formulation of bulk frozen foods will not be allowed to sell. There must be packaging sales. Due to its own characteristics, fresh products are still in a breathing state during storage and transportation. If they are not well ventilated, the goods will be deteriorating. Therefore, it must be ensured that such goods have good ventilation and ventilation. Set the temperature to set the thermostat to the required temperature. Pre-cool the car for 1.5 hours to drain the heat remaining in the car. When loading, the refrigeration unit will be turned off and loaded quickly. When loading, the compartment must be pre-cooled or warmed up. Because the vehicle is parked in the open air, the temperature of the passenger compartment is usually the ambient temperature. If the temperature of the conveyed goods is not ambient temperature, the goods are loaded into the car, and the ambient temperature will affect the temperature of the goods being transported, resulting in a change in the quality of the goods being transported. Therefore, the car must be pre-cooled to the required temperature before loading. However, the refrigeration unit must be turned off at the time of loading (unloading). Many people do not shut down the refrigeration unit when loading or unloading goods. In fact, this is a very wrong operation. The reason is: When we precool the cabin, if it does not shut down, open the door of the car, because the fan of the evaporator of the refrigeration unit is working, the front of the fan is positive pressure, and the back is negative pressure, so the cold air from the upper part of the car Blow out, while the lower part will quickly inhale hot air from outside, resulting in a rapid rise in the temperature inside the compartment; if you load and unload cargo after the shutdown, because the fan is stopped, the air flow stops, the air pressure inside and outside the compartment is the same, which makes the external heat The speed at which air passes into the cabin is relatively slow. Pre-cooling insulation . The goods must be pre-cooled to the required temperature. The temperature of the goods is checked at the time of loading. The refrigeration unit is used to maintain the temperature of the goods, not to reduce the temperature of the goods. Many users of refrigerated trucks have a wrong concept. It is always believed that the refrigerating unit on a refrigerated truck can freely freeze or heat the cargo loaded into the carriage to its desired temperature. Therefore, the goods that are insufficient for the transport temperature are loaded into the carriage, and the refrigeration unit is set to its required transportation temperature, and the temperature of the cargo is lowered or raised to its desired temperature over a certain period of time. However, the opposite is true. Not only does the temperature fall (or does not go up), the cargo damages or deteriorates. Because the refrigeration unit of a refrigerated truck does not lower the temperature of the goods, but maintains the temperature of the goods, he packs the goods just like the quilts we used to sell cold drinks. When the external cold (heat) source passes radiation, conduction, and convection into the cabin, it is carried away by the cold air blown by the refrigeration unit and the heat source is cut off from the cargo. Therefore, at the time of loading, the temperature of the loaded goods must be measured first. If the set point temperature of the refrigeration unit is higher or lower than the cargo temperature, the temperature of the cargo in the compartment is difficult to reach the required temperature for transportation. The storage temperature and the transportation temperature of the goods must be the same. If the temperature of the goods changes frequently, the water will be lost, which will cause the quality of the goods to change, which will lead to a shortened shelf life of the goods. Preventing obstruction Even if the capacity of the unit exceeds the actual requirements, insufficient air circulation will be the main cause of deterioration of the items; any obstruction around the cargo may lead to “hot spotsâ€. A qualified refrigerated truck must ensure that there are good ventilation on the six sides of the carriage and there is no obstruction on the six sides of the cargo; good air circulation can ensure that the goods are transported under the proper temperature requirements. The cold (hot) gas blown by the refrigeration unit isolates the cold (hot) source that enters the compartment from the outside and protects the cargo. If a blockage occurs at one location, the cold (heat) source in this section will directly enter the item, causing the cargo temperature to change. Make sure that the return air shutter is in good condition; do not block the inlet of the evaporator (return air); insufficient return air will cause irregular circulation of the cold air and cause the top cargo to freeze. Placement Precautions Goods must be stacked on double-sided pallets; fresh-keeping pallets must not be loaded with reel film; the membrane will block circulating cold air to the cargo; the floor under the cargo cannot be blocked. The general refrigerated truck floor uses vented aluminum rails; however, some refrigerated trucks do not have aluminum rails, and flat anti-skid floors are used. The non-slip floor is usually used as a third-party transportation company or a company transporter for dairy products. The purpose is to be suitable for the transportation of multiple products or to facilitate the cleaning of the ground. However, it must be noted that the loading must be done with double-sided pallets to ensure the circulation of cold air on the ground. It is forbidden to stack goods directly on a flat floor. Do not stack cargo in front of the evaporator outlet, as this will impede the cold airflow; obstruction above the cargo will cause a short circuit in the cold air flow. Maintain a minimum distance of 225 mm between the top of the cargo and the roof. When loading, do not stack the cargo too high. Make sure that the loading height is not higher than the level of the outlet. If the front of the air outlet is blocked by the goods or is too close to the goods, it will not only affect the storage and transportation temperature of the goods, but also affect the normal operation of the refrigeration unit. Because the air outlet is blocked by the cargo, the cold air (or hot air) cannot be circulated in the compartment normally, thus causing the local temperature of the cargo to rise. On the other hand, some defrosting designs for the refrigeration unit use air-induced defrosting. When the goods are too close to the air outlet, the coil in the evaporator of the unit will quickly frost (or ice), the air-sensitive switch will immediately operate, the unit will quickly enter the defrosting state; when the coil temperature rises to 9 degrees (design temperature) About, defrosting ends immediately. As a result, the above-mentioned operation of the unit will be reciprocated, resulting in a phenomenon in which the temperature in the passenger compartment does not fall. The only feeling for everyone is that the crew always defrosts frequently. In fact, it was caused by too much (more) cargo. Keeping the interior of the clean car must be kept clean; there should be no wrapping paper or paper debris on the floor; debris can impede the flow of air or be sucked into the evaporator. When using a refrigerated truck, the interior of the compartment should be kept clean. Due to the effect of the evaporator fan, air circulates in the compartment, causing ground shreds or dirt to be drawn into the evaporator fan. For a long time, a large amount of impurities will be sucked into the evaporator coil, affecting the cooling effect of the refrigeration unit. Because the coil is surrounded by a little bit of impurities, the heat exchange rate of the coil decreases. Therefore, after a few years of use, refrigerated trucks will feel that the cooling effect is worse than the beginning. Besides the cause of the malfunction, it is because the coils are too dirty. Therefore, ensuring the cleanliness of the ground in the carriage is the key to ensuring the normal operation of the refrigeration unit. When the door is opened, the freezer should be closed; the opening time of the door should be as short as possible; use bar-shaped curtains as much as possible when loading and unloading goods. Use partitions to separate dry goods (empty baskets) and perishable items. In order to ensure the temperature of the goods in the carriage, for the delivery vehicles in the city, it is recommended to use a strip curtain to ensure that when the cargo is unloaded rapidly (when the refrigeration unit is not closed), the cold air in the carriage will not be quickly lost. Different temperature goods are forbidden to be stored in the same compartment space. Should be separated by partitions. Because the freezer is used to maintain the temperature of the goods, not to cool down, mixing goods of different temperatures will affect the temperature of the goods and affect the quality of the goods. Correct operation and use of refrigerated trucks is the key to ensuring the quality of temperature-controlled goods. It also ensures that the refrigeration equipment can work properly.
