Refrigerator selection and maintenance

The refrigerated truck regulates the operation of the chiller by setting a control system. The temperature in the compartment is maintained at 2 to 8°C and the relative humidity is in the range of 35 to 75%. By setting the temperature recording and alarm system, the temperature and humidity data can be recorded, saved and updated in real time. When there is a violation, it will automatically alarm.

When buying refrigerated trucks, we should pay attention to some issues: Before we buy refrigerated trucks, we must first locate the refrigerated trucks we want to buy based on the actual market conditions that we know about the difference. That is how much you can buy a refrigerated truck to meet the needs of your market. As the country’s requirements for automobile emission standards are increasingly stringent, we must understand the requirements of licensing on the local vehicle management agency: whether it is a national standard or a national standard, because there is a difference between the two standard car prices. Million; after the refrigerated truck's size orientation, we have to locate the brand of the auto brand and refrigerated truck unit that we want to buy according to our economic budget. After doing the first two items, we will conduct a number of price comparisons. Of course, when we make an inquiry, we must pay attention to the cost-effectiveness of quality and price. We must not only be willing to buy cheap products, nor can we ignore the quality. Of course, some manufacturers in your inquiry will say how their products are good, how the quality is how strong, this time we must not believe in a word, it is best to visit the car after the site inspection.

After determining the above points, how can we get a better refrigerator ? Micro-refrigerated vehicles: This kind of refrigerated trucks are generally used for urban distribution, and the most commonly used ones are basically Futian Yulin and Changan. Generally, the Shanghai Songkang cold truck or K brand is equipped with a mass temperature of - 5°. This price is generally 5-6 million. The advantage is that it is flexible and it is basically possible to play on any area. Small refrigerator cars: The more commonly used ones are Futian, Dongfeng, Jianghuai and Isuzu. Among these, the cheapest of the 4.2-meter long box was Futian Xiangrui’s, and the most expensive course was Isuzu’s. According to the refrigerating car unit and car body insulation effect prices from 60,000 to 200,000, the highest cost-effective I personally think that when Dongfeng Frerica, the price is not much more expensive than Futian Xiangrui, but the power and other aspects of configuration There is a big improvement. Medium-sized refrigerated trucks and large-scale refrigerated trucks should be comprehensively considered in consideration of various factors. Refrigerated truck units are commonly used in China: Songhan, K brand, Hanxue, Hanya, Lengwang, Carrier

The price of a refrigerated truck differs depending on the choice of chassis and the cold machine it is equipped with. The specific purchase depends on what kind of business your vehicle is engaged in. If it is ordinary fresh-keeping transportation, you can choose a unit with a temperature of -5°C. If you want to freeze, you must choose the -18 °C refrigeration unit!

Operation procedure; Start the vehicle, open the power control box, push the power supply switch, and turn on the temperature control system and the temperature and humidity recorder. In the temperature control system set the refrigeration unit startup temperature of 7.0 °C, shutdown temperature of 3.0 °C. Alarm parameters are set in the temperature and humidity recorder: upper temperature limit 7.5°C, lower limit 2.5°C; upper relative humidity 75%, lower limit 35%. Record the temperature and humidity every 2 minutes in the temperature and humidity recorder, and update the temperature and humidity data every 1 minute. Inspection: Before starting, check and confirm the hygienic condition of the carriage. The interior of the carriage must be kept clean and free from debris, debris and other debris. Refrigeration unit, pre-cooled to 3 °C, shut down the refrigeration unit. When loading medicines into the carriages, it is necessary to pay attention when loading the goods: The goods must be placed on the pallets to keep the floor ventilated. The drug release height must not exceed the lower edge of the outlet of the refrigeration unit. Allow enough ventilation space between the medicine and the carriage. The ventilation distance between the medicine and the front panel shall not be less than 15 centimeters from the front panel, and shall not be less than 5 centimeters between the rear panel, side panel and bottom panel. After loading, close the carriage, check the closed condition of the carriage door, and start the refrigeration unit. Check before departure. Check whether the internal and external fans are operating normally and whether the cooling is normal. Check whether the door seal is tight and whether the carriage is kept warm. Check whether the temperature and humidity recorder records normally. When the lower limit of temperature is reached, the refrigeration unit will automatically stop working. When the upper temperature limit is reached, the refrigeration unit will automatically start working. When the temperature reaches the range of 2-8 °C, after passing the inspection, release the car. In the middle of loading and unloading, the refrigeration unit should be turned off before opening the door, and should be fast-forwarded and closed when unloading. The opening time should not exceed 2 minutes each time; if the goods are unloaded in batch, the temperature in the compartment should not exceed 5°C. Split. During transportation, balance cooling should be maintained and recorded using a temperature and humidity recorder to monitor temperature changes in the cargo compartment. The GPRS system is used to transmit refrigeration truck temperature data to the company in real time.

The monthly temperature and humidity recording data are periodically exported from the recorder and saved. Keep at least 5 years. In the temperature and humidity alarm system, set the mobile phone reception personnel (storage and transportation department manager, transportation supervisor, and maintenance staff) who have exceeded the temperature alarm information. When the cold storage temperature exceeds the preset range alarm, the responsible person shall, after receiving the mobile phone information alarm, guide and supervise the transport personnel for the first time. 4.13 When abnormal conditions such as abnormal temperature changes, unrecoverable cooling of vehicles or refrigeration equipment, etc. are found, they shall be dealt with in accordance with the “Contingency Plan for Storage and Transport of Refrigerated Medicines”. 5. Maintenance and Maintenance It is forbidden to use forklifts or other hard objects and other impacts, resulting in damage to the inner wall, cracking of joints, and damage to the heat insulation layer. Check the door seals and drain covers, and repair or replace them according to the situation. Rinse regularly or thoroughly with water to remove debris and debris from the floor and drain holes. Wipe the fan regularly, remove dust from the radiator of the refrigeration unit with (soft brush, clean cloth)
