Why Your Vehicle Refrigeration Units are not Refrigerating?

Some drivers may find that their vehicle refrigeration units have a better refrigerating effect at the first time when they buy it, but after works for a long time,maybe several months or 1 year, the transport refrigeration unit is not refrigerating well. So why this condition happened and how to solve it? Let’s see the detail reasons that may result in this bad refrigerating happening.

Bad air flow around the refrigerated truck body block the evaporator inlet
Airless is one of main reason that result in the “hot”. Usually, if there is something blocked in the evaporator inlet, then the cold air cannot blow evenly and result in the freezer in the roof of cargoes. 

In one hand, it also can result in the temperature increase in some part of truck body. In other hand, some of the vehicle refrigeration units have the defrost device, when the inlet is blocked, the 
transport refrigeration units evaporator pipe will be frozen quickly, and the vehicle refrigeration units will turn on the defrost device automatically, and then when the temperature is up to set temp, defrost device will end, and this circle will start again and again. And it will give the condition that the vehicle refrigeration units defrost frequently. 

How do you Solve the Vehicle Refrigeration Units not Refrigerating Problem? 


So in order to keep a better refrigerating effect, do not block the evaporator inlet, the cargoes should not pack too high to block the inlet. When upload cargoes, leave at least 225mm height between the roof of cargo and the roof of truck body, and cargo height is not higher than evaporator inlet height. 

Besides that, keep the truck body clean, do not leave paper scrap or packing paper, because the
 refrigeration units for trucks evaporator fans will intake the paper or scrap, then lots of dust will attached to the evaporator pipe, decrease the heat exchange rate, and the refrigerating system will not work well. 

How to Use Truck Refrigeration System Transport Cargo Better?

In order to keep the frozen foods fresh and decrease the food damage, it needs to be in the low temperature all the time after it manufactures, transports and delivers to customers. So how to make your truck refrigeration system in a proper situation and finish this frozen transport ideally? Let’s see this article to get more tips! 
1.Cooperate the truck refrigeration system properly 
The 
truck refrigeration is one of the most important equipment in a reefer truck, so to know how to cooperate the truck refrigeration unit rightly is the key to keep frozen cargoes safe, especially for the long distance transport refrigeration unit, drivers need to pay more attention to the truck refrigeration and transportation. 
2.Preventive maintenance of the truck refrigeration system and trucks 
Preventive maintenance can decrease the repair and cooperation cost and increase the 
truck refrigeration working life. Usually, the truck engine needs to be maintained after 10000km, and the truck refrigeration system needs to be maintained after 500-700 hours working. Take Guchen Thermo truck refrigeration system as example, after 500-700h working hours, it need to be oil filter, fuel filter and air filter; check the belt and whether refrigeration system leakage.
3.Suitable package is the key to protect frozen cargoes
For the frozen cargoes, it needs airless package, and for the fresh cargoes, it needs ventilated package. What’s more, all the package needs to be pressure proof. 
4.Precool or preheat before upload frozen cargoes
Before upload the frozen cargoes, please turn on the
 truck refrigeration system and set the required temperature, precool or preheat for 1.5 hours, and then turn off the truck refrigeration, upload cargoes fast. 

Tip: Why Precool or Preheat is Important When Upload Frozen Cargoes? 
5.Check the cargoes temperature when cargoes are uploaded in the refrigerated trucks 
It seems that there is a common mistake that most people may make, people always think that the 
truck refrigeration system can decrease or increase the cargoes temperature to the required temperature. In fact, the truck refrigeration is used to keep the cargoes temperature not decrease or increase cargoes temperature. 

Tips: Why Needs to Turn off Truck Refrigeration System When Upload Cargoes? 

6.Do not put the cargoes in the truck refrigeration evaporator inlet

Usually, the airless in the refrigerated truck body is main reason that result in cargoes damage, in fact, any block materials around cargoes may result in “hot”. So when upload cargoes, carefully check whether the cargoes block the truck refrigeration evaporator inlet. Keep the cargoes height is lower than truck refrigeration evaporator inlet height. If not, it will effect the temperature and even effect the truck refrigeration system working.

Tips: 
Why Your Truck Refrigeration System is not Refrigerating? 
7.Keep the refrigerated truck body clean
Clean the truck body, and do not leave packing paper or paper scrap in truck, because it will block air flow or intake by evaporator, then effect the refrigerating system. For long time, the more impurity will be attached to the evaporator tube, and decrease the heat exchange rate. That is why some drivers think that their
 truck refrigeration units not refrigerating better than before. 

To conclusion, keep the perishable food fresh and high quality is the main purpose of frozen food transportation, and keep low temperature condition is core, so it needs more attention and investment. So the first step for the truck drivers is use 
vehicle refrigeration system correctly and it is also the key point to keep cargoes quality.

Why Needs to Turn off Truck Refrigeration Unit When Upload Cargoes?

Some smart tips that drivers should to know when they cooperate the truck refrigeration unit during the frozen transport business, for example, turn off the truck reefer unit when upload the cargoes, let’s see why should do this.

It’s know to us all that before upload cargoes, it needs to be precool or preheat for 1.5 hours in order to keep the cargoes fresh, but few people to know it should turn off the
refrigeration units for trucks when upload the cargoes. So why should do this? 

Reason: when after precool truck body to the required temperature, if the 
truck refrigeration unit is still on, and the evaporator fans are still working, the front side is positive pressure and the back side is negative pressure, so the cold air will blow from the roof of truck body, and intake much hot air into the down side of truck body, which result in the temperature is up quickly; if turn off the refrigeration units for trucks, and then upload cargoes, evaporator fans are not working, and air flow stops, the pressure is same between outside and inside of the truck body, so the outside hot air is intaken into the truck body slowly.

How to Select Suitable Refrigerated Trucks for your Business?

Refrigerated trucks included into refrigerated trailers with its truck refrigeration units mounted on truck back and small to large refrigerated trucks with its truck reefer units front mounted on the truck head. Usually, if for the downtown or countryside frozen transportation with not too much cargoes , choose light reefer trucks and if for the long distance cold chain transportation with too much cargoes, it is suitable to choose heave reefer trucks or refrigerated trailers. Whether a refrigerated trucks have a good or not working performance, it is mainly because of its chassis, truck bodies and truck refrigeration units, when these three parts are better in performance, and then the whole transportation will have a reliable and stable service. 

1.Choose the Right Truck Chassis

Compared with original truck chassis, when choose refrigerated trucks, it should take the chassis stability into consideration especially, because the cargoes should be delivered to destination on time or it will goes bad. Refrigerated cargoes have a higher requirement to transportation environment, if trucks drop on the half way, it may result in cargoes going bad and loss. So for the short distance transportation, choose light truck chassis, and long distance transportation or large cargoes, choose the heave truck chassis or trailer chassis. In conclusion, when choose truck chassis, cargoes weight, road condition and personal purchasing power should be into consideration. 




2.Choose the Better Thermal Insulation Truck Bodies
Compared with general truck bodies, the refrigerated truck bodies should have the high quality thermal insulation performance to keep refrigerated cargoes in a fixed temperature. It is closed to what cargoes need to transport when choose refrigerated truck bodies, for example, it need to equip with a customized hook for fresh meat transport; if deliver cargoes for shop or store, for example, various in cargoes and little in numbers, it needs muti-temp truck refrigeration units; if need to load and upload frequently, it need muti-doors refrigerated truck bodies. Users can customize refrigerated truck bodies in truck body factory. Of course, Guchen Thermo manufactures truck refrigeration units for years, and also have a good relationship with domestics truck body factory , we can help customers to find the best truck body supplier in China with high quality and low price. 



3.Choose Diesel Engine Powered or Vehicle Engine Powered Truck Refrigeration Units?
Vehicle engine powered truck reefer units are common units that we usually see in road, it has low price, easy to maintain, but it doesn’t have a power device itself, so it needs to rely on vehicle engine driving compressor to get power, affected by engine. Diesel engine
 truck refrigeration units have its own electric generator device for the whole refrigerating system working, not rely on vehicle engine, and have a reliable performance, but high price. Usually to recommend that, urban or countryside short distance transportation and truck bodies length is shorter in 7 meter, vehicle powered refrigeration units for trucks are suitable; if for long distance transport, and truck bodies length is longer in 7 meter, the diesel engine powered is suitable.
