Consumers who buy upright cooler cannot be tempted by the gorgeous appearance. Function, performance is the most important. The current vertical cooler is not a food refrigerator in the traditional sense, but the core function is to keep fresh. The second is to observe the freezing force of the vertical cooler. The food stored in the refrigerator must keep the air clean and fresh, so the cooling effect is one of the test indicators.

Determine whether the cooling effect is normal. Mainly check the temperature of the cabinet, so if the temperature of the vertical cooler meets the requirements of the specification, the vertical cooler is normal.


1. There is no part of the evaporation tube in the manufacturing process of the vertical cooler, so the part here may not be frosted. The temperature in the cabinet is transferred in stages. After working for a period of time, the temperature difference in the equilibrium state is not large, so there is no part The frost or frosted part is used as a criterion for judging the cooling effect of the vertical cooler. It is also important that the user is familiar with the correct use of the vertical cooler.


2. Consumers who buy upright cooler also care about an index. That is energy consumption. The purchased freezer consumes more electricity, which will not only waste resources, but also increase the burden on consumers' electricity bills.


3. Choose the volume of the vertical cooler according to the actual situation of consumers, not the bigger the better, but the practicality is the most important.





Vertical cooler option steps:


1. Just like choosing other products, you must shop around. Only by comparing which vertical cooler can you know which vertical cooler is best for you.


2. Confirm the quality of the door seal of the vertical cooler. The quality of the door seal will affect the power consumption and heat preservation effect of the vertical cooler, and the service life of the refrigeration compressor.


3. It is also a very important reference factor to examine the preservation effect of upright cooler.


4. Brand selection: usually an expression of product quality and reliability. Wise consumers according to their needs, the brand reflects the comprehensive level of an enterprise.


Choose the vertical cooler from the perspective of cost performance. Low energy consumption, environmental protection, and economical. In addition to the one-time investment of thousands of yuan when purchasing the vertical cooler. This is mainly electricity and maintenance costs. Consumers must fully consider both before buying.

The enterprise users who use the refrigerator are more concerned about the use cost. Xiaobian thinks that only from the aspect of saving energy, can we effectively save the use cost of the enterprise. In the process of operating the refrigerator, if the equipment has serious failure, it will threaten the safety and stability of the equipment. In order to use the refrigerator better, enterprises need to master the skills of saving energy consumption of various equipment. The more skills players master, the more experience they have in using the refrigerator, so as to provide favorable conditions for low-cost uninterrupted operation of the refrigerator. The stronger the enterprise's awareness of protecting the refrigerator, the lower the probability of equipment failure.

The use of the refrigerator needs to avoid excessive energy consumption of the equipment. In order to better run the refrigerator and achieve the purpose of rapidly reducing the space temperature, the enterprise needs to carry out serious inspection on the equipment on a regular basis. Most of the equipment faults are small faults at the beginning, if there is no rapid treatment for small faults, when the scope of fault continues to expand, the operation safety and stability of the equipment will be seriously affected. As long as the equipment can keep stable operation, it can avoid the waste of valuable resources. Small series to introduce the refrigerator to achieve low-cost operation method.

1. Control the running power of the equipment. The energy consumption of the equipment is directly related to the operating power of the equipment. If the operation power of the equipment is high, and the equipment is not affected by any fault in the operation process, then the equipment will not have any problems in the use process. On the contrary, if the equipment fails in long-term operation, and the enterprise does not deal with it quickly in time, then the failure will inevitably threaten the normal use of the equipment. Even if the fault is relatively simple, it will also cause the enterprise to consume a higher cost to keep the equipment running.

2. Keep away from equipment failure, can extend the service life of the equipment at the same time, continuously improve the operation safety and stability of the equipment. Usually, there are signs before the equipment failure, which can timely determine whether there is a fault in the refrigerator, and make a treatment plan, so as to maintain the normal use of the equipment, and will not cause energy explosion due to the existence of the fault.

3. Test the equipment regularly. In order to ensure the safe use of refrigerators in enterprises, after more than two years of operation, enterprises need to carry out fault detection for refrigerators regularly. The lower the failure probability of the refrigerator, the less energy the enterprise consumes to run the refrigerator, so as to realize the purpose of low-cost operation of the refrigerator, which is conducive to the long-term use of the refrigerator.

To sum up, we can understand that if the equipment fails, it will inevitably threaten the use of the equipment. In order to reduce the energy consumption of the refrigerator, Xiaobian thinks that it is necessary to eliminate common faults in time and provide high-quality operating environment for the equipment. The better the operating environment of equipment, the lower the probability of equipment failure, so as to create a high-quality low-temperature environment for enterprises.



How to realize low cost operation of refrigerator? | cheap chiller fridges

Take a look at the thermostat from Upright Freezer. The freezer temperature regulator is installed in the Upright Freezer, and the temperature does not reach the temperature required by the temperature regulator. If the compressor does not shut down day and night, the freezer will cause the extreme refrigerant temperature of the refrigerant. Most of this phenomenon occurs in air-cooled refrigerator compartment refrigerators. Because the evaporator defroster of the refrigerator compartment is broken, the ice is blocked. The cooling fan is broken, or there are too many things in the freezer, the outlet is blocked, and the reason for the poor cooling effect cannot be ruled out.



You can verify whether the power connection is correct, check whether the lights in the freezer are normal, or you can further test with an electric pen. If the power connection is normal, you can monitor whether the compressor is working properly. The compressor makes a slight motor vibration during normal operation. The high-pressure output buffer pipe in the compressor is damaged or the screw fixing this pipe is loose. The high-pressure pipe does not discharge air, and the low-pressure pipe does not suck air. Therefore, the compressor works but cannot be cooled.





The compressor is working normally, you can check whether the refrigerant is used up in the cooling system. After the freezer runs for about 3-5 minutes, the power supply can be cut off and you can hear the sound of water flow. If there is no sound. Indicates that the refrigerant in the refrigeration system is exhausted or leaking. The compressor may lose its working capacity.



Solution: If there is a system leak, usually find the leaking part of the system, weld, pressure test, and add the refrigerant to a certain amount within an appropriate time to make the evaporator frost or the freezer to reach the rated temperature.

        First, there is less air-conditioning. The matched unit power is about 30% to 40% less. Usually 1.0 cubic Upright Freezer matches with 1/2HP compressor, but the compressor installed in low cost Upright Freezer is 1/3 or 3/8HP.



        Second, the cooling temperature is high. The working temperature is marked chaotically, sometimes marked as 0 degrees. The user actually reflects the summer freezing room temperature between 8 degrees and 12 degrees. This brings safety risks to food preservation that requires a constant low temperature environment.

The third cooling rate is slow.



　　 Low-cost Upright Freezer's compressor has low power, which is suitable for reducing the condenser area, condenser fan power and air volume, and evaporator area of ​​the system. Less refrigeration, slow refrigeration, only used in winter, spring, autumn, or only used in the northern region, means that it can be roughly coped with. On the contrary, this Upright Freezer has high temperature during the day or night in summer, or contains a lot of food, and the food turnover is large. The temperature of the Upright Freezer is low, and the hygiene and safety of the stored food cannot be guaranteed.



        The above is related to performance, so is there anything else in the performance of the bad Upright Freezer? Of course there are, such as service life and later expenditures.



       Upright Freezer Life: The low price Upright Freezer with inferior structure does not have any steel frame. The door frame is assembled after the cabinet body is foamed. This Upright Freezer is difficult to move multiple times. The door frame will fall off within a few years and is difficult to repair. Low-quality and low-cost Upright Freezer cabinets are selected for low-quality materials. If the materials are cheap, replace them with stainless steel or aluminum plates, copper pipes with aluminum pipes or composite steel pipes, and ABS engineering plastics with ordinary plastics. The material of Upright Freezer is so thick and thin, and copper becomes iron, its performance and service life are also reasonable.



        Expenses after use: I saved a little when I didn't buy the Upright Freezer, but continued to spend more money after years of use. First of all, because Upright Freezer has been used continuously for many years, the electricity bill is quite high. The power consumption is mainly reflected in the thermal insulation performance of Upright Freezer.

1. Upright Freezer's cooling performance



The performance of refrigeration is mainly based on the comprehensive evaluation of the refrigeration effect and cooling speed of the freezer. As long as these two aspects can meet certain standards, it can be regarded as a freezer with better refrigeration performance, just like if we store it in a freezer. When there is a lot of food, you can observe the refrigeration effect of the freezer to see how long the food in the freezer can achieve the effect of low-temperature preservation. The vertical freezer has the advantage that it is helpful for us to store food, and it is better to choose the suitable one. The temperature range preserves our food. Today's refrigerators will use vertical microcomputer temperature control technology and electronic microcomputer-designed temperature controllers. The temperature controller can automatically adjust the overall temperature of the refrigerator to ensure the freshness and safety of the food stored in the refrigerator. .

2. Understand the energy saving of freezer



The power consumption of refrigerators is a problem that many businesses who need refrigerators will consider. They will give priority to some low-energy refrigerators. In fact, I tell everyone that it is not necessarily a low-energy refrigerator that we use is good. I also need to use it according to our own The actual demand. Although some refrigerators have relatively low energy consumption, their power is also relatively small. If we want to store more food when we use it, the power of the refrigerator will not meet the requirements and the cooling requirements , Affect our use, when we choose the freezer, we should not deliberately pursue the lowest power consumption of the freezer, so as not to affect our use.



3. The design of the freezer



At present, when people buy freezers, they actually see the overall appearance of the freezer at first glance to see if the appearance can meet our requirements. Especially commercial freezers are used in supermarkets and convenience stores with a relatively large flow of people. Locally, the aesthetic appearance is very important, but the practicality of the freezer must also be considered, and whether the raw materials used in the freezer can be durable and corrosion-resistant.
