Environmental protection refrigeration equipment takes environmental protection as the theme and has functions such as rapid refrigeration, quick freezing, and cold storage. Vertical freezers, refrigerated cake display cabinets, and deep-freezing horizontal cabinets in shopping malls are all unified as refrigeration equipment.
The core elements of refrigeration are energy, medium, and carrier. Energy is indispensable for refrigeration equipment including refrigerators and freezers. It is “electricity”. Without electricity as the source of power, no matter how good the equipment is, it will not operate. The power consumption of various equipment on the market is also different. There are many influencing factors. The indoor and outdoor temperature difference and the number of door openings and closings are the main ones. Secondly, the sealing performance of the box and the insulation effect of the material. No matter which aspect is not good, it will bring greater power consumption.
The medium is one of the cores of refrigeration equipment and also an important material for environmental protection. We all know that the medium for refrigeration equipment such as cake cabinets and beverage cabinets is refrigerant, such as R134a, R600, and R152/R22. Some old ones have been eliminated. Different equipment uses different types of media.
Therefore, it needs to be determined with the manufacturer when choosing.
Compressors, condensers, etc. are important carriers of refrigeration equipment. Refrigerators achieve refrigeration through the cyclic flow of refrigerant. The refrigerant becomes a high-temperature and high-pressure gas under the action of the compressor. After being cooled and liquefied by the condenser, it is depressurized through the expansion valve and enters the evaporator to vaporize and absorb heat, reducing the internal temperature and completing the cycle.
Different refrigeration equipment needs to pay attention to matters in the use process, understand the importance of selection, the professionalism of maintenance, and the timely solution of faults.
(1) How to choose commercial refrigeration equipment requires skills
For refrigerated equipment, such as cake cabinets and beverage cabinets, this requires considering aspects such as the refrigeration effect, capacity size, energy consumption level, brand reputation, and after-sales service of the refrigeration equipment. These factors combined are the skills for choosing commercial refrigeration equipment.
(2) Professionalism of refrigeration cabinet maintenance
The professional degree shown when performing maintenance work on the refrigeration cabinet, including possessing professional knowledge and skills, understanding the working principle, structural composition, and common fault types of the refrigeration cabinet, and being able to accurately judge the problems that occur in the refrigeration cabinet and take appropriate maintenance measures.
For example, professional maintenance personnel can skillfully conduct detection and repair of the refrigeration system, conduct safety inspections and troubleshooting of the electrical part, and can also regularly clean and maintain the refrigeration cabinet to ensure that it is always in a good working state and prolong the service life of the refrigeration cabinet.
(3) Timely solution of freezer faults
When a freezer malfunctions, measures should be taken quickly and promptly to deal with it to ensure that the freezer can resume normal operation as soon as possible. For example, once faults such as non-refrigeration and abnormal temperature are found in the freezer, relevant personnel should immediately conduct inspection and repair without delay to avoid affecting the storage quality and safety of items in the freezer.
What are the usage skills of commercial refrigerated display cabinets?
What are the methods that can better play its role and improve the use effect during the use of display cabinets. For example, it may include skills in aspects such as reasonable adjustment of temperature, placement of items, and regular cleaning and maintenance.
1. Reasonably adjust the indoor temperature
Too high or too low temperature will affect the beauty and safety of food. Regularly monitor the temperature and ensure that it operates within the optimal range (such as 25℃ ± 10%).
2. Way of placing food
In terms of the arrangement order, direction, and spacing of food items. For example, items can be neatly arranged in a row or stacked together; they can be classified and placed according to characteristics such as size and color; or the placement position of items can be determined according to usage frequency or importance. Different placement methods will affect space utilization efficiency, aesthetics, and the ease of taking items.
3. Defrosting treatment skills
If it is an old refrigerated display cabinet, there will be a frosting problem during use. You can place a basin of warm water at 40-50℃ in the cabinet to accelerate defrosting. Use a soft plastic shovel (avoid scratching the inner wall with metal tools) to gently remove the loosened frost blocks, and then absorb the moisture with a dry cloth. Note that the power should be cut off during this operation.
At present, newenll indicates that many refrigerators are equipped with an automatic defrosting function, but it is only limited to direct-cooling types. For air-cooled types, there is also automatic defrosting. Different brands use different defrosting methods, but the principle is through heating.
4. Oil stain or sticky stain cleaning skills
Some freezers will inevitably have oil stains when placed in the kitchen. Use white vinegar or 5% concentration of baking soda water for wet compress for 5 minutes and then wipe. This can clean well. Do not use steel wool or hard utensils to scrub, as this will damage the cabinet body.
Using 75% concentration alcohol for disinfection has the best effect. Mainly, alcohol is volatile and there will be no residue after disinfection. If you find an odor in the refrigerator, using activated carbon or lemon slices is excellent. Pay attention to ventilation is very important.
Of course, an important detail cannot be ignored. After using the display cabinet for half a year, check the sealing strip. Especially for frequent use in shopping mall environments, it will lead to deformation and cracking, resulting in poor insulation effect and increased energy consumption. In addition, mold and bacteria are easy to grow near the sealing strip. This is because it is at the junction of hot and cold, resulting in frequent humidity and a slightly higher external temperature, which is also conducive to mold growth. Pay attention to cleaning and disinfecting weekly. In some small shopping malls, there are many such problems.
Special reminder, avoid chlorine-containing bleach and strong acid and strong alkali cleaners during daily maintenance and cleaning. Wear gloves during cleaning to prevent low-temperature frostbite or skin irritation from cleaners.
The above are the matters that need attention and small maintenance tips during use. Failure to perform maintenance will increase the frequency of failures, increase energy consumption, and reduce the service life of the display cabinet.
How to choose a household display cabinet?
Choosing a household display cabinet needs to meet actual needs. Look at the usage purpose. For deep freezing needs, such as for meat, etc., choosing a small horizontal display cabinet is cost-effective because ordinary households do not need a large-capacity quick-freezing cabinet and can save costs.
For household food storage of fruits and vegetables, a household multi-storage area refrigerator is a good choice. Household refrigerators are divided into many storage areas, which is convenient for classified storage of food. There are also different settings for temperature areas. The refrigerated area is placed on the upper layer, and the quick-freezing area is placed on the lower layer.
With economic development and the improvement of users’ living standards, self-driving tours have become the choice of more and more people. A household mini display cabinet is a must. It has a capacity of 40-60L and can refrigerate beverages and food that needs to be refrigerated. It is simply a “mobile refrigerator”. When you are in a hot and thirsty environment during the journey, this “small refrigerator” will bring you an ultimate experience. A bottle of cool beverage will make you feel happy.
How to choose a cake refrigerated display cabinet?
Cake is the core food for everyone’s birthday. Although it is delicious, it needs to be stored in a low-temperature environment. At this time, a refrigerated display cabinet with refrigeration function is very important. Common models include NW-RY830A/840A/850A/860A/870A/880A and other series, as well as NW-ST730V/740V/750V/760V/770V/780V series. The difference between these two types is the corner. The NW-RY series uses curved glass panels, and the NW-ST series uses right-angle glass panels. They all have a refrigeration function of 2-8 degrees, and there are different choices of volume and capacity. For large-scale cake shops, shopping malls, etc., large-sized types of 2400*690*1600mm can be used, which have greater capacity and space. There are mobile casters at the bottom, which is very convenient. If the sales volume is not large, a small 900*690*1600mm cake cabinet is definitely sufficient.
Selection needs to be based on size, style, and price:
(1) Size
In terms of size, the factory will provide commonly used types. For example, lengths of 900mm/1200mm/1500mm/1800mm/2100mm/2400mm are all set in existing drawings. There are 2/3/4 common shelf layers.
(2) Style
Different styles of display cabinets bring different user experiences, especially cake display cabinets. In addition to the common types with arcs and right angles, there are also French styles and American styles. For custom unique styles such as cabinet stickers and lighting design.
(3) Price
What is the level of price? On the one hand, it is related to the configuration of the display cabinet. The higher the configuration, the more expensive the price, the more comprehensive the function, and the better the usage experience. Especially, the price of customization will be much higher. Because customization requires steps such as modeling and adjusting the mold, the costs in terms of time and difficulty coefficient are very high. It is not cost-effective for single-unit customization and is suitable for batch production. If you choose an existing style, then the factory will give you the best solution.
On the other hand, the impact of import tariffs. According to data, the tariff situation in 2025 is severe. Tariffs of over 100% between the United States and China have led to price increases. The actual tariff price is higher. It is recommended to wait for the tax rate to drop for better cost performance. After all, the market will always enter a moderate stage.
How would you choose? Generally, after market research, choose multiple manufacturers to compare prices and needs and make a reasonable choice. This stage requires the accumulation of experience. In plain terms, it is to understand the price, quality, reputation, etc. of each manufacturer, and finally calculate the most cost-effective one.
Under the development of the market, refrigeration equipment is more abundant, intelligent, and environmentally friendly. This is also the fundamental direction of enterprise development. The growth of the refrigeration industry economy is inseparable from enterprise innovation and trade cooperation among countries. Environmental protection and intelligence will be the core cornerstones, bringing health, reducing energy consumption, and increasing user experience!
