About the characteristics of the freezer
Regarding the characteristics of the freezer, the refrigeration technology of the freezer is now becoming more and more perfect. The refrigeration load of the freezer cold room is not constant throughout the year. The size is affected by many aspects. Let’s take a look at the characteristics of the freezer. Characteristics of Freezer 1
Freezer is another name for refrigerator and freezer. All evaporation tubes of high-quality refrigerators are made of high-quality copper coils and processed into wide-surface special shapes. The surface of the stainless steel plate is smooth and clean, and the thickness of the entire plate is uniform. Using an appropriate thickness not only ensures a long service life, but also makes the appearance of the freezer smooth and solid. Copper pipes have better cooling effect and better corrosion resistance than aluminum pipes or composite pipes. High-quality copper coils have the advantages of high internal cleanliness and fewer pipe joints, which can effectively prevent internal leakage or blockage in the refrigeration system. By processing the circular tube into a rectangular shape, the contact between the evaporator tube and the cold-transmitting liner changes from point contact to surface contact, which expands the transmission area and speeds up the refrigeration speed.
The dual refrigeration technology of the freezer solves the technical problems that are difficult to overcome with a single refrigeration method, leaving no refrigeration blind spots in the cabinet. The 500mm ultra-wide shelf provides customers with a larger effective display area and more inventory. Osram's special light tubes placed at the front of each shelf enhance the display effect of the items inside the cabinet. The integrated foaming and solid steel frame foundation of the freezer make the cabinet better insulated and the structure more solid and durable. The corrosion-resistant color steel plate cabinet liner increases the service life of the cabinet. The fully transparent glass side panels of the freezer make the items inside the cabinet clear at a glance and enhance the display effect of the items inside the cabinet. The microcomputer-controlled digital thermostat makes the temperature control of items in the cabinet more precise and the system more energy-saving.
The refrigeration load of the freezer refrigeration room is the heat that must be taken out of the refrigeration room per unit time; or it is the cooling capacity that the refrigeration room obtains from the refrigerator per unit time. The purpose of calculating the refrigeration load of the refrigeration room is to correctly and reasonably determine the cooling equipment load and mechanical load of each cold room. The cooling load of the cold room is not constant throughout the year, and its load size is affected by many aspects. For example, changes in the external ambient temperature, the amount of food stored in the cold room, the difference in the amount of cold processing of food in the off-season and peak season, and many factors in the operation and management methods, usually the refrigeration load calculation is the initial work of designing the cold storage refrigeration device. one. Therefore, reasonably determining the refrigeration load of the cold room is very important for refrigeration design.
When calculating the refrigeration load of a refrigerator, the most unfavorable working conditions should be considered. This is the principle of outdoor computing. For rooms that transfer heat from indoors to outdoors, the outdoor temperature in hot seasons should be considered; while for rooms that transfer heat from outdoors to indoors, the outdoor temperature in cold seasons should be considered. The cold rooms of cold storage are mostly of the type that transfer heat from indoors to outdoors. Characteristics of the Freezer 2
What are the features of the Freezer?
Freezers are now very important electrical equipment. They are often used to refrigerate and store food. However, we also need to pay more attention to some points when using them in order to use them better.
1. Before storing food in the freezer, if it is empty, it must be turned on and run for 2 hours. After the temperature of the freezer reaches a stable level, the food can be stored in the freezer.
2. If the food stored in the freezer is hot, such as the hot meal you just finished eating, you should wait until it gets cold outside before storing it in the freezer. Otherwise, it will not only consume more of the freezer. The power will also affect the taste of the dishes.
3. The food stored in the freezer should not be too full or too tight, so as to extend the service life of the freezer and save electricity.
4. Ice cream, fish and other animal fat foods should be stored in the freezer compartment of the freezer, not near the door.
5. Food stored in the freezer should not be mixed with raw and cooked food to maintain hygiene.
6. Do not place food directly on the surface of the freezer evaporator, but place it in a container.
How to save power in the freezer
1. The freezer should be placed in a place with lower indoor temperature and better ventilation, which is beneficial to the heat dissipation of the freezer. It can reduce the number of starts and start-up time of the refrigerator compressor.
2. Food must be cooled to room temperature before being put into the freezer. At the same time, try to minimize the number of times the vertical refrigerator opens the door and shorten the opening time.
3. There should be a certain gap between the food in the freezer and between the food and the inner wall of the freezer to allow the air in the freezer to circulate, improve the refrigeration effect, and reduce the number of compressor starts and time.
4. Defrost regularly. When the frost thickness in the freezer exceeds 5mm, the refrigeration effect will become worse, and the working time of the compressor will be extended, so the power consumption will be relatively increased.
5. When the weather gets warmer and the room temperature reaches above 15°C, the energy-saving defrost switch of the display freezer should be turned to the off position, which can also reduce power consumption.
6. Correctly adjust the temperature controller of the freezer to reduce power consumption. The temperature control knobs of the freezer are marked with numbers, which represent the control range of the temperature inside the freezer. The smaller the marked number, the higher the control temperature. The indication range of the thermostat in different seasons is: 3 to 4 in summer; 2 to 3 in spring and autumn; 4 to 5 in winter. When the room temperature is lower than 10°C, the thermostat should be set to the "6" position.
7. Clean the dust on the condenser regularly. If dust accumulates in the condenser for a long time, it will affect the heat dissipation of the refrigerator, and it will not be able to evaporate effectively and affect the refrigeration effect. In order for the refrigerator to reach the predetermined temperature, the working time of the compressor needs to be extended, which increases power consumption. Therefore, it is best to clean the condenser every two years.
