What you must know when choosing a supermarket freezer!
Freezer storage cabinets are one of the essential needs in people's lives. In daily life, freezer plays a very big role as kinds of food need be displayed in the freezers and refrigerators for fresh. So what issues need attention when preserving foods?
The refrigerated display cabinet adopts microcomputer automatic control, automatic constant temperature and automatic frost, to ensure the device is up and running.
All the components of the freezer display cabinet are treated with anti-corrosion and anti-rust treatment, and covered by protective coating which is sprayed by the electrostatic powder spraying process. These can effectively reduce the heat and moisture exchange between the interior of the refrigerator and the outside air, and reduce the energy consumption of the refrigerator.
1, What kinds of supermarket refrigerator are there?
Commercial freezers are divided into several categories: open air merchandiser, glass door merchandiser, island freezer, meat refrigerator, ice cream cabinets and cake cabinets, with volumes ranging from 20L to 1600L. The temperature in refrigerated cabinet is 0-10 degree celsius, which is widely used in the storage and sales of various beverages, dairy products, fruits, etc. For the frozen food, such as ice cream, seafood.. We always store and display in freezers that in -18~-22 degree celsius.
There are many types of refrigerators available on the market, such as small refrigerators, double temperature double boxes (with refrigerator and freezer), dual temperature conversion freezer (refrigerated in the same room for refrigerating), horizontal display cabinet, vertical Display cabinets, etc.
PCF combi freezer is the model that has double temperature double boxes. Goods are placed in upper and lower parts separately for easy fetching, easy choice between chiller and freezer. It enables you to use your sales space to its maximum potential and catch your customer's eye with flawless product presentation.
Horizontal display cabinet-the island chest freezer (PICF) is a champion energy-saver with an attractive panoramic view, which stands out through its smart and economical product presentation with high storage volumes.
Glass door merchandiser and open air merchandiser are the main kind of vertical display cabinets. Glass door merchandiser have its unique design of anti-fog glass door to keep goods clearly visible and neat. Open air merchandiser has forced air cooling circulation, the air curtain ensure the fast refrigerating and stable temperature.
2, Supermarket freezer, how to lower energy consumption?
The long-term working hours of supermarket freezer will increase the power consumption. The power consumption is not only related to the power of the freezer, It also has some hidden power consumption details. How to deal with it? Phirella will take you to start the power saving mode.
1. Set reasonable temperature
Do not blindly lower the temperature, adjust the temperature according to the different situations. The lower the temperature, the more energy the machine consumes and the more power it needs.
Adjust temperature of the refrigerator according to the needs of the food. In summer, temperature of the supermarket is recommended to be set to about 3℃, and the temperature of the freezer will float between 2 and 6℃. This will not only maintain the refrigeration effect of the food, but also reduce the power consumption of the refrigerator.
2. Regular defrosting
Supermarket refrigerators should be defrosted regularly. Frosting on the surface of the evaporator will reduce heat transfer efficiency and reduce the cooling effect, resulting in longer machine working hours and increased power consumption.
According to the data analysis, when the surface of the evaporator is frosted by 10 mm, the heat transfer effect is reduced by 30%, which increases the operating efficiency of the refrigeration and greatly increases the power consumption.
3. Freezer space finishing
There should be a certain gap between the food & food and food & the inner wall of the freezer to keep the air circulating in the freezer, improve the cooling effect, and reduce the number of startup times and running time of compressor. Foods that are too hot should be placed until room temperature before being placed in a freezer. Reduce the load on the freezer to avoid excessive consumption.
4. Installation location
When installing the freezer, it should be placed in where with low temperature and good ventilation. This can help the heat dissipation of the freezer and reduce the startup times and opening time of the compressor.
5. Regular cleaning
Regularly clean the dust on the condenser. If the condenser has accumulated dust for a long time, it will affect the heat dissipation of the freezer. And also it will not be effectively evaporated and affect the cooling effect. To reach the predetermined temperature, freezer needs to extend the working time of the compressor and increase the power consumption. It is best to clean every three months for a commercial freezer condenser.
As long as we use the refrigerator reasonably and pay more attention to the using method, we can reduce the wear of the compressor and prolong its service life. At the same time, this can reduce power consumption and save electricity expenses.
