What is the working principle of the chest freezer?

The principle of chest home freezer refrigeration is very simple: it involves removing heat from one area and depositing it to another area. When you transfer a cryogenic liquid near the objects you want to cool, the heat from these objects is transferred to the liquid, and the liquid evaporates and takes away the heat in the process.

You may already know that the gas heats up when compressed and cools down when the gas expands. That's why when you use it to pump air inside a tire, the bike pump feels warm and the sprayed water feels cold. The gas gets hot when it's compressed, and cools when it expands, with the help of some beautiful devices that help the chest freezer cool the items it holds.

Questions about professional purchase of chest freezers

Selection of volume: Generally, for the selection of a household freezer box type chest freezer, 60-70 liters is generally suitable, and a family of three choosing a 200 liter freezer is sufficient. However, as a merchant, when applied to convenience store operations, deli stores must use a slightly larger freezer to meet daily business needs. Usually around 1000 liters of capacity, which depends on the actual needs of merchant convenience stores.

The choice of the freezing power of the chest freezer: Whether the freezer has a large freezing capacity is a key issue that people must consider when purchasing a freezer. There is no strong freezing capacity to guarantee that the freezing speed of the freezer is slow. The largest freezer can only be a large storage room, which can only be stored in large quantities but cannot guarantee the quality of frozen food. At present, the freezing capacity of chest type freezers in the domestic market varies widely, ranging from about 25 halls to 18 kilograms, and the best products have reached 22 kilograms. Consumers must look at the product introduction carefully.

Fresh-keeping performance of chest freezers: The principle of food preservation is to inhibit the spoilage of microorganisms and the deterioration of food caused by the decomposition of enzymes. Only by controlling the temperature inside the box at a constant low temperature state can the microorganism and enzyme activities be fully inhibited , Lock the freshness and nutrition of the food. At present, there are three types of electric freezers in the market: computer temperature control, electronic temperature control and mechanical temperature control. Due to the use of advanced dual temperature and dual control technology, computer temperature control freezers can accurately measure the actual temperature in the box and provide information. It is delivered to the control center, and the entire process is fully computerized, so that the chest home freezer can always ensure a constant low temperature ring pit. The computer temperature control freezer can intelligently adjust the temperature to keep the food fresh and nutritious.

The design structure and practicality of chest freezers: Nowadays, the trend of chest home freezers is developing in the direction of multi-temperature zones and multi-doors. In addition to the usual freezing and refrigerating sections, there are ice temperature zones, rapid cooling zones, and even variable temperature zones. These functions Not only can improve the quality of food refrigeration, but also more practical and convenient when used. The multi-door freezer not only makes the freezer more luxurious, but also makes the refrigeration of food more scientific, reasonable and hygienic.

How to use the chest freezer to save power?

1.      The chest freezer should be placed in a place with low ambient temperature and good ventilation conditions. When placing the chest home freezer, proper space should be left on the top of the chest freezer and on the left and right sides to facilitate heat dissipation.

2.      Minimize the number of door openings and opening times when storing food. The opening and closing actions should be fast, the opening angle should be as small as possible, and the food should be taken out or put in at one time as much as possible, so as to avoid excessive cold air overflow and excessive indoor heat. Air enters the chest freezer.

3.      Never put hot food in a chest type freezer. Because hot food contains a relatively high amount of heat, the temperature inside the box will rise sharply when placed in a fresh-keeping cabinet, and at the same time, the thickness of frost on the surface of the evaporator will increase, the compressor's working time will be extended, and the power consumption will increase. Therefore, hot food must be cooled outside the box before being placed in a chest home freezer.

4.      The amount of food stored in the freezer should not be too full or too tight, and should be placed reasonably. Because the volume and load of the electric freezer and fresh-keeping cabinet are fixed, the food in the box is too full and too tight, which will affect the convection of the air in the box, make it difficult to radiate the food, and affect the fresh-keeping effect of the food. At the same time increase the compressor working time, so that power consumption increases.

5.      Vegetables, fruits, and other watery foods should be washed and drained before being placed in the fruit and vegetable box to reduce evaporation of water in the fruits and thicken the frost layer, shorten the defrost time and save electricity.

6.      Make ice cubes and cold drinks at night as much as possible, because the night temperature is low, which is good for the condenser to dissipate heat. At the same time, the door is not opened to pick up food at night. The compressor has a short working time and will not cause the compressor to overheat.

7.      Regularly defrost and remove dust on the surface of the condenser and the cabinet to ensure that the evaporator and condenser have good heat absorption and heat dissipation performance, shorten the working time of the compressor, and save electricity.

8.      Under the premise of ensuring the quality of food, the temperature controller is adjusted reasonably according to the seasonal changes, the type and quantity of food, so that the whole machine is always in the best working condition.
