Some people may wonder how to choose the right freezer.
1. Look at the preservation effect. The main function of the freezer is to ensure the freshness of refrigerated food, so the freshness preservation effect is an important basis for purchasing. According to scientific analysis, in order to keep food fresh, on the one hand, it is necessary to have a constant temperature and a strong "freezing force" inside the refrigerator, and on the other hand, it is also necessary to keep the air circulation in the refrigerator clean and fresh. Because only a strong "freezing power" can effectively achieve the purpose of storing food, it is necessary to increase the freezing power of the freezer to a certain height when purchasing a refrigerator.
2. Look at the volume of the freezer. There are thousands of refrigerators, large and small, on the market. Don't listen to others saying that buying big looks majestic and making "reckless" decisions. It can be referenced according to the size of the hotel and the flow of people.
3. Look at the energy consumption of the freezer. Refrigerators are known as "electric tigers". Therefore, choosing an energy-efficient refrigerator with low power consumption is a wise move to save money in the future.
4. It is best to buy brand freezers with guaranteed quality and good after-sales service. The quality of a branded product is directly proportional to its price. Look at whether the manufacturer's product positioning is high-end or low-end; whether consumers can consider the brand, freshness, energy saving, volume, and price. , I believe you will buy the products you like.
Introduction of cooling load
The cooling load of the refrigerator is the heat that must be taken out of the refrigerator per unit time; or the cooling capacity that the refrigerator obtains from the refrigerator per unit time. The purpose of calculating the refrigeration load of the cold room is to correctly and reasonably determine the refrigeration equipment load and a mechanical load of each cold room. The cooling load of cold storage is not constant throughout the year, and its load is affected by many aspects. For example, changes in the external environment temperature, the storage capacity of food in the cold storage, the difference in the amount of cold processing of food in off-season and peak season, operation and management methods, and many other factors. Usually, the calculation of cooling load is one of the primary tasks in the design of cold storage refrigeration equipment. Therefore, refrigeration design needs to reasonably determine the refrigeration load of cold storage.
For top-loading freezers, more attention should be paid to cooling, because the same level of cooling cannot always be maintained in summer and winter.
