Refrigeration regulating method based on environment temperature and regional pressure value

Abstract

The invention discloses a refrigeration regulating method based on an environment temperature and a regional pressure value. The method comprises the steps: acquiring a pressure value of a target region; acquiring a temperature value of the target region; and comparing the pressure value of the target region with a preset threshold value, comparing the temperature value of the target region with a preset threshold value, and regulating a cooling coefficient of the target region by combining the two comparative results to precisely regulate the cooling temperature and cooling air velocity of the target region according to the weight of food stored in the target region and the current environment temperature, so that the preservation energy consumption and the preservation cost are reduced under the condition that the quality of the stored food is kept, resource waste is avoided, a method for storing the food is made safer and more intelligent, and consumers can really eat assured meat, assured grains as well as assured fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration adjustment method based on ambient temperature and regional pressure values. Background technique [0002] People eat food every day to maintain their lives, and these foods need to go through links such as production, storage, processing, transportation, and sales before they can become consumer goods on people's tables. During the long-term storage, processing, transportation, and sales process, it is inevitable that there will be preparation, change of taste, even deterioration and rot, and it will be completely inedible. According to incomplete statistics, about 80 million tons of fruits and vegetables are spoiled and rotted in the whole country every year, accounting for more than 20% of the total production, which can be eaten by 200 million people for one year, and the economic loss is more than 750 billion yuan. The loss caused by the dama...

Problems solved by technology

[0003] Therefore, in order to reduce or save losses, people have adopted various methods to preserve food. Freezing preservation is the longest and most widely used fresh-keeping method. The disadvantages are: high energy consumption, low temperature Generally between -25°C and -30°C, during the freezing process, it takes 60-80 degrees of electricity to freeze a meal of meat, and the cooling parameters of the cold storage will not change all the year round, and cannot change with the temperature in the cold storage Adjusting with the weight of the food in the cold storage caused a great waste of resources
