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

Embodiment Construction

[0027] refer to figure 1 , a refrigeration adjustment method based on ambient temperature and regional pressure values ​​proposed by the present invention, including:

[0028] Step S1, collecting the pressure value of the target area, the target area includes n sub-areas, where n≥2, specifically including: collecting the pressure value of the target area through i pressure sensors;

[0029] When i=1, the pressure value of this pressure sensor is the pressure value of the target area;

[0030] When i>1, the average value of the pressure values ​​of the i pressure sensors is the pressure value of the target area.

[0031] In the specific scheme, the pressure value of the target area is collected through the preset pressure sensor, and the pressure value is the weight of the stored food. In order to ensure the accuracy of the measurement, multiple pressure sensors can be selected to obtain the pressure value of the target area. When i pressure sensors are selected, the average ...

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...
