Temperature control method for refrigerating and freezing equipment and refrigerating and freezing equipment

Abstract

The invention provides a temperature control method for refrigerating and freezing equipment and the refrigerating and freezing equipment. The temperature control method comprises the steps that an actual temperature of an airtight space is detected; whether an actual temperature value is higher than or equal to a preset first temperature value or not is judged; if yes, whether an air compressor is at work or not is detected, and when the air compressor is not at work, a switching mechanism is driven to enable an airflow pipeline between the air compressor and the airtight space to communicate and to close an airflow pipeline between the air compressor and an adsorption bed assembly; and the air compressor is controlled to operate at a preset first rotating speed so as to inject sucked low-temperature air into the airtight space to lower the temperature of the airtight space. By adoption of the scheme, the airtightness of the airtight space is ensured, the temperature in the airtight space can be precisely adjusted, and the storage effect of food is improved.

Description

technical field [0001] The invention relates to the field of item storage, in particular to a temperature control method for refrigerating and freezing equipment and the refrigerating and freezing equipment. Background technique [0002] With the development of society and the improvement of people's living standards, and people's pace of life is getting faster and faster, people often buy a large number of items placed in various refrigeration and freezing equipment, but for leafy vegetables and melon and fruit foods, refrigeration and freezing The low temperature in the appliance's storage compartment will not only wrinkle and blotch the skin of these foods, but also affect their original taste and nutrition. [0003] Nitrogen, as a colorless, non-toxic, odorless inert gas, has been widely used in the field of food preservation. Filling the storage compartment of refrigeration and freezing equipment with nitrogen to balance the carbon dioxide and oxygen in it can effective...

Problems solved by technology

[0004] In the prior art, a sealed space is often set in the storage room as a fresh-keeping room. In order to ensure the fresh-keeping effect in the sealed space, the airtightness of the sealed space is higher, which also makes the temperature in the sealed space unable to be adjusted through the damper. , and the cold energy can only be transferred to the sealed space through the low temperature of the refrigerated compartment

This method of lowering the temperature makes the temperature of the sealed space drop slowly, and the temperature cannot be adjusted accurately, which affects the storage effect of food in the sealed space, thereby reducing the user experience
