Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of refrigeration, specifically relates to a refrigeration appliance. BACKGROUND

[0002] The heat preservation technology of the household refrigeration appliance is a key technology to ensure the stability of the internal temperature of the refrigerator and reduce the loss of cold quantity. Due to the problems such as aging or damage of the door seal, frequent opening and closing of the door, improper temperature control setting, and the like, the heat preservation effect of the refrigeration appliance will become worse and worse over time. The common heat preservation technologies of the refrigerator such as the multi-layer heat preservation material, the intelligent door seal, the double-layer door design, and the like have a high cost, and also cannot effectively reduce the loss of cold quantity of the door body of the refrigerator, which seriously affects the energy efficiency and the fresh-keeping effect of the refrigerator.

[0003] Wind pressure insulation is a technology in building and equipment design, aiming to improve the insulation effect by using wind pressure. Wind pressure insulation design can form an air flow path to generate air flow by natural wind pressure or mechanical ventilation system, and carry away the heat on the surface of the building or equipment, thereby reducing heat conduction. This way not only helps to reduce the temperature inside the building, but also reduces the load of the air conditioning system, achieving the effect of energy saving and emission reduction. The air curtain heat preservation is a technology that uses an air curtain (also known as an air curtain machine) to insulate external cold or hot air from entering the indoor space, thereby achieving the effect of heat preservation. The air curtain machine is usually installed at the entrance of the hall, store, industrial gate, etc., and forms an "air barrier" by high-speed air flow, which prevents direct exchange of indoor and outdoor air. The air curtain heat preservation can insulate the exchange of cold and hot air, maintain the stability of the indoor temperature, reduce the load of the equipment, reduce energy consumption, and prevent external dust and pollutants from entering. The air curtain product is suitable for various places such as commercial buildings, industrial plants, supermarkets, and restaurants. The air curtain technology can effectively improve the heat preservation effect, but it is less used in household refrigeration appliances, and has a low degree of combination with the refrigeration system.
