Side air blowing method for air-cooling type refrigerator and air-cooling type refrigerator employing the method

Abstract

The invention relates to a side wind feeding method of wind cold refrigerator and relative refrigerator, wherein said method sets the wind feeding open and the reflux wind open at the upper part and bottom part of the same side wall, to blow out the cold wind at the top of side wall to feedback via the reflux open; and the refrigerator comprises a force wind cycle refrigerating system, which is characterized in that: the wind feeding open and the reflux open are arranged at same wall, while the wind feeding open is at the top and the reflux open is at the bottom. The invention can form large reflux area in refrigerator, to improve the refrigerating effect of the food at the bottom, and release cold to the food. The refrigerator has high energy / efficiency ratio and small occupied space,

Description

technical field [0001] The invention relates to an air supply method for an air-cooled refrigerator and an air-cooled refrigerator. Background technique [0002] Today, most of the freezers that use vapor compression refrigeration are direct cooling. The cold air cools the food by natural convection. The evaporator is generally installed in the side wall or / and bottom wall of the freezer. The refrigeration system mainly includes compressors, condensers The working process is: the refrigerant liquid in the evaporator absorbs the heat in the freezer at low pressure and low temperature and boils, and the low-pressure and low-temperature refrigerant vapor generated is compressed Inhaled by the machine, after being compressed, it becomes a high-pressure and high-temperature gas and enters the condenser. Due to the cooling effect of the outdoor air, the refrigerant releases heat in the condenser and condenses into a liquid for the outdoor air. Then it returns to the evaporator, a...

Problems solved by technology

However, in this way, since the air supply and return air outlets are arranged relatively on the top of the two side walls, the air distribution method of upward air supply and upper air return makes the cooling effect of the cold air on the food at the bottom of the freezer poor, especially when the amount of food is stored. When it is relatively small, this problem is even more prominent, and in order to improve the cooling effect of the food at the bottom, the refrigeration system has to run for more time to fully cool the food at the bottom, so the energy efficiency ratio of the freezer will be reduced

Although this invention makes the top cover a top cover with a large concave space on the side of the cold room in order to reduce the cooling loss and improve the cooling effect of the cold room, the cooling effect of the food at the bottom is limited. It takes up a lot of space. Compared with the same capacity freezer, this type of freezer takes up a lot of space overall
