Problems solved by technology

Increasing the thickness of the foam layer will reduce the available volume of the compartment and increase the cost; allowing a part of the condenser tube to pass through the side plate of the box will result in a more complicated design and greater difficulty in production; adding a heating device will increase power consumption

Abstract

The invention relates to a cold storage and refrigeration device. The device comprises a box body, a machine room is arranged on the lower portion of the rear side of the box body, a compressor used for compressing refrigerants and a condenser used for carrying out heat exchange with air are contained in the machine room, the machine room is provided with an air inlet and an air outlet which are used for allowing the air flow to circulate between the air inlet / the air outlet and the exterior environment, at least one first box body exhaust channel is formed in a side plate of the box body, each first box body exhaust channel is directly or indirectly communicated with the air outlet of the machine room or an air outlet area adjacent to the air outlet, and therefore at least part of hot airflow generated in the machine room is guided into the first box body exhaust channels; heat in the part of hot airflow can be sufficiently used for improving the temperature of the side plate of the box body; heat in the machine room can be sufficiently used, condensation generated by the side plate of the box body can be effectively prevented, and meanwhile, the device is simple in structure and easy to obtain.

Description

technical field [0001] The invention relates to refrigeration and freezing storage technology, in particular to a refrigeration and freezing device. Background technique [0002] Most of the evaporators and refrigeration pipelines of existing refrigerators are in the foam layer of the box body. When the pipeline is displaced and close to the outside of the box, the cold energy will also be transferred to the outside of the box. Because the air in the environment has a certain humidity, when the temperature outside the refrigerator box reaches the dew point temperature, condensation will appear on the box, especially in the case of excessive air humidity such as thunderstorms in summer, the condensation phenomenon will be more severe. serious. Flowing water appears on the cabinet, which not only affects the user's use, but also may cause the risk of electric shock in severe cases. [0003] The methods for preventing condensation on the side panels of existing refrigerators...
