Airflow dehumidification module applied to refrigerating and freezing device and refrigerating and freezing device

Abstract

The invention relates to an airflow dehumidification module applied to a refrigerating and freezing device and the refrigerating and freezing device. The refrigerating and freezing device is providedwith a storage chamber for storing articles. The airflow dehumidification module comprises an air inlet pipe section, a cold transfer dehumidification pipe section and an air outlet pipe section whichare sequentially communicated with each other; the air inlet pipe section is communicated with the external environment; the air outlet pipe section is communicated with the storage chamber; the coldtransfer dehumidification pipe section is provided with a pipe body and at least two phase change energy storage units which are independent from each other and are located at different positions ofthe pipe body; the cold stored in the at least two phase change energy storage units which are independent from each other is used for condensing and dehumidifying the airflow flowing from the external environment to the storage chamber more fully and thoroughly in different positions of the cold transfer dehumidification pipe section, so that the airflow flowing to the storage chamber is dry airflow; therefore, a large amount of frost generated in the refrigerating and freezing device due to introduction of high-humidity airflow is efficiently and durably prevented; the amount of the frost isreduced; and the usage experience of a user is improved.

Description

technical field [0001] The invention relates to refrigerating and freezing technology, in particular to an airflow dehumidification module used for a refrigerating and freezing device and the refrigerating and freezing device. Background technique [0002] Refrigeration and freezing devices, such as refrigerators, freezers and freezers, are common electrical equipment used to store various items that need to be refrigerated or frozen, and are widely used in households, supermarkets and other industries. After being used for a period of time, the refrigerator and freezer will form frost on its inner wall (especially the freezer, the amount of frost produced by it is more obvious). An important reason for frosting is that when the compressor is turned on and off, the pressure inside the refrigerating and freezing device changes, and the humid air from the external environment enters the inside of the refrigerating and freezing device through the door gap, and then the moisture...

Problems solved by technology

However, the problem with this method is that the desiccant in the ventilation pipe has a short service life and needs to be replaced regularly, which increases the user's cost of use; in addition, the hot air is directly introduced into the refrigerating and freezing device, which increases the energy consumption of the refrigerating and freezing device
