Wet film humidifying system of air-cooling refrigerator

Abstract

The invention provides a wet film humidifying system of an air-cooling refrigerator and belongs to the technical field of refrigeration equipment. The wet film humidifying system of the air-cooling refrigerator solves the problems that according to an existing refrigeration humidifying scheme, devices are additionally arranged, more space is occupied, cost is improved, and humidity control cannot be achieved; or an external water source needs to be additionally arranged and use is inconvenient. The wet film humidifying system of the air-cooling refrigerator comprises a freezing chamber and a refrigerating chamber, the freezing chamber and the refrigerating chamber are communicated with an air inlet duct and an air returning duct so that a one-way circulating air path can be formed, a fan and a heat exchanger are arranged in the freezing chamber, a humidification branch is further communicated between the freezing chamber and the refrigerating chamber, the air returning duct is communicated an air inlet of the humidification branch in a forked mode, an air outlet of the humidification branch is communicated with the freezing chamber, an option switch is arranged on the forked portion of the air returning duct, a wet film humidifier is arranged in the humidification branch, a water receiving disc is arranged below the heat exchanger and connected with the wet film humidifier through a water delivery duct. The wet film humidifying system of the air-cooling refrigerator is low in manufacturing cost and environmentally friendly, has the function of automatic regulation and control and can achieve accurate humidity control.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and relates to the refrigeration and humidification application of a refrigerator, in particular to a wet film humidification system of an air-cooled refrigerator. Background technique [0002] The relative humidity in the refrigerating room of the existing single-system air-cooled refrigerator is generally much lower than the suitable humidity for keeping fruits and vegetables fresh. The reason is that the refrigeration of the refrigerator is achieved through the circulation of cold air, which needs to pass through the freezing evaporator in the freezer during the circulation process. low phenomenon. If the humidity in the refrigerator is too low, the moisture in vegetables and fruits will be lost rapidly, which is not conducive to freshness preservation. [0003] Aiming at the problem of low humidity in the refrigerator compartment of air-cooled refrigerators, there are curren...

AI Technical Summary

Problems solved by technology

Analyzing the existing solutions, it is more expensive to add an evaporator to the former dual-system solution, and it will occupy a certain space, reduce the storage volume, and cannot achieve humidity control

The second option uses an independent humidification system. If an ultrasonic nebulizer is used, energy consumption and noise will be generated. Moreover, the ultrasonic nebulizer has high requirements on water quality and requires an additional water source, which reduces the convenience of use.
