Abstract

The invention discloses an air conditioning control method of a refrigerator, an air conditioning drawer and a fresh-keeping refrigerator. Wherein, the method includes: monitoring the oxygen concentration of the drawer and the pressure difference inside and outside the drawer when the drawer is closed; controlling the opening and closing of the vacuum pump in the nitrogen-oxygen separation membrane module and the air pipe The opening and closing of the air intake hole of the road channel. The invention realizes the linkage control of the nitrogen-oxygen separation membrane module and the air inlet switch of the air pipeline channel, which can not only adjust the gas concentration of the drawer to effectively keep the refrigerated food fresh, but also solve the problems of drawer deformation and negative pressure, so that The drawers are easy to move and secure.

Description

technical field

[0001] The invention relates to the technical field of fresh-keeping refrigerators, in particular to a controlled atmosphere control method of a refrigerator, a controlled-atmosphere drawer and a fresh-keeping refrigerator. Background technique

[0002] Controlled atmosphere fresh-keeping storage refers to the refrigeration method in a specific gas environment. The oxygen content in the normal atmosphere is 20.9%, the carbon dioxide content is 0.03%, and the nitrogen content is 78%, while controlled atmosphere storage is based on low temperature storage, adjusting the content of oxygen, carbon dioxide, and nitrogen in the air, that is, changing the storage environment. Composition, by reducing the content of oxygen, increasing the concentration of carbon dioxide or nitrogen, and according to the different requirements of the storage, the gas composition is kept in the desired state. The principle is: fresh fruits and vegetables are still undergoing vigorous ...
