The invention provides cold-storage and refrigeration equipment. A first sealing space and a second sealing space are formed in an internal storage space of the cold-storage and refrigeration equipment; the cold-storage and refrigeration equipment is further provided with a nitrogen making device; the nitrogen making device comprises an adsorption device and is configured to supply compressed air to the adsorption device, and the adsorption device is enabled to be communicated to the first sealing space, so that the adsorption device is enabled to make nitrogen and supply the nitrogen to the first sealing space; after the compressed air supply to the adsorption device is stopped, the adsorption device is enabled to be communicated to the second sealing space and is enabled to desorb oxygen-rich gas and supply the oxygen-rich gas to the second sealing space. According to the cold-storage and refrigeration equipment, the oxygen-rich gas is supplied to the second sealing space, the content of oxygen in the second sealing space is increased, and accordingly, biological activity of food in the second sealing space can be guaranteed by the aid of the cold-storage and refrigeration equipment.
