Refrigeration container and control method thereof

Abstract

The invention provides a refrigeration container and a control method thereof. The refrigeration container comprises a refrigeration system. The refrigeration system comprises a refrigeration branch and a cold storage branch which are connected with the two outlet ends of a bi-stable electromagnetic valve. The refrigeration branch and the cold storage branch are connected in parallel. Cold can be stored for a cold storage device through the cold storage branch by means of a gap, where refrigeration is not needed, of a refrigeration chamber, and a compressor halts on the premise that the temperature TR of the refrigeration chamber is lower than the set lower limit temperature TRD of the refrigeration chamber and the temperature TX of the cold storage device is also lower than the set lower limit temperature TXD of the cold storage device; then, the refrigerating capacity stored by the cold storage device supplies cold to the refrigeration chamber. The starting and stopping frequency of the compressor is decreased, and the service life of the compressor is prolonged; when people have a rest, the refrigeration chamber is refrigerated by means of the refrigerating capacity stored by the cold storage device, noise generated when a refrigeration system of a refrigerator works is eliminated, and the living quality of a user is improved.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator capable of delaying the natural temperature rise of a refrigeration compartment after a compressor is shut down and a control method thereof. Background technique [0002] When the existing refrigerator is in normal operation, when the temperature in the refrigerating compartment is higher than the set temperature, the compressor will start to cool the refrigerating compartment. Causes the compressor to start and stop frequently, shortening the service life of the compressor. At the same time, when the compressor is turned on at night when the user is resting, it will generate a certain amount of noise, which will reduce the quality of the user's rest. [0003] Chinese patent No. CN2497254Y discloses a time-sharing operation refrigerator, which adds a cold storage branch connected in parallel with the refrigeration branch on the refrigeration system of the refrigerator; a cold st...

Problems solved by technology

In this way, since the start-up of the compressor is controlled by time, the compressor is still in the power-on state after the storage of cold energy in the cold accumulator is completed, which causes a waste of cold energy; Resulting in a weak cooling effect on the cold storage room and cold storage, while increasing the burden on the compressor
