Central refrigerator

Abstract

The invention discloses a central refrigerator and relates to the technical field of electric appliances. The central refrigerator comprises an outdoor main machine (A) and storage parts (B); the outdoor main machine (A) is connected with a plurality of storage parts (B); the outdoor main machine (A) comprises an electronic expansion valve (1), a condenser (2) and a compressor (3); the compressor (3) is connected with the condenser (2); the condenser (2) is connected with the electronic expansion valve (1); and the storage parts (B) comprise evaporators (3) and storage spaces. The central refrigerator only utilizes one main machine which is arranged outdoors, the noise is reduced obviously; the energy efficiency ratio can be improved greatly by adopting an air cooling or water cooling technology and other technologies; the power can be far less than the power sum of the original single refrigerator, the energy utilization maximization is achieved, energy is saved effectively, and low temperature preservation and high temperature preservation can be realized.

Description

Technical field: [0001] The invention relates to the technical field of electrical appliances, in particular to a novel refrigerator, in particular to a central refrigerator. Background technique: [0002] Refrigerator is one of the earliest domestically produced refrigeration appliances in China. It started in the early 1980s and has been developed for nearly 20 years. With the continuous development of the economy, the food culture has also developed. The demand is diversified, so the requirements for household refrigerators are getting higher and higher, that is, the more functions the refrigerator has, the better, and the larger the volume, the better. Traditional double-door refrigerators have long been unable to meet market demand, and have been replaced by multi-door, multi-temperature zone refrigerators. Such a refrigerator can independently set different temperatures for each storage space to meet the needs of different food preservation and storage, maximize the f...

AI Technical Summary

Problems solved by technology

[0004] Existing refrigerators have the following defects: 1. One refrigerator and one host; 2. After the refrigerator reaches the required temperature, it will no longer refrigerate, but the single refrigerator is still consuming energy; 3. Natural heat dissipation; 4. When placed indoors, the noise 5. The refrigerator includes the host part, which is large in size and takes up space, and the back of the refrigerator needs heat dissipation, so space must be reserved for heat dissipation; 6. The existing refrigerator is only used to maintain low temperature
