Double-cold-source and multi-working-condition water cold storage system

Abstract

The invention discloses a double-cold-source and multi-working-condition water cold storage system. According to the double-cold-source and multi-working-condition water cold storage system, a cooling tower, a refrigeration host and a cold storage tank arranged are arranged with an end load to form a circulation loop for supplying cold to the end load; the cooling tower and the refrigeration host are arranged with the cold storage tank to form a circulation loop; a cold source is stored in the cold storage tank, cold is supplied to the end load through the cold storage tank; the refrigeration host, the end load and the cold storage tank are arranged in a parallel manner, thus multi-mode cold supply and cold storage are realized as a whole; the cold storage can be carried out through the refrigeration host or natural cooling, thus the problem of a single cold source of cold storage of a traditional water cold storage system is overcome; and moreover, the cold storage is carried out through the natural cold source, thus the cold storage cost is low. The double-cold-source and multi-working-condition water cold storage system disclosed by the invention is suitable for the field of cold supply and cold storage air-conditioning systems.

Description

technical field [0001] The invention relates to the field of cold supply and cold storage air conditioning systems, in particular to a water cold storage system with dual cold sources and multiple working conditions. Background technique [0002] With the development of electronic information technology, especially the continuous evolution of diversified Internet applications and the transformation of traditional telecom operators to ICT, the scale of IDC (data center) is increasing, the heat generated by IT equipment is increasing, and the power of a single rack is increasing. For the normal operation of the servers in the data center, the cooling capacity that needs to be provided for the data center is also increasing, and the operating cost of the entire air conditioning system is also increasing rapidly. [0003] At present, my country is divided into severe cold regions, cold regions, mild regions, hot summer and cold winter regions, and hot summer and warm winter regi...

AI Technical Summary

Problems solved by technology

[0004] However, in the air-conditioning system of the data center, the use of natural cooling sources to cool the equipment in the data room is rarely involved. This is especially important for some areas of my country where the data room is built in the transitional period of autumn and winter and the ambient temperature is lower than 10°C in early spring. The natural cold source is not fully utilized, and the waste of cold source is huge

In some existing designs, some also take into account the use of natural cooling sources, but there are also certain defects

That is to say, when the natural cooling source is lacking and cannot meet the load demand, it will be supplemented by refrigeration through the main unit. At this time, due to the small supplementary cooling capacity, the cooling efficiency of the main unit is very low.

The cold storage capacity of the commonly used water storage system basically comes from the refrigeration main unit, which consumes a lot of power. Although the low-valley electricity price is used for cooling to save the cost of the cold source, in areas where natural cold sources are available, the main unit does not store cold for the cold storage tank. The most economical way to store cold
