Double-cold-source data centre and temperature control method

Abstract

The embodiment of the invention provides a double-cold-source data centre and a temperature control method. The double-cold-source data centre comprises a shell body, at least one server cabinet, a heat exchanger, a first refrigeration unit, a second refrigeration unit and a third refrigeration unit, wherein the first refrigeration unit is a cooling water unit; the second refrigeration unit is a closed cooling tower; and the at least one server cabinet is arranged in the shell body. According to the scheme, a double-cold-source liquid cooling manner is adopted, the running mode of a double-cold-source liquid cooling system is selected according to the dry-bulb temperature and the wet-bulb temperature of outdoor air, whole-year startup of a compressor is avoided, and the problem that the extreme weather condition is difficultly coped by a single cooling tower system is avoided; energy-saving cooling, accurate control, and safe and reliable running for the data centre of a container arerealized; and the problems that an air cooling end is low in heat dissipation capacity, an indoor unit and an outdoor unit occupy much space, the number of the placed cabinets is low, and the like, ofthe existing data centre, can be solved.

Description

technical field [0001] The invention relates to the technical field of data centers, in particular to a data center with dual cooling sources and a temperature control method. Background technique [0002] The traditional cooling method of the data center usually adopts the cooling method of cooling the air with a refrigerant and using the cold air to take away the heat of the server. This end-air cooling method has the advantages of mature technology, simple and safe system. With the development of the scale of the data center, the power density of the data center is getting higher and higher. If the traditional air-cooled cooling method is adopted, the power density of the data center using the floor air supply can only support a single cabinet of 3-5kW. The data center can increase the power density to 8~15kW for a single cabinet. When the power density increases, measures such as increasing the air supply volume and reducing the supply air temperature must be taken. The ...
