Natural cooling system adopting reverse-flow air heat exchange for data computer room, and control method thereof

Abstract

The invention relates to the technical field of air-conditioning systems for data computer rooms, and discloses a natural cooling system adopting reverse-flow air heat exchange for a data computer room. The natural cooling system is applied to the data computer room, and comprises a heat exchanger and a server cabinet, wherein the server cabinet is arranged in the data computer room; the heat exchanger is a reverse-flow air heat exchanger, and comprises an inner circulating air duct, an outer circulating air duct, and a heat exchange core used for carrying out heat exchange on air in the inner circulating air duct and the outer circulating air duct; and flow guide fans are arranged at an air outlet port of the inner circulating air duct and an air outlet port of the outer circulating air duct respectively. The natural cooling system further comprises a compressor refrigeration system, wherein the compressor refrigeration system comprises an indoor unit and an outdoor unit; the indoor unit is connected with the outdoor unit through a refrigeration pipeline; and an air outlet port of the indoor unit communicates with a space below a raised floor. The natural cooling system disclosed by the invention carries out refrigeration by virtue of the reverse-flow air heat exchanger in low-temperature seasons and carries out refrigeration by virtue of a compressor system in high-temperature seasons. The whole system adequately utilizes a natural cold source of outdoor fresh air for indirect heat exchange, thus saving energy and increasing efficiency.

Description

technical field [0001] The invention relates to the technical field of an air-conditioning system for a data computer room, in particular to a natural cooling system for a data computer room using counterflow air heat exchange and a control method thereof. Background technique [0002] The equipment in the data center generates a huge amount of heat during operation. For the normal operation of the equipment, it is necessary to cool down the equipment in the equipment room to keep it at a stable temperature and humidity. The traditional cooling method mainly adopts the vapor compression refrigeration air-conditioning system. Because the compressor needs to be used all year round, the air-conditioning system consumes a lot of energy, and its air-conditioning energy consumption can account for 40% to 50% of the overall energy consumption of the data center. [0003] From the perspective of energy saving, there are currently plans to directly use outdoor cold sources including ...

Problems solved by technology

However, the limitations of this method are: the time period for direct use of outdoor natural cooling sources is short (the temperature of the treated water is higher than 5°C in most of the year), the energy saving is not large, and the amount of on-site installation is large. The maintenance workload is also large
