specific Embodiment

[0027] When the outdoor temperature Ta≥30°C, the compressor is turned on, the outdoor fresh air passes through the nozzle to reduce the temperature, evaporates and exchanges heat with the atomized water sprayed by the atomizing spray device for the second time, and then passes through the heat exchanger with the return air in the machine room Indirect heat exchange, and then discharged through the exhaust outlet 11 after heat exchange with the condenser; the return air is exchanged with the fresh air in the heat exchanger for a second time to cool down through the heat exchange of the heat pipe internal unit, and then exchanged with the evaporator After cooling down for three times, it is sent out through the air supply port, and the processed cold air enters the data center through the air supply port to cool down the IT equipment and power distribution equipment;

[0028] When the outdoor temperature is 15°C<Ta<30°C, the compressor is turned off for cooling, and the evaporato...

Abstract

The invention relates to a multi-system refrigeration air conditioning unit. The multi-system refrigeration air conditioning unit comprises four parts of heat pipe refrigeration, nozzle refrigeration,evaporation heat exchange refrigeration and mechanical refrigeration, wherein different parts and different parts of the four parts are selected and combined for refrigeration at different outdoor temperatures. According to the scheme, heat pipe refrigeration, nozzle refrigeration, evaporation heat exchange and mechanical refrigeration technologies are combined, and different refrigeration modesare enabled according to different outdoor temperature conditions, so that energy conservation and consumption reduction can be achieved in a data center, PUE can be reduced, and product competitiveness of the data center can be improved.

Description

technical field [0001] The invention relates to the technical field of data center refrigeration equipment, in particular to a multi-system refrigeration and air-conditioning unit. Background technique [0002] With the rapid development of the electronic information industry, the development of data centers has also entered a new stage. According to statistics, data center air-conditioning accounts for about 40% of the entire data center's energy consumption. The more air conditioners are used, the more power they consume, which directly leads to the crisis of power cuts in summer and the problem of a large amount of energy consumption. In this case, free cooling technology refers to the use of natural free cold sources for cooling in whole or in part to reduce the energy consumed by compressors or freezers. The free cold source commonly used at present is mainly the outdoor air in winter or spring and autumn. In China, the northern regions are very suitable for adopting...
