Abstract

The invention discloses a double-circuit natural cooling type air conditioning system and a control method of the double-circuit natural cooling type air conditioning system. The air conditioning system comprises a refrigeration / natural cooling circuit and a natural cooling circuit. The refrigeration / natural cooling circuit comprises a compressor, a first evaporative condenser, a first refrigerant pump, and a first evaporator. An inlet of the first evaporative condenser communicates with an outlet of a compressor. An inlet of the compressor communicates with an outlet of the first evaporator. An outlet of the first evaporative condenser communicates with an inlet of the first evaporator through a first refrigerant pump. The natural cooling circuit comprises a second evaporative condenser, a second refrigerant pump and a second evaporator. An inlet of the second evaporative condenser communicates with an outlet of the second evaporator. Evaporator proportions and the size of the compressor can be configured according to specific application environment, so that the system cost is reduced, and meanwhile, natural cold sources are fully utilized to improve energy efficiency.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to a dual-circuit natural cooling air-conditioning system. Background technique [0002] Human beings have entered the era of big data, and the scale and quantity of data centers have developed rapidly, and they have become major electricity consumers in the information society. In order to ensure the efficient and reliable operation of the data center, it is necessary to quickly discharge the heat generated by the servers in the data center during operation. According to statistics, the power consumption of data centers in modern society accounts for 5% of the total electricity in the whole society. The IDC industry research report shows that as of 2016, the scale of data centers reached 71.45 billion yuan. In 2017, China's data centers consumed more than 125 billion kWh of electricity, exceeding the annual power generation of the Three Gorges Hydropower Station and the Gezhouba Hydr...
