Energy-saving machine room air conditioning system

Abstract

The invention relates to an energy-saving machine room air conditioning system. The energy-saving machine room air conditioning system comprises an indoor unit, an outdoor unit and a control unit, theindoor unit comprises a heat pipe evaporator, an indoor fan and a mechanical refrigerating device, and the heat pipe evaporator is provided with a gaseous refrigerant outlet and a liquid refrigerantinlet; the mechanical refrigerating device comprises an evaporator, a condenser, a compressor and a throttling device; and the outdoor unit comprises a heat pipe condenser and an outdoor fan, the indoor unit is in fluid communication with the outdoor unit through a refrigerant pipeline, the position of the outdoor unit is higher than that of the indoor unit, the heat pipe condenser is arranged onthe outer side of the condenser of the mechanical refrigerating device, the evaporator of the heat pipe heat exchange system is arranged on the left side of the condenser of the mechanical refrigerating device, and the control unit automatically controls the natural cold source and the mechanical cold source to be in an independent operation mode and a combined operation mode. The heat pipe technology and the compressor refrigeration technology are perfectly combined, a natural cold source is effectively utilized to achieve the energy-saving purpose, and the PUE value of a data machine room isreduced.

Description

technical field [0001] The present invention relates to a computer room air-conditioning system, more specifically, the present invention relates to an energy-saving computer room air-conditioning system. Background technique [0002] With the continuous expansion of data centers, green and energy-saving data centers have moved from concept to reality. More and more data centers use the PUE value as a key indicator during construction, and pursue a lower PUE value. Building a green data center should become the consensus of the industry. For example, the PUE value of Microsoft's data center in Dublin is 1.25. According to the latest report, the PUE value of Google's existing data center has been reduced to 1.11. The average PUE of my country's data centers is 1.8 to 2.0. According to the survey and statistics of domestic data centers, for data centers that have not adopted significant energy-saving measures, the annual power consumption of a computer room with an area of ​...

AI Technical Summary

Problems solved by technology

The energy consumption of air-conditioning and cooling in each data center is very different. A good air-conditioning and cooling solution can greatly reduce energy consumption. To achieve partial energy saving, the natural cold source cannot be utilized to the maximum extent, and the system has complex pipelines, large one-time investment and long construction period
