Problems solved by technology
[0003] In recent years, in order to save the energy consumption of the air conditioner in the computer room, the natural cooling source is used for cooling in winter when the temperature is low, and the air conditioner compressor is still used for cooling in other seasons. Since a large part of the year is used for compressor cooling, the cooling The energy consumption of the system is relatively high. Therefore, in the prior art, a refrigeration control system with a closed loop of compressors, condensers, circulation pumps, throttling elements and evaporators connected in sequence has been gradually developed. However, in this system, due to Controlling only the compressor and circulation pump still has the problem of high energy consumption in the overall refrigeration process

Embodiment Construction
[0073] In order to reduce the cooling energy consumption of the machine room and improve the energy utilization rate, the present invention provides a cooling control system, method and device for the machine room. In this technical scheme, the condenser using the outdoor cold source is rationally designed. The condenser includes an air-cooling device and a water-cooling device, and the compressor, the circulation pump, and the water pump and fan of the condenser are adjusted according to the outdoor temperature. The technical solution of the present invention uses different operating modes according to the difference of outdoor temperature, and in each operating mode, the cooling capacity required by the machine room is guaranteed with the minimum power consumption, so it is beneficial to reduce the cooling energy consumption of the machine room and improve energy utilization Rate. In order to make the purpose, technical solution and advantages of the present invention cleare...

The refrigeration control system includes: a compressor, a condenser, a circulation pump, a throttling element and an evaporator which are connected in sequence through pipelines to form a closed circuit, and the pipeline has refrigerant; Coil, an air-cooling device for air-cooling the heat exchange coil, and a water-cooling device for water-cooling the heat exchange coil; a first temperature sensor, used to detect the outdoor temperature; a control device, used to adjust the compression machine, circulating pump, and condenser fan and water pump. The cooling control system of the present invention can reduce the cooling energy consumption of the machine room and improve the energy utilization rate.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration control system, method and device for a machine room. Background technique [0002] A data center, commonly known as a computer room, is a complete set of complex facilities. It not only includes computer systems and other supporting equipment (such as communication and storage systems), but also includes redundant data communication connections, environmental control equipment, monitoring equipment, and various safety devices. In existing data centers, energy costs account for a relatively high proportion of computer room operating costs, and less than half of the electricity is used for IT loads, while the rest is used for infrastructure such as power supply and cooling systems. According to the survey, in the computer room, only the power consumption of the precision air conditioner accounts for more than 50% of the total power consumption of t...
