Data center energy-saving device with ground source as cold source and running mode of data center energy-saving device

Abstract

The invention relates to the technical field of air conditioning systems or equipment, and in particular to a data center energy-saving device with a ground source as a cold source and a running mode of the data center energy-saving device. The device is composed of two circulating systems, and the first circulating system is a ground source circulating system composed of a ground source extracting system (1), a circulating pump (6) and a heat exchanger (2); and the second circulating system is a chilled water circulating system composed of a dry cooler (3), a standby application cold machine (4), a machine room precise air conditioning heat dissipating end (5), the circulating pump (6) and a cold storage unit (7). According to the device, the characteristics of cold storage by the ground source, direct utilization of environment temperature, circulating utilization and the like of the environment of the winter in the northern part are fully utilized, and the ground source and natural resources of low-temperature outdoor environment and the like in winter are utilized as cold sources, so that the cold source need of refrigeration of a data center air conditioner is met. The data center energy-saving device with the ground source as the cold source is provided for people, data center energy consumption is greatly reduced, and the aims of setting up a green data center, saving energy and reducing emission are achieved.

Description

[0001] technical field [0002] The patent of the present invention relates to the technical field of air-conditioning systems or equipment, in particular to an energy-saving device for data centers using ground sources as cold sources and its operating mode. Background technique [0003] According to data, in the electricity consumed by each data center, the energy consumption of air conditioning and refrigeration accounts for 40% to 50% of the total energy consumption, which has a considerable proportion. The cold source energy saving scheme in the data center project has become a data center An important part of the overall energy saving, the data center has high requirements for the stability of the air conditioner, which runs stably for a long time and is in the cooling working state all year round. Ordinary compressor refrigeration consumes a lot of power and is not energy-saving; some energy backup methods for emergency situations are insufficient, resulting in low ...

AI Technical Summary

Problems solved by technology

Ordinary compressor refrigeration consumes a lot of power and is not energy-saving; some energy backup methods for emergency situations are insufficient, resulting in low reliability of data center system operation; The outdoor temperature is low, or the temperature difference between morning and evening is large in summer or other seasons. Make full use of the natural cooling source to replace the compressor operation to achieve the purpose of reducing the cooling energy consumption of the air conditioner in the data center. However, due to the limitation of the environment and temperature difference, the energy saving effect is limited. Especially in summer, it still needs to consume a lot of electricity to meet its cooling needs
