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.
