The invention discloses a
cool storage and cool supply
system for data equipment. The
cool storage and cool supply
system comprises an air conditioner terminal, a
refrigeration host machine, a control device, and a monitoring device for measuring the
cool storage capacity of a cool storage water tank; the air conditioner terminal is connected with the
refrigeration host machine for forming a primary circuit; the
refrigeration host machine is connected with the cool storage water tank for forming a
secondary circuit; the air conditioner terminal is connected with the cool storage water tank for forming a
tertiary circuit; the monitoring device is connected with the control device; and the primary circuit, the
secondary circuit and the
tertiary circuit are each provided with a flow control device for controlling the on-off of the corresponding circuit. On a normal cool supply condition, the refrigeration host
machine directly supplies cool to the air conditioner terminal, and the
secondary circuit and the
tertiary circuit are disconnected; when the monitoring device monitors that the cool supply capacity for redundancy
backup in the cool storage water tank is not sufficient, the secondary circuit works, a cool storage program is started, and the primary circuit and the tertiary circuit are disconnected; and when an electric
system is powered off, or on other emergency occasions, the tertiary circuit works, a cool
discharge program is started, the primary circuit and the secondary circuit are disconnected, and the cool storage water tank is directly adopted for emergency cool supply.
