Cool storage and cool supply system for data equipment

Abstract

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.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a cold storage and cooling system for data equipment. Background technique [0002] At present, the method of mobile communication for emergency cooling in data centers mainly adopts the method of series serpentine tubes. That is, a serpentine pipe with a large diameter is connected in series with the original central air-conditioning system. When the original central air-conditioning refrigeration unit fails to operate normally, the UPS power supply is used to start the chilled water pump to pump out the chilled water stored in the serpentine pipe for emergency use. For cooling. This method mainly has the following advantages: (1) The response time is relatively fast; (2) The construction is simple and no water distribution device is required. However, there are also the following disadvantages: (1) When the refrigeration host is normally used for cooling, each cycle of chilled...

Problems solved by technology

But there are also the following disadvantages: (1) When the refrigeration host is normally used for cooling, each cycle of chilled water must pass through the serpentine tube, which greatly increases the power consumption of the water pump. Increased operating electricity costs by hundreds of thousands of yuan

(2) The serpentine tube occupies a relatively large area and has a relatively large heat dissipation area, which not only increases the cost of heat preservation but also increases the loss of cooling capacity, resulting in a waste of energy

(3) There is a series mode between the serpentine tube and other equipment of the air conditioning system. In this mode, if any link fails, it will bring huge losses

Therefore, its repair risk and maintenance cost are high
