Embodiment

[0045] In this embodiment, a large-scale computer room system adopts micro-space water-cooled heavy-duty cabinets, such as figure 1 As shown, it includes a computer room 1 and a cluster monitoring cloud 3, and several single core terminals 2 are set in the computer room.

[0046] Such as figure 2 As shown, a structure of a machine room is given. Air outlets 7 are arranged on both sides of the top of the machine room, and natural air inlets 8 are arranged at the lower part of the machine room. The air outlet is connected with a ventilation pipe 9, and the ventilation pipe extends to the upper part of the center of the monomer core end. The ventilation pipe is provided with two air ducts, one is a natural ventilation duct, and the other is a fan ventilation duct. A fan is installed at the air outlet.

[0047] Such as image 3 As shown, another machine room structure is given. The machine room is separated to form an upper ventilation chamber 10 on the upper part, a lower ven...

example 1

[0068] Example 1: Fault tolerance in refrigeration equipment, ie when one of the refrigeration compressors fails.

[0069] Check whether Y0 and Y1 are normal. If both compressors are normal, the Q value remains unchanged. If Q is 0, Y0 is the main compressor and Y1 is the backup compressor. If Y0 is normal and Y1 is abnormal, set Q to 0 and set Y0 is set as the main compressor, and an alarm signal Y1 is abnormal; if Y1 is normal and Y0 is abnormal, then Q is set to 1, Y1 is set as the main compressor, and an alarm signal Y0 is abnormal is sent to the cluster monitoring cloud. Whether the compressor is normal or not is provided by the pressure switch of the compressor. That is to say, the pressure of the compressor will deviate from the normal value regardless of power failure or leakage. The on-off signal is provided in time. The monitoring system cannot complete the switching action, and another The compressor remains in normal operation.

example 2

[0070] Example 2: When the ambient temperature is less than 35 degrees Celsius

[0071] The temperature control unit acquires an outside temperature of less than or equal to 35 degrees Celsius, and the processing unit analyzes and determines that the start-up temperature of the main compressor remains at a default value of 36 degrees Celsius. When the temperature in the cabinet exceeds 36 degrees Celsius, start the main compressor;

[0072] Before each cycle except the first cycle, the processing unit compares the last P td value, if the value is less than 30% then C td Add 1 to the value, according to the working time T of the main compressor m and standby compressor working time T s The ratio of P sm Displays the load condition of the compressor. When the number of cycles C is greater than 10 and P Ptd More than 30%, start the standby compressor, clear C and P Ptd , restart counting.

[0073] When the temperature control unit obtains that the temperature in the core ...

Abstract

The invention relates to a large-scale machine room system adopting a micro-space water-cooling large-load cabinet and a method. Problems that a current machine room is high in manufacture cost and large in energy consumption, and an individual load of a cabinet is limited by the refrigerating capacity of the machine room are solved. The system comprises a machine room and a cluster monitoring cloud terminal, wherein the machine room includes a plurality of individual core terminals; two sides of the top part of the machine room are provided with air outlets; and the lower part of the machine room is provided with natural air inlets. Each individual core terminal is internally provided with a water-cooling refrigerating unit, a temperature control unit, and a processing unit, wherein the temperature control unit and the processing unit are connected to the water-cooling refrigerating unit, respectively, and the processing unit is connected to the cluster monitoring cloud terminal. The system has the advantages that micro-space water-cooling technology replaces large-space refrigerating technology, so that loss of the refrigerating capacity is avoided; the cluster monitoring cloud terminal is provided, so that the worker number of the machine room is reduced, and labor cost is saved; and two compressors are switched, thereby avoiding operation of one compressor all the time and prolonging service lives of the two compressors.

Description

technical field [0001] The invention relates to a refrigeration constant temperature control technology for a computer room, in particular to a large computer room system and method using micro-space water-cooled and heavy-duty cabinets with double-compressor water cooling, movable, combined modular unit precise control, and simple structure. Background technique [0002] At present, the load of the cabinets used in the computer room of the large-scale computer data center is heavy, especially in the era of the cloud, the computing and storage of big data needs to be superimposed with more servers, in addition to fire prevention, shockproof, lightning protection, radiation protection and anti-static etc., higher requirements are put forward for the heat dissipation of the cabinet, and the cost of the equipment room is more expensive. [0003] Secondly, issues such as energy saving and consumption reduction have always been a huge problem. Medium and large computer rooms gene...
