Description
Technical field
The present invention relates to temperature monitoring technique field more particularly to a kind of computer room hot and cold air leak judgment method and it is
System.
Background technique
With the continuous improvement of the level of IT application, as the data center of information system engineering construction " heart ", quantity
Constantly expand with scale, is just played an increasingly important role in national economy.In data center machine room, run big
The electronic equipments such as computer, the server of amount, these equipment heating amounts are big, while having strict requirements to environment temperature, are
The running environment of steady in a long-term, reasonable uniformity of temperature profile can be provided to these electronic equipments, data center machine room
Within the scope of reasonable, stable temperature that running environment also preferably must be held in.
The temperature of data center is mainly demonstrated by the equilibrium state of computer room internal calorific power and refrigerating capacity.When calorific value and
When refrigerating capacity is consistent, temperature is remained unchanged；When calorific value is higher than refrigerating capacity, temperature rises；When calorific value is lower than refrigerating capacity,
Temperature decline.In computer room, heat is mainly derived from the power consumption of information technoloy equipment, and the energy consumption of usual 97% or more information technoloy equipment is converted into
Heat；Refrigerating capacity then derives from the cooling capacity of refrigeration equipment generation, or the natural cold quantity obtained from the computer room external world.
The electronic equipment deployable state of each cabinet is different in computer room, causes the calorific value in each region of computer room uneven,
Refrigeration facility needs for suitable cold air to be sent into the equipment needed, so that every equipment has sufficient cold air to take away certainly
The heat that body generates.Only for the air-flow of computer room it is anticipated that distribution is flowed, the cold and hot balance of computer room is just in controllable state,
This will be managed the air flow condition of computer room, i.e. airflow management, and the premise for carrying out airflow management is to grasp the gas of computer room
Whether stream mode grasps hot and cold air and installs to be expected to distribute and flowed.
As illustrated in fig. 1 and 2, present computer room generally uses electronic equipment air inlet face to keep good air flow condition
Opposite, the aspectant mode of air outlet are disposed, and divide cold passage and the passage of heat, the two column machines that air outlet is arranged face-to-face in computer room
Cold passage is formed between cabinet, forms the passage of heat between the two column cabinets that air inlet is arranged face-to-face.Air-conditioning send out cold air from
Cold passage enters the air inlet of equipment, radiates；The hot-air of equipment blowout enters the passage of heat, by air-conditioning from return air inlet for air-conditioner
Sucking is freezed.In order to reach ideal air flow condition, data center machine room generally by the passage of heat, cold passage carry out every
From the air inlet and outlet of equipment is isolated, cold air, hot-air is not allowed to mix.Channel is shown in Fig. 1 and Fig. 2
Closed two kinds of principal modes.
The perfect condition of computer room air flow condition is that " cold air fully enters equipment air inlet, participates in heat dissipation；Hot-air is whole
Into refrigeration facility air inlet, freeze ", when air flow condition is abnormal, temperature shows following abnormal conditions:
1, cold air is escaped from cold passage, is not involved in heat dissipation, is entered the high-temperature area of computer room, cool island phenomenon occurs, heat
Path partially regional temperature reduces；
2, hot-air enters cold passage, sucks air inlet by equipment, heat island phenomenon occurs, and cold passage temperatures at localized regions mentions
It is high.
When cabinet closing is bad, it may occur that hot and cold air leakage not only causes energy waste, also equipment can be made in high temperature ring
It is run under border, influences the performance of equipment, reduce the service life of equipment.In addition, equipment replacement is frequent in data center, replacing
The sealing of cabinet is often destroyed when equipment, so that the cabinet closed leaks.
The method of existing monitoring hot and cold air leakage is to observe whether each cabinet leaks by manual inspection.Due to
Data center's cabinet is numerous, and manual inspection time interval is long, is easy to appear artificial careless omission, checks that efficiency and effect are relatively low,
So that mix phenomenon serious for computer room hot and cold air.
Summary of the invention
The technical problem to be solved by the present invention is to solve the above shortcomings of the prior art and to provide a kind of computer room hot and cold airs
Leak judgment method and system.
