Description
Technical field
The present invention relates to a kind of cloud case safety temperature control technical field, particularly relate to a kind of phase-changing energy-storing safety temperature control system and method for cloud case.
Background technology
Cloud case, claim again cloud container, a kind of general designation of container type machine room series of products, it utilizes container for carrier, in container, place the required various device of machine room running environment, such as power-equipment, refrigeration plant, server apparatus, fire-fighting equipment, watch-dog etc.Cloud case can form miniature data center, middle-size and small-size data center, large-scale data center, can meet the demand of the many scenes of client, many application.Qi He conventional internet data center (Internet Data Center, be called for short " IDC ") compares, and has lot of advantages, and main manifestations is: adopt high density designs, 5 times of calculated capacities are to same area tradition machine room; Can be as required, step by step, rapid deployment, tackle in time dynamic service demand; The power supply service efficiency of container (Power Usage Effectiveness is called for short " PUE ") value can be down to 1.5, and energy consumption saving can reach 30%; Save 75% space, the functional module of container plug and play forms, and allows IDC become off-the-shelf from engineering.
Cloud case adopts the state-of-the-art water-cooled of industry, the technology such as natural air cooled, and its PUE can reach 1.2-1.4.And the PUE of conventional internet data center is greater than 2, during better situation, PUE is between 1.5-2, as the Tianjin data center of Tengxun just will be controlled at 1.5 left and right PUE.
As special data center, conventionally by a class mains-supplied, it is generally from two reliable and stable independent current sources and introduces separately a road supply lines.This two-way should not occur that maintenance has a power failure simultaneously, and on average monthly frequency of power cut should not be greater than 1 time, and should not be greater than 0.5 hour average each fault time.
But the data center of a lot of basic units, does not have the treatment of a class mains-supplied, can only enjoy two class commercial power supplies, its supply line allows planned maintenance to have a power failure, and on average monthly frequency of power cut should not be greater than 3.5 times, and should not be greater than 6 hours average each fault time.
Once after power-off, need storage battery power supply, be its corresponding setup time: the signal centre of a class mains-supplied, middle-size and small-size integrated communication office will reach electric discharge in 1 hour.The signal centre of two class mains-supplied, middle-size and small-size integrated communication office will reach electric discharge in 2 hours.
After the power-off of cloud case, generally there are two kinds of operational modes: one is pure communication device works; It two is that communication equipment and uninterrupted power supply (Uninterruptible Power System is called for short " UPS ") are worked simultaneously, and now refrigerating system is driven by UPS, can continue to move 10 minutes.Conventionally lose after refrigeration, after short a few minutes, device temperature just can, up to 55 degrees Celsius, cause shutting down or burning the fault of machine.At present, the storage battery that cloud case configures can reach electric discharge in 0.5 hour (during pure support communication equipment); Or electric discharge (while simultaneously supporting communication equipment and UPS) in 0.25 hour.Obviously, current cloud case not yet reaches after power-off can effectively provide to internal unit the requirement of safety temperature control.
