The power supply, the uninterruptible power supply and other features can be included. In order to keep the room at a constant temperature, the heat generated by the instrument in the room must be excluded. As advances in technology have led to an increase in the density of electronic devices that can be provided in a given amount of space, it has become more difficult to remove the heat generated by electronic devices using conventional indoor air conditioners. Cooling systems typically used in indoor and open spaces are not too bulky today, and the efficiency of handling additional cooling requirements is too low to be applied to single-frame critical electronics that can carry very large loads. Therefore, it is often necessary to install local cooling for cabinets of electrical equipment. Some existing suppliers have provided closed loop cooling to the cabinet; the east cooling line. The refrigeration system generally comprises a S-shrinking machine, wherein the refrigerant is compressed to a rising pressure in the system; the cooling agent is cooled by heating while being compressed; the expansion device is 125914.doc 200838412, It cools the cold by thermodynamic action; the east agent; the flow of the evaporator 得到 is cooled; the fan, which causes the air to flow and passes through two: = cooling air, whereby the cold agent transfers to absorb warmer air.

These systems are usually placed at the bottom or top of the cabinet. Standard cabinets are approximately 24 inches wide and 78 inches to 84: high. The cooling mold is assembled at the bottom of the cabinet to occupy approximately 空 inches to 15 inches from the bottom, but if installed at the top, the height of the cabinet must be increased. Although individual cooling systems per cabinet have been accepted, they add cost per cabinet and system complexity. Another problem with existing electronic equipment cabinets with built-in cooling coils and fans is that the thermal reaction is often too fast to react quickly. The cooling system senses the heat before the heat has been generated, and then attempts to compensate with additional cooling to lower it to a predetermined set point with IV low temperature. Therefore, the cooling system reacts to heat after heat has been generated. Due to the reflection of the load system's control system, the temperature inside the cabinet caused a large fluctuation. Therefore, there is a need to improve the cooling system in the cabinet of an electronic device. SUMMARY OF THE INVENTION The present invention provides a central cooling system that selectively transmits different power to individual power load units, such as individual cabinets, shelves of such cabinets, or other cooled units. The system can be sensed to provide direct cooling from a manifold with multiple cooling ports based on sensing a specific cabinet, rack or other single 7L electrical load. The system typically includes a branch monitoring system coupled to each of the branch circuits being monitored, the branch circuits being electrically routed 125914.doc 200838412: 5 to more electrical load cells; and controllers consuming the branch monitoring system.

Data can be transferred between branch monitoring systems, controllers, cooling units or combinations thereof. If a load change and/or load change is sensed for a certain (or evening) power load unit, the controller can drive a cooling valve that engages the corresponding cooling port and change the flow of the cooling fluid into the power load or to the power load unit. The amount around. In addition, a single or multiple thermal sensors can be mounted on the load unit to provide feedback from the unit regarding cooling conditions so that the controller can make adjustments as needed.

BCMS is available from Libert, Inc., Columbus, Ohio, USA. Each electrical load cell typically needs to be cooled to avoid overheating and premature failure that may be caused by electrical loads. The central cooling unit 28 can be used to provide cooling: an electrical load unit. The central cooling unit flows cooling fluid through the central gripping channel 30, and the central central flow conduit is typically branched to a plurality of cooling ports 32 which are coupled to the electrical load carrying unit to be cooled. The cooling medium can be a gas such as air, or a liquid such as cold water, and can include an air conditioning or water cooling system. Depending on the cooling needs of the electrical load cell, a single cooling port or multiple cooling ports can cool individual electrical loads by varying the amount of cooling between the electrical load cells based on individual power loads of the distributed electrical load cells, for example A unit or a group of electrical load cells. Typically, a control valve, such as a throttle or liquid flow valve, is coupled to each of the cooling ports, which can control the flow of cooling fluid from the jaws to the power load unit to flow through the central flow conduit 3 at a particular time. The part of the total cooling fluid flow. If a specific electrical load cell senses an increase in electrical load 125914.doc -11- 200838412 plus, the controller can indicate that a larger portion or cooling flow flows from the central flow conduit through the associated cooling port to the particular electrical load cell. Changes are possible. For example, some of the electrical load cells may have significant variations in electrical load and one or more other electrical power • The load cells may have a relatively constant electrical load. The controllable chiller can be adapted to provide variable cooling to the variable power load unit while a relatively constant cold fluid supply can be supplied to one or more constant electrical load units. In such an embodiment, the control valve can optionally be omitted from a constant power load unit. Thus, control valve 34 provides for the deuteration of cooling fluid from central flow conduit 3 through cold port 32. System 2G further includes data and output/input control for control valve 34. More specifically, system 2A includes data communication lines 44 from power distribution center 22. Controller 38 can be coupled to the power distribution center, particularly bcms, via electronic communication via data communication line 44. The data communication line can be wired or wireless. For example, microwave, infrared •, line, radio wave' or other communication modes. Controller 38 typically includes input and output 'acceptance data and output processing data through data communication line-like cooling unit 28 for controlling the cooling unit. In some embodiments, the controller 38 can be substantially integrated with the cooling unit 28 so that the data at the BCMS and the controller can be represented by the data communication line 5G. Control (4) is also face-to-face, directly or indirectly, to control the busbar 4〇. The control bus 4 can provide control communication between control 1 § 38 and control valve 34. The "Control Bus" link can be used in a wide range and can include wired or wireless communication. When the load is increased or decreased, the controller 38 can instruct the control valve 24 to increase or decrease the flow using the control unit. 125914.doc -12- 200838412 The amount of cooling fluid for a particular cooling port 32. The controller 38 can also control the cycle time and average temperature in the cooling unit 28, such as central flow piping and other system-wide parameters, for more conventional operation. In some embodiments, the electrical load unit It can be more sensed by one or more portions of the temperature sensor or power load unit. The sensor 42 can be coupled to the control bus 40 and provide additional input to the controller 38.
