Detailed ways

In order to clearly illustrate the solution in the utility model, preferred embodiments are given in detail below. the

The temperature adjustment system in the embodiment of the utility model includes: a cold pool system, an air supply control system, and a central control system. the

Instructions are given below, see Figure 2. The cold pool technology is used to separate the hot and cold air in the computer room. The cold pool adopts double-layer glass, aluminum alloy frame, and sliding door design for heat preservation. The height and width are the same as the rack (including the base). The thickness is 30-80CM. the

For the upper air supply system, the cold air will be delivered to the air inlet above the cold pool through the air supply duct to supply air to the cabinet;

For the down-supply air system, air is supplied directly to the cabinet through the air intake duct (or static pressure box) under the floor opening under the cold pool;

The system is suitable for both updraft and downdraft rooms. the

In order not to occupy the maintenance space, the sliding door design is adopted. When the maintenance is required, the sliding door can be pushed to the two sides or the sliding door can be removed without affecting the operation next to it;

Due to the use of glass doors, maintenance personnel can clearly see the equipment running indicator light, which reduces the maintenance intensity of maintenance personnel. the

The cold air is sent to the cold pool according to the required air volume through the fan module placed at the air outlet. the

The fan module consists of a fan group and air guide louvers, as shown in Figure 3; the fan group consists of 1 to 8 fans, and the air volume is controlled by the air supply controller to control the fan speed or the number of fans to be turned on. the

In order to reduce the impact between the racks, a partition is installed between each rack, which can be disassembled for easy maintenance during maintenance. the

In order to reduce the loss of cold air, add blind plates to the gaps on the rack. the

The downflow fan room system uses the space under the floor as the main air duct, and sends the cold air directly to the air inlet below the cold pool; as shown in Figure 4. the

After cooling the equipment, the hot air is sent back to the return air outlet of the air conditioner in the computer room through the space of the computer room, and then cooled and then passed to the cold pool through the space under the floor. the

The upflow fan room system transmits the air outlet of the air conditioner in the sealed machine room to a branch air channel through the main air channel, and then sends the cold air to the air inlet above the cold pool through the induced air channel, and the hot air after passing through the cooling equipment is sent back to the machine room through the space of the machine room The return air outlet of the air conditioner is cooled and then passed to the cold pool through the air duct; as shown in Figure 5. the

For new computer rooms, intelligent air supply floors and intelligent air supply cabinets can also be used. the

See Figure 6. The intelligent air supply floor can directly replace the floor of the machine room and be placed at the air inlet of the cabinet. The floor is equipped with an air supply control system and a fan module system. The air volume is controlled by the air supply controller to control the fan speed and turn on the fan. quantity to complete. the

The intelligent air supply floor can directly replace the machine room floor and be placed at the air inlet of the cabinet. the

Refer to Figure 7 for the schematic diagram of the downflow intelligent air supply cabinet. The air supply module is installed under the air duct of the intelligent air supply cabinet. The floor opening is used as the air inlet, and the cooling air volume is adjusted through the fan module controlled by the air supply controller. To cool the equipment, in order to reduce the heat in the machine room, the hot air can be directly sent to the air-conditioning room through the optional return air duct; if there is no optional return air duct, the hot air will be transported to the air-conditioning return air outlet through the space of the machine room. the

Refer to Figure 8 for the schematic diagram of the up-flow intelligent air supply cabinet. The air supply module is installed above the forward air duct of the intelligent air supply cabinet. At the air supply outlet of the equipment, the fan module controlled by the air supply controller adjusts the amount of cold air to cool the equipment, and the hot air is delivered to the return air outlet of the air conditioner through the space of the equipment room. the

The cold pool system is described in detail above, and the air supply controller is described below. The air supply controller is designed according to the 2U chassis, and can be directly installed in the vacancy of the controlled cabinet (or the adjacent cabinet). The air supply controller can be set up and operated according to the logic block diagram shown in FIG. 9 . Install a temperature sensor at the air inlet of the server cabinet in the computer room, install multiple temperature sensors at the air outlet of the cabinet equipment, and install a current sensor in the cabinet where conditions permit, and the control chip in the air supply controller detects the cabinets in the computer room in real time The inlet and outlet air temperatures and the output power of the entire cabinet; calculate the required air volume according to the above detected data changes and adjust the air supply volume of each cabinet to meet the heat dissipation requirements of the server cabinet and avoid local overheating. to the central control system. the

The air supply control system transmits the data of the cabinet to the central control system. The working diagram of the central control system can be seen in Figure 10. The central control system will collect all the data and monitor the total power, temperature, humidity, and static pressure of the machine room. Calculate and compare the data, and finally determine the number of air conditioners in the computer room according to the needs to ensure the normal operation of the equipment in the computer room. the

Since the utility model only controls the opening state of the air conditioner and does not change the working condition of the air conditioner, the original design function of the air conditioner is not changed in any way, and the cooling capacity of the air conditioner is guaranteed. the

The utility model has the following technical effects:

1. Since the heating conditions of each cabinet are detected in real time and air is supplied to the cabinets according to actual requirements, the old computer room after the rectification of the computer room and the new computer room established using the technology of the utility model are firstly Thoroughly solve the problem of local overheating;

2. By using the utility model to solve the problem of local overheating, the cabinet can greatly increase the volume ratio of the equipment, and the equipment capacity of the cabinet can be increased from 2KW to more than 10KW, which is equivalent to increasing the utilization rate of the original computer room, thereby greatly reducing computer room construction costs;

3. The utility model can reduce the energy consumption of the air conditioner in the computer room by 30-60%, completely solving the problem of high energy consumption in the computer room. the

The environmental requirements for the equipment in the data center and communication center, that is, the design requirement for the air inlet of the equipment is 22°C ± 2°C. The cold air blown out by the air conditioner and the hot air in the machine room must meet this requirement when the machine room of the utility model is not used. The requirements can only be met after mixing, but at this time we set the return air temperature of the air conditioner to be 22°C±2°C, so that the air conditioner will turn on the refrigeration compressor when the measured return air temperature is greater than 24°C, and turn off the compressor when the temperature is less than 20°C Since the evaporation temperature of the air conditioner in the computer room is generally 8-10°C (calculated as 8°C below), the air temperature of the air conditioner after the compressor is turned on for cooling is 12-16°C. This may cause some places to be too cold and some places to be overheated, so that some places may be cooled by the air conditioner while others may be heated, resulting in a lot of waste and excessive energy consumption of the air conditioner in the computer room. the

The utility model can separate the hot and cold air, and the cold air refrigerated by the air conditioner can be directly sent to the air inlet of the cabinet equipment. We only need to make the microenvironment of the cabinet reach the design temperature required by the equipment to meet the equipment needs, so that there is no need to The entire environment must be 22°C±2°C. Since the evaporation temperature of the air conditioner in the computer room is 8°C, we can increase the return air temperature of the air conditioner by 8°C in an ideal state, thereby achieving the goal of energy saving. the

4. First of all, the scope of the air conditioner is changed from the large environment to the micro environment, which reduces the burden of the air conditioner. the

5. Due to the increase of the ambient temperature of the computer room, the heat radiation outside the computer room is reduced, and the cold radiation outside the computer room is increased. the

6. As the return air temperature of the air conditioner in the computer room is increased, the cooling efficiency of the air conditioner in the computer room is increased. According to expert calculations: for every 1°C increase in the return air temperature of the air conditioner, the cooling efficiency of the air conditioner increases by 3%. the

7. Due to the central centralized control and fixed-point control system, the temperature of each point in the computer room is basically balanced, and local overheating and local overcooling will not occur. The opening of the air conditioner in the computer room can be precisely adjusted as required to avoid excessive opening The phenomenon of computer room air conditioning reduces unnecessary waste. the

For the system described in each embodiment of the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. the
