Description

Technical Field

[0001] This invention relates to the field of computer room control equipment technology, specifically to an overall intelligent temperature control and energy-saving system for the main control room computer room. Background Technology

[0002] Because the main control room contains servers, control hosts, electrical cabinets and other equipment, these devices generate a lot of heat when they are running. If the heat is not dissipated in time, the temperature in the room will continue to rise, which will affect the normal operation of the equipment, and may even cause equipment damage and safety accidents.

[0003] To address the issue of rising temperatures, temperature control systems are installed in the main control room and computer room. Existing temperature control systems consist of multiple air conditioning units installed in different locations. However, these air conditioners lack coordination during operation and work independently. When the temperature is uneven throughout the computer room, some air conditioners operate at high loads while others remain idle. This causes severe performance degradation and reduced lifespan for some air conditioning units, and prevents them from achieving rapid localized cooling. In addition, the air inlet (return air inlet) and air outlet of each indoor air conditioning unit are fixed in the same location. The indoor air drawn in through the air inlet is mixed with the low-temperature air just discharged through the air outlet, further reducing heat dissipation efficiency and causing significant energy waste, thus increasing the operating costs of the computer room. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent temperature control and energy-saving system for the main control room, which solves the shortcomings of existing temperature control systems that cannot achieve rapid local cooling and have high power consumption when some equipment is operating under high load.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] An intelligent temperature control and energy-saving system for a main control room includes several air conditioning units for cooling. Each air conditioning unit includes an indoor unit and an outdoor unit. The indoor unit is equipped with an air inlet and an air outlet. The system also includes several air inlet and outlet control components located at different positions within the main control room. Each air inlet and outlet control component includes an air inlet duct, an air outlet duct, and a temperature sensor. The air inlets of all the air inlet and outlet control components are connected to the air inlets of the indoor units of each air conditioning unit through air inlet pipes, and each air inlet duct is equipped with an air inlet valve. The air outlet ducts of all the air inlet and outlet control components are connected to the air outlets of the indoor units of each air conditioning unit through air outlet pipes, and each air outlet duct is equipped with an air outlet valve. The temperature sensor is used to monitor the real-time temperature at the location of each air inlet and outlet control component.

[0007] The system also includes a controller configured to: when the air conditioning equipment is running, acquire the real-time temperature of the location of each air inlet and outlet control component, and control the air inlet valve of the air inlet and outlet control component with the lower real-time temperature to open while the other air inlet valves are closed, and control the air outlet valve of the air inlet and outlet control component with the higher real-time temperature to open while the other air outlet valves are closed.

[0008] A further improvement is that the controller is further configured to: when the air conditioning equipment is running, acquire the real-time temperature of the location of each air inlet and outlet control component, and control the air inlet valve of the air inlet and outlet control component with the lowest real-time temperature to open while the other air inlet valves are closed, and control the air outlet valve of the air inlet and outlet control component with the highest real-time temperature to open while the other air outlet valves are closed.

[0009] A further improvement is that the controller is further configured to: when the air conditioning equipment is running, acquire the real-time temperature of the location of each air inlet and outlet control component, obtain a dataset of real-time temperatures, and control the air inlet valves of the air inlet and outlet control components whose real-time temperature is lower than the median of the dataset and whose difference from the median is greater than a set value to open while the other air inlet valves are closed; and control the air outlet valves of the air inlet and outlet control components whose real-time temperature is higher than the median of the dataset and whose difference from the median is greater than a set value to open while the other air outlet valves are closed.

[0010] A further improvement is that if the difference between the mean and the median of the data set that is lower than the data set's median is less than a set value, then the air inlet valve in the air inlet / outlet control component that controls the real-time temperature to be lower than the data set's median will be opened while the other air inlet valves will be closed; if the difference between the mean and the median of the data set that is higher than the data set's median is less than a set value, then the air outlet valve in the air inlet / outlet control component that controls the real-time temperature to be higher than the data set's median will be opened while the other air outlet valves will be closed.

[0011] A further improvement is that the set value is 3℃.

[0012] A further improvement is that the system also includes an air inlet manifold and an air outlet manifold. One side of the air inlet manifold is connected to each air inlet duct through an air inlet pipe, and the other side is connected to the air inlet of each indoor unit of the air conditioning equipment through an air inlet pipe. One side of the air outlet manifold is connected to each air outlet duct through an air outlet pipe, and the other side is connected to the air outlet of each indoor unit of the air conditioning equipment through an air outlet pipe.

[0013] The beneficial effects of this invention are as follows:

[0014] (1) When the system is running, all air conditioners work together, the indoor units take in and take out air in a unified manner, and the incoming air automatically selects low-temperature indoor air. With the further cooling of the condenser, it can quickly form even lower-temperature air. The outgoing air is automatically targeted at high-temperature areas indoors. This can achieve local rapid cooling, and can cool down point by point according to the degree of urgency, from high to low temperature. It is very suitable for solving the problem of local overheating that is easy to occur in the main control room.

[0015] (2) The system keeps the load of each air conditioner the same during operation, avoiding the phenomenon of severe aging of some air conditioners and reduced lifespan, and making it easier to manage and maintain them in a unified manner.

[0016] (3) When the system is running, the air inlet and outlet positions of all indoor air conditioning units are always automatically separated, so there will be no situation where the air inlet is mixed with the air just discharged, thus avoiding the reduction of heat dissipation and the loss of power, achieving the effect of energy saving and reducing the operating cost of the computer room.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Combination Figure 1-2 As shown, a main control room intelligent temperature control and energy-saving system includes several air conditioning units for cooling. The number of air conditioning units is set according to the size requirements of the computer room. Each air conditioning unit includes a conventional indoor unit and an outdoor unit. The indoor unit is equipped with an air inlet and an air outlet. The indoor unit draws in indoor air, cools it through a condenser, and then exhausts it back into the room. The system also includes several air inlet and outlet control components located at different positions in the main control room. Each air inlet and outlet control component includes an air inlet duct, an air outlet duct, and a temperature sensor. The air inlets of all air inlet and outlet control components are connected to the air inlets of each indoor unit of the air conditioning unit through air inlet pipes. Each air inlet duct is equipped with an air inlet valve. The air outlets of all air inlet and outlet control components are connected to the air outlets of each indoor unit of the air conditioning unit through air outlet pipes. Each air outlet duct is equipped with an air outlet valve. Both the air inlet valve and the air outlet valve are electrically controlled valves, which can be automatically controlled. The temperature sensor is used to monitor the real-time temperature at the location of each air inlet and outlet control component.

[0021] The system also includes a controller configured to: when the air conditioning equipment is running, acquire the real-time temperature of the location of each air inlet and outlet control component, and control the air inlet valve of the air inlet and outlet control component with a low real-time temperature (one or more of the lowest temperatures among all air inlet and outlet control components) to open while the other air inlet valves are closed, and control the air outlet valve of the air inlet and outlet control component with a high real-time temperature (one or more of the highest temperatures among all air inlet and outlet control components) to open while the other air outlet valves are closed.

[0022] In practical control, two approaches can be taken:

[0023] Option 1: The controller is further configured to: when the air conditioning equipment is running, acquire the real-time temperature of the location of each air inlet and outlet control component, and control the air inlet valve of the air inlet and outlet control component with the lowest real-time temperature to open while the other air inlet valves are closed, and control the air outlet valve of the air inlet and outlet control component with the highest real-time temperature to open while the other air outlet valves are closed.

[0024] For example, the main control room has five sets of air intake and exhaust control components. The temperatures detected by the temperature sensors are: 1#: 40.5℃; 2#: 48.5℃; 3#: 38.5℃; 4#: 40.2℃; 5#: 41.5℃. In this case, the air intake valve in the 3# air intake / exhaust control component opens, while the air intake valves in 1#, 2#, 4#, and 5# close. Similarly, the air outlet valve in the 2# air intake / exhaust control component opens, while the air outlet valves in 1#, 3#, 4#, and 5# close. This way, all indoor units of the air conditioning equipment draw in low-temperature air through the air intake duct of the 3# air intake / exhaust control component. After further cooling by the condenser, the air is then discharged through the air outlet duct of the 2# air intake / exhaust control component, cooling the high-temperature area where the 2# air intake / exhaust control component is located. As the system operates, the controller will adaptively adjust the air intake and exhaust positions.

[0025] As can be seen, this scheme always draws in only the air with the lowest temperature and exhausts only the air with the highest temperature, which is suitable for rapid local cooling in emergency situations.

[0026] Option 2: The controller is further configured to: acquire the real-time temperature of each air inlet / outlet control component during air conditioner operation, obtain a real-time temperature dataset, and control the air inlet valves of air inlet / outlet control components whose real-time temperature is lower than the median of the dataset and whose difference from the median is greater than a set value to open while the other air inlet valves are closed; control the air outlet valves of air inlet / outlet control components whose real-time temperature is higher than the median of the dataset and whose difference from the median is greater than a set value to open while the other air outlet valves are closed. Additionally, if the difference between the real-time temperature in the dataset that is lower than the median and the median is less than a set value, then control the air inlet valves of the air inlet / outlet control components whose real-time temperature is lower than the median to open while the other air inlet valves are closed; if the difference between the real-time temperature in the dataset that is higher than the median and the median is less than a set value, then control the air outlet valves of the air inlet / outlet control components whose real-time temperature is higher than the median to open while the other air outlet valves are closed.

[0027] For example, the main control room has five sets of air intake and exhaust control components. The temperatures detected by the temperature sensors are: 1#: 40.5℃; 2#: 42.3℃; 3#: 44.6℃; 4#: 46.2℃; 5#: 48.9℃. The median of the dataset is 44.6℃. If the set value is 3℃, then the air intake valve in the 1# air intake / exhaust control component will open, while the air intake valves in 2#, 3#, 4#, and 5# will close. Conversely, the air exhaust valve in the 5# air intake / exhaust control component will open, while the air exhaust valves in 1#, 2#, 3#, and 4# will close.

[0028] For example, the main control room has five sets of air intake and exhaust control components. The temperatures detected by the temperature sensors are: 1#: 40.5℃; 2#: 40.3℃; 3#: 41.6℃; 4#: 48.2℃; 5#: 42.9℃. The median of the dataset is 41.6℃. If the set value is 3℃, then the air intake valves in the air intake and exhaust control components 1#, 2#, 3#, and 5# will be opened, while the air intake valve in component 4# will be closed. Conversely, the air exhaust valve in the air intake and exhaust control component 4# will be opened, while the air exhaust valves in components 1#, 2#, 3#, and 5# will be closed.

[0029] For example, the main control room has five sets of air intake and exhaust control components. The temperatures detected by the temperature sensors are: 1#: 44.9℃; 2#: 44.4℃; 3#: 45.6℃; 4#: 43.2℃; 5#: 46.9℃. The median of the dataset is 44.9℃. If the set value is 3℃, then the air intake valves in the 2# and 4# air intake and exhaust control components will open, while the air intake valves in the 3# and 5# air intake and exhaust control components will close. Conversely, the air exhaust valves in the 3# and 5# air intake and exhaust control components will open, while the air exhaust valves in the 2# and 4# air intake and exhaust control components will close.

[0030] It can be seen that the solution is more rational and smoother. It can adaptively control the number of air inlets and outlets open according to specific conditions. When the temperature in a certain position is abnormally high while the temperature in other positions is low and the difference is not significant, the number of air inlets can be increased. When the temperature in multiple positions is abnormally high, the number of air outlets can be increased to cool down the air.

[0031] Preferably, the system further includes an air inlet manifold and an air outlet manifold. One side of the air inlet manifold is connected to each air inlet duct through an air inlet pipe, and the other side is connected to the air inlet of each indoor unit of the air conditioning equipment through an air inlet pipe. One side of the air outlet manifold is connected to each air outlet duct through an air outlet pipe, and the other side is connected to the air outlet of each indoor unit of the air conditioning equipment through an air outlet pipe.

[0032] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
