Description

Technical Field

[0001] This utility model relates to the field of fresh air cooling technology, and in particular to a fresh air cooling system for a control room. Background Technology

[0002] A control room generally refers to a room used by telecommunications, network, mobile, dual-line, power, and government or enterprise entities to house servers and provide IT services to users and employees. Control rooms typically house various servers and minicomputers. Because servers and minicomputers generate heat during operation, proper ventilation and heat dissipation are crucial in control rooms.

[0003] For example, a fresh air cooling system with authorization announcement number CN215809067U, by installing an indoor return air valve and equipping it with a temperature sensor on the upper part of the cooling box, along with an outdoor air inlet valve on the back of the cooling box and a fan inside the cooling box, allows the device to adjust the opening and closing of the indoor return air valve and the outdoor air inlet valve according to the indoor return air temperature and the outlet air temperature, and intelligently adjust the fan speed according to the indoor temperature, resulting in good energy-saving effect. However, in order to detect the indoor air temperature, the system has an intelligent indoor return air valve, but the indoor return air and the outdoor air inlet enter the fan at the same time. At this time, the inlet air temperature has increased, and then it is blown into the room by the fan, resulting in insufficient cooling effect. In addition, the outdoor air inlet needs to circulate in the cooling box before being blown into the room by the fan, resulting in a long air guide path and a lot of fan power being wasted on the air guide path, which will waste a lot of energy in long-term use. To address this, a control system for fresh air cooling in computer rooms is proposed as an improvement. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a control room fresh air cooling system to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a control room fresh air cooling system, including a housing; an inspection door is provided on one side of the housing, a blower is provided at the bottom of the housing, a filter is provided behind the blower, an outdoor air inlet valve is provided outside the filter, an air outlet is provided on the front side of the blower, a partition is fixedly connected to the middle of the housing, a controller is provided on the partition, an exhaust fan is provided diagonally above the controller, an exhaust vent is provided outside the exhaust fan, an indoor return air valve is provided on the top plate of the housing, and a control panel and a display screen are provided on one side of the housing.

[0007] Preferably, as described in any of the above embodiments, the inspection door is provided with a handle, and the blower is provided with a bracket below it that is fixedly connected to the housing.

[0008] Preferably, in any of the above solutions, the air outlet and the outdoor air inlet valve are respectively arranged, and both the air outlet and the outdoor air inlet valve are located below the partition.

[0009] The above technical solution employs the following: The enclosure houses the cooling device and provides some protection for its internal structure. A side access door facilitates maintenance of the internal structure, and a handle on the door allows for easy opening. A support frame supports the blower, ensuring its stability during operation. The blower delivers cool outdoor air to the control room to cool it and ensure the normal operation of the motor components. A filter filters the outdoor air, preventing larger particles from entering the control room. An outdoor air inlet valve regulates the opening of the outdoor air inlet. An outlet pushes the cool outdoor air through the blower into the control room. The outlet and outdoor air inlet valve are positioned correspondingly to minimize the path of the cool outdoor air, improving the blower's efficiency.

[0010] Preferably, temperature sensors are provided on the sides of both the air outlet and the indoor return air valve, according to any of the above solutions.

[0011] Preferably, in any of the above solutions, the controller is fixedly mounted on a partition, which divides the housing into two relatively airtight spaces.

[0012] The above technical solution employs the following: Temperature sensors detect the air temperature at the installation location and relay the results to the controller. Temperature sensors are installed on the sides of the air outlet and the indoor return air valve, allowing both the outlet and return air temperatures to be sensed. This temperature-sensing mechanism adjusts the valve's opening and closing accordingly. A partition supports the controller and divides the enclosure into two relatively airtight spaces, ensuring that the indoor return air and outdoor intake air are in separate, mutually airtight compartments. This prevents the outdoor intake air temperature from being affected by the indoor return air temperature, thereby improving cooling efficiency. The controller controls the electrical components and displays their operating status on a screen for operator monitoring.

[0013] Preferably, in any of the above embodiments, the exhaust fan is fixed to the side wall of the housing, and the exhaust port is located above the outdoor air inlet valve.

[0014] Preferably, the controller is electrically connected to the blower, outdoor air inlet valve, temperature sensor, exhaust fan, indoor return air valve, control panel, and display screen.

[0015] The above technical solution employs an exhaust fan to provide kinetic energy for the indoor return air, and an exhaust vent to discharge the indoor return air outdoors, further improving the cooling efficiency of the device. The exhaust vent and outdoor air inlet valve are located on the same side; during installation, this side can be positioned closer to the outdoors for ease of installation by staff. The indoor return air valve guides warm air from the control room into the enclosure for the temperature sensor to detect the indoor temperature. When the temperature sensor detects that the indoor return air temperature is higher than the set value, the controller controls the outdoor air inlet valve and the indoor return air valve to open to a greater angle. Simultaneously, the supply and exhaust fans increase their speed, accelerating the introduction of outdoor cold air and the discharge of indoor warm air, thereby improving cooling efficiency.

[0016] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0017] 1. This control room fresh air cooling system utilizes a partition in the middle of the enclosure. Below the partition are a blower, filter, outdoor air inlet valve, and air outlet. Above the partition are a controller, exhaust fan, exhaust outlet, and indoor return air valve. When the temperature sensor detects that the indoor return air temperature is higher than a set value, the controller opens the outdoor air inlet valve and indoor return air valve to a greater angle. Simultaneously, the blower and exhaust fan increase their speed, accelerating the introduction of cool outdoor air and the exhaust of warm indoor air, thus improving cooling efficiency. The indoor return air and outdoor air inlet are located in two separate airtight spaces, ensuring that the temperature of the outdoor air inlet is not affected by the temperature of the indoor return air, thereby improving cooling efficiency.

[0018] 2. This control room fresh air cooling system, through the corresponding configuration of the supply fan, filter, outdoor air inlet valve, and air outlet, allows outdoor cold air to enter the enclosure through the outdoor air inlet valve when the supply fan is started. After passing directly through the filter, the supply fan powers the air and discharges it into the control room through the air outlet, thus cooling the control room. The very short conduction path of the outdoor cold air improves the efficiency of the supply fan.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1-4 As shown, this utility model includes a housing 1, an inspection door 2 on one side of the housing 1, a blower 4 at the bottom inside the housing 1, a filter 5 at the rear of the blower 4, an outdoor air inlet valve 6 outside the filter 5, an air outlet 7 at the front of the blower 4, a partition 9 fixedly connected to the middle of the housing 1, a controller 10 on the partition 9, an exhaust fan 11 diagonally above the controller 10, an exhaust port 12 outside the exhaust fan 11, an indoor return air valve 13 on the top plate of the housing 1, and a control panel 14 and a display screen 15 on one side of the housing 1.

[0029] Example 1: A handle is provided on the inspection door 2, and a bracket 3, fixedly connected to the housing 1, is located below the blower 4. The air outlet 7 corresponds to the outdoor air inlet valve 6, both positioned below the partition 9. The housing 1 houses the cooling device and provides some protection for its internal structure. The inspection door 2 on its side facilitates maintenance of the internal structure, and the handle on the inspection door 2 allows for easy opening. The bracket 3 supports the blower 4, ensuring its stability during operation. The blower 4 delivers cool outdoor air to the control room to cool it and ensure the normal operation of the motor components within. The filter 5 filters the outdoor air, preventing larger particles from entering the control room. The outdoor air inlet valve 6 adjusts the opening degree of the outdoor air inlet. Air outlet 7 is used to push outdoor cold air into the control room through the blower 4. Air outlet 7 is set in correspondence with outdoor air inlet valve 6 to make the conduction path of outdoor cold air as short as possible and improve the working efficiency of blower 4.

[0030] Example 2: Temperature sensors 8 are installed on the sides of both the air outlet 7 and the indoor return air valve 13. The controller 10 is fixedly mounted on the partition 9, which divides the housing 1 into two relatively airtight spaces. The temperature sensors 8 can sense the air temperature at their installation location and report the results to the controller 10. The placement of temperature sensors 8 on the sides of the air outlet 7 and the indoor return air valve 13 allows for the sensing of both the outlet and return air temperatures, enabling adjustments to the valve's opening and closing based on temperature. The partition 9 supports the controller 10 and, by dividing the housing 1 into two relatively airtight spaces, ensures that the indoor return air and outdoor intake air are in two mutually airtight spaces, preventing the outdoor intake air temperature from being affected by the indoor return air temperature, thereby improving cooling efficiency. The controller 10 controls the electrical components and displays their operating status on the display screen 15 for operator observation.

[0031] Example 3: The exhaust fan 11 is fixed to the side wall of the housing 1, and the exhaust port 12 is located above the outdoor air inlet valve 6. The controller 10 is electrically connected to the supply fan 4, the outdoor air inlet valve 6, the temperature sensor 8, the exhaust fan 11, the indoor return air valve 13, the control panel 14, and the display screen 15. The exhaust fan 11 provides kinetic energy for the indoor return air, and the exhaust port 12 is used to exhaust the indoor return air to the outside, further improving the cooling efficiency of the device. The exhaust port 12 and the outdoor air inlet valve 6 are located on the same side, and during installation, this side can be placed closer to the outside to facilitate the installation of the cooling system by the staff. The indoor return air valve 13 is used to introduce warm air from the control room into the housing 1 so that the temperature sensor 8 can sense the indoor temperature. When the temperature sensor 8 detects that the indoor return air temperature is higher than the set value, the controller 10 controls the outdoor air inlet valve 6 and the indoor return air valve 13 to open to a larger angle. At the same time, the supply fan 4 and the exhaust fan 11 increase their speed to accelerate the introduction of outdoor cold air and the exhaust of indoor warm air, thereby improving cooling efficiency.

[0032] The working principle of this utility model is as follows:

[0033] S1. Position the side of the housing 1 equipped with the outdoor air inlet valve 6 close to the outside, fix the housing 1, and start the blower 4 and exhaust fan 11 through the control panel 14.

[0034] S2. Outdoor cold air is given kinetic energy by the blower 4 after passing through the outdoor air inlet valve 6 and filter 5, and then enters the control room from the air outlet to cool the control room. Indoor warm air is given kinetic energy by the exhaust fan 11 after passing through the indoor return air valve 13, and is discharged to the outside from the exhaust outlet 12.

[0035] S3. When the temperature sensor 8 detects that the indoor return air temperature is higher than the set value, the controller 10 controls the outdoor air inlet valve 6 and the indoor return air valve 13 to open to a larger angle. At the same time, the supply fan 4 and the exhaust fan 11 increase their speed to accelerate the introduction of outdoor cold air and the exhaust of indoor warm air.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1. This control room fresh air cooling system, by setting a partition 9 in the middle of the enclosure 1, and installing a blower 4, filter 5, outdoor air inlet valve 6, and air outlet 7 below the partition 9, works in conjunction with a controller 10, exhaust fan 11, exhaust outlet 12, and indoor return air valve 13 located above the partition 9. When the temperature sensor 8 detects that the indoor return air temperature is higher than the set value, the controller 10 controls the outdoor air inlet valve 6 and the indoor return air valve 13 to open to a greater angle. At the same time, the blower 4 and exhaust fan 11 increase their speed, accelerating the introduction of outdoor cold air and the exhaust of indoor warm air, thereby improving cooling efficiency. The indoor return air and outdoor air inlet are located in two airtight spaces, ensuring that the temperature of the outdoor air inlet is not affected by the temperature of the indoor return air, thus improving cooling efficiency.

[0038] 2. This control room fresh air cooling system, by correspondingly setting up the blower 4, filter 5, outdoor air inlet valve 6, and air outlet 7, allows outdoor cold air to enter the housing 1 through the outdoor air inlet valve 6 when the blower 4 is started. After passing directly through the filter 5, it is powered by the blower 4 and discharged from the air outlet 7 into the control room, cooling the control room. The conduction path of the outdoor cold air is very short, improving the working efficiency of the blower 4.
