[0002] Data shows that the number of 5G computer rooms is huge, the growth is rapid, and the installations are scattered across the country. Generally, 5G computer rooms use precision air-conditioning units for cooling or heating, and the PUE value may be as high as 3.0 or above, which means that for every 1W of electricity consumed by the IT equipment in the computer room, the entire computer room actually consumes more than 3W of electricity in total.
[0003] The high energy consumption of 5G equipment rooms has become increasingly prominent, hindering the development of 5G. In order to solve the high energy consumption of 5G, promote green development, and help the country achieve its "dual carbon" goals as scheduled, we use new air, heat pipes and other technical means to increase the proportion of natural cooling sources, so as to achieve less compressor operation throughout the year and save more electricity.
[0004] However, introducing fresh air to cool down the equipment in the computer room will reduce the cleanliness of the computer room due to dust in the air. The fresh air must be filtered, and the filter needs to be replaced regularly, which increases procurement costs and maintenance workload. Utility Model Content

DETAILED DESCRIPTION
[0024] The utility model is further described in conjunction with the following embodiments.
[0025] Depend on Figure 1 It can be seen that the fresh air coupled air conditioning system described in this embodiment includes a fresh air system, a compression air conditioning system and a heat pipe heat dissipation system;
[0026] The fresh air system comprises a fresh air channel 1, an air inlet 11 arranged at one end of the fresh air channel 1, and an air inlet 12 arranged at the other end of the fresh air channel 1;
[0027] The fresh air system further comprises an induced draft fan 2 arranged at the air inlet and a filter arranged in the fresh air passage 1; the fresh air passage 1 is provided with a back-blowing fan between the induced draft fan 2 and the filter.
[0028] Specifically, the fresh air coupled air conditioning system described in this embodiment, by setting up a fresh air system, a compression air conditioning system and a heat pipe cooling system in the machine room, operates in a coupled manner with three temperature control means, which can increase the diversity of choices and achieve the purpose of energy saving; in addition, by setting up an anti-blowing blower, the anti-blowing blower can blow off the dust adhering to the filter, thereby increasing the life of the filter and reducing the number of times the filter is replaced and maintained.
[0029] In the fresh air coupled air conditioning system described in this embodiment, a damper 13 is provided between the air inlet 11 and the fresh air passage 1. The above arrangement facilitates the control of fresh air entering the machine room.
[0030] In the fresh air coupled air conditioning system described in this embodiment, the filter includes a precision filter 31 and a coarse filter 32; the precision filter 31 is arranged at one end close to the air inlet 11; the coarse filter 32 is arranged at one end close to the air inlet 12.
[0031] Specifically, by providing the precision filter 31 and the coarse filter 32 , a double filtering method is provided, thereby enhancing the filtering effect on dust.
[0032] The fresh air coupled air conditioning system described in this embodiment comprises a back-blowing fan 41 disposed between the precision filter 31 and the induced draft fan 2 and a second back-blowing fan 42 disposed between the precision filter 31 and the coarse filter 32 .
[0033] Specifically, through the above-mentioned arrangement, the first back-blowing blower 41 and the second back-blowing blower 42 can respectively pass reverse airflow to the precision filter 31 and the coarse filter 32 , thereby blowing off dust on the precision filter 31 and the coarse filter 32 , thereby increasing the service life of the precision filter 31 and the coarse filter 32 .
[0034] A fresh air coupled air conditioning system described in this embodiment further includes a first pressure difference sensor 51 and a second pressure difference sensor 52;
[0035] The first differential pressure sensor 51 is used to measure the difference between the air pressure between the precision filter 31 and the air inlet 11 and the air pressure between the precision filter 31 and the coarse filter 32;
[0036] The second differential pressure sensor 52 is used to measure the difference between the air pressure between the precision filter 31 and the coarse filter 32 and the air pressure between the coarse filter 32 and the air inlet 12 .
[0037] Specifically, through the above-mentioned settings, by setting the first differential pressure sensor 51 and the second differential pressure sensor 52, the dirtiness and blockage conditions of the precision filter 31 and the coarse filter 32 can be sensed respectively, so that the first back-blowing fan 41 and the second back-blowing fan 42 can be turned on in time to blow away the dust, thereby realizing intelligent dust removal.
[0038] In the fresh air coupled air conditioning system described in this embodiment, an electrostatic dust collector 6 is provided between the precision filter 31 and the coarse filter 32. Through the above arrangement, the electrostatic dust collector 6 can quickly collect dust blown off from the precision filter 31, and can also reduce excessive dust adhesion to the inner side of the coarse filter 32. At the same time, during the opening process of the electrostatic dust collector 6, high voltage electricity can be released to cause air ionization, generating a certain concentration of ozone, and the ozone environment can effectively inhibit the reproduction of microorganisms in the space between the precision filter 31 and the coarse filter 31; and the dust blown off from the coarse filter 32 directly falls to the outside through the air inlet 12.
[0039] The fresh air coupled air conditioning system described in this embodiment further includes an outdoor air quality sensor 71 , an outdoor temperature and humidity sensor 72 , and an indoor temperature and humidity sensor 73 .
[0040] Specifically, this embodiment can detect the air quality by setting up outdoor temperature and humidity sensors and outdoor air quality sensors 71, avoiding the fresh air system from being turned on in windy and dusty weather or extremely high humidity weather, and extending the service life of the fresh air system filter.
[0041] In the fresh air coupled air conditioning system described in this embodiment, the compression air conditioning system includes a compressor 81, an evaporator 82 and a condenser 83 connected by pipelines; the compression air conditioning system also includes an indoor circulation fan 84 provided at the evaporator 82 and a heat dissipation fan 85 provided at the condenser 83. Through the above arrangement, the refrigerant circulates between the evaporator 82 and the condenser 83 to cool the room.
[0042] In the fresh air coupled air conditioning system described in this embodiment, the heat pipe heat dissipation system includes a heat exchange pipe 9 arranged between the evaporator 82 and the condenser 83. The above arrangement can cool down the pipe of the compression air conditioning system, and can also cool down the room directly through the heat exchange pipe 9 when the compression air conditioning system is not working.
[0043] In the fresh air coupled air conditioning system described in this embodiment, valves 43 are provided at both the first anti-blowing air 41 and the second anti-blowing air 42 .
[0044] After the temperature and humidity parameters of the computer room have been stable for a period of time, and the outdoor air quality (calculated by PM100 particle concentration) meets the cleanliness requirements for the start-up of the fresh air system, the outdoor air temperature is lower than the indoor air temperature and meets the set temperature difference value requirements (for example, the outdoor temperature is 2-8°C lower than the indoor temperature), and the humidity meets the requirements, the fresh air system is turned on to fill in fresh air from the outside, replace the higher temperature air in the computer room, and ensure the heat dissipation requirements of the equipment in the computer room.
[0045] During the smooth operation of the fresh air system, the compression air conditioning system is turned off, and the values of the first differential pressure sensor 51 and the second differential pressure sensor 52 are detected. If the value of any differential pressure sensor exceeds the set range, the compression air conditioning system is switched back to the compression air conditioning system, the damper 13 is closed, and the back-blowing fan and the electrostatic dust collection device 6 are started at the same time to blow and clean the precision filter 31 and the coarse filter 32 to extend the maintenance and replacement cycle of the filter.
[0046] When the blower is started too frequently, for example, more than once a day, a fault report is issued to remind maintenance personnel to go to the site for processing.
[0047] When the indoor air temperature is within a reasonable range and the outdoor temperature is much lower than the indoor temperature (for example, the outdoor temperature is more than 10°C lower than the indoor temperature), the fresh air system and the compression air conditioning system are turned off, and only the indoor circulation fan 84 and the outdoor heat dissipation fan 85 are turned on to dissipate heat using the heat pipe system. If the indoor temperature is lower than the minimum setting, the heating cycle of the compression air conditioning system is turned on to make it work in the heating mode to maintain the antifreeze operating temperature of the computer room and prevent the computer room temperature from being too low to affect the normal operation of electronic equipment.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
