Description
Technical Field
The invention relates to a ventilation system, and belongs to the field of ventilation and refrigeration equipment.
Background
Along with the rapid development of the economy in China, the social public utility is also gradually changed into informatization and technological process. The development of the data processing business demands brings about explosive growth of the data processing business demands and leaping development of computer and network technologies, large enterprises and government institutions such as banks, securities, insurance and the like, medical and health, transportation and the like gradually establish data centers with different scales, and under the common promotion of the data processing business demands and technologies, the construction of the data processing centers in China has been advanced into the period of high-speed development. At present, the heat density of novel rack-mounted servers and blade-type servers which are widely adopted in high-density data processing centers is up to 20-30 kw/cabinet, so that not only are the requirements on equipment and technology for data processing, but also higher requirements are put on the running environment of the equipment.
In addition, the energy consumption of the air conditioner of the base station is a 'large household' of the energy consumption of the base station, most of the base stations are unattended at present, but various electronic equipment in the communication base stations can normally operate for a long time under a certain temperature environment (the base station environment national standard GB50174-93 prescribes the base station temperature to be 18-28 ℃ for a long time).
In order to reach the standard environment temperature of the base stations, each communication base station is provided with an air conditioner, and the air conditioners are in a starting state for a long time, so that a large amount of electric energy can be consumed, the power consumption of the communication industry in China reaches hundreds of billions, wherein the power consumption of the communication base station accounts for 45%, and the communication base station becomes the primary part of energy conservation and consumption reduction in the future. With the increase of the electric power cost, the electric charge expenditure of the machine room of the base station is gradually increased along with the increase of the electric power cost, and according to the data display, the annual electric charge expenditure of the base station in a certain area is as much as 2.5 ten thousand yuan, and the proportion of the electric charge expenditure of the air conditioner of the base station is larger. According to statistical analysis, the average electricity charge expenditure of each base station air conditioner accounts for about 54% of the electricity charge expenditure of the whole base station, and the air conditioner becomes main power consumption equipment in a base station room. The communication network in China currently has tens of thousands of main switching devices and nearly millions of base stations, so that if effective and proper measures are taken, the base stations have great potential for energy conservation and emission reduction, and the effect will be very obvious.
Energy conservation and emission reduction are arranged as a basic national policy in China, and the energy utilization efficiency (PUE) value of the newly built large cloud computing data center is required to be superior to 1.5 in the comprehensive working scheme of energy conservation and emission reduction in China. The air heat energy is utilized to solve the energy demand of the building. The energy-saving design of high-temperature environments such as a big data center, a machine room, a base station, a high-temperature workshop and the like is provided with new challenges.
The natural cold source is an inexhaustible large free cold source for human beings in nature vouchsafe, and mainly refers to low-temperature water and air. The region of China is wide, spans six temperature zones, is divided into five building climate zones, namely severe cold, summer heat, winter warm and mild zones, has various climate forms and is well-defined in most of four seasons. For cold areas, the content of outdoor natural cold sources is more abundant, especially in the transition period of winter and autumn and winter and spring; meanwhile, the method has the characteristics of large temperature difference in the morning and evening, long time of day low temperature and the like, and is more suitable for being applied to outdoor natural cold sources.
Refrigerating by utilizing natural cold source is one of the energy-saving ways which rapidly develops in recent years. At present, a fresh air cooling mode is adopted in some places, fresh air is directly introduced for cooling, and outdoor cold air is directly fed into a room by using a fan to achieve the aim of cooling, which is also called natural cooling. The method is characterized in that a temperature and humidity detector is used for detecting the temperature and humidity conditions of indoor and outdoor air, when the outdoor temperature is lower than a certain set value, a fresh air fan is started, cold air outside a machine room is fed into a room, after heat exchange is carried out with indoor hot air, the indoor temperature is reduced, and the heat exchanged hot air is discharged into the room by means of positive pressure or an exhaust fan. The cooling effect of this approach depends on the condition of the outdoor air, typically in conjunction with the original indoor air conditioning unit during the transitional season.
In the fresh air cooling mode, the following defects exist in the direct fresh air cooling:
1. The mode of directly introducing outdoor fresh air into the room can effectively reduce the indoor temperature, but because factors such as dust content and humidity of outdoor air cannot be guaranteed, the quality of the indoor air can be damaged when the outdoor air is cooled down, and indoor equipment, especially some precision equipment, is influenced, and the indoor equipment must be operated in a specific temperature and humidity environment, otherwise the service life of the equipment is reduced, and even safety accidents are caused.
2. In the indoor space where the fresh air cooling mode is installed, thick dust is often covered on equipment and in the indoor space. At present, with the development of urban, more and more base stations and data centers are built around the city, and air generally cannot meet the requirement of directly introducing air into a cooling room, so that the quality of fresh air becomes a factor to be considered.
3. The direct introduction of fresh air can reduce the indoor temperature, but also has an influence on the moisture content of indoor air, especially outdoor cold air which is dried at low temperature in winter in northern severe cold or cold areas. In order to meet the indoor humidity requirement, electrode type humidification is generally adopted. Since the indoor air supply temperature cannot be lower than the dew point temperature of the indoor air, the outdoor air is first heated. In severe cold or cold areas, outdoor cold air is directly introduced to cool the indoor, and the problem of heating and humidifying fresh air must be solved, otherwise, energy cannot be saved, and the energy consumption of an original air conditioning system may be increased.
4. If the air is directly sent into a room, dew condensation is likely to occur in the air supply pipeline and the air inlet and even on the surface.
The natural circulation separated heat pipe technology is that when the outdoor air temperature is lower than the indoor temperature and reaches a certain degree, the separated heat pipe is utilized to enable the indoor hot air and the outdoor cold air to exchange heat, the cold air takes away the indoor heat and does not contact with the indoor hot air, the cold air and the hot air only exchange heat, and the humidity and the cleanliness of the indoor air are easy to control, so that the air quality of a machine room and other places can be ensured.
In view of the foregoing, it is desirable to provide an intelligent energy-saving ventilation system, which can save energy and reduce emission while ensuring the indoor working temperature of a base station.
