With the improvement of people's quality of life, the application of air conditioners is very extensive. Everywhere we go there will be air conditioners. Households, shopping malls, and places where we go to work need air conditioners. Now the brand of air conditioners is coming. The more, too many air-conditioning brands are dazzling, so please follow the decoration of the small series to understand the special air conditioning in the Daikin room . What are the characteristics of the special air conditioner in Daikin machine room? 1, the significant heat: Computers installed in the equipment room, peripherals, servers, switches, optical transceivers, and other power equipment, such as UPS power supplies, will radiate heat to the equipment room in the form of heat transfer, convection, and radiation. These heats only cause temperature in the equipment room. The rise is sensible. A server cabinet has a heat dissipation of several kilowatts to ten kilowatts per hour. If a blade server is installed, the heat dissipation will be higher. The heat dissipation capacity of large and medium-sized computer rooms is around 400W/m2, and the data center with higher installed density may reach 600W/m2 or more. The sensible heat ratio in the equipment room can be as high as 95%. 2, the amount of wind is large: The heat of the equipment is transmitted to the equipment room through conduction and radiation. The heat generated by the densely packed areas of the equipment is concentrated. In order to make the temperature and humidity of each area in the equipment room uniform, and the control is within the allowable base and fluctuation range, a larger The air volume takes away the excess heat. The potential heat in the equipment room is less, generally no dehumidification is required. When the air passes through the evaporator of the air conditioner, it does not need to fall below the zero temperature. Therefore, the temperature difference between the air supply and the enthalpy difference is small. In order to move the residual space in the engine room, it needs to be larger. Air supply. 3. Uninterrupted operation: The heat dissipation of the equipment in the equipment room is a steady-state heat source. It runs continuously throughout the year. This requires an uninterrupted air-conditioning protection system. It also has high requirements for the power supply of air-conditioning equipment. It requires not only two-way mutual power investment. Moreover, for the air conditioning system that guarantees important computer equipment, there should be a generator set as a backup power source. Long-term steady-state heat sources cause refrigeration even in winter rooms, especially in the South. In the northern region, if refrigeration is still needed in winter, when selecting an air conditioning unit, it is necessary to consider the condensing pressure of the unit and other related problems, and increase the proportion of outdoor cold air intake to achieve energy saving. 4, high cleanliness The computer room has strict air cleanliness requirements. Dust and corrosive gases in the air can seriously damage the life of electronic components, and cause poor contact and short circuit. Therefore, the air conditioner for the equipment room can be used to dedust and filter the circulating air according to relevant standards. It is necessary to add fresh air to the equipment room and maintain a positive pressure in the equipment room. According to the regulations, the dust concentration in the main room is tested under static conditions. The number of dust particles greater than or equal to 0.5 m per liter of air should be less than 18,000. The pressure difference between the main room and other rooms and corridors should not be less than 4.9Pa, and the difference between the outdoor static pressure should not be less than 9.8Pa. Now everyone has a good understanding of the air conditioning in Daikin room. I hope that these contents can help you. If you want to know more about decoration, please continue to pay attention to the decoration home network.
