Precision air conditioning, also known as constant temperature and humidity machine, is a specialized air conditioning system for computer rooms that precisely controls the temperature and humidity of the environment. It is not only a simple refrigeration system, but combined with a precision microprocessor control system, it can also comprehensively control the environmental temperature, humidity, air cleanliness, and air distribution. Equipped with high-efficiency air filtration devices, electrode vapor humidifiers, and electric heaters.
The difference between them:
1. Traditional comfort air conditioners are mainly designed for homes, offices, hotels, shopping malls, and other places, targeting people with low air supply and dehumidification while cooling; Therefore, comfort air conditioning will cause low humidity in computer rooms, leading to the accumulation of static electricity on the surfaces of electronic components inside the computer equipment, discharge damage to the equipment, interference with data transmission and storage, and a significant increase in energy consumption due to about 50% of the energy being used for dehumidification; Specialized precision air conditioning overcomes some of the drawbacks of comfort air conditioning by using technologies such as controlling the evaporation pressure inside the evaporator and making the surface temperature of the evaporator higher than the dew point temperature.
2. Comfortable air conditioning has low air volume and wind speed, and can only circulate local airflow in the supply direction. It cannot form an overall airflow circulation in the computer room, resulting in uneven cooling and regional temperature differences; The precision air conditioning system specifically designed for computer rooms has high air speed, which creates a comprehensive airflow circulation within the room, ensuring that all equipment receives good cooling.
3. Due to the long-term operation and long working hours of most equipment in computer rooms, air conditioning equipment is required to have high reliability. Comfort air conditioning is difficult to meet the requirements, especially in winter. In cold northern regions, due to low outdoor temperatures, comfort air conditioning cannot operate normally. However, precision air conditioning for computer rooms can ensure normal operation through controllable outdoor unit condensers.
4. Comfort air conditioning cannot accurately control the temperature and humidity inside the computer room, making it difficult to control. Therefore, it cannot meet the needs of computer rooms. However, precision air conditioning specifically designed for computer rooms can accurately control the temperature and humidity inside the room due to its specialized humidification system, efficient dehumidification system, and electric heating compensation system.
5. The length of service life is another important difference between precision air conditioning and comfort air conditioning in computer rooms. The design life of precision air conditioning is generally 10-15 years, with an average time between failures of over 100000 hours, while the design life of comfort air conditioning is 5-8 years, with an uninterrupted service life of 3-5 years throughout the year.
