The constant temperature and humidity air conditioner has the functions of cooling throughout the year, providing electric heating, hot water heating, steam heating, and introducing some fresh air. Suitable for high-level laboratories, purification workshops, advanced computer rooms and other places. Most people don't know much about it. Next, I will share with you the introduction of the constant temperature and humidity air conditioner and its product features for the reference of friends who want to know the constant temperature and humidity air conditioner.
I. Introduction of constant temperature and humidity air conditioner
The constant temperature and humidity air conditioner is a type of process air conditioner. Generally, the air conditioner that strictly controls indoor temperature and humidity fluctuations and regional deviation control is called constant temperature and humidity air conditioner. Constant temperature and humidity are widely used in electronics, optical equipment, cosmetics, medical and health, bio-pharmaceutical, food manufacturing, various types of measurement, testing and laboratory industries.
The constant temperature and humidity air conditioner is a professional air purification equipment. The non-professionals are not aware of it. When selecting the equipment, it is often selected according to the area of ​​the dehumidification site. Constant temperature and humidity machine use places (such as high-level laboratories, purification workshops, etc.) have strict requirements on the temperature and humidity fluctuation range of their equipment.
Therefore, the constant temperature and humidity air conditioner can not be selected according to the area of ​​the use place, and the professional constant temperature and humidity air conditioner supplier is selected according to the overall wet load of the place of use. Specifically, the total enthalpy difference, unit time dehumidification/humidification amount, and cooling capacity are calculated based on comprehensive factors such as area, layer height, initial humidity value target humidity value, indoor airtightness, wet source, and fresh air supply. / Key parameters such as heat generation, comprehensive selection and matching of constant temperature and humidity air conditioners.
Second, the characteristics of constant temperature and humidity air conditioner
1, annual refrigeration
Because the heat generated by the equipment room is very large, some IDC machine rooms generate more than 30 kw/m2 of heat, so the whole year is cooling. One point to mention here is that the computer room air conditioner also has a heater, which is only activated when dehumidifying. The air outlet temperature should be relatively low for dehumidification, and the room temperature should not be lowered too quickly (the room temperature requirement does not exceed 1 °C every 10 minutes, and the humidity does not exceed 5% per hour).
2, high apparent heat ratio
The sensible heat ratio is the ratio of the amount of sensible cooling to the total amount of cooling. The total cooling capacity of the air conditioner is the sum of the sensible cooling capacity and the submerged cooling capacity, wherein sensible cooling is used to cool down, and latent cooling is used to dehumidify. The heat in the equipment room is mainly sensible heat, so the sensible heat of the air conditioner in the computer room is relatively high, generally above 0.9 (the average comfortable air conditioner is only about 0.6). The large air volume and small air gap are the essential differences between computer room air conditioners and other air conditioners. With a large amount of air, the temperature of the air outlet can be kept too low, and the number of air changes in the equipment room can be increased, which is advantageous for both the operation of the server and the computer. If the temperature of the equipment room changes too much in a short time, the server operation error will occur. The humidity in the equipment room will be too low, which will cause static electricity (the static electricity can reach 10,000 volts when the humidity is 20%).
3. Energy efficiency ratio
Energy efficiency ratio (COP) Even if the conversion ratio between energy and heat, 1 unit of energy is converted into 3 units of heat, COP = 3. Since most of the computer room air conditioners use scroll compressors (the minimum power is also 2.75 kW), the COP can reach 5.6. The energy efficiency ratio of the whole machine is above 3.0.
Through the above introduction, we must have more understanding of the constant temperature and humidity air conditioner and its product features. If you want to know more about constant temperature and humidity air conditioners, please continue to pay attention to the decoration home network.
