Guide to the purchase of constant temperature and humidity air conditioners.

Speaking of air conditioning, we are all familiar with it. Basically, air conditioners are used at home and at work, but do you know what kind of air conditioners are at constant temperature and humidity? Constant temperature and humidity air conditioner, also called precision air conditioning, is relatively rare in life. Room precision air conditioning is widely used in high-precision environments such as computer rooms, program-controlled exchange rooms, satellite mobile communication stations, large-scale medical equipment rooms, laboratories, test rooms and precision electronic instrument production workshops. Such an environment requires high indexes such as air temperature, humidity, cleanliness, air distribution, etc. It must be provided by precision air conditioning equipment and run safely and reliably 24 hours a day, 365 days a year.

Constant temperature and humidity air conditioning brand: constant temperature and humidity air conditioners are basically used in laboratories? There are basically no household ones, but the price is super expensive. The main brands are as follows.

The brands of constant temperature and humidity air conditioners used in computer rooms are relatively strong, such as LIBERTY, STULZ, RC, ICAIR, CANTAL and Helos.

The traditional comfort air conditioner is mainly designed for people, with small air supply volume and large air supply volume difference, and refrigeration and dehumidification are carried out at the same time, while the built-in heat in the computer room accounts for more than 90% of the total heat, including the heat generated by the equipment itself, the heat generated by lighting, the heat conducted through walls, ceilings, windows and floors, the radiation heat of sunlight, the heat penetrating the Phoenix and the New Phoenix through gaps, etc. The residual humidity generated by these calorific values is very small, so comfortable air conditioning will inevitably lead to low relative humidity in the machine room, which will accumulate static electricity on the surface of circuit components inside the equipment, damage the equipment and interfere with data transmission and storage. At the same time, because (40%-60%) of the refrigeration capacity is consumed in dehumidification, the refrigeration capacity of the actual cooling equipment is greatly reduced, and the energy consumption is greatly increased. In the design of constant temperature and humidity air conditioning, the evaporation pressure in the evaporator is strictly controlled, and the surface temperature of the evaporator is higher than the dew point temperature of non-dehumidified air by increasing the air supply. All the generated cold energy is used to reduce the temperature, which improves the working efficiency and reduces the water loss, that is, the enthalpy difference of air supply is reduced due to the large air supply volume.

Comfort air conditioner has small air volume and low wind speed, and can only circulate locally in the direction of air supply, which cannot form the overall air circulation in the machine room. The uneven cooling of the machine room leads to large temperature difference in the machine room area, low temperature in the air supply direction and high temperature in other areas. Heating equipment will accumulate local heat due to different placement positions, leading to overheating and damage of the equipment. However, the special air conditioner for the machine room has a large air supply and high air exchange rate (generally 30-60 times/hour), which can form an overall air circulation in the whole machine room and make all the equipment in the machine room cool evenly.

The traditional comfort air conditioner, because of the small air supply volume and less air exchange times, the air in the machine room can't ensure the high enough flow rate to bring dust back to the filter screen, which produces deposits in the equipment in the machine room and has adverse effects on the equipment itself. The filtration performance of comfortable air conditioning unit is poor, which can not meet the purification requirements of computer. The special air conditioner in the machine room has large air supply and good air circulation. At the same time, due to the special air filter, the dust in the air can be filtered out in time and efficiently, and the room can be kept clean.

The constant temperature and humidity air conditioner is also equipped with special humidification system, high efficiency dehumidification system and electric heating compensation system. Through the microprocessor, the temperature and humidity in the computer room can be accurately controlled according to the data fed back by various sensors. However, the comfortable air conditioner is not equipped with humidification system, which can only control the temperature, with low accuracy and difficult humidity control, and cannot meet the needs of equipment in the computer room.

Constant temperature and humidity air conditioner can effectively control temperature, humidity and cleanliness, and has the functions of high efficiency, energy saving, low noise and environmental protection. It can be widely used in electronics, optical equipment, cosmetics, medical care, biopharmaceuticals, food manufacturing, various metrology, testing and laboratory industries.
