With the development of social economy and science and technology, and the acceleration of social industrialization, different fields and places have different functions required for some products, and they need to be constantly met. For example, household air conditioners cannot meet the needs of computer rooms, so high-precision constant temperature and humidity air conditioners are needed. Now the editor of Seth constant temperature and humidity air conditioning system will introduce you to high-precision constant temperature and humidity air conditioners. 
1. Constant temperature and humidity air conditioners use large air volume and low enthalpy difference to maintain a small temperature and humidity uniformity. Ordinary household air conditioners strive for comfort in terms of air supply. The air supply volume of general constant temperature and humidity air conditioners is 2 to 3 times that of ordinary household air conditioners. 
2. Due to the rapid change of humidity, the unit needs to be dehumidified frequently, and the constant temperature and humidity air conditioner adopts refrigeration and dehumidification, so the air conditioning refrigeration system is required to be started frequently, which has very high requirements for the refrigeration system; and the household air conditioner compressor cannot be started frequently, and a three-minute compressor shutdown protection is set.
3. Constant temperature and humidity air conditioners have powerful independent control motherboards, which must have temperature, humidity detection, and airflow detection functions. With the increasing requirements of computer rooms, the control motherboard has gradually added functions such as automatic start-up, fault warning, historical data storage, data output, and network monitoring. However, household air conditioners have few additional functions.

4. Chilled water cooling uses chilled water (designed according to the general central air conditioning water temperature) as a non-cold source. The coil runs ordinary cold water at about 7°C. The computer motherboard easily achieves 0% to 100% stepless adjustment of cooling capacity by controlling the opening of the water valve. Moreover, the integral valve structure is as simple as a household faucet, with a very long service life and trouble-free operation for many years. Furthermore, the enthalpy of water is 1000 times that of air and 800 times that of refrigerant R22. Using chilled water cooling, the maximum inlet and outlet water temperature difference is below 5°C, which more effectively ensures the uniformity and reliability of the air supply temperature. In the direct expansion cooling method, the temperature difference between the front and end of the refrigerant in the coil reaches 10°C. Chilled water type air conditioning units are used for high-precision constant temperature and humidity laboratory air conditioning, with remarkable effects and very low failure rates.
