main features

1. Constant temperature and humidity air conditioners mainly include air-cooled direct evaporative type DLA/FLA.

To ensure the regulation of cooling capacity, measures such as compressor hot gas bypass and electric heating control are adopted to achieve a constant room temperature.

3. Standard configuration of secondary electric heater with high efficiency and large heat dissipation area, effectively avoiding ionization effect; The stepless adjustable linear heating material equipped with controllable silicon has low inertia and achieves proportional integral control. It has low inertia, rapid heating and cooling, and can quickly achieve the heating purpose,

Automatically adjust the electric heater between 0% and 100% with temperature changes. The electric heater is equipped with a safety thermal protector to ensure safe and stable operation.

4. The standard configuration is a detachable electrode humidifier that quickly produces clean steam without any issues. To meet the national first-class constant temperature and humidity laboratory standard, an electric proportional integral steam humidifier can be equipped. The humidifier has an independent controller and a built-in humidity evaporator,

Realize proportional integral humidification with precise control; Equivalent configuration with dual dehumidification systems to achieve constant humidity control.

5. Ordinary tap water can achieve a humidification accuracy of ≤± 2% Rh; if fully deionized water is used, the humidity control accuracy can reach ± 1% Rh. The electric proportional integral steam humidifier has a built-in constant temperature system to ensure that the required humidification amount is quickly achieved during the on/off adjustment process.

6. Install internationally advanced high-sensitivity sensors (with an accuracy of ± 1Rh) in a high-precision constant temperature and humidity laboratory; Collect data and perform comprehensive processing to ensure the control accuracy of the constant temperature and humidity system and meet the temperature and humidity requirements of indoor environments.

7. The first level standard constant temperature and humidity air conditioner adopts centralized control of cooling, heating, and dehumidification, and independent control of humidification. Cooling, heating, dehumidification control, and humidification independent control are interrelated and mutually restrictive, and the two control systems work together to achieve precision

Control temperature and humidity.

8. Independent temperature control, mutual compensation between cooling and heating, proportional integral control, precise temperature control.

9. Independent humidity control, mutual compensation between dehumidification and humidification, proportional integral and thyristor control, precise humidity control.

10. The independent temperature control and independent humidity control combined control method completely solves the problem of micro air gaps in ordinary constant temperature and humidity air conditioners for cooling, heating, humidification, and dehumidification. This operating mode can form four continuous operating curves for cooling, heating, humidification, and dehumidification, achieving uninterrupted dynamic balance,

Refine the control of temperature and humidity.

11. Constant temperature and humidity air conditioning truly achieves modularity, with all models of units having the same height and thickness, only differing in width; It can be divided into multiple modules during transportation and installation, making it easy to enter the elevator and pass through narrow passages.

The secondary module of the dual module unit has a backup function. When the main module is not working enough to meet the cooling requirements of the computer room or when the main module fails, the secondary module will work, fully reflecting the role of backup. Under normal operation, the main and auxiliary modules adopt a rotating working mode.

13. There are various ways to supply and return air to the unit. The air supply methods can be divided into upward air supply and downward air supply; There are various ways to return air, including top return, bottom return, front return, and back return.

14. The EU4 level air filter has good filtering effect and meets the cleanliness requirements.

15. Precise intelligent control system. Users can monitor various temperature and humidity parameters and fault operation status information of the unit in real time, and can adjust various parameters after entering passwords.

16. Super strong networking function and remote mobile monitoring function. Supports RS485, RS232, RS422, ModBUS, LonWORKS&BacNET, supports GSM mobile short message components and IP protocol SNMP, and can control up to 16 air conditioning units.

17. R22 can be used as a refrigerant, and R410a or R407c environmentally friendly refrigerants can also be selected.

18. Select components from world-renowned brands to ensure the reliability and high quality of the entire machine.

19. The core component of the refrigeration section adopts a fully enclosed high-efficiency scroll compressor from American Copeland, which has fast starting speed, low noise, and high refrigeration efficiency; The supply fan adopts a well-known brand motor with low noise and high air volume, ensuring air circulation. It is equipped with a high-efficiency evaporator with a large windward area, small enthalpy difference, small temperature gradient, and high accuracy.

The main function adopts a design with high air volume and small enthalpy difference, which automatically controls and adjusts the cooling, heating, humidification, dehumidification, etc. of the laboratory to maintain constant temperature and humidity, ensuring the accuracy of temperature and humidity control in the laboratory and meeting the requirements of the testing environment.

The main applications include fiber inspection, metrological quality inspection, inspection and quarantine, chemical testing, data preservation, dedicated warehouses, military applications, precision processing, and other national level constant temperature and humidity laboratories that require constant high-precision temperature and humidity, as well as precise control of the working environment.
