The constant temperature and humidity air conditioning system refers to the air conditioning system required for temperature and humidity cleanliness. The constant temperature and humidity air conditioning system consists of controller, man-machine interface, frequency converter, temperature sensor, temperature and humidity sensor, water valve actuator, damper actuator, high temperature circuit breaker and air pressure switch.

Constant temperature and humidity air conditioning system principle:
-

The constant temperature and humidity workshop refers to an air environment that maintains a certain temperature and humidity indoors and allows a certain range of fluctuations in temperature and humidity, such as a measuring room, a three-coordinate laboratory, a precision instrument manufacturing and an assembly shop. Some constant temperature and humidity laboratories require high temperature and humidity precision, and some manufacturing rooms and assembly rooms have lower requirements for temperature and humidity accuracy. In addition to the stricter requirements on temperature, the constant temperature and humidity workshop generally has a certain degree of requirements for the humidity, cleanliness of the air, and the noise reduction and vibration resistance of the equipment.

The indoor environment of the constant temperature and humidity workshop is mainly controlled by the air circulation system:
-
-
1. It is very important to calculate the indoor heat and humidity load, and there is also a requirement for the distribution of indoor heat and humidity sources. If the heat source is concentrated, it will have a greater impact on the temperature distribution of the whole room, so heat dissipation should be avoided as much as possible. Larger devices are centrally located.
-
2. The choice of airflow organization, for systems with accuracy requirements above 0.5~2 °C, generally adopts the form of sending up and down. For systems with accuracy requirements below 0.5 °C, it is recommended to use a laminar flow return air type, generally using a ceiling plate for air supply and floor return air.
-
3. Meet the number of air cycles, the higher the accuracy requirement, the higher the number of air cycles.

The constant temperature constant temperature workshop air conditioner is different from the general central air conditioning project. The general central air conditioner is generally a comfortable air conditioner, which does not require high temperature and humidity to meet the comfortable environment required for the human working life. Therefore, constant temperature constant temperature air conditioners generally have functions such as refrigeration, dehumidification, heating, and humidification. The constant temperature and humidity workshop air conditioning system is mainly composed of air conditioning host system, white iron duct engineering, pipeline insulation system, tuyere valve parts, automatic temperature and humidity control.
