The Constant Temperature and Humidity Test Chamber is made up of these six systems: controller, humidity, refrigeration, heating, air circulation and the sensor.
Here we mainly focus on the working principles of the systems above.
The Constant Temperature and Humidity Test Chamber
1.Controlling system is the core of constant temperature and humidity test chamber. Some important indicators like heating rate and exactness all depends on it. Controlling system will not go wrong in the process of most cases because it basically belongs to software part.
2.Humidity system actually falls into two parts: humidification system and dehumidification system. Humidification method of constant temperature and humidity test chamber is generally steam humidification. While for dehumidification, there are two ways: mechanical refrigeration dehumidification and desiccant dehumidification.
3.Refrigeration system is the critical part of constant temperature and humidity test chamber. Refrigeration system of the constant temperature and humidity test chamber produced by Linpin consists of two parts: high temperature part and low temperature part, each of which is actually an independent refrigeration system.
4.Heating system is simpler compared with the refrigeration system. It is mainly composed of high-power electric resistance wires because the test chamber has a high requirement of heating rate. As a result, heating system of the test chamber has a relatively large power.
5.Air circulation system is generally made up of centrifugal fan and the motor which drives it. This system makes the air in the test chamber to circulate.
6.Sensors of constant temperature and humidity test chamber include primarily temperature sensor and humidity sensor.
All these above are the six systems of our constant temperature and humidity test chamber.
