In recent years, with the rapid increase in demand for product reliability, lifespan, and stability testing in industries such as electronics, materials, pharmaceuticals, and automotive, environmental simulation equipment — including constant temperature and humidity test chambers and temperature-humidity cycling chambers — has become increasingly important. These types of equipment can simulate various temperature and humidity environments, assisting manufacturers in quality verification, life testing, and material weather resistance evaluation.
In this context, the selection of heat exchange components has become extremely critical. Kaori brazed plate heat exchangers provide high efficiency, stability, and reliable performance, ensuring that environmental chambers maintain precise, uniform, and continuous control during cooling, dehumidification, and temperature regulation, making them the most ideal choice for environmental chamber applications.
Environmental Chamber Configuration
A typical constant temperature and humidity test chamber mainly consists of the following systems:
control system, refrigeration/cooling system, heating system, humidity control system, and air circulation system.
- Refrigeration/Cooling System: Uses compressors, condensers, expansion valves, and evaporators for cooling to achieve the required low temperatures. A single-stage system can reach approximately –40 ℃. For lower temperatures (such as –70 ℃ or below), cascade systems are commonly used.
- Humidity Control + Dehumidification: When the air inside the chamber is cooled below the dew point, mechanical dehumidification can be performed, removing moisture in the form of condensation.
Because the temperature and humidity conditions of such test chambers are critical to the reliability of test results, good heat exchange and cooling design are key to whether the equipment can meet specifications and maintain stable operation.
