Under What Conditions Are Dual-Cascade Refrigeration Systems Used in Temperature and Humidity Test Chambers?

A dual-cascade refrigeration system refers to a setup where two refrigeration units work in tandem to provide enhanced cooling capacity. This ensures continued operation and improved stability of the test environment even if one unit fails. In temperature and humidity test chambers, dual-cascade refrigeration is typically employed for tests requiring higher precision or larger testing spaces.

When the internal environment of a temperature and humidity test chamber must maintain extreme accuracy, a dual-cascade refrigeration system enhances stability and test precision. In large testing chambers, a single refrigeration unit may struggle to meet cooling demands, whereas a dual-cascade system delivers greater cooling capacity. Additionally, this setup prevents environmental fluctuations in case of refrigeration unit failure, ensuring test stability.

Dual-cascade refrigeration is an effective solution for temperature and humidity test chambers requiring higher precision or larger testing spaces.
