Upgrade of the single-stage compressor system of ASLI constant temperature and humidity test box
In traditional constant temperature and humidity test boxes, the single-compressor refrigeration method has been widely used by many manufacturers to achieve cooling effects. While this system offers good mass performance, the refrigerant inside is often pushed to its limits, with cooling control reaching as low as -43°C, which falls short of the required -40°C standard. This raises an important question: why do so many manufacturers still rely on a single compressor for their refrigeration tests? Can the refrigerant actually deliver optimal experimental results?
As the product continues to evolve, Ai Si has invested in long-term improvements and upgrades to meet the specific temperature requirements of compressors. The imported Taikang totally enclosed compressor used in our test chambers not only allows the refrigerant to reach -40°C but also enhances the accuracy and efficiency of the cooling process.
When using a single compressor for testing at -40°C, the refrigeration system operates under high load continuously. This can pose risks to both operators and the surrounding environment. During this process, fluctuations in ambient temperature may trigger alarm signals, or the equipment might suffer damage due to prolonged high-speed operation. These issues highlight the limitations of the single-compressor system—its refrigerant cannot consistently meet the ideal conditions required for optimal experiments.
Manufacturers often choose this type of compressor due to its reliable quality and relatively low operational costs. However, the system's lifespan is limited, typically lasting around 100 hours above 40°C. Moreover, the need to replace the compressor every two years has led to its gradual decline in popularity, as it becomes less attractive compared to more advanced alternatives.
