In the composition of high – low temperature test chambers, the refrigeration compressor is undoubtedly a core component, and its selection directly determines the quality of the test results. In fact, semi – hermetic refrigeration compressors are predominantly used in high – low temperature test chambers. What secrets lie behind this choice? Let’s delve into the three key reasons together.

Significant Noise Reduction, Creating a Quiet Test Environment
High – low temperature test chambers have certain requirements for the quietness of the operating environment, and semi – hermetic refrigeration compressors excel in noise reduction. The motor of this type of compressor is ingeniously integrated inside the compressor body. This unique design effectively reduces the noise leakage generated by the motor’s operation from the source. Moreover, it adopts a well – designed exhaust chamber and separator, combined with a double – layer structural design, which further optimizes the propagation paths of airflow and sound. As a result, it effectively lowers the noise level during the equipment’s operation, creating a quieter environment for the tests.

Stable and Reliable Operation, Ensuring the Continuity of Tests
Stable and reliable operation is a crucial requirement for test equipment, and semi – hermetic refrigeration compressors demonstrate remarkable advantages in this regard. Their suction ports are equipped with filter devices, which act as the “guardian angels” of the equipment. These devices can accurately filter out impurities within the system, preventing them from entering the compressor and affecting its normal operation. Through this filtration mechanism, the purity of the gas entering the compressor is ensured, allowing the equipment to run more smoothly and efficiently. This greatly reduces the risk of operational failures caused by impurities, thus guaranteeing the continuity and stability of the tests.

Unique Oil Supply Design, Reducing Faults and Improving Efficiency
The stability of the oil supply system is of vital importance for the normal operation of compressors, and semi – hermetic refrigeration compressors feature a unique and innovative oil supply design. Within the compressor, all lubricated parts adopt a special start – up oil supply method based on high – low pressure difference. This design cleverly utilizes the high – low pressure difference inside the compressor to ensure sufficient oil supply without the need for additional auxiliary equipment such as a drive motor, oil pressure regulating valve, and oil pump. This not only guarantees the reliable operation of the compressor under various working conditions but also significantly reduces equipment problems caused by failures in the oil supply system, lowers the fault rate, and improves the overall operational efficiency of the equipment.

The above are the numerous advantages of choosing semi – hermetic refrigeration compressors for high – low temperature test chambers, which are also important reasons for their widespread adoption. However, it should be noted that there are not only semi – hermetic piston – type compression refrigeration methods for the refrigeration systems of test equipment; there are also various other types of compression refrigeration methods. For manufacturers, when producing equipment for customers, they will fully consider the customers’ needs and carefully configure compressors with excellent performance.

For customers, the quality of the compressor is a key factor that cannot be overlooked when selecting equipment in the early stage. If the equipment uses a low – quality compressor, it is likely to fall short of performance expectations, leading to inaccurate test results or an unsmooth test process. In such cases, customers need to exercise caution and make a new choice. Of course, if customers have a deep understanding of compressors, they can also specify corresponding compressor brands to further enhance the overall efficiency and other performance aspects of the equipment, ensuring that the test equipment can better meet their own needs.
