The constant temperature and humidity test chambers manufactured by Dongguan Haotian Testing Equipment Co., Ltd. are equipped with high-quality compressors from three leading brands: Comtek, German Copeland, and German BITZER. These compressors play a crucial role in maintaining the stability of the testing environment.

How Does the Compressor Work?

The compressor is the core component of the refrigeration system. It functions as a driven fluid machine that takes low-pressure gas and compresses it into high-pressure gas. This process powers the refrigeration cycle, which consists of four main stages: compression → condensation → expansion → evaporation (endothermic). The compressor draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a motor-driven piston, and then discharges the high-temperature, high-pressure gas through the exhaust pipe to continue the cooling process.

What to Do When a Leak Is Detected?

If a leak occurs in the refrigeration system, you can use a combination of a leak detector and soapy water to identify the source. For example, if the hot gas bypass solenoid valve's stem is cracked or has a slit, it needs to be replaced immediately. If a leak is found elsewhere, such as at a connection point or valve, you should repair it using oxygen welding. After fixing the issue, the system should be refilled with refrigerant to restore normal operation.

Dongguan Haotian Testing Equipment Co., Ltd. offers a wide range of environmental testing equipment, including walk-in constant temperature and humidity chambers, thermal shock test chambers, programmable constant temperature and humidity chambers, high and low temperature test chambers, damp heat aging chambers, high temperature aging chambers, sand and dust test boxes, rain test chambers, UV aging test chambers, waterproof test rooms, and large-scale environmental reliability testing systems. These products are widely used in industries requiring rigorous quality control and environmental simulation tests.
