Refrigerant recovery machines

May 30, 2025

Refrigerant recovery machines, also known as refrigerator or air conditioning compressors, are core components of refrigeration systems, responsible for compressing refrigerants to achieve refrigeration cycles. Below is the key information about the latest X520 refrigerant recovery machine launched by Haosail:


Haosail X520 Refrigerant recovery machines is designed to meet the entry-level needs of automotive repair workshops, focusing on the recovery of R134a refrigerant, the most common type in current vehicle air conditioning systems. This equipment integrates functions of recovery, vacuuming, and recharging, excelling in operational simplicity and precision. Sharing the same basic features as other models, it is an ideal solution for repair workshops to control costs while providing perfect services to customers. The device is equipped with an electronic scale with a precision of +10g to ensure the accuracy of charging.


The working principle of the refrigerant recovery machine is based on the physical state changes of the refrigerant, achieving cooling effects through heat absorption and release during compression and expansion processes. The specific process is as follows:

1. **Compression process**: The compressor compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure state.


2. **Condensation process**: The high-pressure gaseous refrigerant releases heat in the condenser and transforms into a high-pressure liquid.


3. **Expansion process**: The liquid refrigerant flows through the expansion valve (throttling device), reduces pressure, and enters the evaporator.


4. **Evaporation process**: The low-pressure refrigerant absorbs heat from the surrounding environment in the evaporator and vaporizes, thereby achieving the refrigeration effect.


### Application Fields Refrigerant recovery machines are widely used in air conditioning, refrigeration equipment, industrial cooling systems, and other fields. With technological advancements and higher environmental requirements, new refrigerants such as R410a, R32, and R134a have gradually replaced environmentally harmful refrigerants like R22. Haosail's equipment uses R134a refrigerant.


###Refrigerant recovery machines Maintenance Key Points


1. Regularly inspect the operating status of the compressor, including oil level, oil quality, and operating noise.


2. Keep the condenser and evaporator clean to ensure heat exchange efficiency.


3. Regularly replace filters and refrigerants to prevent system blockages and performance degradation of the refrigerant.


4. Check electrical connections and control systems to ensure normal operation.


Proper maintenance Refrigerant recovery machines is crucial to ensuring the efficient operation of the refrigerant recovery machine and extending its service life. Meanwhile, with the enhancement of environmental awareness, the design and application of refrigerant recovery machines continue to develop toward a more environmentally friendly and energy-efficient direction.
