High-performance units, parts revealed: revealing how key components achieve excellent cooling efficiency
5. Refrigerant: The “blood” of the system
Refrigerant is the medium that transfers heat in the refrigeration system, absorbing and releasing heat through phase change (conversion between liquid and gas).
Common refrigerant types:
– R-134a: Widely used in automotive and commercial refrigeration systems.
– R-404A: Suitable for low-temperature refrigeration equipment.
– R-410A: Environmentally friendly refrigerant with high energy efficiency.
– Ammonia (R-717): Used in large industrial refrigeration systems.
Environmental trends:
With increasingly stringent environmental regulations, more and more companies are choosing environmentally friendly refrigerants with low GWP (global warming potential) to reduce the impact on the environment.

6. Fans and blowers: Ensure air circulation
Fans and blowers are key components to ensure air circulation in condensers and evaporators, which directly affect heat dissipation and cooling effects.
Function:
– Promote air flow and enhance heat exchange efficiency.
– Prevent overheating or frosting of condensers and evaporators.
Features of high-performance fans:
– High-efficiency motors: Use energy-saving motors to reduce energy consumption.
– Low-noise design: Optimize blade shape to reduce operating noise.
– Strong durability: Adapt to harsh environments such as high humidity and high temperature.
Maintenance recommendations:
– Clean fan blades regularly to prevent dust accumulation.
– Check the motor operating status and replace worn parts in time.

7. Control system: the “brain” of the unit
Modern high-performance units are usually equipped with intelligent control systems to monitor and adjust the operating status of the unit to ensure efficient and stable cooling effects.
Function:
– Real-time monitoring of parameters such as temperature, pressure and energy consumption.
– Automatically adjust the operating status of components such as compressors and fans.
Features of high-performance control systems:
– Intelligent operation: Support remote monitoring and fault diagnosis.
– Energy saving mode: Automatically adjust operating parameters according to load demand to save energy.
– User-friendly: Equipped with touch screen or mobile phone APP, easy to operate.
Maintenance suggestions:
– Update system software regularly to ensure perfect functions.
– Check sensors and lines to prevent false alarms or failures.

8. Filters and dryers: protect system cleanliness
Filters and dryers are used to remove impurities and moisture from refrigerants to prevent system blockage or corrosion.
Function:
– Filter particulate matter and impurities in refrigerant.
– Absorb moisture in refrigerant to prevent ice blockage.
Features of high-performance filters:
– High-efficiency filtration: Use multi-layer filter screen to capture tiny particles.
– Long-lasting drying: Use highly absorbent materials to extend service life.
Maintenance suggestions:
– Replace filters and desiccants regularly.
– Check system pressure to prevent blockage.
