Difference Between External and Internal Units of Chiller

 

In the world of commercial refrigeration, certain chiller freezers come with either an internal or an external refrigeration system. Understanding the differences between these two types is crucial when selecting the right commercial refrigerator for your business. Below, we will explore the differences between chiller fridge with external and internal units, and how each option can benefit your operations.

 

External Units: Split-System Chiller Freezers

 

Freezers with external units, commonly referred to as split-system chiller freezers, work similarly to household air conditioning systems. In a split-system, the main unit (internal) is responsible for maintaining a low temperature inside the display chiller, while the external unit disperses heat outside. This design ensures better temperature control and efficiency in large spaces like supermarkets, convenience stores, and F&B outlets.

 

Advantages of External Units:

 

  1. Low Noise Levels: One of the significant benefits of external unit freezers is the reduced noise. Since the compressor and fan are located outside, the noise inside the store or kitchen is minimized, comparable to the gentle hum of a small household fan. This quiet operation is ideal for environments where customer comfort or a peaceful ambiance is crucial.
  2. Improved Performance in Large Spaces: External units are highly effective for larger refrigeration systems and can handle heavy cooling demands, making them suitable for commercial applications that require stable, low temperatures for large volumes of goods.

 

Disadvantages of External Units:

 

  1. Installation Complexity: Setting up a split-system chiller fridge requires professional assistance. Since the external unit must be installed outdoors and connected to the indoor freezer, the process can be time-consuming and costly.
  2. Limited Mobility: Once installed, moving a freezer with an external unit is difficult. This limits flexibility if you need to reconfigure your store layout.

 

Internal Units: Self-Contained Chiller Freezer

 

Freezers with internal units, also known as self-contained chiller freezers, integrate both the refrigeration system and compressor within the same unit. This design is akin to household refrigerators, where all the cooling components are housed inside the appliance itself.

 

Advantages of Internal Units:

 

  1. Easy to Move: Unlike external units, chiller fridges with internal systems are more portable and can be easily repositioned. This flexibility is ideal for smaller establishments that may frequently change their setup.
  2. Simple Installation: No need for a professional installation—simply plug the commercial refrigerator into a power source, and it’s ready to go. This convenience makes internal unit chiller freezers popular among businesses that value simplicity and ease of use.
  3. Lower Costs: Internal unit freezers generally have lower upfront costs compared to split-system chiller freezers. They are an excellent option for small businesses or those looking for cost-effective solutions.

 

Disadvantages of Internal Units:

 

  1. Higher Noise Levels: Since the compressor is located inside the display freezer, these models tend to produce more noise compared to their external counterparts. However, the noise is typically within acceptable levels and should not significantly disrupt the environment.
  2. Limited Cooling Capacity: Internal unit chiller freezers may not be as efficient as split systems when it comes to large storage needs. They are more suitable for smaller spaces and light-duty refrigeration.

 

Conclusion

 

Choosing between a commercial freezer with an external or internal unit depends on your business’s specific needs. External unit freezers are ideal for large commercial operations that require quiet, efficient cooling but need professional installation. On the other hand, internal unit chiller freezers offer flexibility, affordability, and ease of use, making them perfect for smaller businesses or those requiring mobile solutions.
