In the field of commercial refrigeration, both glass-door walk-in cooler and traditional cold storage are widely used.

People often assume that these two are basically the same type of refrigeration equipment. However, in fact, they have their own characteristics and different applicable fields.

Under the current trend of increasingly emphasizing market segmentation, it is necessary for us to carefully understand these professional refrigeration equipment.

Based on different market requirements, one’s own conditions, development goals and the local business environment, we choose the most suitable products for ourselves.

 

Now let’s separately discuss the similarities and differences between glass-door walk-in cooler and traditional cold storage.  For readers’ reference.

 

1. The similarities between the two mainly lie in the following aspects

 

① Refrigeration Principle

The refrigeration principles  of both glass door walk-in cooler and traditional cold storage are basically the same.

Both of them employ a steam compression refrigeration cycle (compressor – condenser – expansion valve – evaporator), using the refrigerant to absorb heat in a transformed manner to lower and maintain the temperature inside the storage facility.

 

② Insulation materials for the storage container

The storage container is constructed by assembling polyurethane (PU) sandwich panels, which helps reduce heat loss and maintain a stable low temperature inside the container.

 

③ Basic Functions

Whether it is a glass door walk-in cooler or a traditional cold storage, they are all used for the low-temperature storage of food, medicine, or reagents. Both can be designed as refrigeration (0 – 10℃) or freezing (-18 – -35℃) as per requirements.

 

④ Thermal control system

Both models are equipped with temperature controllers/digital temperature controllers or microcomputer control systems, which can achieve setting of temperature, automatic start-stop of the compressor, defrost control, etc.

 

⑤ The basic requirements for the usage scenarios are the same

They all need to consider ground load-bearing capacity, ventilation and heat dissipation (for the outdoor unit of the machine), power matching (220V / 380V), drainage, and regular defrosting maintenance.

 

2. Main Differences

We visually present their differences through a table.

 

 

By comparing their similarities and differences, we can draw the following conclusion:

From the perspective of fundamental differences，

Glass-door walk-in cooler is more about “display and convenient picking”;

Traditional cold storage is more about “high insulation, large storage capacity, and freezing”.

 

And we have found that glass-door walk-in cooler is more suitable for the following scenarios:

• Supermarket, specialty fresh food store (display and storage of beverages, dairy products, cooked foods, fresh-cut fruits)
• Hotel/restaurant open kitchen, bakery (requiring quick stock retrieval and frequent small-volume access)
• Locations with requirements for store image and product display effect
• Gas station convenience store that mainly uses refrigeration, with high daily opening frequency but short single-time duration.
