Walk in coolers can accurately control the indoor temperature and provide a suitable storage temperature for perishable products. They are widely used in restaurants, medical institutions and other industries. But do you know how to build a walk in coolers? In this guide, you will be introduced to the working principles, components and advantages of this large refrigeration system. Help you better build and use walk in cooler.
Important Components Of Walk In Coolers
Refrigeration System
The refrigeration system is the core of the walk in coolers. It consists of three components
- Evaporator coil: made of material with good thermal conductivity, absorbs heat inside the cooler and reduces the temperature
- Condenser: discharges the heat absorbed by the evaporator to the outside
- Compressor: compressor for walk in cooler makes the refrigerant refrigerate from liquid to gas and then from gas to liquid
The three components maintain the operation of the refrigeration system to ensure the continuous operation of the cold room.
Insulation Board
If the refrigeration system is the key to cool the walk in coolers, then the insulation board is the key factor to maintain the temperature of the cold room. The insulation board of the walk in coolers is usually made from high-quality materials like polyurethane or polystyrene. It makes the cold room unaffected by the external temperature, prevents the loss of cold air, and ensures long-term cooling.
Temperature Control System
The commercial walk in cooler is equipped with sensors and thermostats to adjust the temperature to ensure the convenience and efficiency of refrigeration.
Walk In Cooler Door
Walk in cooler door come in a variety of styles, usually manual or sliding. An excellent cold room door can not only save space but also have a good sealing effect to prevent the overflow of cold air.
Ventilation System
The ventilation system is an essential component of the walk in coolers. If you don’t want the air in the cold room to have a serious odor, you must install a good ventilation system.
Working Principle Of Walk-In Coolers
Heat Transfer Mechanism
The working principle of modern walk-in cooler is that the refrigeration system generates cold air, which accumulates in the cooler composed of insulation panels, lowers the temperature in the cooler, and maintains the required temperature inside the cooler through the sensor system and control system.

How To Build A Walk In Cooler？
Planning Before Construction
1 Determine the needs
2 Planning Site Selection
Build indoor or outdoor
Indoor walk in cooler: It can save energy and is easy to use. The service life of the cold storage room is also longer, but ventilation space and maintenance space need to be reserved after the construction of the walk in cooler.
3.Power Supply
It is recommended to install an independent circuit in the cold storage and prepare a backup generator.
Tips For Using A Walk In Coolers
- When using the walk in cooler for the first time or when it has not been used for a long time, the walk in coolers should be cooled to the required temperature before putting the items in, rather than putting the goods in the cold room before starting to cool down
- During use, hard objects should be prevented from colliding with the insulation board of the cooler to avoid damage and depression of the insulation board, which will affect the insulation effect of the cold room.
- Check the sealing degree of the cold room regularly, and repair it in time if it is damaged
- Keep the floor clean when using the walk in coolers. If there is ice or water accumulation on the ground, it should be cleaned in time. It is necessary to pay attention not to use hard tools to avoid scratching the ground and affecting the service life.
- The walk in coolers cannot completely guarantee the consistency of the storage time of the goods. The goods inside need to be checked regularly. Once mold, rot and other problems occur, they should be dealt with in time.
- The temperature and humidity in the cold room should be consistent to avoid large fluctuations.
- When storing goods, try to complete it at one time, minimize the number of times entering and leaving the cold room, and avoid the cold room being affected by the outside temperature. Pay attention to whether the air curtain is open when opening the door.
- It is strictly forbidden to store flammable and explosive items, and open flames are strictly prohibited.
