What is Cold Room

A cold room is a storage room that generally designed for storing products in which a temperature can control by people. Since the end of the 19th century, cold storage room has been an important part of the industries. Cold rooms are used to store anything that needs to be refrigeration to avoid it becoming perished. Many products that need refrigeration system for example fruits, vegetables, seafood, meat, flowers and others. The temperature of the cool room is depending on the product that will be stored. For foods storage for their preservation, such as frozen foods, which are stored at below zero temperatures. Some vegetables and fruits are also stored at 0 °C.

Why want to apply cold room?

Cold storage is a typical room with low temperature, it can maintain temperature with refrigeration and air conditioning techniques. The refrigeration systems are critical to extending product life and help maintain product quality. It also helps to reduce the wastage of commodities. The most common places to used a cold room is the food industries. Business premises here tend to use them to store large amounts of food. This enables them to purchase the things that they need in mass and to be able to store them without worrying about the foods becoming perished.

How does cold room work?

All the cold room refrigeration systems have 5 main components:

  1. Compressor
  2. Condenser
  3. Expansion Valve
  4. Evaporator coils
  5. Fan or fans

First of the component is the compressor. The compressor is which compresses the refrigerant gas. Second is the condenser which let the hot gas is cooled to a liquid. An expansion valve is to controls flow of the liquefied gas and where liquid gas expands to vapor. After that, evaporator coils are where the liquid gas expands and boils. This process absorbs energy, cooling the coils. Lastly are fans. Fans are to circulate air over the cold evaporator coils, thereby cooling the cool room. Air may also be circulated over pipes containing some type of liquid antifreeze, which have themselves been cooled using the evaporator. Fans also circulate air around the cool room to ensure even distribution of the cold air and reduce temperature variations within the room.

Where can apply these cold room?

Many industries require precise temperature control environments or cold storage to store their goods or as part of their manufacturing process. The following industries, especially refrigerators and equipment, have the highest utilization rates:

  1. Grocery stores.
  2. Restaurants and kitchens.
  3. Hospitals, clinics and medicine.
  4. Science laboratories and research centers.
  5. Food processing or food manufacturing.
  6. Information Technology and data centers.

Conclusion

A cold room is a warehouse in which a specific temperature is artificially generated. It is generally designed for storing products in an environment below the outside temperature. The refrigeration systems are critical to extending product life and help maintain product quality. There are 5 main components in the cold room system: compressor, condenser, expansion valve, evaporator coils and fans. Many industries require precise temperature control environments or cold storage to store their goods or as part of their manufacturing process.
