Cold Rooms: Revolutionizing Controlled Temperature Storage Solutions

Knowledge Center Thumbnails

A cold room is a constructed space for storage of material and goods that is maintained at a low temperature, usually between freezing (-18°C or 0°F) and refrigeration (around 4°C or 38°F). Food, pharmaceuticals, and other perishable goods which are sensitive to temperature are stored in these rooms.

Industries, which include food delivery and storage, supermarkets, restaurants, pharmaceutical firms, and research labs, frequently use cold rooms. They have refrigeration systems installed, which help in maintaining the proper low temperatures and humidity levels to guarantee that the products being stored are safe and of high quality.

How do Cold Rooms Work?

Cooling the cold room is mostly the responsibility of the refrigeration system. It includes multiple essential components:

  1. Compressor: Compressing a refrigerant gas (such ammonia or Freon) to raise its temperature and pressure is the first step in the process.
  2. Condenser: The condenser coils receive the high-pressure, high-temperature refrigerant gas. Here, the gas condenses into a high-pressure liquid by releasing heat into the surrounding environment, which could be either air or water.
  3. Expansion Valve: After that, an expansion valve or throttling mechanism is passed through by the high-pressure liquid refrigerant. This valve abruptly lowers the pressure, which causes the refrigerant to expand and cause a reduction in temperature.
  4. Evaporator: Within the cold chamber, the refrigerant expands and cools before entering the evaporator coils. The refrigerant cools the air inside the room by absorbing heat from the air as it evaporatively turns into a gas.
  5. Cycle Continuation: To resume the cycle, the refrigerant gas goes back to the compressor. The cold room’s interior is kept cold by this ongoing cycle of compression, condensation, expansion, and evaporation.

Components of Cold Room Systems:

Walls, Floors, and Ceiling: These mentioned items are built from insulated panels consisting of mineral wool, polystyrene, or polyurethane foam and sandwiched between metal panels. These panels are commonly refereed to as Insulated Metal Panels (IMP). The cold room’s insulation reduces heat transfer between the interior and exterior of the cold room.

Refrigeration System: The refrigeration system is responsible for cooling the cold room. The evaporator, expansion valve, condenser, and compressions are parts of the refrigeration system.

Thermostat or Temperature Controller: The required temperature range for the cold room can be set and managed by users with this device.

Temperature Sensors: The cold room’s temperature is tracked using temperature sensors. They give the control system feedback so that the predetermined temperature values are maintained within the space.

Fans & Blowers: To provide adequate air circulation, cold rooms are furnished with fans or blowers. They help in ensuring consistent cooling and reducing temperature fluctuations by distributing the chilled air throughout the storage area in a uniform way.

Humidity Control: To regulate the humidity levels, cold rooms are equipped with humidification or dehumidification systems. This is essential as certain products need to be maintained at a certain relative humidity.

Cold Room Door: To stop cold air loss and maintain temperature stability, the cold room door is well-insulated and equipped with seals.


Cold rooms are important equipment that offer accurate temperature control and storage options for a variety of businesses. Because of their ability to maintain product safety, maintain freshness, and adhere to legal requirements, they are crucial parts of contemporary supply chains and operations. The preservation of product integrity and the extension of shelf life are critical functions of cold rooms which are crucial to overall efficiency, quality control, and customer satisfaction even as industries change.
