The use of cold rooms is very wide at an industrial level. A cold room of this type is a refrigerated enclosure using a vapor compression system maintained at low temperatures. To guarantee this sufficiently low temperature, walls and enclosures with very good insulating properties are used.

Applications In The Industry

Cold rooms are widely used in all types of sectors, highlighting, for example:

• Food Industry

They allow food to be maintained and preserved in adequate conditions. They are used in the field of the dairy and agricultural or fishing industry, among others.

• Pharmaceutical Sector

Most of the compounds used in the field of pharmaceutical or biotechnological industry require low storage temperatures.

 Components Of Industrial Cold Rooms

Industrial cold rooms are made up of two basic components: firstly, what constitutes the cold room itself (enclosure) and, secondly, the cold production equipment. Furthermore, there are other additional systems such as lighting and control, for example.

The Cold Room: Materials And Characteristics

The chamber is made up of enclosures, built to measure or use prefabricated materials, which are characterized by having very low conductivity, preventing the transmission of heat to the interior. The proper thickness of insulation depends on factors such as the difference in outside and inside temperatures, or the maximum allowable heat flux. The use of prefabricated panel systems for cold rooms is becoming more and more common due to their ease of use and installation and because they comply with the best quality standards and have elements that improve performance and energy efficiency. This includes adequate vapor barriers. These barriers prevent the appearance of condensation on the insulation.

Cold Production And Distribution System

The chambers use cold production systems based on vapor refrigeration cycles, similar to those used in refrigerators or other cooling devices. The generated cold can be distributed using air or other fluids such as cold water.

Energy Efficiency In Cold Rooms

Cold rooms are one of the points with the highest energy consumption within industries and it is essential to have a design and maintenance that guarantees the best possible energy efficiency. For this, it is essential to follow some basic design and maintenance criteria, which must include all the components of the chamber and also the regulation and control systems.

Adequate And Highly Efficient Cold Production Machines

The size and power of cold production machines must follow the real needs of the chamber and it is also important that the compression ratio (ratio between the condensation and evaporation pressures) be as low as possible. High-efficiency, variable-speed fans should be used, and high-efficiency coolant systems should be chosen. In addition, an adequate preventive maintenance protocol is essential.

Final Words

A careful design of the cold room as a whole, as well as having adequate maintenance operations, is the best guarantee to reduce the energy consumption of the installation, increase its useful life and also guarantee the best temperature and humidity conditions inside.
