Currently, industrial refrigeration systems are fundamental for global manufacturing processes, requiring high-quality and high-performance equipment, as well as a proper selection of materials and components in industrial refrigeration to ensure optimal results.
At Inditer, we specialize in industrial, commercial, domestic, and automotive refrigeration equipment and systems. We have over 18 years of experience in the sector and can offer you the best thermal exchanger solutions, as well as comprehensive advice on industrial refrigeration components.
It is worth mentioning that industrial refrigeration is applied in various sectors such as food, chemicals, construction, textiles, plastics, among many others. That said, in this post, we will focus on outlining the essential materials and components in industrial refrigeration and the importance of selecting them correctly.
Components of Industrial Refrigeration Systems
Below, we present the essential materials and components in industrial refrigeration systems:
1) Compressor
It is one of the fundamental components in industrial refrigeration, responsible for compressing the refrigerant gas and circulating it throughout the entire refrigeration system.
Due to heat, the refrigerant evaporates and enters the compressor, a device that increases its temperature and pressure. It is important to note that for this process to be carried out effectively, the temperature must be higher than that of the condensing fluid.
Compressors function similarly to a pump, as they facilitate the movement of fluid to circulate within the refrigeration system.
There are various types of industrial compressors:
- Piston
- Centrifugal
- Rotary
- Screw
2) Evaporator
Another essential component in industrial refrigeration is the evaporator, which is a coil that acts in the final phase of the cycle and functions to absorb heat from the environment, as well as to evaporate the liquid refrigerant, transforming it into gas.
By transforming the refrigerant into a gaseous state, it can exit the evaporator as vapor and thus re-enter the compressor.
Depending on the needs of the industrial refrigeration system, Inditer offers a wide range of evaporators to cover any required need in a refrigeration installation, such as:
Cubic Evaporators
These cubic or rectangular evaporators are commonly used in industrial refrigeration systems. They are designed to provide uniform cold air distribution within a refrigeration chamber or space. Their compact and efficient design allows for effective heat exchange and rapid cooling.
Ceiling Evaporators
Ceiling evaporators are installed on the ceiling or at the top of the refrigeration chamber. They are designed to maximize usable space within the chamber, as they do not occupy floor space. These evaporators blow cold air downwards, creating a downward current that provides uniform temperature distribution throughout the chamber.
Inclined Evaporators
Inclined evaporators are designed with an inclination in their heat exchange surface. This inclination allows condensation to drain more easily, preventing the accumulation of moisture and ice on the evaporator surface. By reducing ice formation, these evaporators improve heat exchange efficiency and minimize the need for frequent defrosting.
Wall-mounted Evaporators for Freezing Tunnels
These evaporators are used in freezing tunnels or ultra-freezing chambers. They are installed on the walls of the tunnels and are designed to provide rapid and uniform refrigeration in low-temperature environments. These evaporators are built to withstand extremely low temperatures and maintain high efficiency even in freezing conditions.
Manufacture of Special Solutions
This term refers to the creation of customized evaporators for specific industrial applications. In some cases, industrial refrigeration systems require tailored solutions to adapt to the particular needs of an industry or process. The manufacture of special solutions involves the design and construction of custom evaporators that meet the specific requirements of the application in question.
3) Condenser
The condenser is one of the essential components in industrial refrigeration, responsible for cooling the refrigerant gas and transforming it into liquid.
The refrigerant gas enters the coil or condenser after leaving the compressor, and because this device is exposed to cold, heat is released, which can occur in an environment of water, outdoor air, or other fluids.
In this process, the fluid condenses and turns into a liquid state. The purpose of this process is for the refrigerant to reach a lower temperature and exit the device colder while maintaining the same pressure.
The condensers used in industrial refrigeration systems are:
- Water-cooled condensers: transfer heat to water to extract it and move it away from the refrigerant, using a second tube with water that surrounds the pipe through which the refrigerant circulates.
- Air-cooled condensers: expose the refrigerant to outside air to reduce its temperature, often with fans. Inditer offers a catalog of condensers for commercial and industrial applications.
- Evaporative condensers: widely used in industry. They work by spraying water to promote air cooling and improve condenser efficiency. Inditer offers a range of adiabatic equipment.
4) Expansion Valve
It is a device that controls the flow of liquid refrigerant to the evaporator and helps maintain a constant temperature, thus representing another essential component in industrial refrigeration.
Upon exiting the condenser, the liquid refrigerant enters the expansion valve, performing functions such as:
- Reducing pressure.
- Decreasing the refrigerant flow rate to the evaporator.
This valve is located between the low and high-pressure zones of the cycle, so that the refrigerant reaches an ideal temperature for refrigeration.
5) Refrigerant
The liquid or gas refrigerant is another essential material and component in industrial refrigeration, used for extracting heat from the environment, transporting it from one area of the system to another.
Refrigerants can be special substances or gases that allow the cycle to be refrigerated; in fact, it can even be water.
Currently, although refrigerants that include hydrocarbons, carbon dioxide, and fluorocarbons among their components are still used, there is an evolution towards the use of natural refrigerants, for which Inditer has a catalog of solutions for:
- CO2
- Ammonia
- Water and Glycol Mixtures
It should be noted that there are also other refrigerant liquids that include hydrocarbons, carbon dioxide, and fluorocarbons among their components.
6) Pipes and Connections
Pipes and connections are used to link the rest of the components of a refrigeration system.
For evaporators, Inditer uses pipes with specially reinforced thicknesses to withstand the high pressures of CO2. Regarding the GasCooler, Inditer uses a special copper alloy, K65, which ensures operating pressures of up to 120 bar of CO2.
7) Lubricating Oil
Another indispensable material for an industrial refrigeration system is oil, which aims to lubricate the system’s moving components, such as the compressor, to prevent friction and wear.
8) Controllers and Sensors
These devices are responsible for controlling and monitoring the system’s operation. They adjust the refrigerant flow, pressure, and temperature.
9) Insulation
Insulation is used to prevent ambient heat from penetrating the industrial refrigeration system and helps maintain a constant internal temperature.
Importance of Proper Component Selection
It is important to highlight that all materials and components are essential in industrial refrigeration to ensure optimal operation of these types of systems, as the absence of any of them would prevent achieving optimal levels of system efficiency.
It is advisable to seek advice from specialists in the sector to achieve the most suitable results for each type of industry.
