Shell & tube evaporators are important components widely used in industrial refrigeration and heat transfer systems.

What is a Shell & Tube Evaporator?

Shell & tube evaporators are a device designed to provide heat transfer of two different liquids (usually a refrigerant and a process fluid). These systems consist of an outer shell and tubes inside. The inner tubes are where the coolant circulates, while the outer shell is where the process fluid passes through.

Working Principle

The working principle of shell & tube evaporators can be summarized in the following steps:

1. Coolant Inlet:

   • The refrigerant enters the inner tubes, during which it evaporates under low pressure. This phase allows the liquid to take the heat and turn into vapor.

2. Inlet of Process Fluid:

   • In the outer shell, process fluid (e.g. water) circulates. This fluid takes heat from the coolant in the inner tubes.

3. Heat Transfer:

   • As the coolant evaporates, heat is transferred to the process liquid passing through the inner tubes. This increases the temperature of the process liquid.

4. Evaporation

   • The refrigerant liquid evaporates completely and exits in the form of vapor. This vapor is usually directed to the compressor, allowing the refrigeration cycle to continue.

This cycle is repeated continuously, ensuring that the system provides efficient cooling.

Advantages of Shell & Tube Evaporators

Shell & tube evaporators have many advantages:

• High Heat Transfer Efficiency:

  • Thanks to its design, heat transfer is highly efficient. This reduces energy costs and improves system performance.

• Resilience

  • They are made of durable materials, which ensures a long service life. They are resistant to extreme pressures and temperatures.

• Easy Maintenance:

  • The internal piping of evaporators can be easily cleaned when required. This simplifies regular maintenance and repair processes.

• Flexibility:

  • They can be manufactured in different sizes and capacities, making them suitable for a variety of applications.
