Difference Between Heat Exchangers and Interchanger
Exchanger Heat
Heat Interchanger
Differences in Application and Function
Aspect | Heat Exchanger | Interchanger |
Purpose | Transfers heat between two fluids | Enhances performance in refrigeration systems |
Mechanism | Direct fluid heat transfer | Uses refrigeration units for cooling |
Common Uses | Industrial processes, power plants, chemical processing | Refrigeration systems, particularly in commercial settings |
Core Components | Often involves specialized boiler tubes, such as ASTM A106 and ASME SA106 pipes | Includes ASTM A106 and ASME SA106 pipes for efficient heat exchange |
Effects on System | Increases efficiency by recovering heat | Improves system performance by regulating suction gas temperature and liquid subcooling |
Sizing Considerations | Must be appropriately sized to avoid pressure drop or overheating | Must balance size to ensure effective heat exchange without negative impact on system |
Conventional Application
Increasing the Suction Gas Temperature
Classification of Heat Exchangers
- Direct Transfer Type: Hot and cold fluids are separated by a metal wall through which heat transfers. Example: shell and tube heater.
- Storage Type: A hot fluid heats a porous solid, then a cold fluid extracts heat from the solid. This type is not common in the pharmaceutical industry.
- Direct Contact: Hot and cold fluids are not physically separated. Example: steam bubbles through a cold liquid.
