CPC Definition - Subclass F28C
This place covers:
Heat exchangers involving heat transfer between different media without separating wall, e.g. cooling towers.
This place does not cover:
Mixers | |
Chemical or physical processes | |
Fluid heaters having heat generating means | |
Regenerative heat exchangers | |
Latent heat storage in direct contact with a heat exchange medium or another latent heat storage medium |
This place covers:
Heat exchangers in which one medium trickles freely over a material and is brought into direct contact with a cooling medium. e.g. ambient air.
Cooling towers are classified according to the type of flow: counter-current, cross-current or both.
This group covers also:
- The use of cooling towers for discharging exhaust gases.
- Means for recovering heat from exhaust steam.
- Noise suppressing means.
- Freezing prevention means.
- Combination wet/ dry sections (hybrid cooling towers).
- Means for preventing mist formation above cooling towers.
This place does not cover:
This place covers:
Direct contact heat exchangers without trickling of one heat exchange medium, e.g. direct contact between two gases , between two liquids or between a liquid and a gas without or with change of state; one of the heat exchange medium being a fluent solid, e.g. direct contact fluidized bed.
This place does not cover:
Preservation of food by heating loose materials | |
Evaporating with heated gases or vapours or liquids in contact with a liquid | |
Distillation or related exchange processes in which liquids are contacted with gaseous media, e.g. stripping | |
Mixing gases with liquids | |
Devices using other cold materials | |
Furnaces, ovens with cooling grates, endless belts, rotary drums | |
Direct contact condensers | |
Indirect contact fluidized bed |
