Process Design of Heat Exchanger: Types of Heat exchanger ...
www.nptel.ac.inTransfer of heat from one fluid to another is an important operation for most of the chemical industries. The most common application of heat transfer is in designing of heat transfer equipment for exchanging heat from one fluid to another fluid. Such devices for efficient transfer of heat are generally called Heat Exchanger.
CHAPTER 6 HEAT TRANSFER APPLICATIONS - NZIFST

Heat Stress: First Aid for Heat Illness
www.cdc.gov• Feeling ill while working in the heat is a serious warning sign. Any employee who reports feeling unwell during work in hot conditions could have heat exhaustion, which can quickly progress to heat stroke if not treated. • Proper first aid for someone with suspected heat exhaustion or heat stroke involves COOLING the
Heat Exchangers - Jordan University of Science and Technology
www.just.edu.joHeat Exchangers Heat exchangers are used to transfer heat between two sources. The exchange can take place between a process stream and a utility stream (cold water, pressurized steam, etc), a process stream and a power source (electric heat), or between two process streams resulting in energy integration and reduction of external heat sources. ...
