COMPUTER CONTROLLED - CROSS FLOW HEAT EXCHANGER (Water to Water Type) (With Data Logging Facility)

Code:
DESCRIPTION:
The apparatus consists of fabricated SS shell, inside which SS tubes are fitted. Hot water passes to one end through the tubes and exit to another end. The cold water is admitted at the one end of shell, which passes over the hot-water tubes. The tubes are arranged in the shell so that the flow of cold and hot fluid crosses each other to make it cross flow. Valves are provided to control the flow rates of hot and cold water. Flow rates of hot and cold water are measured using flow sensors. A magnetic drive pump is used to circulate the hot water from a re-cycled type water tank, which is fitted with heaters and Digital Temperature Controller. Cold water is to be supplied by laboratory overhead tank by end user.

The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Lab view of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by “Lab Smith”. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.

E
XPERIMENTATION:
The main object of the experimental setup is to study the following at various flow rates:
  • LMTD.
  • Heat transfer rate
  • Overall Heat Transfer Co-efficient.
