Automated Advance Heat Transfer Rig

Automated Advance Heat Transfer Rig

Teaching Objectives of

• Implementation of a heat exchange.
• Analysis of heat exchange performances.

Possible Experiments:

• Determination of :
• Heat balances.
• Global heat transfer coefficients
• Flow regimes
• Study of the effect of transfer mode (con or counter-current).
• Study of the effect of hot and cold fluid supply.
• Comparison of the efficiency of 4 types of heat exchangers.

Technical specifications

• 1 coiled exchanger
• 1 concentric exchanger
• 1 plate exchanger with brazed plates
• 1 Shell & tube exchanger
• 21 stainless steel manual valves
• 5 pressure gauges
• 1 electronic flowmeter (cold circuit)
• 1 electronic flowmeter (hot circuit)
• 1 stainless steel pneumatic valve for the cold water flow
• 1 stainless steel pneumatic valve for the hot water flow
• 2 converters P/I
• 1 electrical cabinet
• 16 temperature probes
• 2 temperature displays with a 2 positions switch and a 4 positions switch and a communications card type RS485
• 4 temperature displays with RS485 output and one RS485/RS232 converter
• 2 flowmeters displays
• The exchangers are out of stainless steel
• The external grills of the exchanger with serpentine and the multitubular exchanger are out of glass.
• The external grill of the monotubular exchanger is out of stainless steel.
• The circuit is carried out in stainless steel piping and is assembled on welded stainless steel frame.
• A technical manual is delivered with the bench.
• A supervision software designed on Labview allowing to configure remotely the regulators, to select the temperature displays and to control the flow according to the selected exchangers and the transfer mode.
