The MP104M bench allows the study and comparison of four types of exchangers
Thermal exchanges are studied co or against the current.
Experimental possibilities :
- Determination of thermal balances
- Determination of global exchange coefficients
- Determination of the flow regimes
- Influence of the transfer mode (co-current / countercurrent)
- Influence of hot fluid and cold fluid supply
- Comparison of the different types of exchanger.
- Analysis of the performances of heat exchanges.
Option 1 (Data Acquisition): Two electromagnetic demagnetors replace the fuseholders.
The acquisition and the visualization of the temperatures and flows on makes a touch screen of 7 '', moreover these data can be transferred towards a computer (not provided) .The developed software makes it possible to display the temperatures according to the exchanger and the selected traffic mode. This software allows the acquisition and the recording of the measured values, the calculations and the plots of the heat exchange curves as a function of the time for each exchanger.
The following curves can be plotted:
Variation in the amount of heat exchanged as a function of flow
Variation in thermal efficiency E as a function of flow
Variation of heat exchange coefficient U as a function of flow
A synoptic of the installation is displayed on the screen, as well as the details of each exchanger.
An ergonomic menu allows to select the display of the different temperature and flow parameters according to the exchanger to be studied
Option 2 (supervision): This option allows the flow control of hot and cold circuits from a computer. Two flow rates are controlled by a stainless steel pneumatic valve, supplied with 2 P / I converters, the two converters are mounted in the control cabinet, and are configurable according to the computer.
Option 3 (water heating group): electric heating of 9 KW, with pump and tank, maximum temperature of 95 ° C.
