BPHTC Boiling Point Heat Transfer  Computerized Unit Refrigeration Training Equipment Educational Equipment

This unit is designed to display the various types of boiling at variation of the intensity of the heat flow. More precisely, it allows to reproduce the nucleate and the film boiling and to plot the so-called “pool boiling” which is the basis of the design of the systems with the steam boiler. The experiment is performed with environmental-friendly, special low boiling point liquid.
A transparent vessel allows to observe the evaporation process at the heated cylinder. The cylinder operates as a fire tube heated from inside. An integrated water-cooled condenser allows for a continuous boiling process. The special liquid used evaporates at low temperatures.
A PC data acquisition and analysis system allows to acquire automatically the measurements, to display the curves on the screen and to save the experimental data for further analysis.
