Boiling Heat Transfer system trainer (TD-007) tends to demonstrate boiling and evaporation processes. It allows students to understand different forms of evaporation (nucleate and film boiling) and calculate heat transfer coefficients.

  • Boiling Heat Transfer Training System is an educational unit for the investigation of evaporation processes.
  • The trainer is designed to illustrate different boiling and evaporation processes and the effect of pressure and temperature on these processes.
  • The trainer consists of a main tank, condenser coil, heater, vacuum pump, valves, different sensors, digital displays and switches
  • The processes take place in a transparent tank which allows the evaporation to be observed.
  • The cooling water of the condenser coil comes from tap water with flexible hose connection to supply and drain.
  • The trainer is supplied with a needle valve to control the flow rate of the condenser water cycle
  • The heater is operated only when the limit switch detects the freon covered the whole surface area of the heater to avoid heater damage
  • The vacuum pump decreases pressure in the tank so freon R141b boils at temperature less than 32 c which helps trainees to test freon boiling at different temperature.
  • The sensors record the flow rate of the cooling water, the inlet/outlet condenser freon temperature, the vapour and liquid temperature at all relevant points and allow analysis of the heat transfer process
  • The digital displays provide an accurate reading of temperatures and pressures that are measured by highly sensitive sensors.
  • The trainer provides calculation of energy balances and key figures for heat transfer.
  • The trainer is provided with two schematic diagrams to demonstrate the system operation.
  • The trainer is provided with software to demonstrate the measured Values and draw experimental curves related to specific experiment.
  • The control unit includes ON/OFF main power switch and emergency switch
  • The control unit provides a mode selection switch Manual/Software and features a power control on the heater
