The heat exchangers visualization trainer is designed to investigate the operation of five different types of heat exchangers, in addition to their application. The trainer is completely safe for trainees to perform a wide range of experiments by just controlling the temperatures and flow directions. The trainer is provided with an interactive software to control the processes and take accurate measurements.

                                     
  • The educational unit consists of a large robust frame that includes all components of the heat exchangers cycles.
  • The trainer includes five types of heat exchangers, tubular heat exchanger, shell and tube heat exchanger, plate heat exchanger, stirrer tank heat exchanger and air duct.
  • The air duct heat exchanger is provided with a blower, cooling coil, temperature sensor and flow sensor.
  • The educational unit is also provided with a hot water tank as a hot water supply, a cold-water supply from tap water or external chiller, a process tank and process tank filling.
  • The process tank simulates a swimming pool in order to cool or heat its water using the hot water tank or cold-water source through the heat exchangers
  • Also, the air duct heat exchanger can be used alone with the cold or hot water sources for more applications.
  • The trainer is supplied with three pumps. One to pump hot water from hot water tank, another one to pump water to the process tank and the other one to pump water from process tank to the heat exchangers.
  • The trainer includes an integrated control panel to control the experiments, in addition to a wide range of control valves and switches.
  • The control panel includes main control section, system temperature section, process tank control section, air duct control section, system water flow section, heater section, stirring tank section and process tank switches
  • The main control section contains Hot/ Cold switch, Parallel/ Counter switch, Manual/Software switch and Heat exchanger/Process tank switch.
  • The system temperature section contains digital displays of temperatures of the inlet and outlet of the cold-water and/or hot water sources and temperatures of the inlet and outlet of the process tank.
  • The process tank control section contains Process tank low water LED, Process tank filling pump ON/ OFF switch, process tank drain ON /OFF switch, Filling tank low water LED, Process pump ON/ OFF switch, Digital display of the process tank temperature, Process tank stirring motor speed control knob and Process tank stirring motor operation switch.
  • The air duct control section contains Blower motor speed control knob, Blower motor ON/ OFF switch, Digital display of air flow rate, Digital display of air inlet temperature (the blower side) and Digital display of air outlet temperature.
  • The system water flow section contains Digital display of Cold / Hot flow rate (depend on the water source) and Digital display of process tank flow rate.
  • The heater section contains Hot water tank low level LED, Hot water pump ON/ OFF switch, Heater ON/ OFF switch and Heater temperature control.
  • The stirring tank section contains Stirring heat exchanger speed control knob and Stirring heat exchanger operation switch.
  • The process tank switches are used to select the heat exchanger type for the water coming from the process tank to pass through.
  • The trainer is supplied with Emergency switch and Trainer ON/ OFF switch.
  • Heat exchangers control valves are used to allow hot water from hot water tank or cold-water source to pass through the selected heat exchanger to perform heat transfer between the process tank water and the hot or cold water.
  • The trainer has two modes of operation, manual mode through the control panel and software using the software.
  • The software allows the measured data to be transferred to an external pc to be viewed and analyzed.
