  • Hard Copy User manual

The water cooler trainer (AR-019) allows trainees to study the operation mechanism of the water cooler by simulating its cooling cycle and electrical circuits. The educational unit contains all real components of the water cooler such as the compressor, evaporator, condenser, condenser fan, in addition to many components of the water cooler. The trainer is supplied with switches to simulate common mechanical and electrical faults of the water cooler.

  • The educational unit contains the components of a real water cooler in the lower part, while it contains the operation and control panels at the upper part, in addition to the cold water taps with water basin and water drain to simulate a full water cycle.
  • The lower part contains the compressor, water tank, evaporator, condenser, condenser fan and pump necessary for pumping water to the cold-water taps.
  • The water tank contains a water tap to supply water from an external source and a coil through which the refrigerant passes and a thermostat that is connected to a digital display supplied with a button to set the desired water temperature and stop the refrigeration cycle when the desired temperature is reached.
  •  The water tank also contains a float to shut the water tap when the water tank is filled.
  • The pump is connected to a pressure sensor to sense low pressure that indicates that cold water taps are opened so the pump is operated automatically, while when the taps are shut, that results in pressure balance so the pressure sensor sends a signal to the pump to stop automatically.
  • The control panel at the upper part includes measurement panel, cooling cycle diagram, electrical connections panel and faults switches.
  • The measurement panel includes measuring and connection terminals of the compressor, start - up relay, thermostat, condenser fan, thermostat lamp, operation lamp and power meter.
  • The thermostat electrical operation terminals should be connected to the terminals of thermostat lamp, while the thermostat mechanical operation terminals are internally connected to a knob by which the trainee can set cooling temperature.
  • The measurement panel contains power source terminals, overload indication LED, emergency switch, main ON/OFF switch and selection switch to select the thermostat operation mode (mechanical or electrical).
  • The cooling cycle diagram of the water cooler is provided with pressure gauges and temperature digital displays.
  • The electrical connections panel contains 4 indication LEDs for the thermostat, condenser fan, compressor and operation line of the water cooler.
  • The operation lamp terminals are connected internally to the operation line LED.
  • Each component at the control panel is defined by its name that is labeled above it.
