H111Q Thermoelectric Heat Pump

H112Q Thermoelectric Heat Pump

A thermoelectric device has no moving parts and uses a direct electrical current to transfer heat from one face of the device to the other.

 Thermoelectric devices have been used for many years for cooling electronic devices and vaccines. More recently due to reduced production costs they have found application in mobile coolers for domestic and recreational use. In the H112Q, the thermoelectric module is held between a heated block and a water cooled plate. The module extracts heat from the block and transfers this, and the input power, to the water cooled plate. An insulated enclosure allows student examination and minimises heat gains/losses from the system.

 The module will also act in reverse and generate a small amount of electrical power if one face is maintained at a higher temperature than the other. This can also be demonstrated.

 Controllable power for the module and heater is supplied by the H112 Heat Transfer Service Unit.

Instrumentation is provided with the unit that allows measurement of the dc power supplied to the module, the temperatures either side of the module, the cooling water flow rate and the cooling water temperature rise. The heater power is measured by the H112 Heat Transfer Service unit.

A bench top accessory designed to allow students to experimentally investigate the performance of a thermoelectric cooler module.

In the H112Q, the thermoelectric module is held between a heated block and a water cooled plate. The module extracts heat from the block and transfers this, and the input power, to the water cooled plate. An insulated hinged enclosure allows student examination and minimises heat gains/losses from the system.

 The module will also act in reverse and generate a small amount of electrical power if one face is maintained at a higher temperature than the other. This can also be demonstrated.

Requires the H112 Heat Transfer Service Unit for operation.

  • Investigation of the effects upon the surface temperature of either face of the module with increasing power.  (Peltier Effect)
  • Investigation of the effect upon heat transfer direction of reversing the polarity of the power supply to the module.  (Thomson or Lenz Effect).
  • Investigation of the variation in open circuit voltage across the module due to the variation in surface temperature difference.  (Seebeck Effect).
  • Investigation of the power generating performance of the module with a steady load and increasing temperature difference.
  • Estimation of the coefficient of performance of the module when acting as a refrigerator.
  • Conducting a full energy balance for the module.
