The heat extracted is transferred to the hot reservoir, together with heat generated by the electrical supply to the peltier device. This heat is removed by a water-cooled heat exchanger. The flow rates can be adjusted to provide a range of operating temperatures. By varying the electric power into the system, the behaviour of the system at different operating points and temperatures can be established. The thermo-electric Peltier device is positioned in a heat transfer path, between two copper blocks, extracts heat from one block (cold reservoir) and transfers it to the other block (hot reservoir). In order to measure the heat transfer rate, the cold reservoir is fitted with an electric heater.
Instrumentation is provided to measure the temperatures of the blocks, the electric power supplied to the Peltier device, the cooling water flow rate and the cooling water temperature rise.
The Peltier device can also be used to generate a small quantity of electric power when a temperature difference is applied. This effect can also be demonstrated. The heater power is measured , and so it is possible to establish a complete energy balance for the system.

These differ in their characteristics decisively from flow equipment which include the turbo compressors that are common in very large systems. In Piston Compressors the flow rate is mainly dependent on the displaced volume and speed. Smaller refrigeration systems usually have a Piston Compressor. Because the flow rate is a measure for the refrigeration capacity of the refrigeration system, the properties of the compressor are important for the capacity of the whole system. Piston compressors are positive displacement machines. Due to the unavoidable dead space the flow rate drops with increasing pressure ratio.

The heat generated can be dissipated via cooling water connections, enabling continuous operation. The heat transferred can be calculated. Connections for an external heating circuit are provided on the rear of the boiler. An integrated hot water circuit with plate heat exchanger simulates the heating circuit in a house. This allows them to be expanded into a complete heating system using training panels. Different operating points can be investigated by changing the oil pressure after the preset boiler water temperature has been reached.
