Step 1

The pump takes the cooling fluid at low pressure in a liquid state coming from the condenser

Step 2

The fluid abandons the pump in a liquid state and at high pressure

Step 3

The fluid abandons the evaporator at high pressure and after being heated, changes into the steam phase, thanks to the energy provided by the hot source. In this way, we have managed to transfer the waste energy from the process to the cooling fluid, which will be introduced to the screw expander.

Step 4

As the fluid expands to high pressure and temperature, we generate mechanical work at the shaft, coupled to the electric generator. The cooling fluid gives up pressure and temperature during the expansion, but continues as steam, which means we have to insert it into the condenser in order to be able to change it into liquid and initiate the process again.

The performance of the machine is associated with the Carnot cycle. Therefore, the greater the difference we have between the temperature of the hot source and the cold source, the greater the performance of the machine. It is usual that for a hot source temperature set by the process, we achieve greater performance in winter than in summer, as generally the cooling air or water will have a lower temperature.[/vc_column_text][/vc_column][/vc_row]
