Energy Efficiency for Power Plant Sector & District Heating Networks

A major potential use of heat pump technology to increase energy efficiency is the energy and power plant sector as well as district heating networks. Chemical, mechanical, endogenous and exogenous processes of all kinds offer themselves as a heat source or heat sink upon which heat pumps can run.

Heat from any kind of exhaust, cooling water or process heat can be used effectively with heat pump technology.

Since both the heating and cooling produced is used,  as a rule of thumb this gives double the efficiency.

 

 

 

 

 

 

 

 


HEAT SOURCES / HEAT SOURCE TEMPERATURES

 

Waste Heat

  • Waste heat from server rooms
  • Climate systems such as chillers
  • Exhaust air from processes 
  • Oil cooling systems for combustion engines
  • CHP plants 
  • Sewers & drains 
  • Process heat from dairies, slaughterhouses

Renewable Ambient Heat 

  • Ground water, soil, air, river/lake/sea

Industrial Heat 

Source heat between 35 ° C and 55 ° C can be used for the production of process heat to 130 ° C.
In the power plant sector , with mechanical processes or particularly in cooling processes in the chemical , pharmaceutical and food industry there is low-temperature waste heat , which can no longer be used with conventional heat exchangers. This is available in large quantities and is for free. Through the use of heat pumps , this low-temperature waste heat can be brought in an efficient way back to a sensible usable temperature level .

 


Simultaneous use of the heating and cooling function

When there is simultaneous use of cooling and heating functions, heat pumps can be added to the system to increase the coefficient of performance (COP) of the heating and cooling modes. This can give impressive energy efficiencies  and CO2 reductions (COP heating + cooling EER = COP integrated).
