Use of waste heat heat pumps

An efficient option is to utilize the effluent 30-500C in high heating flow temperature (70-800C) heating systems.

In Hungary, a significant amount of thermal water is used directly for heating and in thermal baths. the water used primarily is led to cooling ponds between 30-500C. This is a huge waste of energy, in addition to significant environmental heat pollution.

It is definitely advisable to use this amount of heat for heating purposes with waste heat recovery pumps specially designed for high evaporation temperatures and to release it to the environment cooled to a temperature of around 20°C. This can save a huge amount of CO2 emissions. However, this is just a missed opportunity when using these heat pumps.

It can also be mentioned that in industrial applications, where, in addition to technological cooling, high temperature heating and DHW requirements occur, these heat pumps can achieve very high efficiency in simultaneous systems, thus achieving significant energy savings and high CO2 emissions.

In summary, it can be used:

  • For heat recovery (effluent thermal water) between 300C and 500C
  • For high-temperature (max. Heating flow temperature 820C) radiators for existing buildings.
  • In district heating, to increase efficiency
  • For the supply of DHW to hospitals, laundries and restaurants with high temperatures
  • The maximum available heating flow temperature is 820C
  • In industrial systems for building and process cooling / heating, possibly with simultaneous system design.

Vaporline® GWT heat pumps extract heat from deep well water or waste heat directly or by means of a ballast heat exchanger. (secondary use of thermal waters)
The permissible (directly usable) temperature of the usable well water or run-off thermal water must be between 250C and 500C.

The heating flow temperature can be controlled between 500C-820C.
