Public Summary

Are you concerned about your building heating and cooling costs? Then we have a solution for you.

Conventional boilers and heat pumps that operate with COP in the range of 1- 4.5 are being substituted by ATES systems, where subsurface is used to store and retrieve hot and cold water. The current ATES- Doublet system, which has a COP of around 4 and 18 for heating and cooling respectively requires a heat pump for deficiency in heating . This heat pump is a major electricity consumer.

We are developing a simulation tool for ATES-Triplet system, where instead Solar Collectors and dry cooler act as hot and cold water generators respectively to store the required amount of hot and cold water in underground, which means almost free heating and cooling. An additional third well is used in contrast to ATES-Doublet ( two wells). ATES-Triplet has a potential of attaining a 84% energy saving compared to an ATES-Doublet system.

This project is a joint undertaking between university and industrial partners:

  1. Technical University of Eindhoven
  2. Technical University of Delft
  3. Royal Haskoning DHV
  4. Kropman
  5. KWR water
