The ATES (Heat Cold Storage) of the residential care complex de Tuinen in Woudenberg had a cold surplus for some time. More heat is extracted from the source than is supplied back during the summer through passive cooling of the building. In the long term, this presents a danger to the proper functioning of the heating installation.
Unica Energy Facilities Services was commissioned to upgrade the installation.
Triple Solar installed 340 PVT heat pump panels for the regeneration of the ATES. For this Unica Energy Systems is called the Technical room expanded with a TSA on the source side with new control technology. The heat pump panels provide both evaporator energy to the heat pump and heat to the source when the heat pump is off.
