Heat exchangers between the glycol grid to the Empa “refrigeration network” and between the glycol grid to the static low temperature grid of NEST
The system consists of two heat exchangers E260 and E261. The heat exchangers are installed in the NEST in room A09. The E260 heat exchanger is connected to the low temperature grid on the primary side and to the glycol grid on the secondary side. The E261 heat exchanger is connected to the Empa “refrigeration network” on the primary side and to the Glycol grid on the secondary side. The E260 heat exchanger is used to heat the low temperature grid and provide energy from the low temperature grid to the low temperature heat pump. The E261 heat exchanger is used to supply energy from the TTE network to the heat pump.
