Extra heat gain unit of thermal network
Introduction
Introduction:
The unit makes full use of the work capacity in the large temperature difference between the primary and secondary heat-exchange process. With the primary thermal network heat being transferred to the secondary side, low-temperature heat energy from soil, underground water and sewage can be collected and increased by 30%-40%. This extra heat gain needs no more cost compared with regular district heating system. And the energy consumption of the direct heating system can be reduced by 30% and energy can be saved by 50% compared with electric heat pumps.
Driving source: primary thermal network water
Surplus heat that can be utilized: soil, underground water, urban sewage
Heat gained: used for district heating
