1.3 Sewage Source Heat Pump Industry Classification

According to the source of low heat source, sewage source heat pump can be divided into primary sewage source heat pump, secondary sewage source heat pump and water source heat pump. The primary sewage source heat pump directly uses the primary sewage discharged from domestic or industrial discharge as a low-level heat source, which contains a large amount of organic matter and suspended solids, and requires a specially designed heat exchanger and filter device; the secondary sewage source heat pump uses the secondary sewage discharged after preliminary treatment by the sewage treatment plant as a low-level heat source, which contains less organic matter and suspended solids, but still needs to adopt technical measures such as anti-clogging, anti-corrosion and pollution; the reclaimed water source heat pump uses the reclaimed water after advanced treatment as the low heat source, which contains very little organic matter and suspended solids, and can adopt the heat exchanger and filter device of regular design.

According to the heat exchange mode, sewage source heat pump can be divided into direct sewage source heat pump and indirect sewage source heat pump. Direct sewage source heat pump will work medium directly with low heat source direct contact, its heat transfer efficiency is high, but there are also problems such as pollution risk and maintenance difficulty; indirect sewage source heat pump will work medium and low heat source through the heat exchanger isolation, its heat transfer efficiency is low, but also to avoid the pollution risk and maintenance difficulty and other issues.
