Sewage source heat pump unit
[Product Introduction]: The Star Century sewage source heat pump unit is a hot water equipment developed and produced for places such as bathhouses, h
Product details
Product Features
Low operating costs
Extracting heat from domestic sewage, energy-saving and environmentally friendly, saving more than 50% energy compared to general hot water units, highly efficient and energy-saving
Environmentally friendly and pollution-free
When supplying hot water, the boiler room system such as coal and gas is omitted, and there is no combustion process, no waste gas, wastewater or smoke generated, and no environmental pollution
Stable and reliable operation
The characteristic of constant water temperature makes operation more reliable and stable
One machine dual-use
The unit is equipped with a cold recovery device, which can provide both hot and cold water, with a COP of up to 8.0
Long service life
Anti corrosion design: Due to the corrosive nature of bath wastewater, the copper pipes for the bathhouse specific heat pump are made of rare metal nickel copper, which has a longer service life
Save sewage
The sewage heat exchange end of the bathhouse dedicated heat pump is designed with a large temperature difference of 10 ℃, which reduces the amount of sewage used and can fully extract heat from the sewage, thereby improving the efficiency of sewage utilization

Note:
1. Nominal heating conditions: sewage inlet and outlet temperatures of 15 ℃/5 ℃, hot water inlet and outlet temperatures of 30 ℃/45 ℃;
2. Sewage temperature range: 5 ℃~20 ℃;
3. The maximum outlet temperature of hot water is 55 ℃;
4. Cold recovery and heat recovery are optional parameters. When selecting the heat recovery function, the amount of heat recovered is the same as the input power of the compressor.
