The present invention provides an air source
heat pump unit system capable of efficient heat exchange and
noise reduction, comprising an installation platform, an exhaust duct, a
sound barrier wall, an air source
heat pump and a fan. A placement plane is provided at the top of the installation platform. An air passage is provided in the installation platform. The exhaust duct is fixed on the placement plane, has a cylinder cavity with an open top, and is provided with a sealed cylinder cover. The
sound barrier wall is fixed on the placement plane and is arranged around the exhaust duct, and an annular isolation cavity is formed between the
sound barrier wall and the exhaust duct. There are multiple
air source heat pumps, each of which is arranged in an annular isolation cavity around the axis of the exhaust duct in an annular interval, and each air source
heat pump has an air outlet connected to the cylinder cavity, and has an air inlet. The fan is arranged in the cylinder cavity, and can transport the gas derived from each air outlet to each air passage. The air source heat pump
unit system capable of efficient heat exchange and
noise reduction provided by the present invention can eliminate
noise, avoid the cold island effect, ensure the heat exchange effect, and ensure the
heating effect.
