Air source heat pumps take heat from the air outside and treat it through a refrigerant cycle.
Air source units are more affordable than ground source units.
It is 40% energy saving than air conditioner.
Spraying the compressor to solve the problem of low temperature attenuation
The air source heat pump is separated from the safety of water and electricity, and there is no harmful gas emission. The air source is safe and environmentally friendly.
Easy to install, it could be amounted on the wall or on the top of building
Galvanized steel casing , ss srews , good anti-cossion features.

Comparasion to Electric AC unit
